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

Everything sounds right. You will not have voltage at pin 88c unless the key is turned to the "start" position or the engine is running. 88c is tied to 88d which supplies power to the fuel pump. Also, the air flow meter does not send a signal to fire the fuel injectors.

Is the car still in its failed no start mode?
