Question about 1996 Volkswagen Jetta

1 Answer

I have a 1996 Jetta 2.0L. Especially when it rains, it won't start.

I have checked the signal at the fuel pump relay. Sometimes it is not there (then the car wont start). Where does this signal originate from?

SOURCE: Fuel Pump Relay

Obviously, you can jump the relay but it is dangerous on an extended basis. You'd have pressure in the lines when you don't want it there. Replace the relay if it is defective.

If you have other issues, you can check the pump back to the tank by going on the business end of the relay and looking for resistance at the pump to ground. If it is open, the pump or the harness is bad...GMs have harness issues...not Fords.

Check your fuel pressure to ensure proper pressure to the block, also did you replace the fuel filter.

On a side note: 3 things a automobile needs to run

AIR-make sure you have a clean air filter and your MAF (mass air flow sensor is plugged in) if you pulled your breather to innspect anything, there is a possibility that it came unplugged or you unpluged it and forgot to hook it back up, a car wont start without it being plugged in if equiped

SPARK-Make sure your car has juice to the plugs, if the plug doesnt fire the car wont run, if you have to pull each plug and ground them to the engine block to see if they arch. If not trace the problem down (if you changed the fuel pump you have some mechanical skill and should be able to troubleshoot a spark issue)

FUEL-Check for proper pressure, dirty fuel filter(s) and if your system has a return line, make sure your hoses didnt get crossed cause this will damage the engine and regulator.

Hope this helps Thanks for using Fixya.com

SOURCE: Have 2000 VW Jetta, turning signal stops working

I pulled my switch out of the dash and sprayed it with contact cleaner. Air dry and put back in. 2 years without a problem. If you're not electrical savy, I'm pretty sure there was a recall on that, and it should be replaced for free.

No power to the fuel pump on a 1996 buick century


check for a problem fuel pressure regulator
most are wired to the ECM which is connected to the relay for the pump
it works like this
with low / no fuel pressure the regulator completes a circuit to the ECM
that signal is then sent to a relay to start the pump
when full pressure is reached , the regulator signals the ECM and the relay is turned off hence the pump is not continually running when pressure is not required

Why won't my car start? It was running last night.


Try start the car again when it is completely dry, if it starts the rain may be short circuiting something on the loom in the engine bay.

If it still wont start,

will it turn over? (car tries to start)
- If it wont turn over the battery would be dead

- If it turns over but wont burst into life then we can go from there ^_^

Need to locate fuel pump on 96 jetta


1996 Volkswagen Jetta 2.0L SFI 4cyl

On a Digifant fuel system, the fuel pump is mounted in a reservoir under the rear of the vehicle. The fuel filter is also in this area. The reservoir holds one liter of fuel and is supplied by a small transfer pump in the tank. The transfer pump can be replaced separately even though they are installed and removed as a unit.

The Motronic system uses two fuel pumps. The first is a small transfer pump to get the fuel out of the tank and the second boosts the fuel pressure to the necessary amount. The transfer pump is located inside the tank and the main pressure pump can be found under the vehicle. This transfer pump is located under the rear seat and is part of the fuel gauge sending unit. The main fuel pump can be found in the reservoir in front of the rear axle beam. There is a check valve inside this pump to maintain pressure in the lines, especially on hot days, to avoid vapor lock. The fuel filter is mounted to the side of the reservoir. This filter has no specified replacement interval and should be good for the entire service life of the vehicle. Whenever the ignition key is in the on position, the pump should run for at least two (2) seconds to pressurize the fuel lines. If the Engine Control Unit (ECM) does not see a signal from the Hall Effect sensor in the distributor it will shut the pump off. If a Hall Effect signal is present, the pump will continue to run as long as a signal is detected. It is this Hall Effect signal that signals the ECM that the engine is rotating therefore indicating that fuel is needed. The pump is operated via a relay that is controlled by the ECM. This relay is located in the vehicles fuse panel. The main contacts of the relay can be jumped to run the pump during testing.

Good luck (rated this help).

95 Jetta stalls when I shift into 2nd


You either have bad plug wires or water got in the intake like billie said and is playing havic on your mass air flow sesor. Test the plug wires by squirting some water on them when the car is running (we are looking for like a spray bottle squirt not to much).
If nothing changes ( you will be able to tell the car will wana die or you will see them grounding out a bit) then you can try cleaning the mas, or just replacing it.
Also check your air filter while your in there as well might need to be replaced now :)

Good luck
