Hello I'm new to the site & software. I have been building & tuning cars for many years now. With that said this project & HP is new to me.

Its all in a 84 Chevy C10 short bed. Its mini tubbed & is running 315/60/15 Micky Thompson Drag Radial. Truck weighs 3900 w/driver.
I was handed this project after 90% of this was done. Since I got it there has been a issue with the idle. It will be fine for a while then go into a rolling issue where it sounds like it has a Very big cam. Since I got the HP Pro & was able to monitor live pids I noticed it was running warm after sitting @ stop lights. We have been in the low to mid 90's also. Anyways he said the thermostat was factory so I replaced it with 180. I went into the tune & modified the fan settings & idle command speeds. After I did that last night I went to start it this morning Nothing..... Cranks like NO fuel. I took the air cleaner off & sprayed some WD air inlet tube just to see if it would try to run..... Fired right up for a mili second..... I remove the fuse that goes to the air/fuel circuit in GMPP's fusebox it controls the throttle body & fuel pump. When re installing the pump runs & the throttle body opens & closes a couple times. It will fire right up just fine after doing that once or twice. If it then sits for more then 20-30 min it acts like No fuel again & you have to remove fuse a couple few times. Twice now when doing this procedure it starts & is pig rich..... You try to give it fuel when doing this & the pedal does NOTHING! If & when it stalls or you shut it down with key on pedal still Does NOT actuate throttle body.
I'm getting SOOOO frustrated with this thing I'm ready to burn it. There has been MANY MANY prior issues I have Already had to sort out. I just got done running & soldering my wires for wideband 02's. I will Try to start her up & get some data logging for you guys to view.
PLEASE HELP IF YOU CAN!! It might be something simple I'm missing from lack of sleep & exhaustion.
Thanks Any & All input!
