Could be a bad coil, or ignition module right by the coil. Both will cause this. If you loose fuel pressure, it would be the pump. But pumps will usually start chugging before the engine dies. Most times it is the coil.

SOURCE: cold start valve problem

if you have an electric cold start valve make sure to unplug it and if keeps apling fuel with electrical conector unpluged that means the valve is not good, but if not then you have an electronic problem, possible a bad cold start sensor or cold start module or cicuit problem, and might be a time to take it to an electrical shop

i think if you checked the sparking plugs and map sensors then check your distributer its maybe not delivering the current nedded to perform the spark to some of the cylinders

Did you ever get to the bottom of this problem? My car has the same codes- dealer says it might be the fuel pump relay. Wondering what you found out?

I got a 1994 gmc s15 jimmy with the vortec 4.3 it idles rough but whaen i drive it give it gas it runs great what would cause that.


sounds like it could be a problem in the IAC circuit. The Idle Air Control valve manages how much air gets into the engine while @ idle. It receives commands from the ECM based on inputs from at least the mass air flow, coolant temp, throttle position and oxygen sensors

98 honda shutts off and will not start until cooled off


you say the engine shuts down when it gets hot if it runs rough before doing so it could be the coolant temperature sensor allowing the engine to  overfuel  if the engine cuts out in a couple of seconds but sounds smooth it could be the fuel pump , if it cuts out instantly its electrical.
