Diagnostic Connector Broken?
Went to hook up my superchip max micro tuner this weekend and it didn't come on. I was wondering if there could be a blown fuse or something controlling the diagnostic connector, or is the chip broken. If the chip is not longer good, can I just take my truck down to dealership and have them reflash my truck.

Not positive about the '03 but my '02 has a shared 20A fuse between the cigarette lighter and the OBD II. It's number 12 under the dash panel. You could start by looking there.

Hard to say really.. i've blown it a few times by accident. Once when I shorted it out with a DVM and once when I overloaded it with a power inverter. I guess you could replace it and hope for the best.

I think the fuel bowl is linked to the PCM fuse (33??). I'm glad to see replacing #12 got you back in service!
