For over 1 year I’ve had a problem with my 2001 Volvo S60 only giving a “click” when I attempt to start it. Often when I repeat multiple times, it DOES START, but more often than not, it doesn’t (at least right away).
I’ve replaced the battery, starter/solenoid and starter relay. Twice I’ve had it to the local Volvo dealer, and both times the mechanics said the problem was associated with “corrosion” on the solenoid blade. Once the mechanic just “wiggled” the connector, and the other time the blade was sanded to remove potential oxide/corrosion.
After replacing the starter/solenoid, it STILL didn’t start, so I replaced the wire leading from the fuse-box, thinking that “wiggling” the connector may have degraded the crimp on it.
Now the car won’t start AT ALL. I’ve tested the line from the fuse down to the wire to the solenoid, and the ECM only now gives a “pulse”, rather than turning ON while the ignition is turned to START. I’m thinking that some other input is telling the ECM to NOT CONTINUE CRANKING.
