I changed the VC gasket when i did the harness. Nothing in the harness look burnt. When i unplug the harnesses at the valve covers when it is running, the passenger nearly dies out when i do either front or back. When i do either one on the drivers side there is no change.
I did the buzz test last night and only the passenger side injectors would buzz. after running the test it came up with 11 codes.
P1271 - HI to Low side open cyl #1
P1272 - " " #2
P1273 - " " #3
P1277 - " " #7
P1274 - " " #4
P1275 - " " #5
P1276 - " " #6
P1298 - IDM failure
P1294 - HI side open bnk
P0282 - Lowside short cyl 8
p1219 - CID struck low
I think this is all from a bad IDM so im going to try to find one off another truck to make sure that is it.
I there anything else that could be making it do this?
