Fuel filter/fuel pump problems

This is one that could be anything For starters clogged catilitic converter clogged fuel filter clogged or colapesed air cleaner low fuel pressuer from bad filter or faulty pump Bad throttle positioning sensor.You will need to check exhaust output fuel pressure and TPS voltage.You have to narrow it down Sorry not much help here but I need more info

Will it run if you jumper the pump relay ?

sounds like most of you have fuel pump problems disconnect the fuel line and check to see if any fuel comes through the line when turning it over, no fuel pump problem, or change fuel filter

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????20

It sounds like a fuel pump resister. I had exact same problem with my regal, resistor has 2 black leads, ceramic and it shapes like horse shoe. mine cost $79.95. Before I know this, I had the dealer replaced fuel pump, fuel filter still didn't fix the problem, and they suggested injector madulator. Very fortunate I ran into a friend has the same 1999 buick regal V6 SC and had same problem told me about this fix. I called 4 buick dealership parts dept.and asked to buy a fuel pump resistor they all told me that there no such thing! So, if want this p[art go to GM parts dealership.
And ask them to show you where it locates. Because it hidden inside engine compartment.

Hope it'll fix your problem like it did mine.

remove and have the injectors cleaned and set
leaking injectors will allow fuel in when not required causing the detonation

I had this problem as well. The tracker had sat for 8 years and would only run off of starter fluid. I replaced the filter and fuel pump then I had no fire. Located under driver side dash in the fuse panel theres a fuse for coil. I don't remember which one, but, I am pretty sure it is a 10 amp fuse. Or just do like I did and replace any bad fuses. If that doesn't work it will be a relay located above that same fuse box.

change fuel filter,if that dont fix it run power to the fuel pump and see if the pump is turning on hope this helps

The data svcs only show 1 fuel pump relay on this vehicle, it is located under left side dash under and perpindicular to ecm.

Fuel pump in back in the gas tank.
