I wonder if my suburban 91 has any fuel filter before the fuel pump (between the fuel tank and pump) that would be changed sometimes in a while.

According to advance website your fuel pump is electric and inside the tank. the only pre-filter is thus the screen around the pump inlet. years of detritus can collect around them, but you are going to have to lower the tank and pull it out to see. it is 20 years old and a replacement would be in order anyhow if it has never been changed before.

Hi, I believe you hit the nail on the head. Black stuff in the filter Meaning that there is something in the tank. You have to drop the tank and clean it out. Good luck.

My suburban quit running while driving down the road. Seems like not getting fuel. Changed fuel filter. Still no go. How can I determine if it is a pump.


Ah, the famous Chevy fuel pump death in the fuel tank. This is a HAZARDOUS job. Unless you are a sharp mechanic (I assume you're not or you wouldn't be asking about the fuel pump test) I'd take it to the dealer. Sorry.

Usually that is a bad fuel pump. Filter is not on the tank. Test it when it doesn't start, or listen, as when you first turn the key to "run", you should hear the fuel pump cycle.

The fuel pump module may not be bad. If you hear whirr that is good. Did you change both of the filters, the one on the fuel pump and the external filter (the one along the frame of the trunk). Also did you clean out the tank? If you did all that the next step would most likly point to fuel injectors.
