Hi
I Been asked to look at a iceracing 318i with a newly dropped in a 1998 m52b52 in it. Since its a race car it will be ran on minimal wirering directly from the engine loom. However, this engine wire harness has a square plug for the power,starter etc, and not a big round one like i found online, so i cant really figure out exactly which wires i need. Has anyone encountered this square type plug before and have any info?
By using the wires from the square plug, i get relays etc to turn on, i also get power to go to the coils, but no matter what i do, i get no spark. The ecu has supposedly been flashed to run without ews, but i dont know if this is true. Will the EWS cause no spark?
Thanks in advance for help and suggestions.
EWS will cause a No start situation it should cut power from main relay to IGN switch.Try throwing a spark plug on a coil and boot to body ground? Do you have fuel? I haven't seen square connectors before either maybe on 84-85 e30s maybe? To rule out a variable is this OBD1 or OBD2?
