Engine Cranks but wont start
Hi all, I have a 2002 F350 duly I drove home the other night, parked in the driveway and went in and had dinner. About an houre and a half later I opened the hood and repaaced the G P R wire for wire to terminal for terminal. went to start the truck and she cranks but will not start. I connected a O B D 2 scanner to the diognostic port and in says it can not connect so I don't have the benifit of any DTC'. any help or ideas would be greatly appreciated.
Thank You,
Mark

Do you hear your fuel pump when you first turn the key on?
Is there any smoke out the tailpipe while cranking?

I checked every fuse with a multi meter. No sound that I can here of fule pump. No smoke from tail pipe. I do here a relay clicking when i turn the ignition switch to the on position. It is relay# 303 (Injection Drive Module Relay) i changed relay and it still clicks untill you turn the key to the off position
Thanks, Mark

Payson thankyou for replying, The batteries are up tp snuff and the engine cranks fast. However the I D M Relay clicks as if it wern't getting enough power to pull it in. I took a 2 gage jumper cable from the battery to the power lug of the fusebox just to make sure I had proper voltage to the fuse block. Thanks Mark

Like Robin said, no smoke means the injectors are not firing (or there isn't any fuel available). There was a thread a while back where someone had no voltage at the fuel pump. They found a defective wire at the glow plug relay, fixed it and their fuel pump started working. I still don't know how that had any play but according to the attached wiring diagram, the keyed power for the glow plug solenoid is on the same circuit as the fuel pump so that could be your issue. Depending on how you wired up your manual switch, you could have affected the fuel pump somehow. Again, I am not sure how that can happen but I just remember that thread and how the OP solved his issue.
Here is the diagram.
