No trans is working perfectly I can load it up against the brake and it will break the tires loose . I just unhooked the edge cts2 and hooked up my flash scan v3 and it says there is a current code of p0880 ?

Attached. Looks like a power or ground problem. TCM detects power loss from battery supply at ignition off. Check your harnesses, grounding, and TCM connections.

Thank you I did that last night . Going to put a new ground from motor to batteries. Also changing the ignition today being intermittent I’m hoping that’s it

Well still can’t find out what’s making the truck stall . It will stall out after putting it in gear and giving it fuel . Stalls but starts right back up . Not getting and codes tonight . But it did say voltage is low . It’s putting 13.6 bolts out at idle . I’m at my whits end here ! New ignition switch and NSBU switch. Going to test alt next and going over grounds . Any advice is greatly appreciated.

Not setting a code when it does it . I think I got the p0880 to stop . I’ll run it tomorrow and double check

are you able to read fuel pressure?

Yes fuel rail pressure is good I can hook a mechanical gauge on the lift pump . I’m not having any issues with performance after I accelerate runs perfect . Shifts through the gears and hauls ass ! It’s just the log idle stall

I’m just learning EFI live and have a flash scan v3 . I’m reading up on how to data log now . When I get it figured out I’ll do that and try to catch it stalling .
