SOURCE: can't get gas cap back on 1999 e320

Check the metal tabs on the gas cap they should be aligned with the little groves if there not the cap won't go on correctly or close all the way and you will get the engine light coming on. Happen to me and I used a pair of needle nose pliers to move the tabs back into place (wasnt easy) and then it worked fine...Hope this helps you.
P.S my cap got like that after I fueled the car and was in a hurry now I make sure everything lines up before I tighten it.

2013 Kia Optima. Fuel gauge shows 1/16th of a tank and the low fuel light is not on. Engine shut down. Out of gas. Add gas. Car starts up. What would cause the gauge to misread in this way?

most fuel gauge readings are not that accurate anyway so its out of fuel but not what the is guage reading. but the fuel level sensor in the tank may be at fault sound like its the prob but the instument pack should put the low fuel light on if its fitted on your vehicle spec but not always fitted even though the warning light is present hope this helps

93 ford thunderbird LX dies as if starving for gas after I start it

You may have cooked the fuel pump.
Cars today use a fuel pump in the gas tank. The pump uses gasoline for both lube and to help keep the pump cool. Anytime the tank is below 1/4 the pump is working harder and running hotter than normal. If you drove it for 2 hours low on fuel, the pump may have died.
I would check the fuel pump relay to make sure the pump is getting power, if it is not, you can bypass the relay to verify it is not a pump problem.

Low oil pressure warning

It sounds like the oil pressure sending unit is going bad. Sometime they're called oil pressure switches. That would be my first guess. Why its proportional to 1/4 segments of gas portions makes very little sense. Fuel level sending units work as semi circular resistance sweep. Not in segments the only thing that segments fuel protions are the lines on your instrument panel gauge. Anyhow check the fuel pressure switch.

Cant get gas into the gas tank, i can get about $3 at a time. I had it looked at there is nothing blocked

It happens to me if I let the fuel go under 1/4 tank. it can also set off the check engine light and then you have to drive about 50 miles for it to reset. If the fuel tank is low the emmissions build up in there and set of the click on the filling handle. As long as I keep the fuel over 1/4 of a tank it doesn;t happen..

Ireplaced both wheel speed sensors due to abs

I had a 2001 silverado 2500 h.d. with the same problems. I took it to a gear head and he found that the emergency brake cable was loose causing it to trigger the warning light on the dash. As far as the low fuel guage I took it back to the gear head and he found that the float in the gas tank was broken causing the low fuel light to come on. The float wasnt a big deal until I lost track of mileage and ran the tank dry.

Low fuel warning light has stoped working

If dash lamp blub checks out to be good, the fuel tank sender located in the fuel tank is what triggers the lamp and is most likely in need of replacement.
