If you're just going to cut and paste the same question over and over, without doing any troubleshooting, you'll never get to work in your truck.
I gave you some places to start looking for problems.
Its a very simple system. Gas tank, fuel filter, fuel line, fuel pump, carb.
There is no magic internet answer. You'll have to put in a little effort, to figure it out.

When you changed the fuel pump, did you happen to notice if the pushrod that runs on the cam fell out? Its a pretty small rod and might have dropped out in the midst of your repair.
I'm not trying to be a smart a**. It just seems as if you aren't following through on your troubleshooting. Really, these Suzukis are some of the simplest vehicles ever made. No complicated electronics, simple fuel systems, simple drivetrain, easy to work on.
Keep looking, you'll find the problem.

thanks I haven't even thought of that. I was told to take valve cover off (since I need toi change gasket anyway) to see if the rod was in there or hooked to pump rod, is that correct? Also someone said that either my fuel pump relay was blown or my charchol canister was clogged. Does that make sense to you? Sorry for the questions and thanks!

I did that buddy
And? What were the results?

As for experience: That's what you get, when you don't get what you want. You try something, it doesn't work, you try something else. The failures are experience.
I've had more than my share of failures, that I learned from.

Its hard to see the fuel pump rod. Its semi hidden in the head casting, back where the cam exits the head for the distributor drive and rides on the cam lobe. Easiest way to check is pull the fuel pump and feel with your finger. Also, if the pump rod is in there, it will try and push the pump off the head, when you loosen the bolts.

Another EXTREMELY unlikely event is a flattened pump lobe on the cam. But lets not go there right now.

There is no relay, with a mechanical pump. Plugged canister will only show up after the fuel cap is tight and the engine has been running awhile. Loosen the cap, and the problem goes away.

The stock Hitachi carb is loaded with electrical crap. Fuel enrichment control, high rpm deceleration idle fuel circuit cut off, idle up vacuum controls, etc.. That plug is for some of those systems.

If its gone, post here and I'll get you the part number. Easiest reliable source, is direct from Suzuki. You would be amazed, at how many parts Suzuki still stocks for the little Samurai.

Sun visors, door panels, glove box, ash tray, decals, fuel pumps (cheaper than aftermarket), valve springs, etc. . . . . .

Almost all, well, all the fuel system controls can be eliminated, with an aftermarket carb. Problem is, you can't pass emissions testing, when you change the carb.
With a Weber, or, similar aftermarket carb, these things will run with just power to the distributor and coil, provided you are parked on a hill, to get it push started. As I said before, they're SIMPLE.

A Couple of Things . . .

I forgot to ask if you have spark? I know you're chasing a fuel supply problem, but you could have a broken timing belt, which in turn would mean no fuel pump actuation by the cam.
Take off the distributor cap and crank it over, make sure its moving, to make sure the cam is still connected to the crank.

Hey thank you for everything. I wanted you to ask you before I took off the valve cover and check the rod placement, you said maybe timing broke. I sprayed starter fluid in it and cranked for a minute, does that still mean the timing belt could be broke? also,the summary is this. new pump, distributer cap and rotor, new plugs, wires, new filter at gas tank and between carb and pump. Still no gas going in carb. That's the update but let me know about the above first sentence please. and thank you so very much!

Did it fire and run at all with starting spray?

The engine will crank fine with a broken timing belt, just wont start. You'll also notice a strange rhythm while cranking. It wont seem normal, as the valves aren't opening and closing. A quick check for a broken timing belt is pop off the distributor cap, note position of rotor, crank engine, check to see if rotor has moved.

Okay buddy good morning. I did all you said. Last resort was the pushrod, I took fuel pump back off, I found the push rod, is it supposed to be real loose? I slide it out and put it back in and noticed to end of fuel pump was against it. Isnt it supposed to engage into that attachment and push inward? I still have no gas after all I have done. Do you have any other ideas?? Your advice and anyone else's is appreciated

If you've got a working fuel pump, it has to be a fuel line problem. 99% sure. Either its plugged, or, its got an air leak in it. Are you sure you were able to run air back through the SUPPLY line to the tank and hear it bubbling in the fuel? There are supposed to be two lines from the tank, connected to the pump. One is the fuel feed, the other is the return. you didn't get them switched, did you?:confused:

Update?

So. . . . what was the problem? Did you get it fixed? Did you give up? Sell it for parts? Would you like to tell others about what you found?

It could help someone else, that has the same problems.

When I changed my fuel pump I had to prime the replacement. If you have any holes in the fuel lines you won't get fuel through, the usual problem area is where the line goes into the top of the fuel tank.
