2002 Focus fuel pump

2002 Ford Focus SE wagon
2.0L Zetec engine
83,000 miles
Bought car a year ago when it had 68,000 miles
About a week and a half ago engine would not start. Donít know if this is related but had the car filled up with gas the day before.
Sprayed starting fluid into the air cleaner outlet tube and engine started right away.
After this I replaced the fuel filter and put Seafoam in the gas tank to clean injectors. Drove the car about 120 miles
Saturday I again filled the gas tank (different station) and parked the car. The car sat in a heated garage for about five hours. When I went to start the engine, it ran for awhile but was running rough and stopped running after 1 minute. Then the only way to start it was with starting fluid but it would stop after it used the fluid.
Checked the fuel pump fuse and it was blown. Replaced it and the engine started.
Since the engine would not start a week and a half ago and the blown fuse now, I was thinking the fuel pump could have a bad spot on the motor. Does anybody know what the impedance/ohms of the fuel pump would normally be? Can this be checked from the module?

Thanks,
Scott

Could be that the fuel pump screen inside tank is stopped up too to overload pump, you're at about the right mileage for it if they use ethanol in your fuel. Both my '00 and '02 did it at past 75K miles, pulling pump and cleaning screen cured it. These cars have lots of trouble on early models with that.

2002 focus fuel pump

Thanks for the help. That would make sense then with adding fuel to the tank and stirring up debris. Would anyone happen to know the correct amp draw from the fuel pump when operating? Does anyone know what change was done to the later models that corrected this issue...or is it still an issue?

Pump module design was changed. Thinking the fuel suppliers did their part there somewhat too to make the fuel cleaner. Early ethanol had all sorts of problems. While the fuel is not perfect, much better now.

There really is no amperage number since the module driver varies the voltage based on demand.

If the screen clogged you gotta yank tank, or eventually burn the pump up, it is fuel cooled. Lower throughput overheats it. the more you delay the more chance you'll end up doing it twice, once for filter screen cleaning and second time for pump that died because the job was postponed. I did mine early and many years later still running same pumps.

Thanks for the testimony concerning your own fuel pump longevity. Actually the reason I asked about the ohms and current draw was to back up the reasoning of pulling the tank. I figured if I pull the tank and the screen is not clogged I would replace the fuel pump. I just would like to have the knowledge that I am doing the correct thing and not just replacing parts to replace parts. Dropping the tank was already on my bucket list.

Thanks for the advice,
Scott
