maybe the starter or wire connections are bad? see if theres a way to turn the engine manually so you know it's not locked up...make sure the spark plug wire is off!

Check the Fuel injection system (injectors) and the intake manifold. It might also be wise to check the alternator as well as the starter coil and also the electronic distributor

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you need to diagnosed and repaired it. The list of possible codes number in the hundreds. The code itself doesn't tell exactly what component is defective - it only indicates where to look, or what engine parameter is out of normal range. A technician will have to perform further testing to pinpoint cause and the proper repair. When the light starts flashing the computer is telling you to have the vehicle looked at now before other problems happen.

I have a 1995 Mazada 626 V6 and i had a simular problem. My mechanic couldn't figure it out. My boyfriend did the usual checks also, but 1 thing extra he raised the idle to 1100-1200 rpm's from the 750-1000 it was at...well since then no problem.
good luck
