Re: question??????

For the pump to prime the key has to be on and the kill switch has to be set to run instead of off..

Re: question??????

sorry my bad, the kill switch is the red button right? so when you turn it on, the fuel pump starts to prime, but right now is not priming.

Re: question??????

Ok so I would narrow it down to the pump or an electrical problem going to the pump. You need to see if it is getting power, if you checked the fuses and they are good that is about all you can do if you don't have a meter to check the feed.

EDIT: and that's just a guess I never worked on my fuel pump when I had my 929, just cars with fuel pump problems.

Re: question??????

yeah i've checked the feed to the pump using a voltimeter and when i turn on the kill switch it reads bout .02 volts, so the manual says that if there should be voltage for a few secs, if theres is replace the fuel pump, but the thing is that it doesnt says how many volts should i get from that connector.

Re: question??????

Had the same prob with my 929. I replaced a clip on and the wire for the kill swith got separated. Take the kill switch off and look at the wires. It worked for me
