2003.5 Mazdaspeed Protege
I recently bought a 2003.5 MSP. The car did not run when I bought it, it needed a head gasket. I replaced the head gasket, timing belt, water pump and some other small things. I put everything back together, went to crank the car and it won't start. The problem is that I only get 2 sparks from all the plugs when I first crank the engine and then they stop sparking no matter how long I crank. I've replaced the Cam position sensor, checked and rechecked my timing, replaced the crank position sensor, I'm at a loss now. Only other things I can think of is that either the ECU is bad or the alarm system is somehow interfering with it because the alarm acts up occasionally. I don't know if there is any way to test the ECU to see if it's bad, I don't want to spend the money and it end up not being the problem. Any tips, advice or help would be very much appreciated.
 
I know theres a way to reset the alarm but i forget how lol im sure somone here will chime in shortly
 
The easy wayto test the ECU is to borrow someones car and put your ECU in it.

Do not reverse this porcess.. If your wiring is Pooched, then you might Pooch the good ECU..
