Be sure to check for codes--it could easily be a bad Crankshaft Position Sensor or a bad Camshaft Position Sensor.

I checked with 2 scanners,genysis and mindreader no codes,no pending codes ,cant believe it didn't pick up a misfire,whatever it is its not emission related... eddie

I checked with 2 scanners no codes ,it didn't record a misfire,does it have a crank sensor if it has a dist.. . eddie

You have a crankshaft position sensor and camshaft position sensor. Did you check all under hood and under dash fuses?

I have a blue spark coming out of the coil,very slight spark at the plug,every thing corroded inside the dist. cap like frosted green,I can understand the slight spark but the backfire still seems like timing.dist. turns OK... eddie

Replace rotor, distributor cap, wires, and spark plugs (ACDelco only).

I did all you suggested and the truck is running perfect.you are so far the best advice I've received .thanks for your help,response,and all you gave to me... eddie

What size engine did the truck have?

The truck has a 4.3 motor,the symptoms I had I never would have thought the corrosion in the dist could cause a out of time act.this truck was running fine 2 days ago with the same corrosion... eddie
