Originally my car would not start, replaced the ICM, it then started but ran rough, so I replaced the coil pack, wires and plugs. Still running rough, especially when accelerating around 40 mph.
Took it to a shop and they said that #5 injector was not firing, not sure why. So I replaced the injector. When it starts cold it works, within 5 minutes it stops. Now I don't think it it firing at all.
I saw on another post about checking for 12v and pulse. With key on I have 12 volts on one side of the connector, also when running. When I hook up a test light to the positive on the battery the pulse side glows, then cuts off. When running it will be off and then glow for about 4 seconds, then turn off, maybe 15 seconds later it will start to glow, then turn off.
I checked another cylinder and saw a rapid pulse like when a plug would fire.
Does this mean bad ECM? I wouldn't think a bad wire would do that.
have the same problem?
