Title: Cold Starts
Post by: drc12369 on 30 November 2012, 22:16

So its that time of year again and after leaving the car alone for 5 days  or so when i come to start it, it takes a few attempts and upto a minute or two to fire up. So what can i do to improve this? Im fitting new spark plugs Sunday (NGK BUR6ET) so what else can i do to help thats cheap and easy?

check dizzy cap if moisture is in there, same for cables

check engine temp sensor using an ohm meter (multimeter - 10£ one from b&q/homebase/halfords will do):

it's a dual sender, one goes to your instruments the other to ECU... if it's broken the engine would use a standard value, in cold weather that could cause too little petrol being injected...

if you got a diode test lamp or an oscilloscope (or a cheapish ebay DSO) check if the crank sensor is working when you crank the engine, although this would normally also give you trouble when it's warm.

Im doing the plugs tomorrow, if that doesnt help i might just do the ht leads and dissy cap. Does anybody know the vag part no for a 97 2.0 8v 1H AGG gti dissy cap?

May not be much help exactly but i've noticed with mine it won't start unless there's sufficient cranking speed, anything below par and it'll spin away no go.. suggest's battery has to be in top order/correct rating as a first port of call (my case) although other usual suspect areas all have a say in the matter probably.

or ECP with forum discount! :whistle:

No car likes standing for long periods as alarm/immobiliser will drain the battery.
If you know you are not going to use the car then disconnect the battery, its very quick and simple to connect up again.

And yes the battery should be in top condition for cold starts.
