Replaced injector pump 990 David brown original had ceased now tractor starts runs for 20-30 seconds then dies. Restarts fine but only runs for 20-30 secs. First start in morning ran for 2-3 minutes

it indicates that there is a fuel shortage problem
check the supply pump for fuel supply to the pump elements
if the fuel supply pump is part of the injector pump , there could be a blockage in the fuel line or air still in the system
of there is a good supply of fuel to the pump then contact the shop that reconditioned the pump
if you just fitted another pump without reconditioning it , then talk to an accredited diesel pump specialist shop

Is their a fuel pump inertia switch or a reset switch on a 1999 Kia shortage 4x4? Not getting power to pump..

No , no inertia fuel cut off switch . Check fuel pump relay in the under hood fuse box , also check fuel pump fuse 10amp located in the passanger compartment fuse box . Also if the PCM - engine computer doesn't see an input fro the crankshaft position sensor it won't energize the fuel pump relay . So check for spark too , if you don't know how , there are videos on youtube . You can also check out a wiring diagram for fuel pump electrical circuit at

1999 Toyota camry. Automatic trans. Blows fuel pump fuse when shifting into drive. Checked wiring. What else can it be?

Robert: According to " I agree it may not be your fuel pump. You can access the pump under your back seat, underneath the cloth under there. You will iummediately see the plug and the screws to open the little hatch. My 1986 Camry also has a problem with not getting any fuel and thought it was the fuel pump. turns out I keep blowing my efi fuse so i unplug the power wires to the fuel pump and it still keeps blowing the 51a efi fuse. So we have narrowed it down to being an electrical problem. We think it is a shortage or a bad relay. So do not instantly run out and think it is your fuel pump. If you are blowing fuses unplug the power wires to the fuel pump and try to crank the car if the fuse still blows then it is not a bad pump, if it does not blow then there is a shortage in the wires in your fuel pump. Hope this helps I will let you know exactly what the elctrical problem is in my car once we do a complete run down."
