1994 E-320 Coupe - Engine Won't Start

Car started fine this morning, but I noticed the gas gauge was on "empty," even though the car should have had at least a half tank. So I turned the car off, and immediately attempted a re-start. The battery light and engine lights come on, but the engine wouldn't turn over. I checked the fuses under the hood, which all looked okay. I would appreciate any help!

    Thank you for the responses. I found the answer through another posting. I simply disconnected the battery and cleaned all of the fuse connections with DW40...and the car started! I am now going to change out the old Aluminum fuses with new (copper?) ones. The only problem now is that since I disconnected the battery, the stereo is requiring me to imput a "code". I have no idea what the code is, so the stereo will not operate now.

That is a security code you have to enter into the head unit when the power is disconnected. It should be in your owner's manual leather case. there is a clear plastic card holder that the card is in when the car is new. You enter the code and then hit the * symbol. after you enter the code wrong 3 times it goes into wait mode and there is a process you have to do to get it out of wait mode. so if you find the card and you enter the number 2 times and the unit does not start working do not enter it a 3rd time. if you can,t find the card call the dealership with the v.i.n. and they will give you the code(you may have to prove ownership by going there and showing you i.d.). The other possibility is is that the radio has been replaced but the installer forgot to put the new code card in the owner.s manual. In that event you will have to remove the radio and get the serial number off the case. with regards to your starting issue-I have seen on several occasions the starter not work or intermittently work with a fuse issue. I know that the starter receives it's power from the brake lamp fuse on 93 and 94 model year and some 95. I believe it is fuse 8 in the engine compartment. Make sure you put the right amperage fuse in and also that the correct wattage bulbs are in the tail lens assemblies. these type of strip fuses can blow just at the tip and make intermittent contact. I was going to talk about this in the original posting but I didn't want to lead you down the wrong path so I assume your vehicle did not crank at all. Good luck I hope I have been helpful

A ball acher, but check the starter solenoid Relay, by interchanging with another LIKE TYPE Relay, then if no joy, proceed to unfasten and clean ALL main line Power to... and Ground to... connections.Regards,DT

    Contact a Dealership and they can ID the Vehicle from the VIN # and then X reference the unit for a Code. Or the Manufacturer with the Unit Serial # and the same should happen.

Dash gas gauge stops showing proper gas level once it hits half a tank. Then gauge will fluctuate between empty (light will come on), full and anywhere in between but seems fine from full tank to half


If the trouble with the gauge started after you worked on it then you likely damaged or created a restriction to the movement of the sending unit. You will have to remove the tank and double-check your work.

Wont start


Sounds like a wiring problem at the gas tank.
I would check for voltage and ground for the fuel pump and the sending unit for the gauge.

I have fuel in gas tank-after shutting off will not start unless I put gas into fuel tank. Is it a fuel filter issue. or?


Just a question. Do you run your car on empty. If so that could be your problem with an empty tank you are sucking all the dirt through the filter and making it plug up. It is better to keep your tank above half full and does not cost any more than to run on empty. All mechanics will tell you to always keep your tank above half full.

Gas gauge is not reading correctly. Shows a full


the problem is caused by a defective gas gauge sending unit, this part is located inside the gas tank, you must remove the gas tank to replace it.

We just got a 1988 Porsche and filled with 1/2 tank, there was what seemed like overflow happening - Any idea what may be the problem.


fuel tank vent could be blocked by mud/pebbles etc, not letting the gas fumes escape while your adding fuel making it overflow, check underneath the car near the fuel tank .. something to start with..

Fuel gauge not working on 2005 ford mustang


Sending unit is in gas tank. usually as an assembly with the electric pump. These aren't cheap either, If you know a mechanic you can trust ask him how much to install a new one, I can get them wholesale for less than two hundred dollars, but of course retail probably more like 250.00 Hope this helps you!
