Cylinder 1 Injector Plug Power Cutting In And Out

[boosted_32]

hi guys was driving my car 2day and it dropped a cylinder so I took it to get looked at and they tested a few things and found that the injector for cylinder one is cutting in and out due to power? we put a test light on it and seems to work fine when we then go for a drive and it cuts out again then we check it with the test light again and theres no power getting to the plug. keeps doing this on and off and even more so when i get up it? any reason for this? any obvious thing to look for? cheers

check for continuity between the output pin and the injector pin wire....

If your not getting a signal to injector, just trace it back to the ECU; there could be a dodgy connection somewhere.

Could be happening more often when your on it, as there’s more heat, movement, vibration.

The other option, is what occurred to me. I had a cylinder keep cutting out every now and then. Two days later that corresponding injector driver in the PFC died. Had to send it back to Apexera to be fixed.
