You are mistaken. The Theft deterrent system has nothing to do with the fuel pump. If the correct password is not received by the PCM, it will shut off the fuel injectors.

Fuel injectors, fuel pump, does it really make any difference? Same result. I guess I should have said fuel stops going to cylinders. Good grief!

People like lucky, abrasive as they may be, are the reason this forum is still a decent source of information. A bunch of people blurting out "close enough" info with no moderation is a recipe for a forum that is totally useless.
Why do you think people post questions that are so common? Because searching for things results in hundreds of posts with people saying things that dont quite correlate with one another. EXACT information is never a bad thing here.

Please don't chastise him for correcting you. This forum is plagued with so much misinformation. It is a real problem, and joe blow searching for answers a couple years from now could be led down the wrong path if people don't take the time to clear up incorrect statements when they see them.

I see your point. But if every time you don't use the exact correct word someone jumps on it that's a little crazy. And for what its worth I've seen Luck make mistakes himself but I didn't feel compelled to jump on it. Can you imagine if we all did that? Its a forum. Let people speak. Go with the flow. If someone gives incorrect info others should be able to sift through it and find the correct info they need
Also, for what it's worth, Lucky did not "jump on it". He simply corrected your misinformation. No all caps shouting, no bold letters, no insults. Just the facts. That's far from impolite if you ask me.

This forum is full of misinformation because of people like you. People that do not want to be held accountable. People that provide wrong info, and leave some poor bastard chasing his tale, when he has a problem with his car. To top it off, when the wrong information is given, you have the unmitigated gall, to get pissed ...when someone corrects you. Dumb.
And for the record if I do post something that is wrong(or inaccurate), I hope like hell someone corrects me. And when that happens, all you'll get from me is thanks, and complete embarrasment that I could have been soo careless.
I hope the mothership picks me up soon.

FWIW: Shortly after I got my car I started experiencing what sounded exactly like the column lock issue which has similar symptoms to yours. I don't remember if it threw codes or what they may have been. Turned out it was the steering wheel lock tumblers not fully releasing or engaging and the system not knowing how to deal with it so it cut off the gas. No new ignition switch installed by the dealer of the column lock fix solved the problem. Fortunately, after/because I was raped by a dealer (got the money back) the GM Area Service Rep covered the repairs even though the car was years out of warranty.

Same problem. Fuse 25 worked
Absolutely frustrated and fed up with this car and it wouldn't start last night I tried till I was blue in the face . thought about disconnecting the battery . I was in an absolute black night, luckily I had a friend and was able to get a ride home. Watch YouTube videos all night about bats and keys and resistors and bull crap. Came back to the car this morning. Did more Google searches and came across this thread. I pulled fuse 25 waited one minute stuck it back in and the car fired right up. Thanks for the tip. Thanks for your help guys. Good luck to the rest of you poor guys that are having the same problem. I'm sure I'm going to have the same problem again one day. ABS and traction control and having more horsepower than cubic inches is all a lot of fun. But I missed a good old days when you could just grab a jumper lead and start the car with a screwdriver in case of emergency

Why laughing?
Are you laughing cuz I'm responding to an old thread? Or because I've had this same problem that apparently so many other C5 owners have had? ..... Ultimately that worked for about 2 days and I have the same problem again. Pulling fuse 25 and duplicating the artificial repair didn't work anymore. I found it the two white wires coming out of the ignition tumbler were loose and then if I rattle them I could occasionally get the car to start for a second. Looking at them further I realized I had just ripped one of them out. So I took my spare key strip the wires taped them to the resistor in the key and it started up and drove home. Worked for a day, and now the same problem again. It has fuel pressure. But that doesn't mean that the fuel injectors are pulsing as they're supposed to. I haven't figured out yet if it's cutting the spark or cutting the injectors. Does anybody know?

I'm chill.
It's all good. Thanks for the help and advise. I have never started a new thread, but I'm sure I could figure one out. I've just been doing research on my issue and so often my search leads my to this forum. I figure if I am reading it, other people are too. So I've developed the bad habit of replying to old threads.
I hope I didn't offend anyone. I sure did not intend to do that. Thanks.

I am having the exact same problem. The car will fire up immediately and then die just as fast as it started. Once in a awhile it will actually remain running, but it usually takes between 6-10 tries. After several starting attempts I will usually smell gas, but can't find any leaks, loose fuel lines, etc.... I don't have any codes and am still looking for the answer to this problem as well. I will try my spare key and see what happens.
