yes you have to drop the tank. you will also need a fuel line tool to unhook the fuel lines. before you drop the tank see if tou can reach and wiggle the electrical connection on the top of the tank. these pumps have a pigtail issue. please rate

Sure there is!
DO THIS FIRST!!!
When you turn the key on, and the gauges and warning lights come to life, does the needle on the fuel gauge move a tiny bit? It should. If it does move a hair, this is a good sign your gauge is still good. If not, keep reading.
The gauges themselves are usually not at fault, but they can fail, of course. Usually, it's the sender or float that's the culprit. The assembly resides in the fuel tank in the module or unit that houses your fuel pump. Many customers (when faced with the cost of this tank job) will opt for waiting until the fuel pump goes bad, and replacing pump and sending unit together. However, there are obvious drawbacks to this!
ONE test you could do if you are good at driveway car work is this: Crawl under vehicle and find the bundle of wires (not tubes or lines) that goes up to the top of the fuel tank. Sometimes you can reach it through the rear wheel well. Follow this small group of wires up to wherever it plugs in to the pigtail coming out of the tank. THis could be on top of tank, or just outside the perimeter of the tank. Unplug this connection. Using a common 12 volt test lamp probe, ground the test lamp, turn the key to the "ON" position so dash lights up, and touch tester to each wire tip on the end not connected to the tank (engine side of wire harness.) Have someone watch the fuel gauge as you touch the leads one by one. The gauge should move when one of these is grounded thru the lite. Total deflection of the needle means your sender is at fault, not the gauge. BUt it's usually the sender, anyway. THey're cheap enough, but the labor on a tank job can vary from place to place.
Good luck, TT

Look in the fuse box under the hood. Find fuse "ECM B" which is on circuit 120 which excites the fuel pump relay. This is the fuse you want to inspect. The relay pin next to it is controlled by the PCM. The other 2 pins on the relay control the pump and the other the prime circuit.

sorry to say, this is typical of the echo, after a couple yrs, the fill tube begins collapsing, not allowing enuff fuel flow,, your alternatives are to replacew the fill tubes, or to just pump fuel very slowly.

The reason the gas station pump shuts off is when the fuel reaches the tip of the gas nozzle, so when you are filling your car and the gas nozzle (gas stations pipe) keeps shutting off it means that the pipe that runs to the gas tank is not open completely, what happens is when you pump the gas in the car the supply pipe from the gas tank opening to the tank fills up quickly and this causes the gas station pipe nozzle to shut off, have some body take down the gas tank and have a look at the gas tank opening and also gas supply pipe that runs from the gas filler opening ( on the car body) to the gas tank. Have a look at it and please don't forget to rate the answer if it was helpful, thanks!
