OK, we've installed the megasquirt as my final upgrade after having the motor built and no spark or fuel. We've double and trible checked the wiring and bought a new crank position sensor just to see if that could be it. The settings on our computer are all set correctly as told to us By Paul at Symtech and all that happens when we turn the car on is the blue light for power on the MS unit turns on then off again we get crazy readins from it as the engine cranks such as -7 degrees intake temps in little rock Arkansas, so no way its gonna be that low and I'm about to send the box back to Symtech to have them check it out. Is there anything else i might check out that any of you may have had the same problem have done? I'm either going to buy a new box or shell out another 2100 for a tec3 which i dont have right now but i need the car running in the next 2 weeks any help would be appreciated.
