I can't find my compression tester's adapter to fit on the FC's plug but it sure sounds like it has compression to me.

The min fuse is working great it isn't blown at all nor corroded.

Tony- The battery is my Sport's battery. It has also been connected to a charger so it should be fine.

I am giving it a rest right now so the charger has time to recharge the battery.

I took a spare plug and put it in the wire. Cranked and looked for sparks. Switch to L2 from L1 and repeat. Both have spark.

AFM connector? No vacuum leaks? Severely flooded? Wet spark plugs?

What does it sound like when you try to start it? Tried unflooding and adding a little oil to the chambers to up the compression?

It sounds like my N/a with open header. The car just has the down pipe because I just want it to run I had removed the rest of the exhaust for now.

I unflooded it a couple of times and no go.

It originally had some two stroke oil from my pre-mix stock in there but I am pretty sure its gone now lol.

Ha! You call that severe? My Engine was just recently overflooded due to my secondary rear Fuel Injector pissing out fuel when the Ign was ON (running a Microtech so the FI's are configurated differently). It was so backed up with fuel that the Intake runner was filled up and raw fuel was making It's way out the Exhuast.

Does it sound like it's trying to fire (ie. pops)? Or just spinning?

What caused the problem? Did it just not start all of a sudden?

thats not severe.. mine has been flooded for 4 or 5 days. i tried to unflood it so many time i forgot how many times i tried..it still wont ******* start..i ordered new plugs and my jackass friend forgot to bring over his voltmeter to see if im getting spark and to see if my CAS is working..its seriously pissing me off.. i may try again today if i feel like getting really pissed...

EDIT: aaron do you happen to have a picture of the main fuse box under the hood? (i.e. what fuses are what..) i cant find one anywhere..not even the haynes manual..

I just opened my present from my rx7. I guess it thought a good gift would be to not start. Great. I think it's flooded. At least, I hope it is.

I thought you were the master rotary mechanic and you would always make fun of the TII guys who couldn't get their cars running. What happened?

Make sure the spark plugs that you're using the engine are firing. It's possible to flood the spark plugs so bad that they stop firing. At least you know your coils are fine.

The last thing you need to check is ignition timing. You'll need a timing gun for that.

Spark + fuel + proper ignition timing = starting engine

I never said I was a master mechanic. I want to learn and become close to the other well known guys but I am still learning. This is the first TII I own so gimme a break. I have gone through a lot of work to get to just this point where I can try to start the car.

I also wanted to add that people change. In the past I may have been a bit(using the word lightly as I was harsh) of a dick but I can change. Remember I am only 19 still fending off childish attitude and habits.

Yeah but can I check the timing while just cranking? I thought it had to be idling to check the timing on the car. :/

By lining up the marks, It'll be sufficient enough to start It up. It's when It's running, you will have to make minor adjustments to the CAS. Be sure to rotate the Crank to the Yellow Mark first before removing/stabbing In the CAS.
