Check and bleed the fuel system at all points including the pump points. check that the fuel shut off solenoid ( stop button ) is being activated when turned on
after bleed the system crack the nuts at the injectors and turn over until fuel drips from the nut
re-tighten and it should start.

SOURCE: cold start valve problem

if you have an electric cold start valve make sure to unplug it and if keeps apling fuel with electrical conector unpluged that means the valve is not good, but if not then you have an electronic problem, possible a bad cold start sensor or cold start module or cicuit problem, and might be a time to take it to an electrical shop

Was any work just done to this car? Timing belt? It is rare that these pumps go bad but I have seen a few shell out. If you are not familiar with the ALH diesel engine I would not try to replace it. You should take it to a shop that specializes in VW's.

SOURCE: peugeot 106 1.5 diesel fuel problem

well this might be quite a serious one. it all depends if you have the model with the keypad.

if you have the model without the keypad it is resonably straightf orward to check if the stop solinoid has power or not. or if it is stuck in position.

a stop solenoid is an item which perhsps might resemble a spark plug. it usually has a single wire which is conected to the top of it.
if this wire isnt live when the ignition is on then chances are a fuse has blown.
if it is live then remove the complete stop solinoid(spark plug looking thing) and it will have a little plunger and a spring inside. theese can be removed and then the stop solinoid replaced.

you can then turn over then engine and if it the gets fuel to the injecters you know that thats the solution.


Cars with keypads.

if your lucky enough to have the model with the keypad. then for security reasons peugeot decided to place a 5mm think bit of steel above the fuel pump so no one can go fiderling with it.
this plate is held on by shear bolts.

and the only way to remove the plate is by removing then engine from the engine bay and drilling out the sheer bolts and then reasemble the hole thing.

sorry for being so long winded but unless you have the few cars with no keypad. and a fuelpump with no steel gard over the top. you will have to get the spanners out.

How do you bleed a diesel pump jeep Cherokee turbo diesel 3.1 5 cylinder 2001


we dont have this engine here, USA.
but i have the WG jeep book,
starting page 12 , chapter 14


FUEL INJECTION PUMP BLEEDING
(1) If the fuel injection pump has been replaced,
air should be bled at the overflow valve before
attempting to start engine.
(a) Loosen the overflow valve (Fig. 18) at the
rear of the injection pump.
(b) Place a towel below the valve.
WARNING: WHEN CRANKING THE ENGINE TO
BLEED AIR FROM THE INJECTION PUMP, THE
ENGINE MAY START. PLACE THE TRANSMISSION
IN NEUTRAL OR PARK AND SET PARKING BRAKE
BEFORE ENGAGING THE STARTER MOTOR.
CAUTION: Do not engage the starter motor for
more than 30 seconds at a time. Allow 2 minutes
between cranking intervals.
(2) Crank the engine for 30 seconds at a time to
allow air trapped in the injection pump to vent out
the fuel injector drain tubes. Continue this procedure
until the engine starts. Observe the previous WARNING
and CAUTION.
(3) Tighten overflow valve.
HIGH-PRESSURE FUEL LINE BLEEDING
WARNING: THE INJECTION PUMP SUPPLIES HIGH-
-PRESSURE FUEL OF APPROXIMATELY 45,000 KPA
(6,526 PSI) TO EACH INDIVIDUAL INJECTOR
THROUGH THE HIGH-PRESSURE LINES. FUEL
UNDER THIS AMOUNT OF PRESSURE CAN PENETRATE
THE SKIN AND CAUSE PERSONAL INJURY.
WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE
CLOTHING AND AVOID CONTACT WITH
FUEL SPRAY WHEN BLEEDING HIGH-PRESSURE
FUEL LINES.
WARNING: DO NOT BLEED AIR FROM THE FUEL
SYSTEM OF A HOT ENGINE. DO NOT ALLOW FUEL
TO SPRAY ONTO THE EXHAUST MANIFOLD WHEN
BLEEDING AIR FROM THE FUEL SYSTEM.
Bleed air from one injector at time.
(1) Loosen the high-pressure fuel line fitting at
the injector (Fig. 19).
(2) Crank the engine until all air has been bled
from the line. Do not operate the starter motor
for longer than 30 seconds. Wait 2 minutes
between cranking intervals.
(3) Start the engine and bleed one injector at a
time until the engine runs smoothly.

or tank filter line priming before. above.

Have starting trobel do ihave lines on wrong


That's hard to say from here, I know it will take some time for the fuel to pressurize the injector system before it will start, does the system have a bleeder valve located on the injector lines? Have you checked the fuel filter and fuel pump and fuel pump fuses? Why did you change all these parts to begin with? Did you check the owner manual for a fuel pump shut off emergency switch? I hope one or some of these suggestions help, it's hard to answer your question without knowing more about the problem!

I have to pump the throttle several times and then it starts sometimes and sounds like backfireing allthough its feul injected!


'pumping' a fuel injected engine is NOT like the old days (like with a carb)-if you hold the petal to the floor, it shuts off the injectors-NO petal, the injectors pulse (and dump fuel to an engine that is slow to start). If you are having hard starting, chances are good you have a flooding condition-leaking injectors, leaking O-rings, a damaged fuel pressure regulator could all be re3asons for your hard starting (and backfiring from a flooded engine). You should try to HOLD the petal to the floor and see if that helps-if it does, you should get the fuel regulator checked, replace the injector o-rings, check fuel pressure and might even need to consider replacing injectors themselves (or having them cleaned).

Dose a 2000 taurus lx have a single or dual port fuel injection and is the coil pack for one cylinder or is it a pack for all cylinders?


depends on the type of engine. DOHC engine has coil on plug ignition system where the OHV has a coil pack with spark plug wires going to it. Both engines only have one fuel injector per cylinder.

My 2001 Saturn, will start but not stay running. We have checked the fuel pump and all fluids. Did a compression check this morning, fuel injectors are not injecting fuel into fuel rail. Why is engine...


You said, 'fuel injectors are not injecting fuel into fuel rail' but it's my understanding that the fuel rail gasoline is supplied by the pump, and the fuel injectors just pulse to allow fuel to get to the cylinders. I would check out the fuel delivery problem further. Check for pressure in the fuel rail that is within specs.

If not, then the pump or fuel pressure regulator may be the problem. Check the fuse for the fuel pump. If good, then the pump may be bad in the tank.

Good luck on this.

I fixed used injection pump to engine and is not starting,i check oniy to fine out that the pump is not injecting fuel to the injectors.the timing is good.it is nissan navara 2000 model


1) There could be an air lock to the fuel system, try to bleed the system.
2) If the fuel is reaching the injector pump & not supplying to the injectors nozzles thn the pump needs attention.
Hope this helps!

I have run my ute low on deisel after filling it up it doesnt want to start .


You may have put undue stress on the fuel injection pump or on the supply pump. Check the fuses for each of these first. If they check out, you will need to test fuel pressure both before the fuel filter and at the injectors. If it is an absolute no-start, the injection pump has probably failed. If it is a hard start or stalling problem, it could be the supply pump, or the filter could be clogged w/sediment from the tank. Post results and details to have the problem narrowed further.

Help w 1994 chevrolet truck


This injector set-up needs a specific fuel pressure supplied to the fuel rail to even start, much less run properly. The fuel pump is immersed in fuel inside the gas tank to keep it cool and not burn up. Running the fuel level low causes more heat in the pump and interuptions in proper fuel pressure. AC/Delco pumps have proven to be a reliable fix, the aftermarket pumps only last for a month or two sometimes. Check fuel pressure under the hood and power and ground to fuel pump at electrical harness at top of gas tank. This truck needs a fuel pump.
