I shouldn't have been surprised! So GM will fix my car but won't provide me a rental while its being repaired! What crap lol your warranties are half. After they determined it was covered under the corrosion warranty and would take a week to fix GM declined my request for rental car reimbursement. My back doors have begun to rust and I spoke to GM and they advised me to take it to a authorized repair facility which I did. Speaking of GM, they have a corrosion warranty for this vehicle. I don't feel comfortable paying 100 dollar an hour labor rates for them to tell me some random crap that is not even related to the problem. As for the GM rep that will probably chime in on this post no I'm not interested in taking my envoy to the stealership. Well GM decided it was a good idea to use a Hz frequency signal instead of a 5v or 12v signal to activate the coil (Really GM?) guess who doesn't have a digital multimeter that is capable of testing that ? This guy! So I'm at a loss as to why I'm experiencing a misfire unless the coil is losing the signal from the ecu after a load has been applied and why did this heal itself 6 months ago? Hopefully someone has experienced this and can shed some light on the problem. That leaves the signal to the coil from the ecu. I have checked the power, ground and reference ground for the coil and they all preform as expected. Guess what it still misfires, but only after driving 40 feet or so. Also checked the wiring harness for the injector, it's getting signal to activate. I have checked the spark plug, spark plug wire, ignition oil, fuel injector and compression. The oil pressure sensor is acting up again thankfully it's under warranty. At the same time my oil pressure sensor failed. This happened 6 months ago and healed its self before I could start the diagnosis. So on with it, cylinder #4 misfire code P304. It's funny my last post was exactly one year ago this month. Before you spend lots of money diagnosing, CHECK THESE FUSES!!! I googled everything trying to find a solution and seeing all the problems people are having very similar. Now I have turned it off and on 10 times. But 10 minutes ago, my Envoy has been sitting for days. Not saying its going to take all my worries away. SUCCESS!!!! I spent days trying to find out the start problem. The fuse was intact but the metal was loose in the fuse. Just started going through what all the fuses said. Also just for information 4 wheel drive unit did not work all last winter. Soon as I pulled this one, the Envoy shut completely down. Also there is a PCM 1 as well, #28 under the hood. 10 minutes before that, it wouldn't even turn over. Replaced it and the Envoy started right up, registered full tank of gas and a full battery. (Number 10 FUSE) under the hood, PCM Module B was partially melted. Finally would not start at all! Would not click, showed dead battery, and no gas. Had it towed to my local garage, backed it off rollback and started right up. Showed no gas, even though tank was full and AAA said battery was completely dead. Went into a facility, came out and envoy would not start. About a month ago, I took a drive with no warning something wrong with my SUV. Just wanted to tell my story and hope it helps.
