CHEVROLET LUMINA BODY PROBLEM

1990 Chevrolet Lumina • 13,500 miles

I have a 1990 Chevy Lumina 3.1.

A little history: It was my sister car. When she had it, it would run fine, except when she would take it on long rides for about an hour or so, and then it would shut down after coming to a stop. She took it to the shop and they replaced the air filter with the reasoning that the filter was so dirty, it couldn't get any air through, causing the car to over heat and cut off.

After that, she gave it to me. It seemed to run fine. I had a part time job, so I didn't have much money, so when I drove it around, the tank was always near empty. Then car started to act up again. It would die when I came to a stop light unless I kept my foot on the gas. And I noticed that sometimes it would kind of leap forward for 10 seconds as I was driving around 45 mph.

Then one one day, as I was pulling out of a driveway (inclined driveway) it just cut off. Usually I would be able to try to start it a few times, and it would work. But not this time. I had to get it towed home.

I got it home and replaced the fuel pump, fuel filter, and the Idle Air Control Valve. Nothing worked. I decided to take it to the shop, and they changed everything I chaged. They couldn't figure out what was wrong with it, said it could be ECU and charged me $450 to get it out.
And on top of that, some one stole the exhaust off of it while it was at the shop.

So, I finally get it home and noticed that one of the fuel injector fuses was out, so I replaced it, and got it to idle for 15 secs. But, as soon as I touch the gas, it dies.

Fast forward a few days later, and now I can't get it to start. It will turn over, but it won't start. And if it does start, it idles for 2 secs, then dies. If I spray some throttle body cleaner in the throttle body, it'll idle a little longer, but then dies.

Any suggestion? I also replaced the PCV hose and valve.

CHECK FUEL PRESSURE----WITH A GAUGE---WRITE DOWN THE NUMBERS........"YOU TUBE" IS MOST HELPFUL SOMETIMES IN SHOWING YOU HOW TO "REAL WORLD" DO SOME OF THESE TASKS

HAVING IT CODED MIGHT SHOW OTHER DISCREPANCIES......I'M GUESSING YOUR SYSTEM IS OBDI NOT OBD II

HERE'S SOME MORE INFO I GAVE ANOTHER FELLER, THAT MIGHT SORTA AID YOU ALSO
