Hey guys. Got a weird problem here
Truck will start as normal hot or cold run about 30-45 seconds and die. After it dies it take 10-15 pumps on the primer and it will start back up.
If I start it and bring the rpms up to 800-900 for a minute it stays running
I'm thinking low pressure fuel pump but not sure.
Truck runs normal and makes full power. No codes.
TIA
Maxxforce fuel issue, at 30-45 seconds running it dies.

Seems like fuel is leaking back/sucking air. Main culprit I’ve found is the line from the Davco to primer pump. Probably need a clear line installed to diagnose.
skallagrime and WMGUY Thank this. -
I appreciate your reply -
I guess so. Then something else will happen. Its all over the TTR. If you buy a Truck without warranty, over the milage/years, it really just one problem after another. Take it easy. Handle them as they occur, thats why they have mechanics and shops.
