Asked by GuruD7164 Sep 26, 2017 at 09:51 PM about the 2007 Ford F-150 XLT SuperCab

Question type: Maintenance & Repair

sometimes my truck starts first try. Other times it cranks but won't start. it's
not the fuel pump. it's not the fuel pump module. both have been replaced.
you never know when the problem will happen. Seems to be getting
worse.Very intermittent. any suggestions on what the problem could be. My
mechanic is stumped and his approach seems to be keep replacing good
parts with new parts.

Have you tested the resistance of your starter and fuel pump relays?

    I have a 2000 Ford F150 I've replaced the starter, solenoid, battery terminal wire, and had the battery tested. The truck still won't start it just clicks. I can't figure out why.
