Check gage light comes on, then steering locks, then dies...any ideas? I then let it sit for a few min and restart it...then it runs. Just started today, happened twice...


When the CHECK GAGE turn on illuminates when the engine coolant temperature is high, the engine oilpressure is low or the fuel gauge is at or near empty.

Check your Service Manual for this and other details.

Hope help with this (remember rated this help).

Falls on Its face 3-5 min of driving


check the vacuum lines on the engine.sometimes these will crack or develop a small hole or break and it will **** too much air in the engine causing it to act that way.

2003 Dodge Ram 1500 Fuel Gauge drops to empty while driving.


I have the same problem on my 2003 Dodge Ram 2500 5.7 Hemi. Also the gauge is sometimesslow to register after filling. Maybe 5 minutes.My neighbor has the same poblem with his 1999 Durango? I think this is a job for a recall.

I have a 94 chevy s10 and my gas reads empty while i drive.but when i shut off the truck the gauge moves to different readings.


Is......the problem--"the gas gage reads empty when there is fuel in the tank. OR, The gage moves when the key to turned off ?

If it's the first,
You will need to test the gage and through process of elimination, determin if the Sending unit inside the fuel tank has gone Bad.

If its the second ? - Electrical gauges will move when powered down. Normal

Testing the gauge may not be easy - just depends on your ability.
It is a simple 2-wire gauge circuit, when disconnect (usually need the fuel tank) the gage reads in one direction (either full or empty)
then when shorted-the gage reads in oppisite direction.

Of course you must select the correct wires or you may short out the wrong circuits!! Most GM vehicles use a purple wire & black wire.

A quick method I have used to check the in-take part of the gauge is this.
1st. know there is gas - 1/2 tank works best.
2nd driver's door open, key in run position, engine not running.
3rd gently lift up on the door then let if come back down, gently.
just enough to cause the gas to slosh around.
4th - keep an eye on the gas gage, a bad sending unit in the take will show up as a "twitchy" needle.

Of course, if the gage never leaves empty - sloshing won't work.
I have a known good sending unit I can plug into the vehicle and simulate different levels of fuel - if the gas gage works, I know the problem is in the tank.

Let us know.

Fuel gage


They get gumed up(more so if they have sat for awhile) other than pulling them out of the tank. the easyest thing to do is add some antiguming fuel additive to your gas. it takes some time. It will losen them up.

Fuel level sensor in tank bad????


Yes it is all one unit, and yes that is what the problem is. don't use aftermarket parts, use OEM, (Delco Remy) they are much better quality.
