check for spark, no spark, no fire engine wont run, possible bad ignition coil, wire from coil to distributor cap, no power to ignition coil from ignition switch (rare) wire broken to ignition coil (even rarer)

1992 GMC K1500 Starts then dies


I saw what you replaced, didn't see any testing? Any applicable trouble codes? Use a gage and check proper fuel pressure, TBI--9--13 psi. As an example, 5 psi fuel pressure makes a nice looking injector spray pattern, but, 5 psi won't start and run a v8. My opinion.
Could be other issues.

I replaced the fuel pump and fuel filter on the 1992 Van. I have very little pressure at the injectors and they will not open and spray the fuel. What can the problem be? I can hear the pump run in the...


This van is TBI right? then its only 14psi of fuel pressure. to check fuel presssure a adapter is needed at the filter. I would verify fuel pressure first.

I have A 1991 GMC SIERRA, 350,no fuel no spark, have fuel to the tbi, changed coil, ignition module, tested pick up coil good, check engine light comes on with key, fuses good. I'm running out of ideas....


Do you have power to the injectors? One of the wires to the injector will come on for a couple seconds as soon as you turn the key to the on position.The computer controls the ground side. If you do not get power to one of them start looking for an open circuit. The same power source will also go to your ignition coil and ignition module. If you do not have power on the pink wire to the coil apply a temporary fused battery power source to it and give it a try, this will also power up the injectors.
Check it out and let me know.

I have a 1992 sierra pickup that will turn over


Check for fuel pressure at the injectors. Is your fuel pump good? IS your fuel filter clogged? Plugs and wires good? Timing off at all? Good coil?
