I just bought a 04 FX4 with a 5.4 with a 135,000 that had a couple issues. Well i had it running, not great, but ran. I changed out the original plugs and coil packs, packs came with the truck should have been a flag but, now it wont start. Checked spark with a old plug and coil has spark on 1 cyl. Checked fuel pressure after the filter had 45+ psi. Hooked filter back up still not starting. Went to check fuel pressure and found no pressure at filter which i had when i had the gauge hooked up. Could it be the FPDM or the regulator?

 

Welcome to the forum, hope you get your truck running soon.

Welcome to the F-150 forum! Glad to have you join us.

Have any fun performance modifications planned for the truck?

 

Ok finally got the FPDM installed now its flooding cylinders with gas. if i un-plug all the injectors i can get to want to start. Every once and while it will back fire through the intake. any suggestions on what i should look at next?
