Yes i did replace the Crankshaft sensor, it still no workie. The tach is not showing RPM's when trying to start. Im not sure what the lift pump is that you speak of, but the fuel pump and all the relay's click on and are good. I attemped to find the IDM, but had no luck. i heard it was located in the drivers side fender, but did not attempt. Needless to say, i have done all that i can do with the engine to try to get it to work with out going elbow deep into the engine. The business i bought the truck from is going to pick it up tomorrow to have their Mech work on it. Hopefuly he can fix it. Thankyou all for your help in this matter.
