Check fuses first , then coil. Let me know


it's more likely something else. like mike said check you coil and fuses, if they check out try the alternator. if you haven't done them in a while, plugs and wires are always a good idea too, though i'm certain they aren't your problem.


Also check fusible links under hood .One should be for ECM .Also bad crankshaft position sensor will do this."It doesn't know when to fire the plugs."

As all above, never presume the worst as this can become costly!!! Always go back to basics - Is there fuel in the combustion chambers, is there a spark, is the top of the engine connected to the bottom i.e cambelt / timing chain broken??


i believe its the icm modular

Janier did you ever get an answer to your problem? Mine is doing the same thing.

I'm having same problem what was it?


If you are having problems with fuel delivery, the ground to the fuel pump could be your problem. If the wire connection to the frame is rusted ,corroded that would do it.
