2002 cadillac deville stalls after half mile or so but not all the time

    This may not be the fuel pump or fuel line. I had the same problem in my 2002 deville and I changed the fuel filter. That wasn't it. For us, the car did two things. It would stall at idle on occasion. Or it would buck at about 35 mph. Did it about once per 800 miles. Turned out it was the crank sensor(s) A or B. They interface the engine fllywheel and the transmission. They are located in the oil pan. It costs $375 for a dealer to do it. I believe it is engine code 385, if you have it checked.

GM vehicles have their share of fuel pump problems; and this may be a pump going out. Have yours' checked out.

Replace the fuel filter. The new gasolines with ethanol tend to lloosen any crud in the gas tank, which then plugs the filter. When the engine stalls, the crud falls away, and it will run again until it plugs up again.

My 02 deville stalls

It may be tough to diagnose if you can't duplicate the complaint.
When it stalls you would need to know if you are loosing spark to the plugs or fuel to the injectors to proceed with any troubleshooting.
Could be anything from a faulty relay to the coil to the fuel pump.

Hi Aslanko, I would suggest taking the vehicle for a diagnostic scan. Even though no fault code has illuminated the engine check light, it has probably recorded one in the memory and maybe it will pin point the problem. Regards John

You need to replace your fuel level sensor. But previous post is right, if you're comfortable running based on fuel remaining and kilometers, don't sweat it. If you're keen, the fuel level sensor can be accessed from the trunk (under the liner on the passenger side, beneath the silver panel).
