Title: Assistance with a non-starting 75 2.5L
Post by: redwog on October 14, 2009, 02:08:21 PM
Hi,

I am new here (but a life long 2nd generation alfisto) and hope someone can help.

My mother's 89 75 2.5V6, Auto won't start.

Car turns over but no ignition. Believe it to be fuel delivery problem as the plugs are dry and more obviously a dry fuel line into the injector rail.

Before tearing out the main petrol pump (we have replaced the secondary one) I threw the multi-meter onto the (what I believe is) the wiring to the pump and I am getting no current/voltage through while the car is being kicked over.

I have gone through the relevant relays and checked them they seemed fine, we began replacing them anyway but to no avail.

I feel it is an electrical problem not a pump problem, but we can't find the source.

Do any of you belli alfisti have a suggestion?

Andrew

From memory, you can check if the fuel pump is working by jamming open the flappy thing in the AFM with a screwdriver or similar, and turning the ignition on.  You'll be able to hear the pump if it's working.

The other thought is that if it's an auto, and I know nothing about the 75 autos, maybe the transmission is telling the car that it's not in Park or Neutral?  Except then it wouldn't turn over would it?  Okay, scratch that thought.
