jus rebuilt my front end on my 90 22re auto. the vehicle starts and sounds strong then after about five or ten seconds shuts off.. thats pretty much it, i am looking through the vacuum lines for cracks to repair. also currently looking my hose diagram for mistakes let me know if there ,is something you think i may be missing, thank you..

 

Sounds like only cold start injector is squirting; check ground the attaches to intake. Mount is rear pair of intake runners where the upper and lower intake is bolted together on under side of mounting flange.

 

If you searched for "starts but shuts off in 10 seconds" you would have gotten about 40 postings with your exact same problem. So, think about using Search.

Your problem is almost certainly in the VAF-COR circuit. It's the easiest thing on the whole truck to diagnose. Jumper FP to B+ on the diagnostic connector; that forces the fuel pump to run with key-on. Does it start and run okay now? You've found the location of the problem.

 

mine did that after i did a complete rebuild. turned out to be the cold start injector wasn't sealed well on the plenum. took a smoke machine to find the leak
