2006 Trailblazer EXT LS
My son mostly, and I replaced the original engine with a freshly rebuilt one, same year (4.2) - assembled block and head only. We have crank but no start. Vehicle ran fine before engine replacement (rod through engine block). We cleared codes and with no battery, shorted the battery cables together for about 5 minutes to reset/bleed down electronics in PCM. My main question is if I need to do something for the PCM to learn the various engine sensors, or some other initial process. We are brand new to working on computer controlled cars so the most basic things we might know should not be assumed. In fact, I'm only assuming the engine rebuild included the crank, cam and/or other sensors. I haven't researched where these sensors would be to even know if they are installed. We transferred the oil pan, valve cover and accessories from the original block to the new one. It's getting fuel at 55 psi.
We get the following 4 codes during crank:
1) U1000 ABS $29, Class 2 Data Link
2) U1000 XFER $1A, Class 2 Data Link Malfunction
3) U1301 XFER $1A, High
4) P0335 ENG $10, Crankshaft Position Sensor A Circuit Malfunction INTERMITTENT
I really appreciate you help,
John
