Having a weird issue with the Maverick after having converted it to EFI.
If I have the air flow meter connected, the car will not run, it'll crank over but will not run.
If I disconnect the AFM, the car runs, idles, revs. Bit rich but with nothing to tell the ecu how much air is coming in I assume it just richens it way the hell up.
Now, when I pull the AFM and test it(hook up to power source and blow air onto the exposed sensor, I get the readings I should. Same if I have it connected with the ignition on(not running) and the ECUtalk cable connected. I can blow on the sensor and see the voltage change as it should on the display.
TPS is fine and crank angle sensor in dizzy seems to be fine.
I was almost sure it was the afm and was preparing to fork out a lot of cash for a new one, until I hooked up the test leads and checked it, but now I'm not sure what to do.
With the AFM connected but the engine not starting I get no ecu codes, with it disconnected I just get the AFM disconnected code, so if it was a short or a connector in the wrong socket or something I'd expect to see other codes?
