Hey guys I'm back.

So we went over to pull my 924 out of storage, we replaced a few questionable looking fuses, rotor and cap, and put a new batteryin her. She cranked up and drove right about 30 miles away, we parked her and called it a day. Yesterday I went out and attempted to start her up in order to make an interview, and the engine made an interesting jolting sound (like something had be struck wrong) and then began to backfire instead of reving to life.

After careful inspection it was discovered that my distro cap had come loose and was sitting at an angle. I check the cap, and rotor for damage and when none was found placed them corectly and attempted to start her up again. Alas nothing. As it was constantly backfiring we decided to change the spark plugs as they hadn't been changed in a pretty good while. ( The plugs were removed one at a time, reconnecting every wire as I went.) No help there. it was then decided that my timing was off, and that I would neeid to have it reset.

At this point I grabbed a wrench set and begin setting my engine to TDC. After that I set the rotor to about 5 degrees before the contact for spark plug one.

Here is where life gets interesting. I turn my key to start the car and hear a bang several people mistook for a gunshot, and my roommate tells me there was a pretty good size flame accompaning this bang out of my tail pipe. I'm down for the count till tomorrow as my battery has been drained over the past day of attempting to get her to start.

Any help would be hot, I've got a deadline of 15:00 tomorrow I'm attempting to meet, but if thats not possible it's just not possible.

If needed for faster answers and contact I may be willing to take trouble shooting to phone conversation to help speed things along. Thanks for the time guys.

Partial failure of the timing belt (missing a tooth or two)? Perhaps this has resulted in your cam timing being out a little bit.

I've checked the teeth over, and none are missing. That was one of my first fears when we decided timing.
