306 diesel turbo ignition stuck on & solenoid stuck open

i have a 306 xrdt, when i reconnect the battery it's as if the ignition is
stuck in the on position
the orange pre-heat light for the glowplugs doesn't come on but the car
will start
the red STOP! & little oil light thing are on, when i start the car they
both go off, when i stop the car they come back on
i can turn the key off & remove but engine is still running, i found the
lever for cutting the engine out
i read the below post from feb this year, the bit about the 12V feed from
the car not going off with the
ignition seems to be the problem that i have
how do i check & fix this?

HI

I have a '93 Rover 418 TDI that has the Peugeot sourced XUD-9A Diesel
engine fitted.

Yesterday the car wouldnt shut off despite taking the key out. I now
stall to stop. I figure it is the fuel pump solenoid being stuck open
and
not closing off.

Do I hav to get this replaced or can I somehow take it out and repair or
use WD-40 to free it?

Any further advice gratefully appreciated.

Cheers

reply:

If you look at the back of the pump, just above the 4 fuel outlet
pipes, you'll see the solenoid. It has the crimp terminal fastened to
the top with a small nut. It can be a pig to get at and need some of
the bracketry removing. Once off, it's a very simple device. The
plunger itself is in the diesel so wd40 is a waste of time. Before you
remove it, check that the 12V feed from the car is going off with the
ignition. You don't want to waste a lot of time with the plunger if
it's not the problem.

yeha

 

check the cooling fan connector (ns of the rad) it usually melts into one
lump
if so just cut it off and solder the wires together one at a time(you may
need to remove the bumper for this)

 

cheers - was the plug & socket
i had smashed the front end & the fan seemed ok & so did the wiring
opened up the plug & a couple of the connecters were bent & stuck
together
all sorted now tho switches off when i turn the key & take it out!
