new flame for old candle
Hey,
Have an 88 F250 here with the 300 in it. We put a new head on it because of a couple burnt valves. While it was apart, we had the injectors cleaned and tested and found a couple bad ones. Replaced those, put her all back together and now it will not run. It will gladly start on ether, but otherwise no go. Some poking and prodding reveals that there is no fuel in the cylinders. I'm pulling my hair out trying to figure this out.
thanks in advance.
Nate

All the injectors should have 1 red wire. Make sure that wire is hot whenever the key is in the RUN or START position. If not, diagnose the EEC relay & brown fusible link. If they're both good, diagnose the ignition switch.
The other wire (Tan/Red or Tan/Org) should be hot when the engine isn't turning and switch to ground intermittently when the engine IS turning. If not, diagnose the tan wires and the EEC.

unplugged one of the easy injectors to get to and read 3 volts on either side, fooled with the relay and got it up to battery voltage, but no pulse in the wire. there is one ground strap that didnt get hooked back up, going to have to try that
