we have a 93 camaro v-6 engine, engine is missing at all rpm's, ecm is setting a code 36, we have replaced coils, plugs, wires, ignition module, 24x crank sensor, cam sensor, but not other crank sensor the 3x or 7x either way, have also replaced all 6 injectors due to leaking, have also replaced connector to 24x sensor due to exposed wires, cant see any other obvious damage to wiring, short of running new wiring for the circuits in question does anybody have any knowledge of this code 36? any similar problems and was is it resol ved and how.

 

this is what i have in my book. hope it helps cause it sounds like uve replaced everything but the ecu. the missing last line in the one picture is, 3. if ckt 623 is shorted to voltage , this will set both dtc 17 and dtc 36. i got to close trying to make it readable. anyways im not really up on the 6 so thats all i got.

 

Be sure to run a few tanks of fuel system cleaner for good measure too. Be sure your wire routing is good. On my '95 3.4L I got this problem from a bad injector. Sounds like you should do a fuel system pressure test, maybe a bad fuel pump -- has the fuel filter ever been replaced? Also spray some throttle body cleaner in the intake to clean any carbon deposits.

 

thanks for the reply, but yes the fuel filter is new, injectors are new, and fuel system pressure is fine 38 or 40 lbs, im leaning towards a damaged ecu due to the wiring for the sensor having been previosly shorted out due to missing insulation on the wiring at sensor, any thoughts?

 

Might be worth paying a good shop to do the diagnosis and they can check it out to pinpoint the problem via a flowchart, get an estimate and do the work if you don't like their price to fix the problem(s).
