Rebuilt the motor and installed a new fuel system, now won't start. Details inside.
Okay first of all thanks for any trouble shooting ideas you guys come up with in advance, everyones help is always appreciated. On to the details.
Last year I had a bad cam bearing so I pulled the motor and decided to go turbo. I had the block cleaned, checked and new cam bearings installed. I rebuilt the motor will all new bearings utilizing the same forged parts and heads that came out of it. There was only 200 miles on them when I pulled the motor. Since I was going turbo I decided to upgrade the fuel system too. Triple 340's (But only running two right now) -8 AN feed, -6 AN return with an A1000 regulator.
So I installed the motor and fuel system and wanted to test start the car to check for leaks, ect, before installing the turbo kit. When I turned it over it acted like it wanted to fire right up but didn't. So I tried to turn it over again and then it sounded like I wasn't getting any spark. So I pulled the plugs and they were wet with fuel. I killed the power to the fuel pumps and cranked the motor over a few times and I could see fuel shoot out of the spark plug holes for a quick second until it was clear.
The first thing I thought is I messed up the timing when installed the cam. So I pulled the front of the motor off and verified the timing set-up and top dead center. It was dead on. I put it back together installed the plugs and got the same thing. Except this time I had enough unburnt fuel in my cylinders that it put the stress back on my starter and killed it.
Here is the things I've done so far and I am open to more suggestions on trouble shooting this or fixing it.
The only things that changed from the previous set up is the cam and fuel system.

- Verified I'm getting spark
- verified timing
- check for trouble codes (there were none)
- Verified that my fuel regulator is set at 58 psi
- installed new plugs and wires

I pulled the intake off to double check the sensors and they are in the correct spot. I am going to check the signal on the cam sensor and crank sensor tomorrow.
I haven't tried lowering the fuel pressure yet either. I am going to do that tomorrow also after I get the rails and lines back together.

If you find a good tuner, you should be able to tell him all of your mods and he should be able to get you a pretty close startup tune. There are so many variables at this point and if its purely tune related, you will be chasing your tail for awhile.
This is all assuming you arent your own tuner..
