havent checkd fp yet

Id check lift pump pressure and are there any codes present?

havent checked yet i forgot wat the codes wer when we scaned it its been sitting for a mounth tryd the ecu today it was worse tac iol press and temp gauges didt work the ecu was off a 99 truck

Yeah they read differently than the later ones. I would see what codes are there and then lets us know

found also coolant is seaping out of the passanger side in the front next to the ther housing but no fluid in the oil yet and its very so leak
