Swapped in substitute ecu, same part number, different suffix. My ecu ends with Q. Swap ends with D. Otherwise same part number.
Verified continuity of crank position sensor center wire back to ecu harness. Verified continuity of distributor sensor center wire back to ecu. Did not check +- on either connector.
Nothing I've changed has made coil spark. Alarm did go off when fresh battery installed. Reset using key in driver door unlock.
Starter cranks normally. Just nothing works to allow the system to spark. This is making me nuts. Any help appreciated.
testing spark by grounding coil output wire to block.
check engine light on with key on.
no codes showing with obd reader.
have the same problem?
