As in reset error codes? :confused: If so just use a code reader and erase the codes... Pulling the battery cables will erase the APPS sensor calibration but nothing more...

I've tried the scanner but as soon as the ecu gets power or at the first attemp to start the CEL comes on :mad: I seen a tread somewhere about resetting the ecu but can't find it,I think it was something like pulling a fuse or related I will keep searching thankx anyway.

If the CEL light is on its because there is a physical error or problem and yes its in limp mode if the light is on... So what error codes do you have? :confused:

I believe it's 0234,0235-0236, I also go an 1688:eek: I think but this one came on after I pulled the relay from fuse panel in engine bay. I also replaced the batterys and need to recheck for new codes. :cry2:

Well the P1689 code is cause from the fuel pump relay... The P0234 and P0236 are MAP sensor codes. The Banks otto mind might be the cause of the errors if you disconnect in and reset the codes and they remaain off the you know you found it...

P1688 is a internal failure of the vP44... Sorry!

Sorry to hear about that. What kind of lift pump are you running?

Good question? Also do you have a fuel pressure gauge in the cab? :confused:

Like Racer-Dan found out he replaced his stock with another stock assuming the stock pump would be fine for stock setup... There is a post here with 12 PSI at idle and dropping to 7-8 PSI WOT... So I highly suggest oyu get a gauge soon...
