    Vehicle : Vectra Cdti 150

    Trim : Sri

    Engine : 1.9

    Year : 2004

    Mileage : 82000

    Default car will not start

    Hers one for you guys...vectra 1.9 cdti (150) on 54 reg. Tried to start the car today no joy, all i get is a couple of clicks from starter motor,will not even turn. Thought battery was dead so got booster cables on still no joy. Finally ended up bumping it off by being towed down the road 50 yards or so. Car running fine, took it to car spares shop tested everything all came back fine. parked it back on drive will not start again just the 2 clicks and now I get " F " on the display where it gives me the milage consumption.. Could it be the starter motor and why do I get a " F " in the multi display...any info would be appreciated as had nothing but problems since I bought the car

    Problem with the starter wouldn't put an F on the display.

    The F indicates canbus fault. I've had an F on the dash. Was driving along and all of a sudden EVERYTHING cut out. Turned out a rodent had been living in my engine whilst I'd been away one winter and chewing the loom and other such things like fuel hoses. Eventually a wire corroded and broke. I think it was a live feed to one of the computers so the computers couldn't communicate over canbus network.

    With mine, key to start position wouldn't even cause starter solenoid to click.

    You can test the starter quite easily and independently of everything else (except the battery of course and main battery feed to the starter). If you have a bit of cable you can put battery positive to the "S" terminal on the starter - make sure car not in gear!!! If it doesn't crank then either the starter is faulty, there is a problem with the battery or there is a problem with the main cable between the battery +ve terminal and the starter "B" terminal.

    Sounds like the battery is flat due to failed alternator.

    Check the voltage at the battery with and without the engine running. If it's less than 13 with the engine running, the alternator is f****d. Ideally should be 14.4 with all electrics turned off (with engine running)

    No crank situation so how can you check battery voltage with engine running?

    If battery was flat and alternator not working then surely bumping the car wouldn't help it to start and run fine for him to drive it to a place to be tested and drive it back? No complaint of power steering failure which is very common with alternator failure. Surely car would crank on jump leads even with a duff alternator and battery?

    Also how would flat battery explain the canbus fault? Or is F displayed for low voltage situations and other faults outside of OBD?

    same as above but also it could be the starter solenoid sticking.?

    Only a suggestion mate

    My alternator failed in similar circumstances. If the car starts with a bump, the voltage can be checked that way. My display showed "F" too. Low voltage can upset the canbus systems throwing up errors.

    It's an easy test too, even checking the voltage with the engine off (12v or above) would help diagnosis too

    You can get loads of canbus problems with low charge state.

    lol....Tony is probably right but obviously something between the alternator and/or the starter motor, first port of call would be check the battery voltage when at rest which as he said should be around 14.4 volts.

    Yes apparently reading thu the forums, the "f" can mean a multitude of things!

    So, on the basis that the battery voltage is very low (no crank and canbus faults symptoms), but the car worked fine (with PAS etc) with a bump start, the car must be running off the alternator charge but the battery is not charging. Or, the battery is charging but there is a parasitic drain whilst the car is parked.
