I have a 1991 chevy lumina that will start and run for 15 minutes and then die all of a sudden any ideas?

Question

it is a v6 3.1 Chevy lumina and i have put a new computer, coil pack, and temperature sensor on the car. it does not change anything the car will also not start until it cools down all the way. i have ran a computer scanner on it and there aren't any codes

this engine doesnt have a spider valve

Answer 1

the odds are the control module is shot..thats why as soon as the car gets hot it quits...run the car until its die out and have the module tested by your local autozone or whatever you have around you...if they say it passes the first time, have them keep testing it until the module get very hot, you can feel it, it gets very hot even while testing..the module is located under your 3 coil packs.

Answer 2

sounds like a clogged catalytic converter.
start the car and after about 10-12 minutes look under the car and look at the exsuast pipes. if it is red hot change the catalytic converter

Answer 3

Sometimes a clogged fuel filter will cause this problem. The sediments clog the filter under pressure then settle back down after sitting.

Answer 4

One change the fuel filter, then a question does the temperature rise up all the way? If so change the thermostat.

Answer 5

I hate to say it but get rid of it. My wife had a Cutlass Ciera, and for the most part it did the same thing. After dumping all kinds of money into it we finally traded it in as quick as we could.

Answer 6

I answered this earlier and you removed the question........?
Once again,it sounds like the spider valve in the fuel injection system.

Answer 7

the first thought that came to my mind upon reading this post was 1. WHY is college tuition fee is America ridiculously expensive? WHY do colleges need so much money? A college is NOT a company like Apple or Microsoft. My sister will graduate from her 4 years of university soon and the total coast of tuition pee paid during those 4 years....is OMG too much. the amount is almost as much as the U.S. national debt. 2. do colleges REALLY need a lot of money? 3. America is currently facing an economic crisis; it is predicted to be one of the worst ever in U.S. history. So unemployment is a rising issue, the economy is getting spoiled and there are more innocent citizens suffering beneath the poverty line. And i am NOT against the government but the federal government doesn't seem to be sorting it out well. I don't know that much about the ecnonomy, so I learned from my sister (she's a business / economics major) and i can tell that the nation, the economy and so on are all facing a crisis. Soo....i don't know but unless the government promises to like help the poor pay for college or something I strongly suggest that colleges DO NOT raise tuition fees. Otherwise...America will face an even worse educational crisis. Does the stuff I typed make sense? hope it does. And......the good news is that the expensive tuition fee paid to a great college was actually worth it since my sister got a great job 2 weeks before graduation.
