Message: [QUOTE="D66stroke, post: 780663, member: 7886"] Tested the FICM and it was good, read between 47-49 volts. Read on another forum someone having the same problem I'm having and the same code I'm getting (P0275 cyl. 5 contribution/balance), and the guy mentioned testing the 2 pins on the injector plug if the FICM came up good to see if it's the harness running from the FICM to that injector, and that it should have 48v if good like the FICM? I'm assuming he meant the valve cover plug for that cylinder so I tested the 4 pins (there are 4, not 2 like he said) and got nothing close to 48v, just a bunch of numbers jumping around. Anyone heard of testing the plug to see if the wiring from the FICM to that injector is good? [/QUOTE]
