    See if it pumps out gas at the filter inlet line with jumping relay should I only let pump run couple seconds?

    Yes, just enough to see that it pumps several good squirts of fuel. Catch it in a jerry can or glass jar.

    From there we go back to the ASD relay for more electrical testing.

    You have to provide a ground from - battery to the - relay terminal, also. The - terminal of the relay is not grounded until the computer switches it actively to ground.

    So run a ground to the same terminal as the + on the fuel pump relay?

    Run 12v to the + terminal of the relay coil, and run a ground to the - terminal of the relay coil. This will close the relay and activate the pump.

    A relay has 4 connections: two for the relay coil inside, which actuates the relay by energizing the magnetic armature, so it has + and - terminals. And the load side, which is the switch that closes inside, has + and - terminals. The load side is the one that the pump connects to.

    Some of these relays have metal bodies and the metal case may be the ground for the - terminal of the relay. if it has a plastic case, there should be 4 terminals.

    It has 5 of the plastic body 4 prong relays Fuel Pump, Starter, ASD, AC, and Rad Fan

    You would want to jump B (Rd/Wt) and D (DG/Bk) as in this view here:

    Haynes is really fairly useless for this level of work. If you are into working on your own vehicles, it is much less frustrating if you have the complete factory service manual in your 'tool' inventory. It may seem expensive for one, but it can easily pay for itself the first time it is used and that is a good feeling. :)

    Any suggestions on a good brand of fuel pump to get or is there a good cheap universal pump that works? Last one I changed I just took what AAP had in stock and that was a Spectra and it didn't last long at all.

    Been looking at Rock Auto thinking about just getting the fuel pump module repair kit, but not sure if it would work with the Spectra because it says only for OEM pump

    Don't bother with a repair kit. Get Denso, Bosch, Carter or Walpro.

    +1! It's better to get the quality part so you don't have to do the job again sooner than expected.

    Get a Bosch 67608 fuel pump. Bosch is the actual OE part manufacturer for this particular application. I just replaced mine in my car. It is just as good of quality as the original and my particular pump was made in the USA.

    If you are having repeated fuel pump failures, it may be prudent to drop the tank and take a good look inside.
    You may find water, debris or muck on the bottom or inside the tank walls that is entering and killing pumps. After 21 years, the inside of a tank can collect a lot of garbage.
    You may be able to flush out and dry a non-rusted tank, but I have had to replace them before because of internal contamination as well.

    A friend of mine would never put more then five dollars worth of gas in at one time he often sputtered up to the pump. He had a lot of fuel pumps put in. His that first gen caravan.
