Hi Gang,
I am wondering about a problem I'm having with a no start condition on my buddy's 2001 LB7 dually with 12,000 original miles..
Here's the deal...
1. He had leaks under the drivers door when he shut the truck off. It still ran but kept getting worse. He comes out to go to work and tries to start it and it cranks fine, but won't start...
2. Buys a brand new AirDog and installs it. The hose to the engine is run up to the connections underhood to bypass all the leaky lines. Fire up the AirDog and find a bad motor out of the box. Get that fixed and get the system bled.No leaks anywhere..
3. Replace the Puralator Filter and find a lot of crud. Install a TP3018 and bleed again. Plunger hold prime and no leaks. Also pulled the sender to check the pickup tube. That's fine..
4. Check rail pressure on crank and get 22K on my Edge Insight.
5. Security light is on after cranking, check for codes and find the antitheft code. Do an ECM relearn and clear the code. I was hitting the starter for a few seconds between each time, and don't know if it makes a difference. I read that your supposed to just do a quick bump. Buddy says that the security light was always on when he drove it. (?)
6. Find out there was a BullyDog Triple Dog tune in it, so returned ECM back to stock.
7. Check FICM wiring for rubbing and shorts along with the bail connectors..
8. Found the thick ground wire rotted off the frame and reattached it.
Guys....I am stumped...I appreciate any more ideas....Thanks..
