Can a battery cause your fuel pump to stop working after changing fuel filter?

96 chevy subr died tighten battery cables ran fine restarted the truck and put it gear died again someone said to change fuel filter did so, fuel pump ran for a few seconds truck still wouldnt crank now the pump stop working altogther|||No. When you first turn the key on the pump only runs for 2 seconds to pressurize the system then shuts off. It will only pump with the engine cranking and while its running.





I%26#039;m confused by your question though. What was the original problem? The engine didn%26#039;t crank over from loose battery cables?....or.....It keeps dying because you really do need a fuel pump but tightened the battery cables?|||seems that you have a short, try using a multimeter in serial to check pump amperage, so you would know if is good or not, try also drop voltage on your battery.|||You make it sound like the truck has a electric fuel pump, There is a high pressure cut off on electric fuel pump,to stop the pump if the engine does not start. Why did you have to be messing with the battery cables. It now could be any thing. why was the engine running while you were tighten the cables, you could have burn out a fuse or something. start over, and check all. You can leak down the fuel pressure at a fitting on the rail, but if you do not know what you are doing you could start a fire. Does the battery still have a charge? If it does then the fuel pump should be working When you say the truck will not crank do you mean the engine will not turn over or it will not run? If it does not turn over, then recheck the cable clamp and battery. if it will not run, i can not help with what you have giving me to work with.|||No it can not.


You change the filter. But was the pump workihg correctly before?A clogged filter can kill a fuel pump.If you blow through the inlet of a good one, it has no restiction at all.
