Thread: 2.8 hilux injector pump fitted to 1kzte

Iv got a 1kz that had the dreaded electric computer powered injector pump
It's ran with a chuf and occasional shake at idle and generally ran not the best
Iv just fitted with the help of a mate a 2.8 hilux manual pump to get over this issue, with the new pump on it runs better but I can see the issue is still there, anyway it's mid project and I'm really curious to know what the plug on top of the 2.8 injector pump is with the two blue wires?
It's obviously not critical as I'm able to drive the truck but it's doing a couple of funny things that I'm thinking I might be able to remedy if I know what it is,

Some of the odd things
Runs for 3-4 seconds after turning off the key then shuts down
Bit hard to start like there is air getting in the feul line somewhere(did this with the old injector pump too) Will chase this down with clear tubing

Any help greatly appreciated
