--INJECTOR FAULT(S)<-- possible source of the fault

--FUEL PRESSURE<-- possible source of the fault

--OXYGEN SENSOR<-- same

--AIRFLOW METER OR MAP SENSOR<-- same

--IGNITION<-- same (you get the picture)

--ECU<- probably NOT the cause of the problem, but still a possiblity






code 43
STARTER SIGNAL--NO "STA" SIGNAL TO ECU UNTIL ENGINE SPEED EXCEEDS 800RPM <-- once again -- the code that the ECM sees
--IGNITION SWITCH/CIRCUIT<-- possible source of the fault

--ECU<-- ECM (ECU) is typically NOT the cause of the problem
