Stuck in Park

Sun, 09/05/2010 - 15:00
Searched for an hour. Seems it could be tps or a relay in the steering column. It shifts fine when engaged and the truck is otherwise in good to excellent condition (except a little clunk when shifting to R). Any thoughts? 91 (not 91.5) w250 Diesel 119,000 miles

Need Help!!! Please!! I've been bleeding air for 2 days!

Sun, 09/05/2010 - 15:00
I have checked and double checked all connections, the motor is in an 04 F350 so I would doubt a rusty fuel line. I can turn the truck over and get fuel shooting out of the back of the injectors. The truck will try to start, then it will go back to just cranking. If I crack the injector lines...

Started once but will not again

Sun, 09/05/2010 - 12:00
The old VE would idle but no throttle, I didn't want to fool with it...so I put on another VE from a spare motor. This one started once, had a low rough idle, I shut it down....and now it will not refire. There is air in the lines every time I crack them loose at the injector. Doesn't even try...

injector bore size

Sat, 09/04/2010 - 19:00
I know I need to just search, but I got my buddy on the phone. I'm so confused now I've got a 92 i/c motor and thought that i read that when cummins went to i/c on their motors the switched to 7mm bore heads, from 9mm bore heads, because 9mm heads were prone to cracking at the bigger bore...
