Injector pulse is driven by the computer from the signal it receives from the ignition module. Check to see if there is spark because that could also be an indicator of a failed module or distributor component but having spark does not eliminate the module. It does eliminate the pole piece. If there is no spark and no injection pulse, you have to check for voltage to the B+ side of the coil. If it is there, remove and repair the distributor. If it is not there, you have to trace to see for a breakage, loose connection, bad ignition switch etc.

If is were a betting man, I'd say it's either the injector fuse or the ignition module.

If you have spark at all the plugs, the crank sensor should be ok. You should use a gage to check fuel pressure? I don't know engine size? For the 3.1L engine, my info says 40--46 psi.
It is possible to have spark at the plugs, but, the computer doesn't see rpm signal. If that is the case, no fuel injector pulse. The purple wire with white tracer carries rpm signal from ignition module to pcm, that wire has dc pulse, engine cranking. If nothing there, have to check ignition module.
How long since a tune-up? Any applicable trouble codes?

Could be loosing power or pulse to the injectors. I would check for power and pulse ground at the injectors and see if you are loosing one or both.

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.

1993 s10 2.8 tbi the fuel pump fails to pressurize when the key is tunred on, and i have to fuel injector pulse. when a jumper wire is attached i can pressurize the pump but i still have no injector pulse.


There needs to be 60 PSI of fuel pressure in the system to have the fuel injectors to work. There is also a fuel pump relay on the fire wall just left to the brake booster, There is two relays there, i just can not remember which relay is which but try switching the relays with one another. Also check the fuses to the fuel pump and ECM, and the fuel pressure from the shredder valve. Good luck and keep me posted, not a bad Idea to also replace the fuel filter, and that is located at the inside frame rail under the drivers side.
