Chev pickup no spark no injector spray 1989-1995 V8
http://autotechviewpoint.com/tipjar Intermittent problem. Chevrolet pickup 5.0 L no spark and no injector spray. We could hear the fuel pump running. BUT that is not a guarantee that there is enough fuel pressure, but with no spark, we figured it was an electrical problem somewhere.

Buick Century missing, Back fire through intake, stalling, loss of power, no start when warm.
Will not start when hot after a 5-7 min run, even WITH starting fluid, let it sit for 1-2 Hrs, and will start, and run, but only for a few.
replaced Ignition Control Module, Crank position Sensor, fuel filter, Have spark at all 6 plugs, injectors are receiving power, Cleaned IAC Valve, can not figure it out.. Back fire through intake, Major loss of power, and runs bad, and smells just as bad as it runs. Seems to idle good with no miss, but give the throttle a quick punch, and you can hear it miss.

How To Clean A Ford MAF Sensor - Simple & Effective
