Re: [doc] re new accumulator-now will not start!

["blackaddertoo" <blackaddertoo@xxxxxxxxxxx>]

Hi Martin

thanx for the info.

when i removed the accumulator i undid the nut? at the end of the 
steel line, not the one onto the accumulator.

the old one did give a bit in its clamp (perhaps because of the 
rubber sleeve) and i need need a lot of force on the end of the 
spanner.can't see a kink but i thought could be one the other side 
of the chassis hole.
i can only feel and obviously can feel a bend but pretty impossible 
to confirm a kink. strnage that it would always start cold run 
rough, but could keep revs at 2000 ish then without accelerator 
would slow then stutter, bit of engine shake, then stall. would not 
restart for a hour or so.

but since new accumulator, will not start..
tried last night, it did cough once but did not start. fully charged 
battery. have pushed relays home.
only other thing i could think of, a relay damaged on removal. ie 
the rpm relay. is this a normal bosch as i have lots of them.

i take it the relay marked fuel (lambda). would not actually need to 
be powered up untill the engine warms? and lambda system takes 
over??.

another point-don't laugh but only about a gallon in the tank. at 
what level does the car not like it?? has a specialtauto fuel 
unpdate (tank filter etc.). also new tank, pump, filter line to fuel 
distributor. was going to check the earth at the front frame (the 
one to the pump??)

if i was close i'd book in for diagnostics but live a distance away

a place a few miles away can check pressures etc (bosch specialist) 
but i don't really trust anyone non delorean minded with the car

regards

Steve
