^^^^^^ nice, or i use my tire iron... whap, stop taking my gas. "badguy": ok

LOL

 

We had some individuals around here stealing gas, one night they dropped a receipt for 2 gas cans bought at a local store, to bad for them it was a debit card receipt...........lol.....i think 5 gallons of gas woulda been cheaper than what they got.

 

no one stole the gas well then i guess its just me the gas tank thing makes sense but i dont know it used to do good no matter what but i dont know.........

 

The Chrysler fuel tank sensors are very sensitive to sulfur in the gasoline,
and go 'wild' when affected this way.

The gas gauge needle will begin wandering around and not show the correct level.

A few years ago Shell gasoline used a new "Bronze" additive that caused Chrysler fuel tank sensors to malfunction too.

In many cases this can be repaired by using 3-4 bottles of fuel injector cleaner over 4 tanks, but in the worse cases the sendor has to be replaced.

The higher sulfur content of diesel fuel in the USA causes most mid 1990s Cummins Ram fuel gauges to malfunction sooner or later too. It is very common.

If your MPG is really bad
the most likely parts to suspect first are the front oxygen sensors,
and the second most likely are stuck open fuel injectors.
High sulfur in fuel can also 'poison' O2 sensors.

 

thanks that the most useful info ive recieved, are those sensors hard and expensive to replace....and how do you know if the injectors are stuck open is there any way to check it.....

 

If you listen with one of those $8 'mechanic's stethoscopes' to each injector you might be able to hear which one might be malfunctioning.

For the money involved,
if I were you,
I would go to a Napa Auto Parts store and buy one of those 2-bottle kits of Cleen fuel injector cleaner. Put 2 bottles in your next tank of gasoline. For about $12 there is at least a chance that it may fix your gas gauge - and perhaps the injectors.

If the truck seems to run better after that tank of gasoline, go ahead and buy a different cleaner and put two bottles in the next couple tanks of gasoline.

Yamaha Ring Free ($9) from boat stores, and Chevron Techron ($7) are also good cleaners.
What one cleaner can't dissolve perhaps another can.


To check the O2 sensor you need a diagnostic OBD-II scanner. You might be able to leave a deposit and 'borrow' one at the Autozone stores.

Unless you are one of the unlucky ones on certain Ram model years,
you can read your trouble codes from the OBD-II or OBD-I computer
by turning the ignition key on/off three times and then leaving it in the on position.
Depending on the model year your Ram will either blink out the number of the codes using the 'check Engine' light - on the code will show up in the digital trip odometer display.

cool ill try those couple of things my truck is 01 sport with the 5.9L. one other thing, my throttle pedal is really loose and has a lot of play in it do you think that could be problem...

 

I had a vacuum leak that cut my mpg by a ton. Nothing on the order of 70 miles/.5 tank though. I always thought you got more out of the top half becuase the sender is not capable of reading to the extreme top of the tank. This and the fact that when you fill up you are also filling the fill hose.

 

where was your vaccum leak.....

 

I had a vacuum leak on a Jeep wrangler that made it burn 18 gallons in 100 miles. My leak was on the intake manifold that had a small crack in it. Took a while to find it, but I could barely keep it running when it was leaking. I found mine by spraying carb cleaner around spots until the fluid sealed out air and the engine ran smooth. Brother had a Ram with a cracked rubber hose from the manifold, can't remember which one though.
