i just bought this vehicle in a non-running condition. the engine won't run at all, it cranks, but doesn't fire up. I have checked fuel, and there is no fuel, nor is there spark, i've tested the main relay, and it checked out good, all fuses are good in both main box, and inst. panel box. i've had the igniter and coil tested and those were good too. the weird thing is that when i have the main relay disconnected from the harness, the check engine light and led on the ecu are lit up. but when i reconnect the relay, it clicks, and both check engine light and led on ecu turn off. i know that when the ignition is turned to the on position, the check engine light is supposed to illuminate for a couple seconds then turn off, but it doesn't turn on. Only when the relay is disconnected the check engine light is on and stays on when the ignition is turned to the on position. Please help!!!! THANKS

 

its a 89 hf with a d16a6 motor did u use the si or hf harness

 

i wasn't the one who did the swap, but it has the original hf engine harness in it. i believe the car ran for awhile with the hf harness and si engine, but it sat for a really long time after it wouldn't start.
