I have no power to the fuel pump it,s new the relay is new and i see no breaks in the wires. someone said there mite be a roll over switch but i can,t find one. what else could be keeping it shut off? it will start on eather and run as long as i feed it manualy they don,t have the 3010 mule listed below, model kaf620e

SOURCE: no fuel

I come to find out,the fuel command is controlled by the computer, due to corrosion in the internals, it is not telling the fuel pump to turn on,so in turn, I run a switch to the power side of the fuell pump, it works, but the weird thing is, you only need the power on to start the truck, after its running, you can shut the switch off, it stays running, shut it off, you need to turn the power on to make it start pumping again, now who can explain this??

SOURCE: no fuel??

bad advice.
on this car , the fuel pump relay above knees ,green socket
energizes for 3 seconds only at key on.
this pressurizes the lines.
then when cranking the pump runs full time.
then when running , it runs full time.

I have a bench test jig for this ECU and that is exactly how it works
and so says the FSM.

this being an 8v engine (you didnt say) there is a test port onthe
the left banjo fitting of the fuel filter , a 6mm bolt. 10mm head.
remove it and put on a fuel pressure tester.
about 30 psi.
you must bleed the pressure off before connecting.

in your case, outdoors no smoking.
lots of fresh air.

Check the fuel pump relay

Buy a new battery.

Hi and welcome to FixYa,

On most Suzukis with fuel pump that I have worked on, the wiring would be:

• Yellow/Green - start interlock, connected to the clutch lever position switch and/or starter control relay;
• Black/White - ground;
• Orange/Yellow - ignition B+12; and
• Black/Yellow - trigger pulse, connected to the - terminal of one of the ignition coils and/or to the CDI/igniter.
