CEL code 4 (crankshaft position sensor)
DOUBLE POST. ALSO POSTED IN CRX FORUM ON HONDA-TECH.
1991 civic DX with B16 and PR3 ECU.
car ran AWESOME before...
then coincedence or not, somebody broke into my car and stole the tach and shiftlight, and popped my hood and stole the AEM short ram.
NOTHING ELSE.
after that, i moved the car.... drove it maybe 3-4 miles, NO PROBLEMS.
shut the car off, and pulled out the ECU (theft security)
after a few days, i came back for the car.......
wanting to race it at the friday night drags.
i put the ECU back in, and it came up with this code, and is now running like ****.
or not running at all..... more like MISFIRING. and sometimes stalling.
i checked all the wiring at the ECU side, seems fine, i even re-did the connections to be safe, same thing at the distributor side.
still, same code.
my plugs are ok.... NOT PERFECT, and same with my plug wires.... i even swapped those over with some from my EG, just to double check. (plug wires)
took off my distributor, and my points dont look awesome, and same with my rotor.
just look a little old. but then again, car was running FINE before this... almost on a daily basis.
ANYONE HAVE ANY CLUE WHY THIS IS HAPPENING?
what do i do to fix this? before FRIDAY.

Check your wires/conector pins at the ECU. That one may have come loose or isn't making good contact.
