1975 beetle cylinder won't fire.

Asked by Elanmechanic Jun 11, 2016 at 08:03 AM about the 1975 Volkswagen Beetle

Question type: Maintenance & Repair

I can't figure this out!  The rear right cylinder is giving me trouble. The car will
run with the plug wire out of the distributer cap but when I plug it in it cuts out
and ends up quiting. I have changed all the plugs, wires, points, condenser,
coil and fuel injectors. It was running fine but recently started this trouble.
What else can I check?  Thanks, Roger.

Have you accidentally gotten the plug wires mixed up at the distributor cap? Pretty sure that there is no fuel injector on a 1975 VW Beetle.

Yes it is fuel injected and it has not been converted. I tried switching around the wires with no help. Of course the book I have is not as descriptive for wire placement as I would like.

So I think it is the fuel pump. It ran great then it quit. I turn on the key and no sound from the fuel pump. There isn't even any power to the connections on the fuel pump. Is it a sensor???
