No fuel or spark
I just got done puttin on the snail, and went to start the car up and nothing. I double and triple checked everything, and nothing. I checked the spark, non and the fuel, none. I have a 99EX wiht anm obd2->obd1 wiring harness running a P06 ecu with uberdata. Could this problem be from the ecu? My CEL is on and so is my SRS light. The car will crank and ----, just not that final push to start. I think its either the ECU or the harness. Xenocron if you read this, message me cuz if its the harness I have to talk to your buddy that made it for me. And Im sending my ECU back to kevin this week so he can double check the map on it. Someone also said it might be a bad chip? ???

Re: No fuel or spark
All of the above are possible. Bad chip, fucked harness, or bad ecu will do that. Your car is an EX right? Is that P06 converted to VTEC? Thats not why it wouldn't start but I'm just curious.

Re: No fuel or spark
If the wiring harness was bad, would the car even crank? Like if I took out the ECU and tried to start it, would it even crank or do anytying? like the dash lights and ----?

Re: No fuel or spark
Should be drivable as long as you don't hit boost. Try to start it with your stock ECU. That way you know it's not mechanical and realize it IS in fact the ECU.

Re: No fuel or spark
Your stock ECU wont run the car without removing the larger injectors. You can disconnect the waste gate arm so it doesn't boost.

Re: No fuel or spark
your car wont run at all with 450's in it. It will just foul the plugs and flood.

Re: No fuel or spark
You sure you have all of the Harness and ECU plugs pushed all the way in?
I've done that before personally on a customers car and then walked around in circles for damn near a half hour before I realized I didnt click everything down good and proper. Did you try taking the chip out and cutting J1 to see if everything would prime correctly? |

Re: No fuel or spark
Did you put in a resistor box?
