If I remember correctly, you will need to bleed three injectors to get it to run. Then hold your foot to the floor and it will help bleed the other lines. Sometimes they can be a royal PITA to get going again.

Just like Tom said, Crack 3-5 injectors, if possible, then turn the truck over for 25 seconds, then let it rest for 2 minutes, then try again. When you get fuel from the cracked injectors, then tighten them up and try to start the engine.

Also, did you prime the system by bumping the starter and letting the airdog run to fill the lines up. Did you let some fuel run from the Schreader Valve on the Bosch VP 44 before trying to start it.

Remember, these engines use very little fuel to start, so when you are trying to get it going, it may take a while.

We did find the washer thank god. We finally got it running. However, after getting it running we drove it so we could open it up a bit and get rid of the excess fuel and after parking it for a while it would start and run fine in park and neutral but as soon as i pit it in drive or reverse it dies. If i hold my foot to the floor i can barely get it to chug and stay running

Since you disconnected the batteries for a time, you need to reset the Accelerator Pedal Position Sensor or APPS sensor.

Unhook the batteries, turn on the headlight switch.

Wait about 10 minutes, then turn off the headlights and hook up the batteries and then turn the truck without starting and press the throttle down slowly and return it slowly.

Turn the truck off and wait about a minute. Then fire it up and see if it is better.

Ill try that today but but I dont THINK we disconnected the batteries. However, it sat for a couple months and they were pretty dead and I had to charge them so may. Ill have to ask the other guy that was helping me and seeif he disaconnected them. But if that was the case do you think it would run fine to run it around the neighborhood for 20 min? it hesitated once in a while but we drove it around for about 20 min. After we got back and it sat for an hour or so THEN it did what its doing now

Even though you did not disconnect the batteries resetting the APPS sensor would be the first place to start. After that then I would start checking for a slight air leak in the fuel system.
The procedure that Stodg said is correct. Turn the light switch off then hook up your batteries. The reason for turning your headlight switch on after disconnecting the batteries is so that any residual voltage in any of capacitors in the PCM and ECM has someplace to go so you start out "fresh" when you hook up the batteries.

That's a very valid point. I didn't think about air getting in.
