Default Fuel Pump Testing Problem

I need some help with what I think is a fuel pump problem. I just picked up this '99 5.9l Ram that sat for a year. It started ok and I got it home (1/2 mile) but no start now. Spark is good there. I'm not YET familiar with this truck and I'm trying to figure out how to jump power to the fuel pump (I did bang on the tank). No noise from the pump with the key on and I am getting power to the 'Fuel System Relay' in the fusebox under the hood. All other fuses checked fine.

I cannot find the wire leads to the fuel pump w/o sliding the bed or dropping the tank which I want to avoid until I clean up the rusting bolts later. I've sorted out a few other problems but need to get this one running for work.

Any ideas on how to 'hotwire' the pump to test it??? I do not have access to a fuel pressure tester right now.

Well I was about to say grab a fuel pressure tester, but you saved that comment for last. Go to autozone or harbor freight and grab one!

I wouldn't mess with the wiring, just drop the tank or remove the bed, besides if the pump turns out to be bad then you are already more than half way done in replacing the pump, haha.

Gotcha Dude and thanks. I'll get the Haynes as soon as I can but I had to get things like tune up, fluids, hoses, belts and the like first which drained what little there is to spend these daze.. Some POs can PO me with just the slack minimum maintenance if you know what I mean. Also, a fp tester which is one of the few things I do not have in the tool bin.

I still would like to get an electrical jump spot to test in the future w/o having to break the truck apart. I've done this alot in the past as a starting point just to be certain.

I need to get this going so I can use it for work and sell my old car.

You can jump power at the pump relay but that won't rule out a wiring problem. Power and ground need to be checked at the pump connector in order to do that.

Yea I understand what you're saying. Well I don't know where to tell you to start, personally I would try and get that fuel pump tester, rule that out, then go ahead and check things like the wiring.

You can't rule out the pump if the wiring to it is defective. Sure you can try rigging up a battery and some jumper wires to test the pump, but I've seen a guy set himself on fire trying that stunt. Gaining access to the pump connector and checking for B+ with the relay jumpered via volt meter and then checking continuity to ground is an easier and safer way to go.

I would never recommend anything to anyone that is obviously dangerous, certainly you cannot rule out faulty wiring with a fuel pump tester, but you can atleast get a place of where to start, you're a technician and know that when fuel pumps fail, many times they do show some amount of pressure and even if they doesn't you still can say well it is either the pump is bad or the wiring is faulty. Next step, take a volt meter and wire it across the pump motor terminals and then put the key in the ignition and turn the key to the on position and see if there is a voltage drop, if there is than the wiring if fine and the pump is faulty. The motor usually doesn't die, the pump assembly just wears out, but you know this.
