Problem solved. Opti-spark/ WP---car starts runs for a few seconds then shuts off?
Need some help from the guru's on here. My 95 Z (53,000 miles) other than Moroso CAI it has no mods. I've only owned it six weeks.
Now the problem. Initially after buying it the car ran fine then I went on a 125 mile trip and upon arriving at my destination the car shut off after making a stop at a traffic light. It started right up and went about 100 yards then shut off again. This time it started and ran until I got where I was going. (about a mile)
then the rest of the weekend it was fine. A week later (again in the middle of a long trip) it just shut off going down the highway, cruising at 65. Started back up stumbled and shut off again. started up and ran until I got home. This time I changed the "computer" with one I had in another 95 Z and it ran fine for another week or two. This past weekend it finally shut off and will not run for more than a minute without shutting off.
It's kind of weird. We checked the fuel pressure and it's at 39. You can spray starting fluid in the TB and it runs until the starting fluid runs out. still shows 39 PSI on the fuel pump pressure.
Any ideas out there? I've heard Opti spark, fuel pump computer and security system.

I've heard ICM but I just didn't think it would have to heat up to be bad. I'll have it tested in the morning.
