Hi, I had a quick couple of questions for you guys. I am trying to help my mother out with her '77 240 that was running very badly and then died on her. I really dont know anything about K-jet so any advice would be greatly appreciated This car has spark and will run on ether. I connected a guage to the fuel line from the pump and saw 70-75 psi when cranking, yet no fuel exits then injectors when they are removed for examination. The fuel filter was replaced, then bypassed.

At this point I have a couple of theories and would like to narrow things down with your help. Is it ever likely that failure of the lambda control valve [is this what its called, funny thing like a d jet injector on the side of the fuel distributer] or its circuitry could result in a fuel distributer diaphram pressure such that no fuel at all gets to the injectors? I am thinking of looking at the pressure regulating circuit in the base of the distributer, but was also wondering if the control pressure regulator could be the culprit here. Itried to read up on the function of this part and it seemed to me that its use is primarily as an enrichment device when the car is cold. Yet, if the bimetal spring inside this device breaks or something could pump pressure be fed to the tof the control plunger leading to no plunger movement? Is this ever the case? Am I thinking about things correctly?

Any other ideas? I will try and make a T guage for testing as the book suggests, and maybe look at the centering of the throttle plate, but I hoped I could get a little more info first.

Thanks,

Jesse
