New Life for a truck passed its prime

[flattopwill]

I told my friend to recheck all his wiring today. He said he realized he misplaced the brake switch wire. That explains why I don't have tcc lockup but does it necessarily explain the tcc code it's giving?

We plugged in a Tech 2 scanner today and logged my truck driving down the road. It showed the computer giving the right commands but the trans just isn't receiving them correctly for some reason. I still wonder if it could be a shift solenoid. I was sure it was shift solenoid A but then after I looked at the range reference again I noticed that to have reverse shift solenoid A has to be functioning. I have reverse no problem so I don't know what's the reason for not having 1st or 4th. If I have a tcc pwm code will it disable 4th gear also?
Please help?

I hooked a fuel pressure gauge to my rail today in an attempt to diagnose my starting problem. The fuel pressure does not bleed off quickly and the truck will start and die all while the pressure is still high. If the truck is cold it does not have any problem. If I give it a little throttle when I start it it does not have a problem.

Red? C3? Have a I run out of help me credits?
