What IS your fuel pressure?

"both front and rear fuel pumps"

I assume this is a dual tank truck? I have never had to work on a dual tank system but, my first question would be is the fuel being pumped from tank to tank due to a bad check valve, or something? Do both pumps run at the same time, at any point in the tank switching processs? What kind of stream would you have, running both pumps at the same time?

i am only using the front tank and have the rear tank as a storage tank only / using an aux pump on the rear tank to get fuel into the front tank the front pump is only 30 psi/if there was a bad ground would it cause the new pump not to pump correctly or would it not pump at all

30 psi, as you know, is along way from the spec of 50-60 psi. The question is whether the pump is not producing the proper pressure? Or, is pressure being lost?
I'm not sure of the "plumbing" between the two tanks but, make sure pressure is not bleeding off to the auxiliary tank. Make sure the fuel has no place to go except the fuel-rail. If pressure is not being bled off to the auxiliary tank, and you have no leaks, and you have verified GOOD power and ground,...you have to question the fuel pump. NEW stands for Never Ever Worked.

all of the factory plumbing to the rear tank has been cut and blocked off i put 1 hole in the bottom of the rear tank and 1 hole in top of front tank with an aux pump and filter on a separate fused circuit all by itsself.. the factory plumbing to the front tank is original.main line to the fuel rail then return line to the tank with the egr vent in top of the tank im going to try attatching another ground off the wire to the pump to the frame of the truck tomorrow and see if that helps or not but thanks for your suggestions //

Roll #1 up to TDC on the compression stroke. Drop the distributor in with the rotor pointing directly to where #1 would be if the cap was on. As the distributor shaft lowers into the engine, it will turn slightly as the teeth of the gears "mesh up". Take that into consideration when beginning the descent.

If you are sure you are on compression stroke (remove #1 spark plug and plug the hole with a finger. Roll the engine by hand until pressure forces your finger out), and at TDC (visually, if you can, watch the cylinder come up and VERY momentarily pause be for going back down. (That pause is TDC.)), then, configure your plug wires on the distributor cap to match the firing order in the Diagram. Make sure #1 cylinder is where your rotor is pointing. (in your picture, it looks like the rotor is pointing to #5 on the diagram)

Does yours look like this?

A google search brought me to this thread on another forum.

Copy and pasted:

Just check timing on a 93 Ford F 150 4.9L V6. Now theres two places to check the timing one from driver side and one from passenger side, both sides have timing marks. Which side is the correct side to check the timing? I went with the ones on the passenger side.

The passenger side is correct. Pull the SPOUT and check that it's 10° BTDC. That engine family has been around since the mid-to-late sixties, and the driver's side pointer is obsolete and unused since the mid-seventies.

That doesn't look too bad. If the #1 cylinder is STILL at TDC of the COMPRESSION stroke, then put the cap on, put plug wire #1 were the rotor is pointing, put the rest of the plug wires on, accordingly. If all is well, it should fire up. If it doesn't, turn the distributor, slightly, one way or the other and try again. It might take a little tweaking of the distributor position to get it to fire up. When it fires up tweak the distributor to get the best idle for warm up.
