Hooked to the sled for the first time this season today, truck would not fuel. Leaving at 4200rpm and it would fall right off, no smoke until below 2500rpm. Thought it was something with the tuning so i when back to the settings i was running last year (smarty) still the same thing.
Checked the codes and aside from all the codes from the missing auto transmission, there is the P0108 MAP voltage high.... From what i have found there are 3 things that can cause this..bad sensor, short to power, or bad pcm. i changed the sensor, no fix..

Does anyone have a wire diagram if the engine harness so i can try and track this down?

Any info would be appreciated..
 
see this is what ive dealt with since i did my stick swap on the 04 id love to get true full fueling
 
This is a new problem. look at my avatar pic, no fueling problem all last year.
 
Same exact problem I had in 2010. It ended up being IAT sensor but truck was only throwing map sensor codes. Anyhow your on the right path.
