Question about 1986 Volkswagen GTI

1 Answer

Car won't stay running.

I replaced the water pump and had to replace the timing belt. The car ran before I replaced both, now I cannot get it to stay running. Marked the gears on the crank pulley. The car turns over and catches but will not stay running. I have to put the gas pedal to the floor or pump the gas to get it to catch. Never had to do this before. Do I have to re do the timing? If so how do I check to make sure the timing is right?

The gti is a 1.8L? Guessing it is you'll have to check all 3 sprockets at top dead center. With the timing belt upper cover removed the mark on the back of the cam sprocket should align with the upper surface of the cylinder head. At this point if the timing is correct the mark on the crank pulley and intermediate shaft should align. You can also check the inspection hole in the transmission as the mark of the flywheel should align with the arrow in the housing. I have a big feeling your timing of your intermidiate shaft is off. If you follow the cylinder 1 wire to the distributor cap then remove the cap the rotor on top dead center should be pretty much aligned pointing to part of the cap where wire 1 is. Sounds like bad timing. If it's off a little you can loosen the distributor bolt and turn the assembly adjusting the electric timing but this gets much more complex as you can over advance the engine and cause damage as well.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

Dodge stratus 6 cyl 2005 not sure of engine size. I only want to advise my daughter on what she should do about replacing her water pump. Car seemed to be running fine but was losing coolant. Car was found...


It is common practice to replace the water pump when replacing the water pump also. If the timing belt has recently been replaced than it would not be necessary to replace it again. If the belt is original than it makes perfect sense to replace it when the water pump is replaced as the timing belt will need to be removed in order to replace the water pump. There is no additional labor coast just the additional parts cost of the timing belt.

When it is done you shouldn't have to worry about it for the next 100,000 miles or so.

If you don't replace it when you have the water pump replaced than down the road when the timing belt is due for service you will have to pay for all the labor costs again to replace the water pump.

I have a 2005 Audi A6 with @ 100,000 miles on it. My dealer is recommending that I replace the timimg belt and the quote for the job is $1500 to $2000 which will include a new water pump. There is...


On these vehicles, the timing belt is recommended at 90K!! I recommend replacing the T-belt and water pump at the same time. The water pump is timing belt driven, and if it fails, you would be paying for another Timing belt service!! YOU WILL NOT experience drive-ability issues because the belt is aged or has not been serviced at its recommended intervals. Instead, if the belt fails, your engine will fail, and will require replacement or rebuilt ($3500+ job). Find a less expensive reliable shop thats experienced in EURO vehicles, and stay away from the dealer!!

well that is how I always sell a timing belt job also. The water pump is driven by the timing belt and it is very labor intensive to replace. I always replace the water pump also because you have to remove the timing belt to replace. I have had people refuse the water pump, and have to spend the same labor dollars a few months later when the pump went out. Even if not leaking it is always good insurance to replace the pump with the timing belt but is not a must just good idea.

Timing belt replacement


From what you're describing here, the timing belt wasn't installed properly to it's timing marks from the start. You mentioned it ran rough when you got the car back. That immediately told me the timing marks were not correctly lined up. If the belt wasn't tensioned correctly, the belt will gradually start retarding itself to the point of it not running. You did mention that as well already too. In other words, the belt slowly got looser and looser until the valves were not opening/closing at the correct time and eventually the piston hit the valve due to the lack of the tension of the belt not being correct. I really fail to beleive that the tensioner went out "all of a sudden" especially right after the water pump was installed. The reason it is recommended that the timing belt be replaced at the time of the water pump is antifreeze/coolant will SLOWLY deteriorate the belt causing premature wear. This doesn't happen in a week either, this take a long time to happen. My professional opinion is the timing belt was incorrectly re-installed when the water pump was replaced. I've been in the auto repair business for a very long time (28 years) and I have seen this very thing happen when the customer tries to replace the timing belt or water pump themselves especially when there was a lack of experience.
