1999 Chevy Venture will not start

[joeshannallie]

Got done with replacing head gaskets and intake gaskets, Van started fine and I backed it out of the garage. Left it running and put down ramps and drove up on them so I could get under and connect the exhaust. Got that done and then got back in it and all it will do is crank and it will not start now. It also has a new cam shaft sensor( wire broke on old one). I can hear the fuel pump when I turn the key. It is like now there is no fire to start it. What could be wrong? What do I check? What causes it to fire? If something was connected wrong, would it have still started and then wont do anything but crank? Got dark on me and started raining so I say tomorrow is another day. I feel it is something simple. Please someone reply and give some advice. It will be greatly appreciated.

Try having someone crank it and see if you can feel it puffing out the exhaust. Or just top it again and try starting. You might have a plugged cat. Also check your ground wires it could have been snug enough to start then got bumped.

[IMG][/IMG]Well I got up this morning and put the van back up on the ramps and got all comfortable up under it. Hooked my big bright light up and guess what I found? I found the crank sensor crushed flat as a pancake between the exhaust flange and the rear exhaust manifold connection. So please everyone look at the pic and realize that it could happen to you when you dont pay close attention to what you are doing. Also thanks for the advice.

Awesome way to go tracking that down. We all get in a hurry and make mistakes.
