Hi fellas... I have and old Mazda B2000 work truck that's just used for hauling off trash in... It's a 1983, standard transmission; 6cyl carburated. My problem is I'm not getting fire back to my fuel pump.. I can turn the ignition switch on and at timesthe dash lights with work and sometimes not... When they do I get fire back to the fuel pump. The engine will always turn over even if the dash lights fail to connect..I did try to enstall a starter switch to see if that was my problem. I enstall it to the back of the key ignition and plugged it in but that failed to be the problem...Since it's and old work truck and I really don't have the knowledge or paitience to figure these electrical problems out can I just rig up something that will get me juice going back to the fuel pump..Like I said the engine turns over when you turn the ignition switch and I really don't need all of the electrical stuff working.. Just the starter and fuel pump..No, I'm not a very bright mechanic but if someone will walk me thru a solution I'd really appreciate it...Thanks... ...Pete

6 cylinder?
With the ignition on or in the start position you should have 12 volts to the fuel pump. Have you checked for voltage at the pump?

You said it was carburated. Why would it have an electric fuel pump?

I don't know how many owners it's had before it fell into our hands..But the fuel pump sits on the frame next to the fuel tank.. It has a two wire electrical connection coming from the top of the fuel tank that plugs into the fuel tank pig tail.. One small wire is "black" and the other is "black&white"...Does that help any... Thanks...Pete

It needs to be powered through the ignition switch. You don't want the pump to run with the key off.

It goes through a 15amp fuse after leaving the ignition switch.

Well I call myself checking connections...fuses and everything else I could think of... Would the "black and white" wire that goes to the fuel pump be a different color coming off of the ignition switch? And the 15 amp fuse your referring to?... Is it under the dash also( haven't seen any fuse under there) or located somewhere else...And thanks again for helping me...Pete

Yes, it's going to be a different color because it is not the only accessory being run off that feed. You really should have been testing all of your fuses with a test light before even posting here. That's basic stuff.

Pete - even 1983 I think most of these had substandard battery cable ends right at battery. If the prime source of all electric power is marginal so will everything else it's doing. Check that. Neg off first, on last and everything at battery needs to end up clean and tight - wire brush, sandpaper or a quality new splice end up to whole new cable if a horror show there,

Hi fella's...I found and appropriate "hot" wire coming off of the ignition switch... It is a "black and white" wire. I tied into it and run it under the foor board and tied it into the pigtail on the fuel pump. I also run a ground wire from the other terminal on the pig tail and grounded it to the frame...So far everything seems to be working fine... I can hear the fuel pump working when I turn the ignition on and its been starting everytime.. As long as I can drive it one one end of the yard to the other and drop off limbs at the burning pile I'll be staisitied with it... lol... Thanks everyone for your help...Pete

That will work good right up to the point where the truck catches fire.
That's not the way to fix this problem.
