Help! Truck wont start

[Dylan Srawley]

Tested compression, also getting spark and fuel. Changed o rings on injectors, checked all grounds, asd relay . Sometimes truck will start and die after about 10 seconds .
Any tips or ideas ??

when it starts for that few seconds, can you open the throttle a bit and keep it going?

 

[Dylan Srawley]

No. It just does either way. I even changed the tps off a parts truck I have and no luck

Say you're getting fuel but how much? What's your fuel pressure?

It has a new fuel pump. 48 psi
