Hard to say.
The codes in the 100 and 300 range could be fuel related, but you would have to check the specific codes one at a time to find out.

I have a problem with toyota conquest 1.6. the car slow down it selt. i have changed petrol bump but still, i have serviced carburator with no luck. Please Help.


You...serviced...the...throttle body, then. It's injected, no carburetor. And changed the ...pump? What year is this car (so we get on the same page)?
Can you scan the computer for trouble codes?
If it is fuel injected, get a fuel pressure reading. You didn't say if you had changed the fuel filter. That's why I said to get the pressure tested.
It does sound like a fuel problem. Good luck. And try to get the trouble codes.

Transit pump code p0216 how can i fix this


P0216 DTC - Injection Timing Control Circuit Malfunction and this means the diesel fuel injection pump has a timing failure. This could be that the injection pump timing needs adjusted OR the failure is internal to the injection pump and therefore non-adjustable.

NOTE: If your vehicle is a Dodge Ram with Cummins engine then be aware that fuel delivery problems frequently cause this code. Prolonged fuel delivery problems can cause injection pump failure!

Symptoms of a P0216 DTC may include:
Low power
Crank, but no start
Hard start
Displays an intermittent stumble or miss
Engine may start and then stall
Engine may appear to drive fine but surge at idle


The most frequent cause of this code is a bad injection pump due to poor fuel delivery. Fuel delivery problems could be:
A plugged diesel fuel filter
An in-tank blockage
Air in the fuel due to a cracked in-tank fuel ine above the fuel level
Bad transfer (lift) pump
Injection pump out of time


Possible Solutions: First, simply check if your injection pump timing is adjustable. If so, check the timing and adjust if necessary.

If you think that you may have a fuel delivery problem, then check the lift pump operation. On Dodge Ram with the Cummins engine, the lift pump should produce about 45 oz of diesel in 25 seconds of operation. This can be performed by disconnecting the fuel hose from the injection pump and pumping the fuel into an approved container. Bump the engine over but do not start it. Then the lift pump will operate for 25 seconds. If the fuel is aerated, then check/repair fuel line and recheck.

With the fuel hose connected the fuel pressure should be 10psi. If the fuel delivery tests fail, replace the diesel fuel filter and recheck.

If it still fails then verify there are no restrictions in the fuel tank

Then replace the lift (transfer) pump. IT SHOULD BE NOTED that if this code surfaced after a routine fuel filter replacement or if you have any of the above symptoms after routine fuel filter replacement, then suspect the fuel transfer pump. This occurs because even a weak transfer pump can still provide enough fuel for the engine to run. But when the fuel system\'s prime is lost due to fuel filter replacement, it may not restart again without fixing the fuel delivery problem.

If you found your injection pump to be bad, the lift pump should be checked for operation to protect the new injection pump. This is because weak or low output from lift pump are common cause of injection pump failure. There are some aftermarket kits that can be purchased to warn the operator when the fuel pressure/volume drops to level that could damage the injection pump.

Hope this helps (remember to rating this free answer and leave a testimonial comments).

At 2800 rpm the car starts bucking. The injecters have been replaced. The code reads, malfunction in the injecter circuit. Two different shops have tried to solve this problem. 7 months later, no luck! I...


Could be the fuel pressure is too low, to supply enough fuel, at that engine speed. I've also seen a lot of corroded injector plugs on late 80's model Nissan vehicles.

Throttle body pops when i give the car alot of gas


This is normally a sign of a lean mixture where the fuel injection isn't injecting enough fuel into the engine. It can be from having an inadequate amount of fuel delivered to the engine from the tank, or it can be from the injection system having a malfunction where it isn't injecting enough fuel into the engine. You should start off by checking the trouble codes in the onboard diagnostic system. From there you should check the fuel pressure. Odds are these tests will show a problem and you will know which way to proceed.

Failed OBDII Diagnstic trouble codes P0761 and O1744 What does this mean?


code P0761-
Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid 3 valve
- Shift solenoid 3 valve harness or connectors
- Shift solenoid 3 valve circuit is open or shorted
P0761 FORD Description Shift solenoid valve 3 is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position. When is the code detected? The P0761 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off code O1744- is not a code these are the ones I have found that come close

I have a 95 Isuzu Trooper that had bad gas from the store, it started missing every know and then, then one day it just killed on me, we drained the gas, changed the spark plugs, but know you accelarate it...


you probably have a build up of "gunk" in the fuel pipe or injection system, the popping and stalling when accelarating could be tied to this (the valves probably gunked up) their is a kit wal-mart has that may help its a fuel injection (carb) cleaner the kit you can do at home and comes with directions or it can be done in the automotive garage.

Car trouble,


could be a dirty fuel inject problem
run the fault code first to check for cam/crank position sensor problems or other electronic faults
and go from there
a dealer charging $80.00/ hr is cheap as where i am it is $145.00 /hr
