Question about 1987 Volkswagen Jetta

2 Answers

My 2001 jetta has problems starting when I stop for a short time (1-7 minutes) it starts after a moment but I smell lots of fuel and i have to step on the throttle(3-4K RPM) to get it cleared out and idling right again. only does this when it's warmed up.

    Why would this fuel pressure regulator work when engine is cold but have problems when engine is warm? It used to only do this once in a while but now it's almost every time i start after a quick stop in the store.

    I was told that the fuel pump regulator could be bad but why would it start fine cold but have problems starting after being off for a few minutes.

    it's a 2001 Jetta GL, with a 4 Cyl 2.0 L engine.

    OK, this is a fuel pressure regulator issue. the diaphragm has ruptured. you can confirm by removing the vacuum hose from the regulator.check for fuel in the vacuum line. Replace the fuel pressure
    regulator with a new brand if fuel is present in the line. this faulty pressure regulator is basically flooding the injection system.

    I would also advise a few preventive maintenance inspections as well while you are replacing the pressure regulator. I suggest inspecting the Evaporative Emission (EVAP) canister purge regulator valve (N80) on air cleaner housing.Make sure this valve is operating, you should get a trouble code if this is faulty but, it is good rule to inspect the wiring in the valve. Next, i would inspect the injector seals for cracks as well. make sure the injectors are not leaking around the seal area.replace any injector that may be fouled.

It sounds like the fuel pressure regulator has failed.

Crank but No Start


No easy fix. Heck of a time of the year for the car to act up.

96 tahoe . It will not crank up unless I pour gas into the throttle body . Once it cranks it will run untill I shut it off but want crank by itself . Why


First, lets be clear with terms. To crank is to turn the engine over, you can do this manually with a wrench on many vehicles. It requires no spark or air. To turn over or to fire is when you achieve combustion. Example: You could pull the spark plugs on a vehicle and turn the key and it would crank, but it wouldn't fire or turn over.

Now it sounds to me like your vehicle is cranking but not firing unless you pour gas in it. My first thoughts are fuel system. I'm assuming it can't be fuel pump because it runs once it fires. Perhaps the fuel pump isn't priming itself, or perhaps somehow air is getting in the line between the injector and fuel pump? Test the fuel pump first by turning the car from off to on (not starting, just on). You will usually hear a short buzzing noise coming from the engine bay that stops shortly afterwards, that's your fuel pump pressurizing the line. (Pro Tip: If you ever try to take your key from off to straight to start and the vehicle doesn't start on the first try, but does the second time no problem, try delaying at on for a moment before trying to start. This gives your fuel pump time to pressurize the line.) Assuming your fuel pump is charging the line, the next place to look would be at the path the fuel takes to the throttle body. When you crank it over and it doesn't start, are you getting any fuel? If you can't see where the fuel enters the system try smelling the exhaust while cranking without it firing, if it smells of fuel you're good and need to look at air flow and spark, if not it's a fuel issue.

Past that, I'll leave it to someone more experienced than myself, but that would be how I troubleshot my own vehicle.

First time I experienced this problem.. my 2003 TDI manual Jetta started losing power as I was driving up a hill. Had the accelerator all the way down and was still losing speed. Got better on and off...


Probably time to get the injector pump rebuilt, it's dumping too much fuel into the engine. Or, something is clogging the airway. (sound deadening foam, don't laugh, it happened on my Volvo turbo)

I have a 2001 nissan pathfinder 4w. The OBD system-readiness status: Says catalytic converters, NOT READY; oxygen sensors, NOT READY; evaporative system, NOT READY. So did not pass inspection, I was told...


You have to re-set the obd via using Nissan's approved drive-cycle which is;

1. Start the engine when the engine coolant

temperature gauge needle points to C. Allow

the engine to idle until the gauge needle

points between the C and H (normal operating

temperature).

2. Accelerate the vehicle to 55 MPH (88

km/h), then quickly release the accelerator

pedal completely and keep it released for at

least 6 seconds.

3. Quickly depress the accelerator pedal for a

moment, then drive the vehicle at a speed

of 53 to 60 MPH (86 to 96 km/h) for at least

5 minutes.

4. Stop the vehicle.

5. Accelerate the vehicle to 35 MPH (55 km/h)

and maintain the speed for 20 seconds.

6. Repeat steps 4 through 5 at least 3 times.

7. Accelerate the vehicle to 55 MPH (88 km/h)

and maintain the speed for at least 3 minutes.

8. Stop the vehicle and turn the engine off.

9. Repeat steps 1 through 8 at least one more

time.

If step 1 through 7 is interrupted, repeat the

preceding step. Any safe driving mode is acceptable

between steps. Do not stop the engine

until step 7 is completed. If you cannot or

do not want to perform the driving pattern, a
NISSAN dealer can conduct it for you.

Car won't start


Disconnect the air filter tube from the throttle body. have someone step on the gas pedal or simply open the throttle valve then try to check if you smell gas inside the intake manifold. if you do smell gas, then you have an ignition problem. check if the spark plugs are getting sparks.. a general mechanic can easily isolate the problem. Have it checked.
