ok yall in need of help was driving my 93 dully with a 5.9 turbo in it when she shut down the other morning she dident so much as fart at me i filled her up the night before drove for about 4 hours and parked her she was running fine started her up let her warm up for about 10 min or so prob should have waited longer but she was driveing fine when i leaned into the gas a bit she started to pick up speed and then just shut down no sighn of any thing she still turns over and the on board is not saying a thing just 12 and 55 from what i am told is hi and bye cracked the most forward fuel line and there is fuel sitin on the injector i have no idea at what could be the matter with her if yall could give me some ideas of things to check and on some accounts on how to check them i would be very thankful to each and every person even the smallest thing might help me right now thanks
oh and this seems like a killer site so far wish i would have found it years ago

 

sounds like maybe a shutoff solenoid, not sure where they are on the 1st gen. trucks, or could possibly be lift pump related, check in the 1st. gen. forum & see what you can find on a shutoff solenoid, I'd try that first, sorry I couldn't be of more help, Dusty

 

There is a fuel shutoff solenoid on the first gens. If you remove the plunger fuel will go through withought 12 volts of power. You should first verify 12 volts to the solenoid. Then pull the plunger and see if fuel is getting through. Without the solenoid you won't be able to shut it off with the key. You'll have to use the manual shutoff lever. If you still aren't getting fuel check pressure from the lift pump. If you are getting fuel from the LP you are in need of a new injector pump.

 

how do i test the lp only thing i can think of is to crack a line and try to start not trying to be dumb but not trying to kill my truck for good ya know

 

i cracked the lp and got fuel cracked the first injector fuel is spiting out in spurts what else could be the deal i am thinking cps or puter let me know if it could still be the fuel system right now i think this is a good thing right

 

You should repost this in the 1st gen section. You'll get replies faster. The fuel coming out on the injectror side should be under high pressure not just a squirt. The guys in 1st gen can help you better than here.

 

One more thing.... change your fuel filter.

 

A fuel filter could be the issue but the first thing that I'd check is the electrical connection to fuel solonoid. Easiest check is to run a hotwire from the battery to the solonoid terminal (found on top of the pump on the end furthest away from the timing gear. On mine there are 2 spade terminals facing 90* from each other. Either one will work.) You should hear the solonoid click when you jumper it to the battery. If it clicks, see if it will start. You'll have to pull the jumper wire or use the manual shut-down lever to kill it so be prepared. If the solonoid doesn't click or it still won't start, removing the plunger under the solonoid would be a good next step. Keep us posted and keep asking questions. Usually these things are pretty straight-forward.

 

well i dont know witch one it was but she is running so thank you to all for your help
