there are several grounds in the engine compartment. the ground i'm refering to is the ECU, Ign. Mod. etc ground. according to the schematic, it comes from the battery NEG to the chassis, that connection point at the chassis is where the the ground circuit i'm talking about is. it will go through a connector in the same area and the wire will be Bk/W.
since the MIL is on during crank. check voltage at the DLC (Data Link Connector) Pin # 13(i believe it's a purple wire about center on the short side of the connector) and Ground with key ON.
is there more than 9 volts?? if so, there is a short to power in the wire.
if not, check resistance between ground and ICM pin#4 Bk/W wire. should be less than 5 Ohms. also, check resistance between ICM Pin#9 O/R and ECU Pin#23 should be below 5 Ohms.
