The car car turns over but never starts, There is spark at the coil and there is fuel at the rails although it is low pressure. i had a simaler problem last month but it was the spark plugs that were bad. once i changed those it ran fine untill now. i am completely stumped and hope someone can head me in the right direction.  Post #: 1

I took the distributer cap off to see if water was somehow getting in there since i seemed to only have problems after a heavy rain or snow. I broke one of the mounts on the cap taking it off so i bought a new and put it in and connected all the plugs in the same order. The car starts but definetly sounds like 1 or more of the cylenders arent firing and i have a check engine light. anyone have any insight as to what i messed up? (in reply to c0a8l0v6i8n9) Post #: 4

Double check the wire connections. _____________________________ 2002 Blazer LS 4dr 2WD Auto Trans Hypertech PP III Programmed Flowmaster 50 Series Delta Flow Muffler, C6 Corvette Exhaust Tip TYC Elegante carbon fiber tail lights (in reply to P_F_T) Post #: 5

The one that does not cause a change is the one that is misfiring. We can go from that point. _____________________________ 2002 Blazer LS 4dr 2WD Auto Trans Hypertech PP III Programmed Flowmaster 50 Series Delta Flow Muffler, C6 Corvette Exhaust Tip TYC Elegante carbon fiber tail lights (in reply to P_F_T) Post #: 7

When i did all the spark plugs the engine light stayed on for a day and went away on its own, so im hoping its the same situation. (in reply to rriddle3) Post #: 8
