    There is four of them. Which one is it?

    A relay will normally be located in the area of the fuse box either under the dash or in a power distribution box under the hood in the engine compartment near the battery.

Its in the engine compartment of the vehicle on the passenger side of the vehicle by the charcoal canister (behind the passenger side headlight, behind the core support, in a bank of relays.)

2001 Mercury Sable Intermittent Fuel Pump?

You are right that it could be either component, or something else electrical. The security system will kill the fuel system if the wrong key is used or the system is acting up.
A mechanic would check base fuel pressure with a gauge and also see if the pump is getting power from the relay when it fails to start.

My 97 monte carlo will turn over but there isn't any power to fuel pump I know it works and I've changed all the fuses and relays and also got the key checked.... I don't get it also checked...

The ECM BAT fuse powers the fuel pump through the relay. If the gray wire has power and the black wire has ground, and the fuel pump does not operate, its bad.

My 1996 Dodge grand caravan is not starting up but will turn over. I have installed a new crankshaft sensor, new fuel pump and still nothing. Coil pack is good. No spark from harness connecting to the coil...

Hello fellow auto mechanic. Let's take one step at a time .Your engine turns over because your starter is connected directly to your battery.It's possible that the crankshaft sensor was the the problem, but NO. Also new fuel pump well maybe but not yet. There may be more to this story and as always not what you may have done but what you don't know you have done.
First when you put your key into your ignition and turn to on you should here a noise at the back of your cars fuel tank. The sound will be a whiiiirrrrr sound indicating that your fuel pump is doing it's job and pushing fuel to the engine. It will be a very significant sound and you will know it when you here it. If this doesn't happen go to your power control center under your hood on LEFT side open it and you will find a relay for your fuel pump. This is an easy check because you can pull the relay for your horn LABELED the same, and use in place of your fuel pump relay to see if you can start your car. If this doesn't do it ,one more test look at the relays and find the ASD relay this is the main shut off to your vehicle. Now if this doesn't work it is very possible that you or whoever replaced your fuel pump may have crimped some wires or even forgot to hook up the the plug to the pump. This kind of stuff happens all the time, that's why people are always asking questions.Check the simple stuff first, and I believe you will find your problem. It's probably something very simple , don't get discouraged.
One more thing , why are there so many 96 Caravan problems? Please get back to me on the above and let me know if I have helped you. Don't forget to vote and GOOD LUCK.

How do you know if the fuel pump or just the strainer is bad? i've had to "prime" the fuel pump (turn key forward) for sveral months now in order for the car to start if i dont, then im stuck...

I personally don't think its either. Do this for a living. You have an electric fuel pump and in most cases if they go bad it just plain doesn't work. If it was the strainer you would have problems with fuel pressure while running at all times. As far as having to "prime" the system you could be looking at a loss of pressure somewhere but sounds to me more like a relay or an electrical problem. What I am saying is that as you turn the key to "prime" it, you are maybe not priming it and its more of a hit or miss on the electrical problem. I would check to make sure your fuel pump relay is working. It should engage for about 5 seconds after you turn the key. You can feel if it is engaging by touching it when someone turns the key. Also there may be an ECM relay thats not engaging at all times. Are you able to hear the pump turn on when you turn the key? If yes when it will not start is there power (electrical pulse) on the injectors when it won't start? I would just hate for you to drop the gas tank for no reason and pay for a pump for no reason. Pumps are bad or not bad. Work or doesn't work in 99 percent of the cases. Fuel pressure doesn't change that much either. If there is a blockage it's there or not. Just my opinion and I hope it helps. Good luck.

The fuel pump on my 1995 Firebird Formula quit running. I've even tried feeding 12v directly to the grey wire on the fuel pump relay and it still doesn't run. Can a generic fuel pump be installed...

No, the fuel pump in the tank needs to be replaced. It's not too bad to remove the tank, hopefully you don't have much gas in there though.

Good Luck!

It cranks but wont start. Checked for spark with the lead plug wire from the coil to the distributor cap. No spark. I changed the coil still no spark. I've been told its my fuel pump. But I've...

if you are sure there is no spark and you have replaced the coil,then the only other thing it could be is your spark control works off your computer to tell your plugs when to fire..somettimes they go out only when they heat up and will start working again after they cool down,,but sometime they don"t give you any warning and just stop working all together.. would say you have a bad Spark Control is pretty easy to fix, just make sure you use or buy the right tools to take it off , ask at the Auto parts store to get the right tool, and the right part..

Your crank position sensor is on the left side of the bellhousing at about 11 o'clock looking from the rear.
Harness plug is on the drivers side near the master cylinder. Using an ohmeter (digital) you should see no continuity between the b&c terminals (as marked on the connector). If you cannot hear the fuel pump running when you turn the key on, I'd check power at the pump harness connector as well. Less frequently the cam sensor inside the distributor can give you similar problems...check that too. I have no idea what a fuel pump sensor is so I'm guessing you checked or replaced the relay. You should also check the ASD relay as that controls starting as well.
Before spending more $ on parts you don't need, get yourself a haynes or chilton manual and do some testing.
