1990 4by4 79,000 miles, b2600i
fuel injected manual tranny
Truck runs until warmed up then stalls, will not restart or will not start at all sometimes ....HELP!
this has been very frustrating, time consuming and expensive!

i have had my computer rebuilt, had a new fuel pump istalled, new rotor, plugs, wires and distributor cap.... drove it 3 miles, parked for 15 minutes and the truck would not restart,

i bought it this month and it has been nickle and diming me, dang, i want to like this truck,
but now it isn't trustworthy to even take for a short errand....I have owned a lot of trucks, this thing is impossible to diagnose.
any suggestions?

HELP!
anyone have any suggestions???

thanks so much for your help

Sounds like you're getting vapor lock somewhere in the fuel lines.

 

did you try the TPS (throttle position sensor) I am having a similiar problem and ruling it down to that.

 

check your gas cap.

 

I am having a similiar problem pull your feul pump relay and try to crank it over it should try to start once it does and stumbles and stallls replace the relay and it should fire up that is a temp fix, I am still trying to figure out how to fix this problem myself.
