asens

Finally got it worked out...I tried getting the truck started by running batt power straight to the lp, this is when I found out I didn't have any activity at my injection pump either....ended up being the crank shaft position sensor. The truck didn't know it was cranking.....About a month ago I got a p code that the sensor was out so I replaced it. This time it didn't throw any codes when it went out.......Thanks everyone for the help

Ground looks fine, I traced the ground wire into the bundle of wires and it looked fine as far as I can see.... hmm still searching...gotta love elect. problems

I checked the codes I get P0645 which I believe is unrelated...I checked the ohms at the pump, it read 2 ohms, so I might have a problem there.....Checking the ground will be a good idea, I replaced the crankshaft position sensor 1 month ago, maybe I tweaked the ground...... thanks for the help I'll check on that now......gotta love these nice alaskan days with no garage....

Thanks for the diagram, I had been looking for that information.....just in the wrong places......thanks

So that would point to a problem with my ecm? Do you think its something that could be flashed.......

the 8 volts stay constant when turning the key on or bumping the starter

I have the stock lift pump mounted to the block. The lift pump will only run for about 1/2 sec. when the key is turn on, when I bump the starter the lp won't run, I tested the voltage at the plug to the lift pump, reads 8 volts.Anybody have any ideas? thanks for the help....
