Hello I own a 1987 chevy celebrity 4 door it was my grandmothers car and she gave it to me before she passed away it had 54 thousand original miles and she was the sole owner it had an A title
anyway I've been driving it for the last year and a half with only normal wear n tear problems but just this winter its started stalling once and a while and It would normally restart np till yesterday it was a really cold day but I was sitting parked running and it just died and would not start I could dump fuel down the throttle body and it would fire up for a minute and then die again so I was getting it towed home with my cousins truck using a chain and I decided to try to start it as we were goin down the road and whatta ya know it started sputtered a bit but then ran fine. I drove it all the rest of that day with no prob's that night I started it when it was really cold again and it ran for about 5-10 minutes warming up and it just died again and its been a couple day's and will not start HELP! Whatta ya think it is?

You need to do a fuel pressure test.
Your system needs around 15 psi for the injector

if you have the correct fuel pressure the next thing to test is that the injector is getting a signal.
You can buy a tool called a "noid light" that you plug into the pigtail after you unplug it from the injector.

If that's good then the problem has to be in your injector or the pressure regulator built into the throttle body.

Good luck
