My cylinder #4 will not fire! The spark plugs are new and I have gapped and swapped them, coils are good and I also have spark, I removed the stock injectors and they were a pretty dirty on the #4 cylinder so I swapped them with Five-o motor sports 1200cc (same problem even after swapping the new injectors), compression test was 125 all the way around (with cold and hot motor), I put a camera down 3 cylinders and they all look the same, new deatsch werks pump and fuel filter (to try and solve problem w/ no results), I put vacuum on the valves and turned the motor all the way around and they open and close properly with no leaks, and I don't have a leak down tester, but I put 70psi in the number 4 cylinder and turned the motor all the way around and there was no leaks or "weird" sounds. I have talked to a numerous tuners, mechanics, and engine builders and they are all pretty stumped for ideas of what to check next. Any ideas?? How can I check to see if there is power to the injector plug? I'm about to turn it over to Fuji so I can just get it back running now that I have my TD06SL2 20g
I just checked the voltage to the #2 and #4 cylinder injector plugs and the #2 was 11.9v and the #4 was 10.9v?
