Yeeeeeaaars ago i had this problem where my 97 would start and die immediately. To make a long story short and because I neither remember nor understand the details, someone on another forum thought it had lost a software ground. He had me try cutting a wire on a harness under the dash, over the brake pedal area, and run it directly to ground with a cheapie toggle switch. Bingo. I've been driving it that way for many years.

The only drawback is the fuel pump will run when it shouldn't, but that's what the toggle is for. I have never actually used it though and its worked great for at least 10 years and i haven't killed the fuel pump yet.

This was meant to be a temporary fix but since it works I've never pursued a permanent fix, or seen a need to.
