None of the fuses are dead, and it's been like this for over a week now.

The module on the cap carrier on the top of the motor is a common failure. I suggest replace plugs, boots, coils, carrier and module. Cross arcing in the carrier is usually the reason for the failure.

I've had the module checked 6 different times already, and every auto parts store that has checked it has said that the module is fine.

My car gets harder to start the colder the weather gets. It seems to flood easily, and usually takes many tries to finally get it going. I recently replaced the coil pack with one from a junkyard to save money. Could this be the problem. It starts ok when its warm.

I always have new plugs installed or clean the 1's already in if recent(1yr) before really cold weather. Iridium or platinum seem to work best also. Coil pack should not be issue if works fine in warm weather.

And check fuse 37 as this has been reported to cause no/hard cold starts if blown.

And why do you think it is flooded? You can clear flood by holding pedal to floor usually.

Engine Mechanical problem
1995 Pontiac Grand Am 4 cyl Front Wheel Drive Automatic

I had the car put on a diagnostics machine and it said running to lean in bank 1. What would be the cause and what do I need to do to repair?

Usually that indicates a bad o2 sensor. On your vehicle it is located :Under hood, center, rear engine area, passenger side of distributor, mounted in block.

I can drive the car till it reaches operating temperature, then it will just die. Won't start but turns over. The fuel pump sounds like it is working. I changed the coil housing, ngk plugs, boots look good, coils measure 6K ohms, after the car cools back down it starts fine. Ideas?

Is there spark when the engine is up to temperature? If not, test the Ignition Control Module when the engine is up to temp. Also, it could be the coolant sensor. It is easier to just replace this sensor than to test it.

It definitely sounds like a sensor problem!
I have the same car, IF the car can drive a little I would recommend going to autozone.

To make sure you can ask them to check out your car for free, they will hook an electronic that will pinpoint exactly what is wrong.

Autozones' computer scanners will tell you what trouble code is stored - it will not pin point the problem, but it will point you down the right path. BUT - there is no mention of the check engine light being 'on' - so that means that there is no trouble code stored in the computer. If the check engine light is 'on' then have the computer scanned and post back with the trouble code.

That is correct, the check engine light has never came on when it's shut down on me. The last time it acted up I disconnected the battery cable to see if that would reset a bad sensor or module, no luck. I do have an Autozone close by, would be interesting to see if their scanner could detect the problem being there are no codes being tripped. I think I will replace the coolant sensor and coolant sending unit and see what that does. I will let you guys know what I find out!

If the light is not on, then autozones' scanner cannot help you. When the engine stalls again, remove the ignition control module and have it tested at autozone - it will be hot so be carefull. Changing the coolant sensors is also a good idea.

So I changed out the coolent sensor and the sending unit sensor but it is still acting up. It did run longer but eventially shut itself off. Next stop ignition module.

It ended up being the crank sensor. That was fun to replace, they usually break off in the block. Four hours later I invented a tool to get it out of there!
