    Mine does the same thing about the same time that the engine choked when i hit the gas pedal. It choked out two weeks ago and will not start at all. Replaced the fuel filter, no change. Poured small amount of gas in intake and the engine turned over. I'm wondering if the fuel pump / gage are on the same circut and something has come loose.

Mine wouldn't start if the temp was below freezing outside. Dealer tracked problem to after market alarm system that was installed to the main wiring harness. He de-installed the alarm system and replaced the wiring harness. Like magic that and 4 other incideous little problems disappeared.

Where is the anti slosh module in a 1988 mercury grand Marquis ?


Anti slosh module? I've never heard of that. If there is such a thing, it must be on the fuel level sending unit in the tank. It is usually the sending unit at fault when the gas gauge stops working.

Here's how to check if the problem is the sending unit or the gauge in the cluster: you will need a helper to watch the gas gauge needle. Pull the electrical connector apart at the tank, find the gas gauge wire. The power wire for the fuel pump is pink and black, and the ground for it is a black wire, so the fuel sender wire should be a different color. When you figure out which wire is for the gas gauge, turn the key to on, and take a jumper wire and ground the gas gauge wire to the frame. Have a helper watch the gas gauge needle when you ground the wire: the needle should move perceptibly. If it does, the gauge in the cluster is good, and the problem is with the sending unit in the tank. If grounding the wire does not make the needle jump, the problem may be the gauge in the cluster. Be sure that you have made a good contact with ground with the jumper wire.
There is a small match box size voltage regulator on the back of the cluster. This sends low voltage (about 5 volts) through the gas gauge and on to the wire going to the tank. When you ground this wire, it should cause the gauge needle to go either to full or to empty, but you should see the needle move. Remember, key on, then ground the wire. Any movement of the needle means the gas gauge is probably good, and the problem is the sending unit in the tank.

How can I get my gas gauge to work


There is a "balance" ball/gauge inside the gas tank.. Many times it gets stuck. If it is stuck, try to SHAKE THEentire car from the bumper while u r pumping gas... However, many times the "gauge ball" brakes and u have to drop the fuel tank:(

1970 Ford F100 Gas Gauge Not Working


It may be the sending unit in the tank that needs replacing. Here's how you can check: Turn the key on and disconnect the sender unit at the gas tank. Ground the sender unit's wire with a jumper wire from the truck's harness to ground. Watch the gauge. If the gauge on the dash is good, grounding the sender wire will cause the gauge needle to react and should move to full. This would indicate a new sending unit is required. If the gauge doesn't move when the sender unit is grounded, the gauge is bad and needs replacing. Pull the instrument cluster out to replace the gas gauge. Likely any old ford gas gauge might work-back then, there were not so many production changes.

I sounds like you have an electrical problem with the dashboard. It will have to be pulled and checked.

I had the same problem with the gas tank on my 95 mustang. You are going to have to drop the tank. There is a rubber seal where the filler neck goes into the gas tank that has failed and must be replaced. You are losing even more gas than you think. Everytime you make a left turn gas is sloshing out through that bad seal.

2007 GMC Envoy - Gas gauge showing empty and check engine light


This is a safety feature that the vehicle brings. You need to reset the E.C.U on dealership or it will keep doing it to you. It was probably caused by one single time that you did not closed the fuel cap correctly. Good luck

2004 GMC Yunkon Denali is misfiring


it could be alot of things...you could start by routine maintnence( new spark plugs, spark plug wires, air filter, oil change, the in line fuel filter) also take into consideration what kind of gas you are using...i know it sucks spending $100 a week in gas with your AWD 6.0 liter V-8...but if ur not running premium it could very well be your problem. I have also heard of the denali's having oxygen sensor issues...is it throwing a check engine code?
