1995 GMC Sonoma Repair Question
1995 GMC Sonoma crank no start
1995 GMC Sonoma 4 cyl Two Wheel Drive Automatic 122000 miles
If someone could help me while chasing my tail - that would be awesome!
Here's what I have
95 Sonoma 4.3 TBI Crank No Start -
replaced, fuel pump, sending unit, both injectors, ignition coil, spark module, pick up coil, ecu - no change @ all
I am thnking electrical at this point when i checked coil both sides had power coming from it. I think at this point being overwhelmed annoyed whatever has me running in circles -
any suggestions, solutions would be great
Cranks but no start condition-do below:
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.

thank you for response !
injectors do not pulse, there is no spark, there are no codes, ecu is Good, and replaced numerous other components, I feel like I am over looking something very small... looking @ ignition switch now, and behind the cluster and pointers would be great.
thank you again
