Car Dies After Rebuild

[420aNEWB]

ok so i recently did a rebuild on my car low compression for turbo ...ok so i bolted up the motor and everything and i start the car and as soon as it warms up its turns off..then i try to start it it up again and it wont ... have to wait for a while for it to cool down...i replaced the spark plugs,the wires,and the coil pack, and i was looking on the search that it might be the Fuel Pump or the CAS. The only way the car wont die is if i let it cool down and then i keep the gas pedal pressed but as soon as i let it go it wont turn on and i have to let it cool down again.. any suggestions? also could the engine fan or the thermostat be a problem? please help i want to try this baby already after 2 months of downtime...


and yes as soon as it get to operating temperature.

Define "turns off when it warms up", as in once it gets to operating temperature, or once the temperature gauge starts moving, or does it go past the normal temperature on the gauge?

I would check out your IAC. We had a very similar problem with a 420a built motor i did.
