Default Fuse 22 Blows Constantly

Summary: I can no longer drive my 2001 Coupe because fuse 22 (injector bank #2) will blow most times I start my car, or immediately thereafter.

Longer story:
Last summer, I went for a drive, about 8 miles on a 35 mph road, and parked in a parking garage. When I tried to start it up again, it idled extremely rough and dropped a "check engine" light. A friend came with an engine code reader, and we were able to diagnose it. It blew Fuse #22 (fuse 22) in the Fuse Relay Center, which is the fuse box under the hood, in front of the battery.

I have been driving it a few times a week ever since, including a few 100 mile trips. Saturday, being the nice sunny day it was, I took it "around town with the top down". I even picked up my wife at the Acura dealer while her car was getting service.

We went shopping in the mean time, and when it was finally time to head back to the dealer, my fuse blew again. Luckily, we were parked two stores down from an AutoZone, so I purchased some fuses, and we made it back.

Then when we got home, we tried to go out for the evening, and it blew a fuse again, I drove 2 blocks, and it blew another. Then I went through 2 more fuses, and it blew all of them, so I had to drive home on 1/2 an engine. Crap.

So, now what? I searched, and could find nothing on the forum about this.

Sounds like a wire to the injectors is shorting to ground. There are a few threads on a wiring loom that follows the back of the heads getting chaffed and shorting to ground.

Sure, sounds likely. Thanks, I'll take a look.

You can try checking with an ohm meter from the fuse location to see if it is grounded. It may still be grounded and could confirm. Do this with the engine off. If you need more help on how to do this let us know.

Thanks dadaroo, good suggestion. I am familiar with how to use a multi-meter.

Had the same issue. Pinched the PINK power wire. Remove the intake manifold and strip down that complete wiring harness and look for the damaged wire.

Hey everyone, and especially Bill, thank you.

This is exactly the problem I was having, it looked identical to the photos Bill took. I assume it is now fixed (although I won't really know unless I get stranded).

I will be driving again tomorrow to test it out, and I will be buying yet another box of fuses as my first stop (just in case).
