TBI/engine/harness from 87 suburban swapped into 1972 k10. Spark confirmed. Injector pulse is present when distributor is spun by hand, but not present with the distributor is installed and start is attempted by key. Any insight is greatly appreciated. https://youtube.com/shorts/P4IoR848deo?feature=share
make sure you have IGN power when in cranking position. very common for vintage ignition switches to NOT have power to IGN circuits when in the START position. i did a similar conversion in a 64 Impala 15 years ago and used the "R" terminal off the starter to achieve this IIRC.
Tayto, thanks for the reply. I will check this when I'm back at the shop. I utilized a key on positive at the bulkhead but did not check to see if it was hot in the start position. Thanks again!
Tayto! Your the man! This was the issue. Thank you!
excellent!
