If my T-Bird sits for more than 2-3 hours it cranks but won't start.

Sorry it took so long to get back to you. I was down sick for awhile,then my computer went down. So here is what I got for fuel pressure readings, 35 psi as soon as the key is turned on but the pump keeps running as if it filling up the fuel line. I cannot get a running pressure because a few days ago the car quit running while I was driving it and wouldnot restart. I found that the hot wire from the battery had rubbed a bare spot on it and shorted against the frame. I replaced the cable but the car will only start and run for about 30 seconds or so,then it dies and will not restart unless it sits for a day or so. I sounds like it is running rich so I checked the plugs and they smelled like they were gas fouled. Any ideas on what happened. Thanks for your time I really appreciate your help. bobthemechanic49@yahoo.com

Bob, Possible faulty engine coolant temp sensor, - or - Sounds like one or more fuel injectors are leaking, I do not know how you are equipped with tools, so I recommend removing the fuel rail and operate the key with the rail connected to fuel lines & injectors in the rail, you should be able to identify the faulty injector(s)
