I was wondering if any one could tell me where my fuel pressure regulator is located on my 1987 VW jetta. It is a 1.8 liter non 16 valve.

My 98 S10 2.2 2WD lost its drive belt with resultant loss of power steering. My son was driving and was only 3 miles or so from home, so drove it home. In the driveway, it was overheating but not horribly. I did not hear it running. Got new belt and it cranks but it will not start even with stsrter fluid. Have fuel pressure of 44-45 psi on the fuel rail. Compression is only 30-40 in front 3 cylinders, 90 in rear cylinder. Comp. improves to about 60 in front 3 after I add a few squirts of oilin the spark plug holes, rear cylinder stays 90-100. All valves & lifters working when I took off the valve cover. Can my timing be thrown by the belt loss, resulting in valve bend/damage? Ran well prior to this, no speedster but dependable. Just rebuilt my wifes jetta after bad timing belt caused valve damage and don't want to do it again on this one. I'm not great at evaluating compression readings, how do you tell if it's valves or rings leaking? Thanks for your help, this site is incredible!

1995 Jetta III GLS 2.0 - Oil Pressure Light keeps coming off and on. It may flicker or stay on for several minutes. Or not come on at all. Can someone tell me what the problem is and how to stop it. I'll take any help I can get.

I have a 1995 volkswagen jetta, that starts when it wants to. I have narrowed the problem down to the fuel pump isn't getting power, can someone tell me what controlls the power for the fuel pump/where should i look next. ( not a ground issue already checked that)

If the light seems "irrational" and not related to engine temperature or revs, it's probably the oil temp. sensor or sensor wire.

2002 VW Jetta Over Heating by bob_roonie

I Have a 2002 VW Jetta that is Overheating. I have changed the thermostat already but did not bother to check the water pump while I was already there (duh) but what i have noticed is that the fans do not come on when the temp reaches upwards of 190 degrees. But the fans do work when the AC compressor is on also when the car temp reaches its limit then the fans seem to kick in and work extra hard bringing the temps back down. I have a couple of ideas but would like anyone feed back. Thank you

The heater and the air doesn't work. There is no air of any kind coming thru the vents. I have checked the fuses All ok. I don't even hear the unit turn on.
Any suggestions.
 
thanks

Might be the blower motor?
Try giving it a power source and see if it works .
If it does work then it might be the selector switch on the dash.

Could it be the coolant temp. sensor being faulty?
It may be reading the temp incorrectly turning on the fans after the temp has reached a higher temp than the sensor registers it as?

Have you checked the oil level?
If low then the oil pressure may be comprised.
An oil pump that is intermittent may cause this alert.
That is, one that is starting to fail.
Check the oil pressure to see if it is up to spec.
A clogged oil filter may cause this as well. (Really clogged.)
Oil that is too thin in viscosity?
