2000 olds siluette fuel pump not functioning,replaced fuel pump,tested relays,still dont hear it pumping. suggestions????

Do you have a multi-meter or test light?
There is a fuel pump fuse, in the fuse/relay distribution box, did you check that? That fuse and the fuel pump relay would have a "hot at all times" designation. Use the test light to see if the fuse has power at it. Next move to the FPR, pull it out and check for power. One of the relay terminals (it is #30 designation on the relay) would also be hot at all times (this terminal is coming directly from the fuse). Use the test light to check for that.
Look at the relay: on the side is a descriptor, or a diagram showing the relay terminals usage: #30 is the power feed, #87 is the feed on to the gas tank to the fuel pump. The other two terminals are the "coil side" of relay, #85 and #86, the coil side is what turns the relay on (from a signal from the pcm) and lets power pass to the pump.
If you have power at the relay terminal, you can take a short jumper wire and jump terminal 30 with 87. this will check the wiring circuit- it will send power on to the pump, and it should start working. If pump does not work, check for power on the gray wire at the gas tank connector. If no power, (and you still have the relay jumpered) then you have a bad wire from relay to the gas tank. If there is power on the gray pump wire, but still no pump when it is connected, then possibly the ground on your car for the pump is bad, or you maybe got a defective pump. Not likely, but it has happened before.
Now if you can jumper the relay and turn the pump on, we are down to the problem: apparently the coil side of your relay is not working-not turning the relay on, because of a missing signal from the pcm, or because the ground for the coil side is bad, or maybe just a bad relay.

I have a 2005 dodge neon that will crank but wont start. I have replaced the cam shaft sensor, crank sensor and the coil pack. Iam also not getting spark to the coil pack. Any suggestions?

Primary voltage to several systems, including the ignition coil, dark green wire with orange tracer. That voltage comes from asd relay. There is a fuse for asd relay. To check for voltage the engine has to cranking. The control side of asd relay, the computer has to ground it before it will energize. Did you check wiring circuits for cam and crank sensor connectors before replacing sensors? Are there any applicable trouble codes?
Are you ok with testing wiring circuits?

No fuel getting to motor so no start. replaced pump fuses and relays all good. there is spark

you will need to check the plug to the pump on top of the tank. check for voltage. then if no volts trace the wires back. also you should check the relay have some one at the relay listening to see if it clicks when you turn the key. no click no volts no volts may be a warn out relay, if it buzzes change it.

No power to fuel pump on 92 olds silhoutte

The oil pressure sensor only keeps the pump running after the vehicle is started. If you turn key to on, the computer should signal to the fuel pump relay, turning the pump on for a couple of seconds to pressurize the fuel system. Then the computer signal stops. When the key is turned to start-cranking the engine- the computer again energizes the fuel pump relay, keeping the pump running until the engine starts.
If you have a voltmeter or test light, pull the relay out and check the relay terminals. One should be hot at all times-the power feed for the pump. The computer signal will be on the coil side of the relay-will have power for 2 or 3 seconds after key is turned to on. Or it will have a constant signal when the engine is cranking. If you can find both hot terminals at the relay, then start looking for a bad wire from relay to pump, or a bad ground for the pump, or a bad ground for the relay's coil side. Post back if unclear or other questions. When you pull the relay out, the diagram for it will be on the side of the relay-telling you which is the power feed and the terminal to the pump, and the coil side of relay, both the coil power side and the coil ground terminal.

Air ride suspension control diagram

Best bet for a wiring and parts location diagram is There is a switch attached to the chassis (with a rod connecting it to a rear control arm), on or near the air pump at the rear of the truck.The switch could be faulty, or the rod may be disengaged or damaged. The pump is rather expensive - I would remove it for cleaning (in particular the air filter) and testing first.

I have a 97 chev suburban 350 and no power to the fuel pump ,new fuel pump,fuel pump relay fuse is new,checked all wiring no cracks or breaks all along from fuse s to pump all good,just when i turn key is...

I would interrogate the fuel pump relay socket with a voltmeter or test light. There should be one hot terminal from the ecm b fuse. There should be a terminal that has chassis ground for the relay coil. The positive terminal for the relay coil comes from the ecm when the key is on. If you have trouble interpreting the results of these troubleshooting steps, feel free to comment back. The circuit is on the right of the diagram about 1/3 down the page.

2002ford windstar will not run with fuel pump relay in but will run with jumper wire in its place

So the jumper only takes the place of the higher current
contacts when relay is energized

Now use a wiring diagram to diagnose the relay coil or
control circuit to relay coil,basically found your problem

I have a 1996 yukon 4 door it wont start thought it was the pump becuase i didn't here it dropped the tank and checked it by running wires to it and it works checked the wires and there is no power spayed...

You did that the hard way
If you had a wiring diagram,you could have started anywhere in the fuel system,checking as you went,until you had no voltage drop.
You could also have found a place, to put power to the pump, without removing the tank
There is a fuse,relay in most cases,fuel pressure regulator,etc in all vehicles. Have to know where and what to test.
Your working blind with no print of a system, your not knowlegable of.

Fuel pump will not come on. I have power at the relay but no control power to turn the relay on. I jumpered the contacts and the fuel pump fires right up.

If you powered the fuel pump by bypass the relay, then either the relay is faulty or the wiring to the relay is faulty or there maybe a fuse that is blown.
When the fuel pump relay coil is energizes, the relay contacts will close to supply power to the fuel pump.
Remove the relay then identify the relay coil connectors, then apply 12volts to these connectors, if the relay clicks then the relay is probably OK unless the relay contacts are faulty and then the fault is in the wiring to the relay coil.
Get a service manual wiring diagram and trace the wiring from the relay connector back to the control box/ignition.
You can use a 12v globe or a multi-meter to check the relay coil at the relay connector to see if it energizes
