I have a 4.6 heritage and i just replaced the starter. Now it rolls over but not starting. Any suggestions for troubleshooting? Lights come on but im guessing its fuel or spark related.

Is the battery and cables/terminals in good shape?
how many miles on truck?
Have you changed plugs/cops recently?
FPDM?

Cables and everything look good and as clean as u can keep them for a 4x4 lol. But i did replace the plugs and rebore some of them after i blew them about 9 months ago.

Im also at about 138,000 miles.

Im not quite sure what fpdm means... Im not vehicle savvy. I kniw enough to change parts that need to be changed and enough to keep a vehicle running and a little more.

Fuel Pump Driver Module
Mounted on the frame above the spare tire (gotta drop spare). Common issue is the thing corroding and allowing moisture to get in, messing it up

Any way to check fuel pressure on my truck before i go replacing parts? I already replaced the starter because it wasnt rolling over but after i replaced it, it would start and roll over but this morning it wouldnt start. Just rolledover and didnt attempt to start

The module is an easy check, if it's still in one piece and not corroded, it should be fine. If you inspect and see exposed circuitry, it could be the reasoning as to why your truck won't start. I think it's like 50 bucks if it's bad. One of those piece of mind parts to check.

May have just corrected myself. Your Heritage is the previous generation body style right? If so, no FPDM. My bad, one of those afterthoughts lol
Maybe someone with a little more experience with that style truck can chime in with some ideas

Thanks Scorge. It is a weird truck. But its based off of a later model. Should i check the fuel pump and filter?
