Hey guys,
Happy new year!
I am trying to get my project running. For last 2 months I have been stuck with it not wanting to run and idle . I am keeping the OBD2 setup and a DME was purchased with EWS deleted. I am using a S52 swap wiring harness adapter.
I have checked multiple times the essentials to get the car at least running. The spark is strong, fuel feed and return hoses are hooked up properly.
The engine will crank, hesitates to start but wouldn't. It will sometimes throw a back fire out from the throttle body.
I tried spraying brake cleaner on the throttle body, just to give it a jump, and it would fire up for a second, and then dies off immediately.
I have a few reasons that might cause this, but I still want to get some confirmation and insight before continuing the diagnostics.
1. DME / ECU is malfunctioning.
2. Timing is wrong, thus creating a backfire coming out from the throttle body.
3. Cam or crank position sensor is bad, preventing the engine from starting.
4. There is one ground that is not hooked up (pictures attached below), let me quickly explain why:
I have previously attached that black ground to chassis and it sparked, so it must be a negative coming from the battery side.
The reason I didn't attach it back is because I really don't know where does it go!
This short video I took will show you which cable I am talking about: https://youtu.be/AiQeSLXx1Xs
I taped the cable in red color tape so it wouldn't touch the chassis by mistake and start a fire.
If anyone has experienced something similar to this or have some knowledge to share I would greatly appreciate it! I will actually send you beer money if your suggestion works
Thank you for taking the time to help me out as this is my first time doing any swap and I am not in the mechanics field at all. I am not afraid to make mistakes, as long as I learn from them
