Ok I think I am good on the seat belt relay. YLW and YLW/red are spliced. And I have checked for continuity all the way from the starter to the key on that wire.
I have spark, points checked too. I have fuel pressure, about 40 psi, checked between p-side fuel rail and cold start valve. Starter works fine oil pressure builds, light goes out on the dash Engine timing is still at rebuild setting...0 TDC. Re-built FI & Ignition & Alt harnesses I did have trouble with the key switch, so the steering wheel is out, levers are not connected and I turn a screw driver on the end of the key connector to fire the starter, should not be an issue, correct? I got the L-jet trouble shooting "no start" pages to try tomorrow. Any other ideas? I am baffled. (IMG:style_emoticons/default/confused24.gif) |
