Re: Tpi won't run

Only way is to go back to the start and set the static dizzy timing ( #1 TDC ) using the mark on the balancer .
(Google how to set timing on a SBC )
Then once it starts you disconnect the EST connector and use a timing light to set the timing exactly where it
should be instead of guessing

You can disconnect your ALDL wire prior to attempting to start it. It should start providing you have your wires in the right sequence 1-8-4-3-6-5-7-2 on the distrib cap. And your distrib has to be fairly close but not exact to start also. Then use your timing light to set your timing.

Classic thing that I discovered. Once your plugs get fuel saturated, don't reuse them, Replace them. I have tried to reused old plugs by burning off the excess fuel and it just doesn't work as well as getting new plugs.
