2000 vw golf aqy engine, starting from cold is a real nightmare its seems as if there is no fuel getting to the engine. when it dose start if it dosen't run the battery flat first. it dosen't seem to have a choke active, the revs are at the first mark below No 1 on the rev counter. I have changed the ht leads and the coil pack has been tested. please help driving me mad. thanks

If it aftermarket, remove it.

spark plus and high tension wire need to replace

okay start hear turn key three times in a row there should here the fule pump prime ie a whizing noise you may not here this so now check the dash look for engine light it might flash if it dose it might be a code this is stored in the computer in your car .now this is where it gets tricky you need a code reader.but now what is the fact the year of the car and is it flueinjected tbi or carb and what year im not saying im a expert there a lot to go over start with check your manule then all ie oil coolent the right way by the book''''''I think it:is a seneser oil or coolent if the vw golf is 82 or newer but it dose matter what country the is in .in germany from 1975 the vw rabbit was a golf so it would help to know but find vw dealer there not cheep but they know golf I will say this if you smell petrol do not srart the car look for a leak if you find one fix it now dont wait it will cause a fire

CHANGE SPARK PLUGS CHANGE FUEL FILTER.SOUND LIKE VECHICLE NOT GETTING ENOUGH FUEL TO COLD CRANK NEED RICH MIXTURE TO COLD CRANK.

There are devices in the Bosch CIS-E system not functioning that may need replaced. Most commonly it would be the thermo-time switch. This switch is also a sensor telling the ECU whether your engine is cold or hot so it would compensate fuel delivery depending on temperature. An auxiliary air regulator also opens (more air) or closes (less air) dependent from the thermo-time switch signals. It's basically telling the ECU when it's a cold morning to supply a richer air/fuel mixture or not to when it's at operating temperature. There is also a cold start valve (fifth fuel injector) that could be sticking or leaking or simply not supplying fuel during cold start up. Again, this has a higher level of understanding and special VW tools to diagnose your fuel injection problem that should be left to a VW tech to work on. It could be dangerous because fuel is involved, a single spark from static electricity could ruin your day.

the passat uses coil packs one for each cylinder and the 2002 golf uses one coil pack that fires all cylinder and also not the same engine in 2002. now the 2000 vw golf with the 1.8 engine uses the same coils,so if its a 2000 vw golf with a 1.8 engine then yes you can use them they are exactly the same, hope this helps.

Probably the starter needs to be replaced. If it was the battery, you would have more problems cold than hot.

It sounds like the hydraulic lifters are bleeding down after sitting for a while... there are ball checks which are supposed to prevent this... Try using a good engine flush (a product that frees sticky lifters) and replace the oil with a good synthetic... Hope this helps...;-)

This is a common occurance on vw's, you need to check for vacuum hose leaks, this is the cause.
Volkswagen engines rely heavily on vacuum and if there is one cut hose, or one small leak, your car will run like this.
If you can keep it running with the hood up, start listening for vacuum leaks around your hoses on both sides.
Most vacuum leaks occur near the front of the engine bay.

Have you checked the Throtle position sensor it could be sticking when its cold, or the fuel pump could be going out on it the float might stick.
