change your opti-spark they are know for this
Just to let you know I changed the fuel pump fuel filter and pressure regulator changed the plugs and wires dis cap and rotor ignition module coil there are no codes present in the computer. just out of ideas of what could be the problem if your wondering why i replaced all that stuff it needed it all most all of it was bad
my car 1997 dodge intrepid runs good for a couple of hours shuts down for 20 minutes backfires and runs again like nothing happen
The starts and pressure drop start it again and it shuts off again
Sounds like a bad vacuum leak, maybe a bad intake manifold gasket?
Ignition module
better check over the fuel system carefully. doesn't sound like it's getting gas.
The alternator is most likely the problem
The Ford F150 cranks and immediately stalls and shuts off. It will crank again, but it shuts off. The guages move back and forth also
Look for a check engine light. If there is no check enigine light, that eliminates the possibility of a bad sensor. Try checking the fuel pressure regulator.
You need to check if your DVD drive has new firmware available. Yes, DVD drives have firmware updates too.
the ignition switch could be bad
