Car Not Starting? (1993 Bonneville SSE)
My car was running fine with no problems at all. I drove it the night before and it was fine. The next night I went to get in it to go get some gas. When I went to start it the engine wanted to start but wouldn't turn over all the way. There is full power so it'* nothing to do with the battery. I just installed new spark plugs and wires anout a week prior. I took the alternator off and had it tested and it was fine. What could it be? I also ran a simple diagnostic on it and it gave me a code 53 which is EGR problem or ECM over voltage. I've had this code since I got the car so obviously it'* not the problem. It'* getting spark and seems to be getting gas but the engine won't fire all the way. Any suggestions on what it could be before I take it to the shop to get bent over.

I forgot to mention other things that may help too. I replaced the fuel filter a few months back. Also when I drive the engine stumbles on acceleration at about 2 RPMs then straightens out after. If I slow down alittle and begin to give it more gas it will begin to stumble again. I thought it was the fuel filter at first. I changed that and it didn't fix it. Next I changed the wires and plugs and it still didn't fix it. I don't know if this problem has to do with the starting problem but I figured I'd throw this in the mix. These dam cars are a pain in the *** with all the electric **** they have. If anybody could help I would appreciate it alot. I would like to know what'* going on just in case I could fix it myself.
Things that I can think of so far:
Starting Problems:
Fuel Pump
Fuel Injector Adjustment
Bad Coil(*)
Stumble On Acceleration:
Timing
Transmission Problems
EGR Problem
Vacuum Leak
Any other suggestions?

Let'* clarify what you've posted already.
The engine does or does not turn over with the starter? You mention it wants to but won't (Check battery cables at both ends for any corrosion, possible you have full power, but can't get enough to the starter)
Shouldn't be plugs or wires or alternator if it ran 100% just before this happened.
Check the resistance on the coils per the techinfo article. Start with the posts, if you get odd readings pull them and check the primaries.
Take the connector off the ICM and look for any corrosion or issues...ensure everything is making good contact and reinstall. (sometimes taking off and putting a connector back on 5 or so times does the trick to clean up contacts)
Most of the info I got was because you mention a stumbling. It could also be fuel pressure related as well. A fuel pressure gauge hooks up to the valve on the fuel rail to give you the reading.

Ok I should check the fuel pressure, the coils, and the ICM. I don't have a fuel pressure guage but I can pull coils and ICM and have it tested. Those are pretty simple tasks. I'm trying to fix it myself because I don't feel like paying $300 for some jack *** to do something that easy when I can do it. If I can't do it then I don't have a choice. Thanks for the replies though. Oh! if the fuel pressure is low what can I do to fix this? shop material or easy fix?

If the fuel pressure is super low..then you'd need to replace fuel filter, fuel pump, strainer sock. If the fuel filter isn't plugged up..it'* an ugly one.

Today I had the ICM checked and it was fine. I bought 3 new coils and installed them. Nothing happend. So it'* nothing to do with spark or ignition. The only thing I can think of is maybe the fuel pump. I guess it'* to the shop for a raping.

I don't think so. I'm getting it towed to the shop up the street. They can figure it out. I already done what I could. If it'* the fuel pump then it'* going to run me about $300 total they said. Luckily it'* tax season and I have the extra cash.
