Need help please, 92 Gt will not start

[JJCrosby6]

I have a 92 Mustang Gt and the thing will not start. I am getting good fuel pressure to the fuel rail and have replaced the fuel pump and Map sensor. After Replacing the MAP the car started once and ran fine, then died and will not start again. Has anyone had a similar problem? I would appreciate some help, i'm out of ideas.

Run codes.

Then go through the Cranks but No-Start checklist in the Useful Tech thread Sticky.

I went through the cranks but wont start checklist and everything i checked is functioning properly. Now the car will start after it has sit for a day, but will not restart. The pump is running continously and will not shutoff and i am getting a hissing sound from the fuel rail after it runs for about 4 secs. Any ideas? Thanks.

Are you running the checklist after the car will not restart?
If so, you should find the issue.

If not, you need to be make the car not start and then run the list.

Good luck.

You need to change your fuel pump relay located under the hood on the 92 cars.
