If my fuel pump is ticking like a clock (sometimes) and I am having idle/start-up problems then should I assume that I need a new fuel pump? or is it shorting somewhere??

 

GO RED SOX!!!

Ok..I think through some real thought (damn its hard right now with all the Red Sox excitement) I may have an electric pump...right? BUT it only ticks when the car is idling ****ty. Maybe I'll replace the cap, rotor and wires just to see what happens.

Don't know much about EA71s or early EA81s, but here goes some ideas:

 

I was pretty sure that yours was an electric fuel pump... my '82 is. Noise would be coming from tank area. I am also assuming that your car has an ECU-controlled carburetor. There were at least 2 versions of carb on the EA81 that I have heard of, and they are a little different. But mine has 2 solenoids mounted near the starter area but forward on the engine, and these normally click as the ECU decides what changes need to be made to the carburetor. (They change air-flow through certain jets within carb, one for idle, one for off-idle.)

 

So clicking may be these.

 

Probably check normal tune-up stuff and vacuum leaks.

 

Please, any more knowledgeable people around?

My fuel pump and carb always tick. I just never notice it unless the idle is really low or the key is in the on position.
