bosch vp or vr inj pump

[pug306driver]

    Thanks ruan, similar but different, has 2 wires ( with 2 wires in sleeve ) rather than the one wire in the picture. Have pump id plate info and picture, will try and post picture now. Its a Japanese made bosch

Managed to get a dtc code finally, Nissan code 0704 which is an obd code of 1251 from memory, spill volts circuit.

info ( Poodle posted lots of 306 info as well as some test books, the brown covered one auto tech, exploded view of the vr bosch pump internals, really really usefull info, really well done dude !!!!!!!!!! ) suggests ( a ribbon cable in an inj pump ?? bloody hell, video camera problem was ribbon cable to flipout screen, ribbon cable UNOBTAINABLE FROM PANASONIC, so camera scrapped for sake of 20p ribbon cable, hah!!!!!! ) ribbon cable to cam ring and spped sensor inside inj pump, progesss, my arse !!

Spill control seems to be the solenoid controlled needle in the centre of the pump.

Lads doing some more research for me now.

am printing this info now for reference, as well as the exploded view to looksee and check.

so there is a ribbon cable in there, and drive is taper and keyed.

looks as if the spill solenoid may be a replacement part?? some more research needed, but going home to do test for spill unit power and earth on inj pump.

thankfully an inj pump can be removed/refitted without having to take the engine out. A special tool will need to be made to stop the inj pump sprocket falling and buggering to initial chain timing/chain auto adjusting, else its engine out. A real pita of a job.
