I recently bought a 7.3 idi engine with a 5 speed bolted to it for 300$. All I wanted was the transmission, but the guy didn't want to sell it seperately and this price was already a steal for the transmission, flywheel, clutch, and slave cylinder. So needless to say I bought the engine too. It has a ford reman sticker on the side of the engine so it may not have many miles on it. I am trying to get the engine running and check the condition of it so I can sell it. I have two of these diesel trucks
and a spare motor would be nice, but I need cash and room in my shop more than a spare motor.
This is what the engine is doing:
Engine spins over, gets fuel to all 8 injectors. Engine starts and dies almost immediately. If you hold the throttle open it will run for a little longer.(maybe a maximum of 2 seconds)
This is how the engine is set up (this is probably where the problem is):
1.)The fuel filter base has been removed. 2.) The supply tube going to the center of the back of the injection pump has been cut and has a rubber hose clamped to it going to a fuel can. 3.) The fuel lift pump has been eliminated(no fuel lines going through it) 4.) The return line on the right side of the engine(passenger side if it was in truck) has a screw in it so it will not leak. 5.) The return lines on the back of the motor are connected with a "t" and have another hose going into the fuel can.
I have the positive cable on the starter going to batter positive post. The negative cable on the starter going to batter negative post. There are two terminals on top of the injection pump. I was not sure which was the shutoff and they both clicked with a jumper wire from battery positive, so I connected a jumper wire to both of them coming from the batter positive post.......
I am thinking my problem lies in the lift pump not being connected, and possibly no restriction on the return lines(return on filter base plugged off) Anyone have any ideas what I should to to get it to stay running?
?? I appreciate the help.
