I have an 89 3/4 ton w/302 She runs on spray in the throttle body and there's pressure on the fuel rail. Constant power on the injectors. But just won't run. Any suggestions.. Sat all summer (plow truck).

 

Gummed up injectors maybe? Possibly due to the reformulated gas sitting all summer.

 

Just checked with the right light and the injectors are'nt getting power.

 

is there spark? TFI module maybe?

 

yea theres spark in runs perfect on gas sprayed in the throttlebody. Pressure is good and just put in a new distributer module. still no power to injectors

 

all relays working fine?

 

If it runs on gas spayed in the throttle body then you've got spark and compression, you're just missing fuel. If I'm thinking of the right kind of EFI system then you should get quick pulses on your test light with it hooked up to one of the injector while it turns over. No light or a solid light are bad. Assuming you have no light, pull the codes. My guess is a sensor or electrical connection has gone bad. Good luck.
