L-Jet: Over My Head, Bad ECU, car's back on the road. Options

[Mike Sanford]

I'm a little above my skill set playing with this stuff.

Took the wife out yardsale-ing Saturday morning. This is Tucson, maybe 85 degrees at 8am. Drove two blocks from home, stopped at one. Drove another 5 blocks, car acted as if it ran out of gas. Gas tank is full. Key on, pulled fuel line off of rail and opened air flow meter, squirts fuel. Pulled injector out of a cylinder, moved air flow meter, no fuel.

Shoved my analog voltmeter into injector plug, no sign of a signal at the injector.

Played on the internet looking up l-jet trouble shooting, decided to start with checking the relay because it seemed less intimidating. From what I'm seeing there should be voltage between 88a, 88b, 88c, and 88z and 85 (the ground). I have voltage everywhere except 88c. Come back inside, back on the internet, 88c looks like it powers the auxilary air valve. Would this cause the whole system to shut down? Is there something else I should be checking?

Thanks,
Mike

That last step verifies that the resistor pack is hooked up and is showing continuity. Pull each injector out, but leave the fuel hose connector as well as the electrical connector. Obtain a length of wire and turn the ignition key to the "ON" position. With this length of wire, tie one side to the negative side of the battery. The other side of this wire, touch pin 14 on the ECU connector. You should have a fuel injector spraying fuel like crazy. Do this for pins 14,15,32,and 33. Make sure the injectors click and you see a spray of fuel.

No smoking for this test procedure. (IMG:style_emoticons/default/blowup.gif)

After that test, check the resistance from pin 13 to pin 5
