Ok please read as I have tested everything I can think of and I can’t seem to narrow down this problem. Here is the setup to start:
6 bolt 2g head(oring)
Car is on Speed Density
280 kelfords
Magnus V4 IM/1G N/T TB
2150 FIC
ARC-2 CDI with COP/swapped stock coil on same issue
9:1 Wiseco
Auto
The car ran fine two weeks ago and I pulled off the COP setup to paint it. Plugged it back in and no start. Started looking in to the usual spark, fuel, compression and mechanical timing. I have all four but found my arc-2 CDI status light wasn’t turning on which ended up being a dirty harness plug, light came on after cleaning but still no start. Swapped in the stock coil and same issue.
I again checked spark and fuel which all four cylinders had. I replaced the CAS and had the same result. If I take out the spark plugs, there is fuel (e85) on the piston. I removed the CAS and spun it by hand and could feel each injector as it opened/closed(2150s are loud and make a loud tick).The coolant temp sensor is working and was reading the temp in the garage. All other sensors read as they should in link prior to starting. I have proper fuel pressure (it’s logged in link) while it is cranking/attempting to run.
So I went through my ECMLink setting and everything looks as it did two weeks prior when the car was idling perfect.
If I put the pedal to the floor, the car will start but sounds like it is missing bad/running on two cylinders. As soon as I let off the gas even a little it dies and my WB in Link is reading 7.5 which I didn’t even know it could read that rich.
I have tried everything I can think of and down to thinking something in the ECU is messed up from when I unplugged the COP without turning off the battery cutoff(Only thing I can think of). Anyone have any other ideas before I light it on fire? I pulled the ECU to send it off to get looked at but that’s a hopeful solution. I took a few pictures of my settings in link to see if I have my fuel way off randomly.
PLEASE HELP!
