94 twin turbo stealth wont start

I just recently put my engine back together with the heads jrod (from Oklahoma)sold me. Only thing i did different when i put it back together was vac reduction. This was done following the wiki-how section of the forum.

I have fuel and fire for sure. She comes to life for about 5 seconds at about 300 rpm and just falls flat on her face. I can push the pedal in and everything, completely un-responsive.

When it falls flat on its face, it cough's out of the exhaust side.

I cant seem to find my issue... putting the motor back together was one thing but trouble shooting what i have going on is different for me. I have never heard a motor do this before.

Thx for any help

Recheck your mechanical timing first.

I was a tooth off on the front cam. The other 3 cams were perfect.

Well the front cam is a exhaust cam, might explaint the coughing out the exhaust. Should still run though. I would suggest a perssure test on the intake, did you make sure the MAF is plugged in ? Also a compression test would be a good idea.

I have no had much time to really do anything but check what i have done. Everything is plugged in but the front o2 sensor.
Oklahoma just had there statewide meet so i had to leave my car for 2 days. Ill read up how to do compression testing and do it.

Why is the front O2 not connected, I believe it needs to be hooked up to run, not sure though maybe it would just run bad.

I dont even have all my exhaust hooked up but i was under the impression turbo cars dont need back preasure. Ill get that sensor hooked back up but i dont think it would keep it from starting.

Plug in the front o2.

my front 02 reads 0.00 volts at all times (its even new something else is wrong). Having a bad front 02 wont make your car not start.....
