    OK I have an update: I am an ASE certified mechanic that worked full time as a mechanic for about 5 years before going back to college and getting an associates degree in business and then bachelors degree in accounting, have restored at least 20 cars from the ground up and have about 100 project cars waiting in the wings and 2 wires have been kicking my behind for a month. I don't know if it was you guy's good luck being shared or grumpy said a prayer for me but I found the problem. The professional that built my 4 wire connector (that I verified was correct and had no resistance) also built the two wire connector from the coil to the distributor but unprofessionally crossed the two wires to the wrong poles. The 11:1 383 aluminum head full roller stroker with First performance TPI injection is now running. Thanks to everybody that had an idea and especially to grumpy because it seems like every time I have an impossible issue I find the answer is provided by one of his online conversations.

    glad too see your making progress and yes,
    as usual tracking things back to the basics
    and isolating and testing almost veritably leads to finding answers!
    so , now that you located the defective wiring, how is it RUNNING?

    Hey Grumpy I am fine tuning the engine right now had to order an adjustable TPS sensor, am having an overheating problem but am optimistic that it was a hidden cut fill tank return hose below the top level of the radiator, once again it was a body shop that cut the line a while ago and I am just now locating it (my son said the brakes failed and he drove it through a small brick retaining wall - yeah right). Took my son for a ride around the block but once I realized it was spitting antifreeze I had to take it back to the shop and let it cool down. Funny when the temp started over 220 I clicked on the A/C to trigger the cooling fans and the A/C started blowing cold air, funny because the vette has been sitting for about 5 years, I didn't expect the compressor to even engage. Had a tick on passenger side, the side that the A/C compressor bracket runs over the tall valve covers of course, so I will be having to disassemble some to verify the valve lash. Like to get this one done, I am also working on a 1954 F100 full resto(4 wheel disk, HO 302, 4spd, Heidts suspension. 1969 Camaro full resto (Iron BBC 427 518HP Turbo 400), 1938 Ford Coupe original body and paint current profile (narrowed rearend, BBC 396 dual 4s, 4spd Hyd clutch), 1934 steel 5 window ford coupe (351w auto) and my nieces 1981 280ZX that has been kicking my but for about 2 years with a running issue (been sitting for many years before I pulled it out and sent to body shop then rebuilt top end), I am working on all these at the same time so always something to do.

    no the young driver was about 24 then and is 31 now, mostly just bumper, right fender and inner fender but about a year after that accident is when my son once again was driving that car and the engine washed the cylinder walls and shelled, that is why it got rebuilt. He did park my 1968 convertible vette behind his grandmothers car one time and it got backed into also. I put a bunch of time into these cars but they are still just material things but every time my children and I part ways even to this day we say "I Love You" so Ill just rebuild and go on no harm done.
