Just replaced my blown motor, car started at first. ran, but then it stopped working after we restart the car. Got fuel (crack open the fuel line to see if we get fuel), spark, but i stick injector light on it..the injectors aren't firing. What could be the problem?

Jeff-

 

anybody anybody?

 

it could be your fuel injector ground. could be your wiring if you had to do any rewiring.

 

yes, check your wiring and check the resistor box.

 

I agree, I would check and re-work all my grounds by making sure they are clean and taking some sand paper to the contact points to make sure the connection is being made. Next I would try squeezing the wiring clips together while another person tries to start the car, see if you have a loose clip.

 

now...how many grounds are there? i never had this problem before and this is first time it ever happened to me.

injectors are good. i stick the injector test light on every clip and i didn't see 'em light up at all. it was running but then it just stopped....

anybody ever encounter this problem before?

yes when i had someone else do the swap the first time he butchered the harness, and blew the pr3 ecu's injector pulse somehow.

get a good meter with lcd and see if the injectors are being pulsed, then make sure the ground under the dash by the main relay is on, and also the one above the pedals, to the left of the radio. i know it sounds retarded, but the ground input for the injector pulse at the ecu is sharded with the ground input of the main relay.

the other ground input for the ECU comes from the thermostat housing under the hood. check this gorund as well. its very important. its a 10mm right by the rad hose going into the block, left of the valve cover.

if everything checks out, run continuity on all your wires, look for possible shorts, but if not that, check with a knoown good ecu, and that may very wel be the problem. sorry to say.

good luck however!

 

I'd guess main relay, which are notorius for going bad.
