Car Won't start now..

[boostineclipse]

Okay.. I did the timing belt change on my car.. I am sure that all the timing marks were algined.. now I go to start it up.. and nothing.. it just cranks and won't fire up. The only thing that I can think of is.. I don't remember if I tightened down the tensioner pulley all the way. I MIGHT have forgotten it.. could this be the problem?

Did you set the tension on the belt? or did you forget to tighten the two bolts holding the tensionor in? If the timing is right and theres enough tension on the belt it should start. What are the steps you did when changing the belt? also check your CAS.

I followed the VFAQ. I am more then postive that I tightened the bolts to the tensioner. I no longer have the 2G Cam/Crank sensor. Went with a 1G.. so I am sure thats not it.. unless that decided to all of a sudden take a crap on me

Well make sure the 2 notches on the cas are lined up, if there backwards it wont start.

Didn't touch the cas on the timing belt install.. since its on the other side of the engine.

You can borrow my compression testor to make sure you still got compression. If you do have compression, check for fuel. Simply disconnect your fuel rail and point the end to a cup. Try turning the car and see if fuel spits out. If that checks out, pull out a spark plug still connected to the wire and see if it trys to fire.

Thanks Manny, any chance I can swing by in a little bit to pick it up? I'll give you a call

I just went out and checked for Fuel and Spark.. I had both. When I pulled the first spark plug.. it smelled like it had a little bit of fuel on it. I pulled another, and it had some also.. though not as much.

How do you know your getting spark? Did you point the sparkplug connected to a wire close to a ground in the engine bay to see if it archs? If you have spark and you have fuel, then the only thing left is your firing order or your compression based on your timing alignment. Does the engine sound any different as it trys to turn? A compression-less motor will sound like the pistons are just turning effortlessly even when the sparkplugs are in place. An engine firing in the wrong firing order will sometimes sound like the engine tries to catch but doesn't, or sometimes the engine will stop cranking for half a second and then try again.

Yup.. that is how I tested for spark. The motor sounds like it wants to fire up.. but just doesn't, seems to sound like its backfiring alot when it does try to start up also.

Your using a 1g cas, right? Do you still have your crank sensor on your car? If so, you can rewire it back to stock, and just leave the cam sensor unplugged, and try to start the car. Your car "Should" start with just the crank sensor installed. If you do decide to test it like this, dont forget to swap your spark plug wires back to stock.
