my 94 did this yester day. it fired shut off. i restarted and it started up just fine and ran normal. then last night i went to start again and it wouldnt. after a few tries and putting fuel in the tank it started and ran fine. this morning it wont run. it starts and dies immedietly. it runs and sounds good for about one second and then dies. any ideas? i know it has fuel in the tank. i wish i had a fuel pressure gauge right now! i have been holding off on that! help! and thanks

 

You shouldn't need a fuel pressure guage. Your LP is pretty much bullet proof. Next time it quits leave the key where it is and go out to check the plunger on the shut-down solenoid. If it is down then I think you should look at the shut-down relay on the firewall. Try swapping relays and see what happen.

thanks for the info tom. where is the shut down solenoid? and where on the firewall is the relay. i am a n00b with this truck. thanks.

 

 

It is the round thing that is straight ahead and below the brake fluid reservior. Has the wire w/ a blue split loom on it.

 

whats ur idle at? could be a really low idle...when i bought my truck from the previous owner it was at 500rpms and i had to hold the throttle for 20 sec to keep it from dying...and when i hit reversed before it was warm it would croak...so maybe ur idle is low should be at approx 800

 

or when u turn the key to the on position before u start her get out ur truck and check if that chut off solenoid is fully up....and then start it and check it again if it wont go any higher while its runnin then thats not it

 

fuelfilter solved the problem, thanks

 

nice......that reminds me mine's overdue for a change
