1991 Chrysler New Yorker won't stay running

Starts up cold. Runs for 10-25 minutes then just shuts down. Sometimes it will restart for about 5 or so minutes. Then has no fire at spark plugs, The engine is not overheated.

Changed the fuel pump, cam sensor , coil pack , spark plugs , heat sensor , crank shaft sensor , purge solenoid, replaced smec.

Still will not stay running. Any suggestions?

Blow it up...lol.

I am having the same problem with mine. It used to only act up when it rained, but this past week it has been coughing and sounding like a dry heave. I go to give it gas and it won't go. If I pull to the side of the road and let it sit for a while, that seemed to work last week.

Unfortunately, it wouldn't start yesterday at all. So it sits infront of my house. I don't get paid until this friday so it's gonna stay there.
I have replaced the fuel filter, the plugs, and the wires. It only ran worse. You said you replaced pretty much everything my friends are telling me to replace. If your's isn't working by doing all that. I'm not gonna spend anymore money on mine. I only paid $850 for it almost two years ago and have spend almost the same amount in repairs.

Im having the same prob with my 90 dynasty, just wondering if u found out the problem, i was going to change the coilpack also but iseen it didnt work 4 u. My friend said it might be the cooling sensor???

I replaced the fuel tank in June. Somehow there is a small hole in the fuel line now. The mechanic moved and closed up shop before he could fix it. Now the suspension is shot...I got a new suspension system put in it back in April..so I thought. Now it won't go up a steep hill unless I am going 50 miles at the start of it. It's falling apart. I don't have the $400+ to fix the current repairs. I'm trying to get rid of it. Someone put it in the demo.

well spent 100 bucks on a coil pack because there was no spark when it didnt start, guess what happened ...? it didnt start of coarse when I cahnged it so scatch that off the list. My boss told me its prob the crank sensor????? no clue

should of responed before, but if u havent figured out the problem its prob the cam sensor I changed it on mine and its runs fine now

check leads too coil pack.use dielectrical grease,check idle speed motor,check fuel line presure 40lbs,50llbs with vaccum off regulator,and check return line pressure,check for faulty ign. switch,check ign relay under hood. do you have a command start? if so get rid of it!
