1992 300ci fuel problem
I have a 92 f-150 with a 300ci engine and it stalled tonight for no reason in the yard and will not start. I think it's a fuel problem because I checked for spark and I took a gas soaked rag and held it over the intake and she ran for about 5 sec. I can hear the fuel pump working and there is gas running out of the snifter valve on the fuel rail when I push it in. Anyone have any ideas. How much fuel pressure should it have and what would be the best way to test the fuel presssure regulator and would it even cause this problem. Any help would be great.

Check to make sure that the injectors are actuating. A noid light should tell you if power was being applied to the injectors.
I think that 45 psi fuel pressure is about normal. Other more knowledgable folk would know the exact number.
