Hey guys , i know this has been covered multiple times but every other thread I have looked into never has a direct answer!
My sr was just freshly built and when trying to swap it back in i couldnt get it to fire. I know, air, spark and fuel are the 3 things you need.
I know we have air, and when i pulled the spark plugs they were wet, so i know we have fuel. So that leaves it to spark. I pulled the plugs and the coil pack and turned the car over while the plugs were on the valve cover and only cylinders 1 and 2 had spark.
I tried pulling codes off of the ecu and came up with 55 so i know it is fine.
I checked continuity to all of the wires and they are fine.
What else can i do ??
Really relying on you guys for this one.
