refusing to start in cold mornings

[sharki786]

My mk3 8v gti (agg engone code) is refusing to start again in the cold mornings. It cranks fine and keeps cranking for ages till the oil light flashes (wont fire up or start at all). Did it today at 2pm (not long ago) today morning i got in car at 5.30am and it just kept cranking didnt fire up (kept cranking for 5-10 seconds, no luck tried again then fired up after a good few seconds. Its been parked up all morning. I went to the car at 2pm and tried to start it but same again (cranked for 10 secs, no luck, tried again, no luck then tried again and it fired up straight away.
In the summer it fires up as soon as you turn the key. Battery is fine btw

Lazy Starter?

temp sensor is worth checking

Temp sensor is very likely. I had an 1.8 GL back in the day with the same problem and it turned out it was the coil. It had spark but it was very very weak. It always eventually started and never cut out on me.

Hahaha damn right after the amount i have spent on the mk4 and its not even on the road yet. Lolsss
Dont think its a lazy starter as in summer it started on the 1st turn of key.
Coil is a few months old aswel.

Anyone? Only happens in the cold. Never messed ne about in the summer mornings. Just last week when it was cold

[boneybradley]

coil, temp sensor, iffy hall sender wires (although this should throw a code up).

[sharki786]

Will check for codes when i get a chance. Coil is a few months old. Il check the temp and hall sensor. Thanks
