With the key off, pull out the relay and use a test light or voltmeter to find the hot terminal in the relay socket. Then use an ohmmeter to find the terminal that goes to the pump. The pump terminal will show a few ohms to ground, whereas the other two terminals will either show zero ohms to ground or will show infinite ohms to ground. Use a short jumper wire between the hot wire and the pump wire.

well first the fuel pump relay is bad, that is easily replaced. next you have no spark. the first thing you do is take the cap off the distributerand crank the engine. if it spins that tell syou thyat at least the tang or gear on the shaft of the distributor is ok and not broken. next thing is remove the #1 plug and use a 1/4 drive extension 6" long and turn the crank by hand until the #1 cylinder is top dead center(put the extension in the hole of head where the plug was and you should feel the top of the piston also make sure you can feel the top of the piston with half the extension this way you don't drop it in the cylinder with the piston at TDC(top dead center) the rotor of the distributor should be pointed at the #1 firing position. IF it does not that means your timing is off and you need to retime it by taking off timing cover and either replacing the belt/chain or gears. now if you do not have a distributor and you have a coil pack there could be only 2 things that won't give spark. either a bad coil or your altenater is bad(the battery is responsible for starting not running the vehicle like alot of people assume. the altenator energizes the coil which inturngives spark. hope this helps you please rate this thanks

the relay and fuse are in the power distribution box under the hood. as far a by pass you still can use an aftermarket electric pump ,however the cost will be about the same as re3moving the old pump in the tank if that is the cause in the first place. if all you need is the relay replaced then i'm sure that the pump is still good. if the pump is bad then make sure if you by pass the in tank pump that the new under hood electric pump has enough pressure to give the needed gpm(gallons per minute) required for your system and that if wired into the current fuel circuit that you dissconnect the wire harness to your tank pump

it doesn't have a fuel pump relay it has a fuel pump control unit and it is located on the chassis back quarter drivers side near the tube cross member for chassis on top of chassis rail near bed mount. locate the rear springs front perch and it will be above that on top of rail.
hope this helps. good luck and please ask any question you have.
