will the injector default closed/open if there is a connection issue? Truck has 57,000 miles FICM harness does not show any signs of rubbing through on the bracket

When my harness rubbed through and started grounding out she went into a "limp mode"
The engine light came on and the injection felt like it was only occuring in half of the cylinders- felt like a toyota 4 cyl with 75 HP. This may not have any relation to your problem but I wanted to share the details of the failure.

if it was the harness it would be in limp mode and sound different.

this isnt a harness problem. bad injector, or other internal mechanical problem.

did you ice pick #7 as well as #2?

i agree with ben it sounds nothing like mine did when #2 lost connection but ive heard that when #7 looses it you only loose that cylinder

ok, I was just wondering. if the balance rates were effed up in #5 i was thinking maybe it could be trying to compensate. but if the code is #5 that has to be #5.
