back to my 242 again... 200 1980

posted by  someone claiming to be Anthony on  Sat Nov 25 12:02 CST 2000 [RELATED]

I posted a message before, but have done some more troubledhooting. Get ready this is a long one.

One 1980 242 w/b-21 and k-jetronic. Before replacing head gasket and reconstructing wiring harness, the car would start immediately every time regardless of outside temp. After doing head work and harness, car is difficult to start without messing with things. Here is what I found since the last time.

With the rubber intake bellows off, If I lifted the sensor flap just a hair while my brother cranked, it would start immediately. With the bellows on and not touching the flap, it wont start at all. This is with the cold start injector disconnected, but every one I have seen would start a little hard or at least sputter even without it hooked up. Next, I stood ready with a small battery and alligator clips ready to hook to the cold start injector. With my brother cranking the engine, as soon as I powered the injector the engine would fire. However, even after 20 seconds or more, it would stall as soon as I disconnected the injector. Was the engine running on just the cold start injector? I have checked the fuel control unit and I get a lot of fuel from the injectors by manually lifting the plate and the spray pattern is pretty decent. I only have to lift the plate a little bit and I get fuel. the level varies smoothly as the plate is lifted higher.

Why does the car take so long to activate the airflow sensor? It will run without the cold start injector, but it takes a long time to start. I sure cant jump the injector for half a minute and keep my foot on the pedal.

thanks...
