    I switched the glow plugs on 3 times then started the car up about 30 seconds later.

    have you replaced the glow plugs ? once running does not sound too bad tbh

    was that first start of the day ?

    does it take longer to start if you don't activate the glow plugs 2 or 3 times ?

    not replaced glow plugs yet. I heard there a nightmare. yes that was the first start of the day. I don't see a difference if I activate the glow plugs 2,3 times. how much do you think a garage would take to replace the glow plugs.

    Re: throttle body query saab 1.9 tid

    they are pretty simple to do just need to take your time and be patient

    spray around seats night before or few hrs with wd40

    gently try to crack them loose .............if they don't budge a bit more wd40

    once cracked slowly undo if you feel tension apply more wd40

    use the loosen/tighten method

    never had an issue with them

    as for a garage £10-£15 each labour but if you feel confident better to save money

    glow plug set of 4 NGK £40 Bosch £55ish Beru £40 ish

    does it start any easier once engine warm ?

    Re: throttle body query saab 1.9 tid

    ok as we need some where to start here, I think new glow plugs are the first thing and cheapest starting point given your above comment
    and bad glow plug can cause smoke, not saying its 100% related but once it starts ok if need be can move on

    do you feel confident in changing them ?

    so to refresh me once started it runs ok when at operating temperature ?

    what do you think the millage is ?

    in 2 minds whether to get you check the glow plug relay first although given the millage you wont go far wrong changing the glow plugs especially with the colder weather coming

    Re: throttle body query saab 1.9 tid

    following on from earlier pm

    when you crank the car, what rpm is the rev counter reading ? 200-250 would suggest the starter is turning at a healthy 2000-2500rpm,

    as for checking the solenoid and the starter turning we can confirm this so them tests pointless,

    if you have a clamp meter you can see what amps the starter is pulling a good starter should draw around 130-150A

    easy enough to check first option and will give a good indication tbh expect this to be ok, given the issue you also have with smoke which is what is throwing me off this idea I could be wrong though.

    what Voltage do you have on battery and what does it go down to whilst trying to start

    given you have glow plugs tbh would try these first
