I carefully removed WVO controller, switches, etc. Most all of the wires i cut were "T" splices(hope you know what i mean), The fuel solenoid doesnt seems to open, but power is in the plug(test light). I can open it w/jumper and yes fuel to injectors.

There are SO many codes relating to sensors and switches that this has got to be a major connector in the harness that isn't plugged in (or equivalent), or a major power supply or ground connection that isn't.

oh my it runs!

"spark or fuel" right? So when ahead checked and re-check wires(under battery) and connections, plug and replug and so on then put the vacuum pump back on the plugged injector and pulled about a pint of fuel through, then
push IP all the way back towards engine, she started/ woohoo!
I thought i had cleared the codes but seems now they were from old WVO engine and IP.
Thx,
Theo
