I just finished putting in a rebuilt engine in my 87 seven, and it won't ignite. It rolls over, it has fuel, the oil pressures up, good battery, spark plugs are good, the leading coil is giving spark to the wire, but the trailing looks like it isn't, it was acting like it was the timing, but I looked at it and redid it so many times and it is on. If anyone knows what's wrong could you please help.

Thanks
