1990 Caprice Brougham turns over but not getting gas, Replaced fuel pump and checked line also, No gas was getting in the fuel filter after I replaced fuel pump.

No power to the fuel pump is likely.

Fuel pump can also cause this problem, You find out if fuel pump is faulty by energising directly fuel pump, and checking fuel pressure.

Check also the fuel line, starting from gas tank, often oxide and dirt from tank can obstruct the hose. Disconnect fuel hose and blow air into it .

Check also air filter and air intake.

when you first try getting fuel going. you may have to turn the key on and off a few times to build up pressure. if you can hear the pump working it will change when it builds up pressure. if its not then I would say you have a line leaking. check all your connections before you have a fire

inspect tank unit and harness for burnt connections

Have you checked fuel pressure (put a gauge in-line with the fuel line - to measure fuel pump pressure).
It sound like you have a bad fuel pump.

i would think if it were the relay you wouldn't hear the pump come on. I would unhook the fuel line just past the fuel filter. turn the key on long enough to see if the pump is pumping and is it getting past the filter. if it is you can rule out a possible clogged filter and you know the pump is pumping. I would then start looking for a clog. or locate the relay take it to the part store and get a new one. the problem is the relay only relays electrical signal to the pump that turns it on and off etc it doesn't tell it to pump or not pump gas so if you can hear it running it's not the relay

Engines need fuel, air spark compression and correct timing to run.
I would start by checking the fuel pump and fuel pressure

check for blockage at your fuel filter first. Since thaty is the easiest to check if your getting fuel to come out the filter, move on to your injector. There is a good chance that when you ran your car out of gas nit sucked some sediment into your line and blocking the line somewhere. Let this be a lesson to everybody, never run your car completely out of gas. VERY BAD!

wrong vacuum line hooked to fuel regulator

If you change the fuel filter and still not getting fuel to the engine, then the other possible problems are:
- Clogged fuel lines due to 'dirty' fuel.
- Defective Fuel Pump which may not provide enough pressure to 'push' the fuel pass your new filter.

Hope it helps.
