New Dist Cap, Rotor, Bushing - Now No Start 74 T/A?

[MART60]

After replacing about 35 parts on the 74 455 that sat for 32 years, I took it down the lane to get the mail for 2 days & it ran great.

But I can never leave well enough alone.

Put on New GM plug wires, dist cap, rotor, brush, and seal.

Now has Weak Spark and Just Cranks.

Just ordered the missing tach clip.

Put the old rotor, brush & seal back on & no change.

Strange!!

Thanks, One and All,
Mart

Have you replaced the coil?

No, but I don't see how the Coil that worked great 15 minutes earlier could have gone bad just by replacing the cap, rotor, brush & seal.

I have it set right on TDC now and will go from there.

Top dead center was pointing toward 8, so just to see, I moved 1 to 8, etc.

Still just cranks.

Taking the Coil off the Vette to see what happens.

Put on a Brand New Cap with rotor and everything from the 454/450 I had built in Arizona for the '79 Vette.

The same thing happens.

Cranks Strong/Weak Spark and won't start.

Where is the ignition fuse in relation to where the pink ignition wire plugs in?

Thanks,
