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) |

I have little faith with parts laying in some box. Just to make me feel better, pull a injector and insert it into a jar. Pull the ECU connector off, and with one end of the jumper tied to ground, touch the other side to either 14,15,32 or 33. One of those pins will cause that injector to fire. (ignition switch in the on position)

(ignition switch in the on position) I was hopeful, but NO SQUIRT. I did get alittle spark at each connector. I pulled #4 which I have checked continuity back to the ECU connector as 33. For kicks I did touch the other connections, 14, 15, and 32, but nothing but a small spark at the connector but no squirt. Does this lead us to the injectors? ALL 4? I will have to check my records, but I sent them off for testing, etc... and have the document, somewhere. |
