my buddy has a 95 12 valve that wont even try to start. he started it one mornin to let it warm up and it just cut off. just turns and turns. put new lift pump on and still nuttin. any thing else we can check?

 

Sounds like the shutdown solenoid is not working. Have someone pull straight up on the solenoid and someone else try to start the engine. The solenoid is on the driverside of the engine on the side of the injection pump. It is the thing with the rubber boot on the bottom. If it starts by pulling it up by hand then you need either a new relay or the fussable link that sends power to the solenoid. Go to www.fostertruck.com for more info and the correct parts.

 

the guy he bought it from alredy fixed that and put a pull cable on it.

 

then I would check the cable and make sure it is pulling all the way up on the linkage.

 

Did he bleed the air from the lift pump when he changed it. He would need to crack the injectors too if he cranked it over without bleeding the air from the pump.

 

alrite we will check that tomorow. anything else we can check before we have to haul it off to the shop tomorow?

 

Push the the primer several times on the LP...

 

we cracked the lines but how do u get air out the lp ? i primed it like crazy also. im apreciatin all ur inputs to. thanks

 

on top of the fuel filter there is a nut with a smaller nut on top of it. That is the air bleed vent. Crack the smaller nut open about 1/2 of a turn then pump the lift pump until just fuel comes out of the vent. Close the vent and give the pump a few more pumps. There will still be air in the line to the injection pump. You can bleed that by cracking a fitting by the pump. You should be able to get the truck to start now but it will die several times and run rough until the air is all gone.
