Hey guys! Truck is refusing to build pressure at the fuel rail, it was sitting for years running when parked, drained all of the bad gas and put fresh gas in, drained from the schrader on the rail and figured I burnt out the old pump as it wouldn’t build pressure at the rail, installed a new pump today and another round of fresh gas to the empty tank, I can hear the pump prime upon start up, but presents me with a no start condition, if I spray starting fluid into the throttle body it will fire off.

from my understanding if the ASD was at fault I wouldn’t be getting spark?

Any ideas on what to look at?

 

Forgot to mention I did swap the fuel pump relay and ASD relay with new ones.

 

ASD feeds the fuel pump relay. I *think* there is a separate fuse for the fuel pump though, but, if it primes, then that ain't the problem.

If you jump the fuel pump relay, will it build pressure??
