Yeah it just dies out of the blue and then won't crank back unless I spray starter fluid in the intake. And even now I can't drive it bc it doesn't stay cranked but for about 2 seconds. The only time it stays cranked longer is if I keep my foot on the accelerator. And if its a sensor wouldn't it be throwing a code?

Once again... Diagnose the CPI INJECTOR LEAK

THE FUEL SYSTEM HAS NO SENSORS. So a runability issue with no codes is most def fuel related

Well replaced fuel pump last night and still nothing! So every part of the fuel system has been replaced and still nothing is working. I don't know where to go or what to look at. Could it be a ICM, crank sensor, or the pick up coil?

Nope, all those would trigger codes. Its fuel related.

I want you to jiggle around the red/blue wires that come out of a gromet in the lower intake, under the throttlebody. Those power the injection unit and have wires in the connector thin as hairs. The rubber insert in the plug that is inside the connectoe itself is a known problem after 20+ years. Mess around tugging and pushing thoae wires and see if you get any difference... You are gonna kick yourself if this is your issue, its an 8 dollar part!

And for gods sake stop wasting your money throwing parts at the car.

If you really want to spend money wisely, get yourself one of these... This will show you a leak for sure.

And this is how it is used.
