no ignition signal

[adrenalinejunkie636]

I have a modified 95 talon 420a that we had to rewire and install a new computer and crank sensor. It was firing randomly and actually started briefly once. Now the computer (ems pro) isn't showing to be recieving a good crank signal and doesn't fire at all. Any idea what may be the problem.

Are your wires right position for your firing order. I tis possible your with the rewire and computer change when your crank sensor triggers the engine tss in a different position then what the computer thinks it is. A ruff way to check is when your computer sends signal to fire, is the cylinder trying to fire valves closed and piston at TDC. May be as simple as re route in plug wires.
