2.0 hdi xantia won't fire

Thats it! You need a decent amp?? Relay, am prety surr mine was a 70amp one, picked it up at the auto sparks place with all thje wire and bits, made a good amount of diffrence to the starter! Whilst at it, I also cleaned up the multi plugs in the engine bay and earth points too,

and it says a faulty injector will show air bubbles at its leak off whilst cranking...ive just tried this and 2-3 of mine are doing this
does this sound right to u guys?

[taffy]

another thing where is the gauze for the crankcase as i think its blocked?

[taffy]

well new battery and 4 working injectors later and still no start
battery was defo shot for starters as it spins over lovely and consistantly at good pace..its an exide pro 62amp..smaller then my old battery but i went with it after reveiws and so far im inpressed..as ive now cleaned all earths and connections..stripped and rebuilt starter motor...i know that atleast the starter function is surfice for more trial and error lol..well had 4 injectors off a 307 which were guarentied working so fitted and bleed and still no fire..code p0190 still there...and heater ciruit ..will have lexia soon and get to the bottom of this as im due a boy in feb and hes gona need running about

this is an interesting post as he had same voltages as me to the fps..5v 9v and 1.5 and the cam sprocket woodruff key had snapped!
how would this show on a lexia and how couse i check without removeing the cam sprocket(getting board of removing timing belt now booo)
i take it the camshaft would still spin?
would it just loose its timming?
wouldnt it break a rocker?
thanks again guys

[citroenxm]

YES if the Cam timing is out it WILL break rocker fingers...

I dont think a lexia will help you. Have you had the crank sensor out and cleaned/replaced it?

Hows the Cam sensor?? If its been distured and PUSHED too far towards the cam shaft pully it will destroy the end of the sensor.. There should be a little "Notch" sticking off the end of the cam sensor.. and the locating hole on the sensor SHOULD NOT be right over to one side... the screw should be about central.

[taffy]

yea i think il get the rocker off morrow and have a look
yea ive put a new cam sensor on it and set correctly..ive also found that too lol easy job to mess up really

[taffy]

if im getting 9 volt from an ecu earth to sensor where am i looking for the short?theres alot of earths going to the ecu...

[taffy]

ok better way to ask is what is 9v when key turned on? i also have p0380 but i also see the earth for the fps is same as the boost pressure sensor?

this is exactly same as me gona try this temp earth to the fps

[taffy]

well no...my earth to fps is fine..my signal is 9.14 and power is 4.95...must be ecu

[taffy]

taken ecu appart and cant see nothing untoward...the silicone was still tacky lol after 14 yrs...
my ecu is a bosch edc15c2

[taffy]

well lexia3 on route lets try and get to the bottom of this!!

[taffy]

well ive finally got me lexia working and ive fallin in love with it
i got it working on an ancient laptop (compaq m300 lol!)
well the perminant fault codes are
fuel pressure sensor..short to positive or open circuit
glow plug unit...short to positive
problem is ive checked the circuits exept ecu...
what would cause the signal in on ecu to be reading 9v out?
thanks for ur help
