SOURCE: 1995 jetta 2.0 fuel pump

ok could be a few things.

Have you changed the inline fuel filter? these usually have paper filter elements and after a while can be clogged with moisture which blocks fuel flow. The fuel pump will still have good pressure but the fuel rail will lack the flow required and you may burn out an injector as its running too lean. Secondly, the MAF sensor, could be dirty, clean it with electrical cleaner.

I think its more likeylt the fuel filter blocked. Try and bypass it if possible, reset the ECU and try agiain

if by no injector pulse you mean no electrical signal to injector, no that wont do it, that would be related to a bad ECM

I would first check to see if you have good fuel pressure; if not the fuel filter and/or pump would be suspect.

If you have good fuel pressure but no signal to the injector(s) the ECM is probably the problem

No injector pulse


what vehicle? injector pulse controlled by computer. the computer recieves a pulse from crank angle sensor, or distributor pick up, etc.
then controls injector pulse. Mass air flow on some vehicles determines spray pattern

1992 mercury sable will turn over but wont start


Make sure battery has a full charge. If it cranks good but won't start, check the basics. Have a helper crank it while you visually check for spark at the spark plugs, if spark everywhere, use a gage and check proper fuel pressure. I looked at info for the 3.8L engine, 35--40 psi. Also, after you build fuel pressure, turn off the key, see if fuel pressure holds for a bit? If the pressure drops like a rock, check for fuel pressure leak. Check the vac line for fuel pressure regulator, if it has gas in it, the regulator is faulty, or a leaking fuel injector. The pressure could also drain back through fuel pump.
Also, check fuel injector pulse, engine cranking. Any applicable trouble codes?
Smell of the crankcase oil dipstick, if it smells like gas, either you don't change oil and filter very often or the engine is running very rich for some reason.

1989 Ford Ranger 2.3l. Won't start. Does not have injector pulse. Has spark on all 4 passenger side wires. Has at least some fuel pressure. Timing and belt good. This was a progressive problem in that...


The fuel pressure has to to 35 to 45 psi. And no low fuel pressure will not cause no injector pulse.The veicle sounds more like a idle air control problem why? because as you stated it runs rough when it does start.Get it to start sysle the key you will hear the fuel pump go on cycle it three times then start it up. when the vehicle warms up take the idle air valve out and clean it with carburator cleaner or even brake cleaner you may even want to do the throttle body itself this should help with the hard start up and rough running

Car stalled at30mph and wont start back up


  • Cranks but no start condition-do below to determine whether it's fuel or spark issue:
  • Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
make sure it is getting enough gas pressure

Ran out of gas. Put gas in but will not start. Had fuel pump checked ok. Had fuel filter replaced. Checked if fuel was getting to injectors ok. Getting spark. Will try to start if starting fluid sprayed...


Check your fuel pressure regulator. Remove the vacuum line attached to it and hook a fuel pressure gauge to the schrader valve on the fuel input line. The gauge should read at least 40 PSI, probably closer to 50-60 or more.

If it's lower than that, you're not getting enough fuel to the engine. It may also be stuck shut, meaning that you're putting in too much fuel.

If you find that the exhaust smells of fuel after cranking for awhile, there's a good chance that you're flooding out due to a faulty FPR.

99 Tahoe engine cranks, wont start


You need 3 things.
Compression
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 63-64 lbs.
If you have all 3 then move on to injector pulse to all injectors.
I think each injector is on a separate driver on that one.
Check for pulse to all of them.

You may be weak on fuel pressure . even a couple of lbs low on a cold start will cause a no start.
Double check cold start cranking fuel pressure. If under 63-62 lbs you have problems.
one test is to give it a squirt of carb cleaner not starting fluid. If it starts then you have a fuel pressure problem.
Run the full fuel pressure test and post back pressures.
Here is the guide lines on testing.
Hard to start cold.
Check cold start fuel pressure.
Check engine running fuel pressure.
Check engine running on the road fuel pressure.
Then shut it off and watch for fast leak down.
Pinch off at rubber part or block off return line and check full pressure.
Later V6 and V8 gm engines should have 60-66 fuel pressure.
Cold start should be 64-65 lbs of pressure.
If you do not have full fuel pressure on a cold start the injectors will not squirt fuel.
Do not leave home without it.
Engine running should be 60-66 lbs pressure depending on engine load.
Full pressure with return pinched off should be 75-85 or more.
And if it has a fast leak down after shut off you have a leak.


The 75-85 is only a check on the capable full pressure of fuel pump.
If you can not find the rubber return line check full pressure by plugging return line or just or the true full pressure can be taken direct at the end fuel filter.
What are the pressure readings that you have done.
What are your cold start pressure readings?
Post back what you have.


The other thing to that is common is the (ICM) under the distributor cap. There is a breather screen on the bottom of the distributor that get's clogged with dirt causing condensation promoting corrosion, this was gm TSB for replacing the cap and rotor to make sure it's clean.

Good luck and hope this helps. Merry Xmas.

The fuel pump pumps but on start up it dies


Flel regulator will only affect max fuel pressure only will not cause it to not start. try replacing fuel filter first if still does not get fuel then you need to see if it is fuel related or if you have a spark at the spark plugs, pull off a spark plug boot and put screw driver in it hold 1/4 inch away from bare metal and crank engine if you get a spark then it's fuel relateed if no fuel it can be the crank shaft sensor or the cam shaft sensor. let me know if it has fire.
