I installed a new 5.7 L engine in this vehicle. The subburan is running but is giving me a prom code of 1345. Installed new ckp and checked prom - for ground [ black wire or"B"] This is good. Checked prom+ for voltage=11.47 volts[pink wire or"C"]. Checked pulse or yellow wire while cranking vehicle over this 4x pulse signel sending to ECM is good. Also did relearn on ckp, Still comming up with the same code. Where do I go from here?
have the same problem?
