problem starting when warm
im new to the golf game having only owned mine for under a week so forgive me if its a daft question but…….my car 1.8 8valve starts first time from cold then runs fine when driving but if i stop then try and start again straight away it wont fire up :? it turns over but wont properly start up.
it happened the first day i bought it after i had been for a spin i left it on the drive for a minute went inside to fetch something and then couldnt start it to move it after leaving it overnight though it started fine again the next morning this wasnt so much of a problem but i have just stalled it pulling in to the end of my street :redfaced: and i have had to leave the car there as it wouldnt start :dontknow: im going to leave it for a bit to cool down and then go and try again
any of you experts know what could be wrong before i go and get robbed blind at my local garage?
thanks and any info much appreicated

mine is an auto and it's a common fault, on them at least.
I had a new starter from GSF, never had a problem since.

just search for HOT STARTING and loads should come up
it's all to do with your fuel system as it might lose preasure, the metering head might need cleans, the thermo time switch might be broke, leaking injectors the list is endless
its a process of illimination, there are tests in the haynes for the TTS and CSV so i'd start with them
but have a good search and if those don't help then you can always as

just an update i have had my car in the garage for the last few weeks and they thought it was the accumulator but that didnt fix it and then tried the cold start valve/injector and they think that has cracked it,wastn a cheap process but at least i acn drive it around now
Hi
sorry but i cant understand what the cold start valve/injector has got to do with warm starting - The TTS (thermo-time-switch)stops it operating above 35 deg
please advise if i am wrong
thanks

i had the bits done as mentioned above and at first it seemed to work fine i drove the 5 miles home,stopped then started it again went to pick a mate up,stopped started it again and then went to a shop for 5 minutes came out and it wouldnt start so it looks like i have payed just shy of £400 for no solution :roll:
whats next on the list to try?
any help much appreciated i just want to get it running properly so im not scared to drive it

It could be a few things, but it really does sound like your losing your fuel pressure which will cause the fuel in the lines to vaporize & in turn the vaporised fuel will not open a mech injector
Fuel under pressure eg 3 bar has a higher point of vaporising.
there is a tremendous heat in that area on the mk1 because the inlet & exhaust manifold are located on the same side of the head with the injectors right in the middle of the heat source
non-return-valve after fuel pump £20 , my money is on this
fuel accum £150 ish
meterhead - second hand
fuel leak
or just fuel vapour escaping
Next time it doesnt start , floor the accelarotr pedal & turn it over for a min with out stopping & it should start - but prob not wise to do this if its a ignition prob - pull a injector next time its not starting & see if there is fuel .
hope some of that makes sense , I've rushed it

ps the non-return-valve might just be stuck open & only need the dirt disloged its only a 3mm bore approx , its bolted straight onto the fuel pump.

i think im going to buy a non return valve and get a mechanic mate to fit it and see how that goes before taking it back and getting robbed blind again,will i have a problem getting just the non return valve on its own or will i need to buy a full pump and valve?

i had a non return valve after the pump fitted by a mate of mine aswell as a new pipe that connects it and again it seemed to of fixed the problem for a while and i have been out in it a few times without any trouble BUT i have just taken it on a drive (3miles) and left it outside my girlfriends house for around 2 hours and went out to drive home and it wouldnt start im still there now leaving it for a bit before i try again so i dont flood it/flatten the battery
so now the list of things i have done are as follows
new accumulator
new 5th injector/cold start valve
new non return valve after fuel pump+new hose and fitting
whats next on the list then chaps? im slowly running out of patience and i am desperate to get a good few weeks out of the beast before the cold weather sets in once more
edit- i am now home i left it another 20mins and it started fine and drove the mile home

I have also had some more hot starting problems, but since I stopped using supermarket fuel aprrox 4 weeks ago I haven't had any issues.
What fuel are you using?
