I do not get a cel at all ever even on starup, recently swapped motor with same d16z6. When I turn the key on I get no cel and the car starts and runs OK but not perfect. Could I have missed something installing the newe engine ike a ground or something. I know the bulb is good because I swapped it with a known good bulb, and I have checked and double checked all of my fuses.. thanks a lot for any help outt there

. Inspect the Back Up Light (10 A) fuse in the under-hood fuse box.

. Clean the main ECM ground on the thermostat housing with 240 grit abrasive cloth.

. Repair an open in the wire (GRN/ORN?) between ECM and gauge assembly.

All right checked the fuse.. again.. its good but replaced it anyway... cleaned the contact on the ground at the thermostat housing... and traced wires and there's no cuts in it all the way to the ecu.. its funny that I want the cel to come on... anything else I can try or something I might have missed in the engine install... there are only 2 engine to chassis grounds right? One on valve cover and one to transmission.. this is really puzzling me.. thank in advance for help
