Hello everybody,
I am working on 2006 Caprice LS1 harness. the car's owner is swapped the car engine to LS3 engine with Lingenfelter TRG-002 58x-24x Crank Sensor Trigger Conversion Module the car just running up for 2 to 3 seconds only after that the engine is shutoff.
I checked the map sensor wiring pinouts the 5v reference only reading 1.2v all time "key one, idle and WOT" and on HPTuners scanner reading 32kpa all time & I have P0641 code on scanner.
I checked the map sensor wiring from PCM to Map sensor plug it's connected perfect.
Please your help![Bang Head](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_banghead.gif)
Thanks in advance
