Well I can rule out the crank shaft sensor and the spark plugs. :( I really thought it was the crank sensor but I should of listened. It was heartbreaking because the crank pulley was quite a pain. I could only find 3" bolts in town and it took forever. Anyway, I am going to get the cat. converter checked tomorrow and I think I will take the ICM in as well for testing. I know if I stick with it I will get there eventually.....

Remember, sputter is a weak spark. Inspect the spark plugs again. I had a cracked plug once, it looked like a small scratch.

DId you check your fuel pressure at the rail?

No I haven't checked the fuel pressure yet. How do I do that? Is there a guide for that one?

Also you may want to check you battery cables and engine grounds. You're engine grounds are going to be a wire bolted dierctly to the engine and going directly to the body of the car. I forget does the a 00+ bonnes have a voltmeter on the dash?

Yeah. It does have a voltmeter in the dash. It always runs a little high. Does that mean anything? Also I forgot to reset everything after I installed the crank sensor. I just did it and I am letting heat up again now. I was hoping maybe that would make a difference.

What'* a little high you should be running between 11.5 and 13.5 volts

The middle of the gauge is 14 and it is a little above that so I'm guessing 15. It has been a little high since I changed out the alternator about a year ago. Also, I just let it heat up again and now it won't even start when hot. Whatever it is, it is getting progressively worse. I don't have a pressure gauge but I think I can rent one from Autozone; or maybe I'll just make one. I'm starting to think its the fuel pump going bad. That would make sense right? What do you think?
