Car Forum / Volvo Cars / June 2004Occasionally won't start !
I have a '99 V70 SE, 20 valve, automatic. Just occasionally (twice now) I turn the key and ... nothing happens. I hear the click of the fuel pump relay and the starter relay, but the starter doesn't jump into life. I've tried to be methodical about a diagnosis. Like, shift the gearstick back and forth in case it's the Park/Neutral interlock. That worked once, or seemed to, although since the starter relay clicks it's unlikely to be the cause. Then yesterday, I tried that again and nothing. Then I took out the relays and gave them a whack, just for luck. No change. Then pull and shake the connections along the way to the starter motor. No luck. Then 2 minutes later - it's working again. Anyone know if this is a "feature"? Common enough that there's a known fix? I know if I take it to the dealer, they'll mess about with it for 3 hours, replace all the relays, charge me $200 and tell me they can't find the fault.

The "sealed" wire connectors at the battery can corrode under the insulation. good luck chuck petterson 73ES Check the resistance in the starter/battery cable, and the battery/ground cable with an ohm meter. Then after cleaning and assuring proper battery and ground connections hopefully it will be OK. That was my problem anyway. Hope this helps. Rich > I have a '99 V70 SE, 20 valve, automatic.

A quick wiggle of the wires to the starter fixed it. One of them felt quite flimsy and loose. I'm going to take the cables off, check the connections and hopefully that's the end of the story. Cheers Chris OK, a little while fiddling with things and I think I have it solved. There's a flimsy little yellow wire that slips onto a little spade lug on what looks to me like the starter motor solenoid. This was loose and wobbled about quite a lot. I tightened it up by squeezing the female spade with long-nose plyers. The effect of removing the wire is the same as the sporadic no-start symptom. And the effect can be duplicated by reconnecting the wire but putting the car in R or D before starting. Without consulting a wiring diagram I can't be 100% sure, but I'm guessing that the yellow wire belongs to the park/neutral interlock. Connection tightened and fingers crossed... Chris |
