In order of failure rate you should check:
1) DIC (the red module sitting between the cam banks). This may or may not throw a code (random misfire or a specific cylinder misfire). The easiest way to check this is to simply swap in a known good DIC and see if this fixes the problem. You should also check your plugs at this point and ensure that they are gapped no larger than 1 mm, as overgapped plugs are the primary cause of DIC filures..
2) CPS (crankshaft position sensor) located on the right front lower corner of the engine block. This should throw a code, but may not. I do not have access currently to the electrical specs you should be able to read with a multimeter;
3) Fuel pump and fuel pump relay. To check this, remove the IAT sensor in the throttle body transition casting and spray starter fluid into the throttle body. Replace the sensor finger tight and crank the car. If it starts and runs until the starter fluid is gone, you probably have a pump or relay issue. Raise the rear seat and hammer on the top of the tank next to the fuel pump assembly with a large rubber mallet and then try to start the car. If it starts and runs, your pump is probably failing. Check the relay under the dash regardless to ensure that it is working. You should be able to hear the pump run when you turn the key to the on position, especially with the rear seat up.

it is possable/likely a bad ECTS (engine coolant tep. sensor), this can cause the injectors to allow to much fuel into cylinders and cause a low compression and or flooding situation, good luck, marty
