Hi there it sound like you have a wire bridging giving the ignition system a live supply you will need to look closely at all the wires that move when you shake them for a brake or broken plastic over and repair this

hope this helps regards JR

1997 Pontiac Sunfire 2.4 DOHC, 2 outside cylinders won't fire


One coil serves those two cylinders (no. 1 and 4), so try repllacing that coil.

I have a 1997 pontiac sun fire its getting fuel and spark its passing all the codes and the theft light is on its not starting at all it wants too just wont i changed cam sensior


Leave the key in the ignition and in the run position for 20 minutes, this should relearn the antitheft system. If that doesn't work there are bigger problems.

Engine quit running has no spark at plugs


Have the coil pack checked out. Plugs don't fire if the coil pack is bad.

I would check the codes first, with OBDII systems the codes will give you a good idea of what my be doing it, the ETS off is your Electronic Traction-control System, either you have the emergency brake pulled up or it is a seperate issue,

things that may cause your symptoms are,
bad fuel pump-check fuel pressure,
bad MAPS-running the codes should show you if it is but you can also do a diagnostic test
misfire-same as the MAPS, codes will let you know which cylinder then it would be a matter of replacing spark plug and wire(I can't stress enough on getting high quality plugs and wires), if that does not fix the misfire then a compression test is in order
bad coil pack(s)-misfires on two cylinders that are on the same pack, sorry but I do not remember which cylinders are fired by which pack but if you follow the plug wires over to the pack you will see,
vacuum leak-hard to identify but may also have something to do with your ETS light, check the booster vacuum hose for cracks
bad IAC-again the codes should tell you but they may not,


there is the points that I would start off with, I hope that I have been helpful
