TPI won't fire injectors .. got oil and I think disto ref

have 1991 bird .. was v6 ... now TPI 350 .. just plugged and played .. harness CPU motor all came from same guy .. assume good and matching SD setup .. harness was cut at alt and fuel pump fan relays .. so I hacked in the V6 stuff ..

V6 ran great ..

swapped in a walboro 255 ...

VATs seems to be working .. security light out ..

got oil pressure ... by passed it too and pump comes on ... pump primes with key

I ground each side injectors and can get it to "fire" OK for a second ...

spark ok ..

put a LED on one side and a noid on the other and can't get a pulse

I think disto reference is working ?? meter was showing 1.3 volts or so at CPU pin .... thought I read 1.3v was OK ??

hhmmm.... mental note .... check TPS ......
