Car wont start

Did you check primary voltage at the ignition coil? Pink wire, goes hot with the key on, any voltage there? That voltage comes from ecm 1 fuse.


I haven't looked for info on your instrument cluster, yet.

The first part is magic, (EFI system and good engine)
but?????
gauges go off can be a bad fuse or loose fuse to cluster.
when any Gas engine stalls. the RPM drops to 0
the EFI sees that and goes to key on, not started self test.
this is covered in the operator guide.
key light comes on KEY LIGHT, HUMMMMMMM
Let me look at the waring lamps, there are many.
one light is engine overheat that is logo of a thermometer but looks
just like a key.

is this a engine stall post
or engine runs perfect all the time , but only my dash acts funny
you didnt say?

key lamp?
immoblilzer (big trouble there)

a stall is anytime engine RPM drops to zero. called a STALL.
if your cars engine stalls, post that way, the lamps are all normal
on at any stall, on any car.
at a stall , rpm goes to zero and MPH drops to zero as you coast to a stop , stalled. that is all normal for any stall.

if engine stalls.
that is complex.
here is list.

1. lost 12vdc power to EFI system. (battery died, fuse blown)
2. never gave your car the 60,000 mile tune up, see opr, guide.
3. bad fuel.
4. overheated the engine.
5. engine oil gone, never ever checked at each fill up.
6. other more complex EFI system parts failures, ASK.

have you checked the fuel pressure. maybe a clogged fuel filter or a bad fuel pump

The light you see is a security light. Usually it shows up when the security system is armed. If the light stays on then I would suggest getting in the car and closing all of the doors. Then press the lock button on the key fob. Then unlock the car with the key fob and it should go away. Try starting the car afterwards to see if the light goes away if it doesn't when you unlock the car with the key fob.

The first thing you need to know is what the alternator output is when this starts happening.
It could be a faulty connection in the wiring harness, or a bad ground connection, or a failing alternator.

I would ask the Pontiac mechanic and see what he recommend. They wont charge you nothing for that. If you don't get the right answer go to another garage and ask them.

have you checked your timing?sometimes it jumps.

If you look down where the starter is you will see al little round selinoid with to things sticking out that look like screws and have nuts and wires going to them. Take a good gauge wire and jump across them. If the starter does not kick in or spin over then your starter is bad. If it does kick over then there is a good chance that the ignition switch has gone bad.

Go to the fuse box and change the fuse for "Gauges". I think this might solve the problem.

With the ac, sounds like you definitely have a short with the ac electrical wires. Have a mechanic check that out. 2. The wiring for the dashboard gauges may have tears or something is causing high resistance in them or you may need a new dashboard itself. Have that checked too.

As far as the brakes when you trying to change gears, what do you mean brake lock wont open? Finally with the RPM, I dont think your dashboard gauge is working correctly so you may need that replaced also.
