All the gauges work when ignition is turned on.

I just replaced the camshaft position sensor located under the rotor. And its a big no go!

Still no spark.

Do you have power to the coil when the key is on.

I don't think there is power going to the coil. I don't have the testing equipment to figure out exactly what is wrong. I think it's going to the shop Monday. Let them figure it out.

I had the same kind of issue on my 2000 s10 blazer. It just shut off. Dumped fuel down the intake and no fire. Checked 2 spark plugs and they had spark. I checked fuel preasure and had 60 lbs. So I change coil, module, crank sensor knowing that just 2 months earlier I changed plugs, wires, cap and rotor. So I didn't look at them. Still didn't run. Took it some where to get it looked at and they found the new cap and rotor had melted aND came apart inside. The 2 plugs I pulled happen 2 be the ones that the spark could get to to ground.

I don't know how to take that one Huck? If you are talking about firing a few rounds at it with a fire arm. I've been so close! If your talking about hand crankin one?

I think it would mess up my paint.

 Any how I did check power to the coil and it's still shitville for me. What's next?

I  need a second hand to turn ignition. I got the schematic, and went to print it. My printer all of the sudden crapped out on me. I'm howling. What's next.

You'll see me on the news tonight. "Man gets DUI while on lawn mower, hasn't drank in years, just went off the edge" LOL

You want to fix it? I got cash! You want a case of beer? I'll buy it. I don't drink. I just need this giant toad to run again.

No I want to let you fix it, I got cash and beer, but no truck,you got no luck(so far)! . Don't replace anything until you prove it to be bad. The repair is the easier part... the diagnosis is the hard part. I'm trying to help you with the hard part.

I Am grateful for the help. Finding this is probably going to be harder than I can really handle. I've solved some electrical problems before. Like a fusible link that fried on an old chevy. I already checked the fusible link on this one. It really pisses me off I cant figure it out my self. I've always done everything myself. And to have to give it to some one else to fix. Makes me sick. I really don't trust any one to mess with my chit.

The pickup coil and the camshaft sensor is one in the same part as I said earlier. And it has been replaced since this all started or stopped.

It could be worse, it could be an intermittent no start. The scope of what it could be could be from a fuse to a PCM. Your be best served not tossing components to it, and getting a proper diagnosis, and repair. Sorry I couldn't help you. B)
