Engine stalled while driving, checked fuel pressure, over 30 psi. Disconnected fuel pressure regular, gage didn't drop. Checked pvc hose, hose broken. Replaced hose didn't stop the stalling in gear. Need help.

what is the pressure specification for your car? they are specific and important to operation.

34 to 37 at start up and 30 while running


scan the computer for codes whether you have a check engine light or not. If you can eliminate fuel as a problem then its electrical. there should be some kind of code stored . It is obd1, so google the procedure for your car to read the codes. if no codes, test the fuel injectors. I had a similar problem with a chevy and we pulled our hair out because we couldn't find anything wrong. ended up being a couple of bad injectors.


A code check is a very good idea, but OBD 1 Fords are a bit of a pain to do. It is quite common on these for the ISC unit to just up and quit working, sometimes it is dirty and a good cleaning will fix them, but 8 out of 10 times you wind up replacing the unit. Check the throttle body also, make sure the butterfly valve is clean and operates properly.

Forgot to ask, does it die instantly when you put it in gear forward or reverse?



Then that sounds like the torque converter is locked up, there is a test for this but unless you know what you are doing I do not advise doing it, take it to your local tranny shop for a check out.
