Sounds like a bad fuel sensor or bad connections both are in the tank

Hello, has anyone had a fuel guage problem where the guage just goes from empty to full whilst driving along, its on a 2005 308 cdi sprinter, any solutions would be appreciated thanks brett


the fuel gauge works on an electric pulse. if it is unplugged it will go to empty if it is plugged i it will go up as fare as the tank is full. if it goes higher then the known fuel lvl. you have a bad gauge if it goes up and down when you know it is full you have a bad connection

1996 jeep wont stay started and oil pressure gauge goes up and down


hot or cold engine , or both.?
the oil pressure will be in direct ratio to engine rpm. slow low, fast high
due to the oil pump connection to engine crankshaft.

stalls.: can be caused by 50 things, or just 4 in physics.
the EGR valve (if you have one, no engine stated)
can stick open and stall any engine, and in fact LOVES to. clean it.
1: list 12vdc to EFI. (spark and fuel brain) dash lights dim?
2: lost compression hot, ? compression tests.
3: lost spark, do spark tests. and timing, checks.
4: bad fueling, too much if floods, and misfires and stalls.
too little fuel, it starves and dies.

the 1 free test, is can you save the stall with a fast right foot.

we do the tests. avoiding those 50 guesses....
each tests are simple and the tools dirt cheap .

My vehicle stopped dead at set of lights and would not start, called RACQ he installed new battery $165 Stated that was problem, drove less than 1/2 kilometre down road, felt the vehicle ****. Continued...


Sounds like you have a fuel issue. It could be a fuel pump cutting in and out. It could be fuel pressure regulator, or an injector not spraying correct. I think it's time to find an honest educated repairman.

1999 GMC Seirra fuel gauge and speed odometer stopped working


Yes, trace the wires fromt he high beam indicator light to ground.

Check for shorts in the wiring harness. This requires undoing the conduit, though which maybe should be left to an auto electric technician..

Also, if there is a short, it can be detected using an inductive ammeter around the positive or negative wire leading to the battery.

If it is above 0.2A then the system has a short somewhere.

I have a problem with my 1995 Merc c220, the fuel


Modern plastics seem to exude something that collects on all the surfaces inside the instrument clusters of many cars. When it settles on the pointers of instruments like the speedo and fuel gauge it produces the effect you mention, sticking the pointer to the rest stop until the meter has enough oomph to pull it free or you go over a bump.
If you have a good magnifying glass you should be able to see what's creating the problem by looking at the ends of the pointers..Actually, just condensation can do the same thing but it's not so sticky and you'd see a mist in the perspex cover too. Since the speedo and fuel gauge control comes from completely different areas these are the only thing I can think of that may link the two things. A couple of extractor hooks from MB would allow you to pull the instrument assembly from the dash. Disconnect the battery if you go this far as it's so easy to short something behind the instruments. Then it's a question of unclipping the two connectors at the back, pulling the cluster free, and unclipping the perspex cover. The procedure's well covered in the Haynes manual.

Cavalier dies


you need to find the fuel pressure release around the fuel rail press the little tab when the car dies. If there is no fuel coming out from that point, your fuel pump is going.
