If you still have the original sensor. Compare it to the new one like I said. And if you got it at Autozone, that means it's a Duracrap. You should get one from the dealer or at least a Standard Motor Products brand.

Well changed the sensor and plugs and not even a burp. If I could've got a little running I'd ran straight to the dealer and got a good one but not even that. It's going to the shop tomorrow when I get home. I'm gonna hate what it turns out to be.

Try unscrewing the pre cat o2 sensor and see if it starts. Before talking to shop.

Am going to try that today if I can get it loose. Shop wait is a week just to look at it. I checked electrical today the dark green organe wire from the ASD to coil has no power, I jumped it and still wouldn't start would be strange if it's the o2 sensor.

The reason I suggested unscrewing the 02 is, to eliminate a possible clogged cat.

Keep in mind, the coil and injectors will only have power for about three seconds unless the PCM sees the engine turning.

I disconnected the o2 sensor still no go, I tried to remove it but it's really in there, the guy before used it mainly for mudding and on a farm so it has seen better days. I did drop it off at a shop yesterday to get looked at, it may very well be the clogged cat because it has a funny smell when trying to start, almost smells like starting fluid but not totally. I left a note and mentioned it to the mechanic. I was worried about the PCM as in they aren't very expensive (compaired to others) but nobody around here can check it and I don't think I could return it if it wasn't it, but we'll see what the mechanic finds out.
