Is firing order the same as cylinder number placement? If not can you please help me on this? I have a 2000 nissan quest. It is having a misfire in cylinder number 6 but where is that? I have a picture...

The diagram you have is correct. Number 6 is the cylinder to the far right and next to the radiator.
The firing order is how the plug wires are connected to the distributor cap or coil.
Keep in mind if you have a trouble code 306 it could also be caused by a faulty injector or mechanical problem.

No power after 4000 rpms

This sounds like a fuel pump or fuel filter problem.
The 1988 Jetta has two fuel pumps. The "main" one under the car directly in front of the gas tank on the right hand side. The other fuel pum is in the tank. You can access that fuel pum by removing the round access panel in the trunk towards the back seat.

You'll need a fuel pressure gauge. You can usually borrow one from a large auto parts chain store.

System Pressure
Connect Pressure Gauge (VW 1318) between line from fuel distributor to cold start valve and
test port connection on lower chamber of fuel distributor, using Adapter Fittings (VW 1318/5).
Test port is sealed by a threaded plug. Bridge fuel pump relay with Jumper Switch (US 4480/3).
Disconnect wiring from Differential Pressure Regulator (DPR). Open valve on pressure gauge
(points at cold start valve line when open) and activate fuel pump. System pressure must be 75-
82 psi (5.3-5.8 kg/cm2 ). If pressure reading is low and fuel pump delivery quantity is good,
replace pressure regulator.
If pressure reading is high, disconnect fuel tank return line from DPR. Repeat test. If reading is
correct, check for plugged return line. If reading is incorrect with line open, replace DPR.
Differential Control Pressure
Close valve on pressure gauge. Activate fuel pump with jumper switch. Leave DPR
disconnected. DPR reading should be 2.9-7.0 psi (.2-.5 kg/cm2 ) less than system pressure. If
pressure is incorrect, disconnect lower chamber return line and measure volume.
Close open port to diaphragm pressure regulator. Activate fuel pump with jumper switch. Fuel
volume should be .14-.16 qts. (.13-.15L) for period of one minute. If volume is correct, replace
DPR. If volume is incorrect, replace fuel distributor.
Close valve on pressure gauge. Install Test Harness (1315A/1) between DPR and vehicle
harness. Set multimeter to DCA 200 mA scale. Connect multimeter to test harness. Disconnect
wiring to coolant temperature sensor. Connect 15 k/ohm side of Test Resistor (VW 1490) to
sensor wiring.
Turn on ignition and fuel pump. Differential pressure should be 10-17.5 psi (.7-1.2 kg/cm2 )
less than system pressure. DPR current should be 50-80 mA. If pressure is incorrect and current
is correct, replace DPR.
If both pressure and current readings are incorrect, remove test harness from DPR. Ensure
resistance of DPR is 17.5-21.5 ohms. If reading is incorrect, replace DPR.
If reading is correct, check ground from temperature sensor to cold start valve. If ground is
good, check power supply fuse. If fuse is okay, check terminals on ECU connector. If connector
is okay, replace ECU.
Residual Pressure & Internal Leak Testing
Open valve on pressure gauge. Operate fuel pump for 30 seconds. Pressure can drop to a
minimum of 38 psi (2.7 kg/cm2 ) after 10 minutes. If pressure drops below specification, inspect
fuel pump check valve and all fuel fittings for leakage.
NOTE: Pressure and leak testing does not include checking cold start
FUEL INJECTION SYSTEM - BOSCH CIS-E -1988 Volkswagen Jetta Page 1 of 3 11/25/2011
If there are no leaks, check airflow sensor plate clearance. If plate clearance is correct, replace
diaphragm pressure regulator and repeat leak test. If pressure drop is not within specification,
replace fuel distributor "O" rings.
Transfer Pump Delivery Volume
Check voltage supply to pumps. Connect Jumper Switch (US 4480/3) in place of fuel pump
relay, on relay panel. Remove fuel filler cap. Disconnect and plug off Black fuel line from
sending unit.
Connect hose to sender port and place in measuring container. Turn on fuel pumps. Minimum
transfer pump delivery volume should be .42 qts. (.4L) in 10 seconds. Reconnect fuel line to
Main Pump Delivery Volume
Check transfer pump (if equipped) and fuel filter. Disconnect fuel return line and place in
measuring container. Switch on fuel pump with jumper switch. Check fuel pump delivery
volume for 30 second period. Delivery rates are given with voltage reading at pump as volume
will change with different voltages.
Minimum delivery volume for Fox, Quantum and Quantum Syncro models is .71 qts. (.68L) for
30 seconds with reading of 11.4 volts at fuel pump. Minimum delivery volume for other models
is .62 qts. (.59L) with 11.4 volts at fuel pump.
Fuel Distributor
Check sensor plate adjusting lever and fuel distributor control piston for smooth operation.
Disconnect fuel injector lines at fuel injectors.
Remove fuel pump relay and bridge fuel pump circuit. Use Jumper Switch (US 4480/3) in place
of fuel pump relay. When pressure has built up, turn off fuel pump. Move sensor plate from rest
position to end of travel.
Uniform resistance should be felt during entire movement. No resistance should be felt on
quick return to rest position. Connect injector lines. Install fuel pump relay.
Injector Quantity Comparison
Remove fuel pump relay, from relay panel, and install Jumper Switch (US 4480/3) in off
position in place of relay. Attach Fuel Quantity Analyzer (US 4480) to bumper and secure in
place. Remove injectors from cylinder head with fuel lines attached. Check and replace fuel
injector "O" rings as necessary.
Check tightness of injector insert (2-piece inserts). If inserts are loose, remove and clean
threads. Use sealing compound when installing upper insert. Replace sealing washer that goes
against cylinder head below lower portion of insert. Lubricate injector "O" rings with gasoline
and install injectors, with fuel lines connected, into fuel quantity analyzer tubes.
Ensure lines are not kinked or bent. Loosen fittings to align fuel lines and retighten. Remove
rubber boot from airflow sensor housing above sensor plate. Turn and lift setting screw and
adjusting slide of Sensor Plate Adjustable Holder (VW 1348/1) into upper position. This
simulates full throttle operation. See Fig. 11 .
FUEL INJECTION SYSTEM - BOSCH CIS-E -1988 Volkswagen Jetta Page 2 of 3 11/25/2011
Fig. 11: Sensor Plate Adjustable Holder (VW 1348/1)
Place sensor plate adjustable holder on airflow sensor housing with holder centered over plate.
Pointer on edge of holder base must point toward center of fuel distributor. Push adjusting slide
of holder down onto stop.
Turn adjusting screw clockwise until magnetic end touches sensor plate retaining bolt. Activate
fuel pump with jumper switch. Turn adjusting screw of holder counterclockwise until any one
injector starts to deliver fuel. Turn off jumper switch and empty fuel quantity analyzer after
taking sample.
Idle injection quantity is measured first. Lifting adjusting slide of holder to first stop simulates
idle position of sensor plate. Activate fuel pump until fuel level reaches 20 ml on scale of any
Check that all injectors have identical spray patterns that are even and cone-shaped. If not, raise
sensor plate up quickly to full lift position and release. Repeat idle quantity test. Compare
amounts of fuel delivered by all injectors with analyzer held level. Maximum difference in
delivery quantity between injectors is 3.0 ml of fuel.
If fuel delivery quantity differs between high and low levels by more than 3.0 ml, interchange
injectors and repeat test. If difference of delivery quantity changes with injectors, replace
injectors. If difference of delivery quantity does not change with movement of injectors, either
fuel lines are pinched or fuel distributor is defective.
Measure full throttle injection quantity. Empty analyzer into fuel tank and reinstall injectors in
analyzer. Lift adjusting slide of holder to last stop to simulate full throttle position of sensor
plate. Activate fuel pump with jumper switch until fuel level reaches 80 ml on scale of any tube
of analyzer.
Check that all injectors have identical spray patterns that are even and cone-shaped. If not, raise
sensor plate up quickly to full lift position and release. Repeat full throttle quantity test.
Compare amounts of fuel delivered by all injectors with analyzer held level. Maximum
difference in delivery quantity between injectors is 8.0 ml of fuel.
If fuel delivery quantity differs between high and low levels by more than 8.0 ml, interchange
injectors and repeat test. If difference of delivery quantity changes with injectors, replace
injectors. If difference of delivery quantity does not change with movement of injectors, either
fuel lines are pinched or fuel distributor is defective.
Check fuel injectors for leakage immediately after delivery quantity test is complete. Set sensor
plate in rest position. Activate fuel pump with jumper switch for 2 minutes. Injectors should not
drip. Replace injectors that drip.
See image. Fuel filter is probably located on the frame between the engine and fuel tank.

My Engine light is on and diagnostics check read injector 5 can any one help me with this?

This would mean there is a problem on the # 5 cylinder injector. The wiring to the injector can be checked with a special light for the injector harness.
The tool may be available on loan from Autozone, Advance, or Oreillys autoparts stores. Each has a tool loaner program.

What you will be trying to determine is if the power is reaching the injector through the wiring harness. If the tool lights up when the engine cranks, then the power is going to the injector. The injector must be bad if it is not working when it has power.

The injectors are not bad to replace if you can reach them. You will have to deal with the accumulated fuel pressure in the fuel rail. There is a tap for testing fuel pressure and sometimes there are tools in the loaner programs which can make this an easy project. Just relieve the pressure and then remove and replace the bad injector.

You can use your Web browser and get the cylinder layout diagram for your engine so you know which is the #5 cylinder.

Besides buying the injector, it may be possible to look at a new electronic unit if the # 5 wire is bad.

I hope my solution is helpful.
By using this device, you would test

Hi, I have vw bora 2001 1.6 my car is misfiring when you put your foot down. I change the spurk plugs and coils still no help and the computer dont show nothing. Can anybody help me?

If the computer doesn't show anything and the car is misfiring, I would check for plugged fuel injectors or non functioning fuel injectors.

Listen with a stethoscope for clicking at the fuel injectors. It should sound rather loud and distinct with the stethoscope.

Use a noid light to attach to the detached harness connector that usually is connected to the fuel injector. It should pulse as the engine runs.

One can, also, disconnect the fuel injectors one by one until no change in engine idling is observed.

This would tell the technician which fuel injector is not firing.

Try fuel injector cleaner in the gas tank to clear out the fuel injectors.

Also, and Oxygen sensor that is going bad can cause erroneous information to be sent to the computer and cause a general misfire across all cylinders due to decreased fuel injection.

Good luck with this repair.

2000 S10 with 4.3 V6 has P0305 trouble code, replaced Cap, rotor, plugs, wires, still missing and running sluggish and hesitating. could Cat. Converter be bad? occassional rotten egg smell and lots of...

P0305 is the generic DTC (Data Trouble Code) for cylinder #5 mis-fire detected, and you have already eliminated the ignition tune-up parts as the problem, the next procedure should be a compression check, at least on the #5 cylinder to rule out the possibility of a mechanical mis-fire. If the compression is good then check the pick-up coil located inside of the distributor for any damage, and there is a possibility that a fuel injector is faulty or has a broken fuel line, and if the upper intake manifold is removed, and the large wire connector and fuel lines replaced back on the fuel injector assembly, then cycling the ignition key off and on several times will show if there is a fuel leak on any of the fuel injector lines, and removing the fuel injector nozzles from the lower intake manifold and then cranking the engine over (have the ignition coil connected but be certain to have the ignition coil high tension wire to the distributor cap grounded) will show if any fuel injectors are not firing or have a plugged up nozzle. The original fuel injector assembly in that vehicle has the actual fuel injector inside of the injector assembly block and the fuel travels through a small plastic tube out to a fuel nozzle attached out on the lower intake manifold for each cylinder, and a replacement fuel injection assembly is made a lot better and will have the fuel injector mounted out from the injector assembly block on the end of a larger heavier plastic tube with covered wires running back along the fuel tube to the injector block. Do you remember what the #5 spark plug looked like when you removed and replaced it and did any of the spark plugs have a black sooty carbon fouling? The #5 cylinder is located at the rear spark plug on the driver side and here is a firing order diagram to assist you. The catalytic converter would not be the suspect and moisture or clear liquid dripping from the tail-pipe is an indication that the catalytic converter is functioning properly, unless coolant or liquid is running out of the tail-pipe, then there might be a faulty intake manifold or cylinder head gasket, and a rotten egg smell is usually caused by poor fuel if the smell is coming from the exhaust, or an over-charging battery condition, (voltage at the battery should be between 14 an 16 volts when the engine is running) and let me know if you require the procedure to remove the upper intake plenum, or if you require any further assistance.

89 ford f150 in-line 6 cylinder. i have replaced a few injectors both fuel pumps and filter. idles like a dream. when i hit the gas it studders but doesn't die. need more info ask. any ideas?

This is for a 1989 Ford F150 In-Line 6-Cylinder (4.9L) wrongly posted by the Asker under a 1986 Ford Mustang....

Fuel Injector Pressure Regulator. Look it up on line at any of the reputable auto parts websites to get an idea what it looks like.
There should be a Rubber Vacuum Line coming from this (the Regulator is located on the Fuel Line prior to the Fuel Injectors) to the Intake. Take this Line OFF. If there is gas in that line = The Fuel Injector Pressure Regulator diaphram is broken and the Fuel is being dumped into the Intake and NOT being advanced onto the Fuel Injectors; and the Regulator must be replaced.
Let me know if this helped.

2003 vw jetta tdi fuel filter

It is on the passenger side right behind the washer fluid fill tube. You can follow the fuel lines (look like 1/4" black tubes, some are clear) from the injector pump to it. It is a caniser a bit bigger than a normal looking oil filter and sits between the washer bottle and the metal that forms the wheel well. It is held in by a screw type clamp about half way down the cylinder. Probably isn't the fuel filter unless there is air in the lines to the injector pump or they didn't bother to fill the fuel filter up with diesel after putting it in. There is not a fuel pump in the tank in these cars so everything is sucked up by the injector pump and it needs to be primed properly.
