Mercury sable 1996 changed fuel filter had brown gas in it did this ruin fuel pump. Can hear pump when trying to start car


Most likely the fuel pump is ok, but there is likely air in the fuel line that you need to bleed off under the hood.

It is possible that the fuel pump went bad, and the way to know is to check the fuel pressure (same place you bleed it under the hood). The fuel pump is in the tank, so it's a real pain to change.

Yes you can just change the fuel pump, there are genuine and aftermarket options available, You need to remove the original pump from the cradle and this will allow you to confirm the size of the replacement pump.

HOW MUCH WOULD IT COST TO HAVE A FUEL PUMP INSTALED


George,
No simple diagram for changing the fuel pump. It is located inside the gas tank. The gas tank needs to be removed to change the pump. The pump is part of an assembly which consists of the pump, fuel gauge sender and pick up. You also need to change the fuel filter when you change the pump. It should take a professional mechanic about 3 hours to drain the fuel out of the tank, remove the tank, change the pump and fuel filter. Multiple the mechanic's time by whatever the repair shop charges per hour for labor. There are several different pump assemblies for the vehicle. Price depends on whether it's 2 or 4 doors and 2 or 4 wheel drive. Best guess is about $600 total.

2001 grand am fuel pump runs but I only get fuel sometimes. Fuel pump going bad? Or losing prime somehwere? May have run fuel lines dry


Install a fuel pressure gauge on the rail and turn the ignition key from OFF to ON, so you can hear the fuel pump run. Do this about three times, then check your pressure. Check for drain-back.

You could have a clogged fuel-filter, but if it has been clogged for some time, its possible that it strained the fuel pump and could have damaged the fuel pump as well. If you have low pressure, I would suggest changing the fuel filter first to see if it improves. You may find that you need to change both. If the fuel pressure drops rapidly after turning the key off, you have an issue with the check valve in the fuel pump, and the assembly will need to be changed.

A 460 engine that acts like its not getting enough fuel. Will start but runs as if only on half the cylinders missing badly or such.


Check your running fuel pump pressure. If (as I suspect) it's too low, first try changing your fuel filter. After changing the filter, recheck the running fuel pump pressure. If still low, check you fuel pump pressure regulator. If OK, you may need a new fuel pump.

Also probably would be a good idea to replace you air filter.

Good luck!

2000 dodge ram diesel 2500 . What is a fuel injection pump mechnical failure? a fuel valve feedback circuit?


This usually happens when the lift pump gets worn and fuel pressure drops below 7lbs and the injection pump has to work harder by pulling in the fuel and will destroy the pump,your is probably a vp44 fuel injection pump it needs replaced and they are expensive 1200.00+ but also change the lift pump or change to a fass fuel system,if the lift pump went out and you replace the injection pump it will ruin it in a short time.
The injection pump is not an easy job to change or for a novice mechanic as it has to be set in time with the engine at top dead center,and then the whole fuel system needs to be bleed of air.

Fuel issues?


since changing the pump makes a difference even for a short time, I believe you are on the right track with that. What you need to do is determine why after changing the pump the problem re-appears. What you need to do is check the fuel pressure at the throttle body, comparing "new" pressure to pressure from a non-working pump. You also need to check voltage at the pump to see if it changes. It may help to put an additional ground wire spliced into the existing one back at the pump harness...a poor ground will cause the pump to overheat and fail. I assume that when you changed the pump you completely drained the tank and cleaned it out so there is no issue there? Changing the pump will not change the operation of engine controls so I don't see a connection there. Pressure regulator may be an issue, but most fail to the "rich" side and you would know that right away...changing the pump would actually make that worse, not better. So, that leaves testing to find out the why of it.
