I bought a PPEI Autocal with Kory Willis tunes and a dsp5 switch, hooked the pins up properly in 49 and 69 on ecm wiring harness, but did not remove my battery cables while doing this, now truck will not start, fuel gauge shows no fuel, not getting wait to start light, etc. Autocal is throwing $0280 and $0281 dtcs and will not clear. CAN SOMEONE HELP?

Check and make sure you plugged ecm plug back in right. Check fuses
