So I just picked up this truck and can't get it running on its own got injector pulse 35 to 40 psi of fuel pressure have spark. It'll run as long as you force feed it. What are your thoughts on what I should chase

 

Well it ain't spark, it's fuel delivery.

 

Just because the injectors are pulsing and there is pressure does not mean it is spraying fuel. I found most of the injectors on the Bronco II were clogged from the truck sitting so long.

 

True story, sounds like a bench test for injector squirt
Could try a injector clean using the pro stuff through the rail

 

Gunna pull the upper intake off this weekend and try and clean the injectors. Thanks for the the replies I'll let you know what happens

 

Just tried to start my truck with gas pedal to the floor. Truck didn't crank right up but, it cranked up a whole heck of a lot faster than normal off the gas pedal crank up after sitting a while...any help greatly appreciated.....

 

Not sure why you jumped in on this thread from last summer but having the pedal to the floor on startup turns off the injectors.
