Help"" no spark.

[limelite70]

B cuda has new style electronic ingnition.
4 wire plug on the spark box.

Ballist resistor is bright on one side ,dimmer on the other.

Tried another distributor.

2 of the wires going to spark box have power.

Added 2 new ground wires recently.
Started it to drive it outside.went to drive it in and nothin.
Cranks over fine.

Thanks

Get an in-line spark tester (cheap at Harbor Freight). Try spraying starter fluid down the throat to rule out fuel. Did you ground the case of the ignition box? What voltage does coil+ measure (relative to BATT-). You can run a jumper wire from BATT+ direct to coil+ for a short-time test. That bypasses the ballast, bulkhead, key, factory wires.

Sounds like bad ground to ign box unless fuel pump quit.
