rangerover p38 starting problem

seajay · Feb 19, 2012

Hi There I am new to this site so sorry if I am in the wrong place, I have a problem with my p38 range rover, I was driving it the other day and it just cut out on the move and now wont start, I have read other threads about becm/ecu's going out of sync can this happen on the move? the battery is buggerd and needs to be replaced so that may have caused it although it started that day ok, there seems to be fuel coming up to the front ok.
Has anyone got a syncmate near me in tamworth staffs if needed to try ?? I love this car but it does have some silly niggling problems, i never had all this with my old landrovers !

oh and its the bmw diesel

Never heard of one going out of sync when running.More likely to the CPS sensor.Replace the battery first as these vehicles dont like dodgy elect

rics.

More than likely the Crank Position Sensor as JohnP38 mentions....

First step is to fit the biggest battery that will fit, 135AH 1000CCA fully charged and then see if you still have a problem. Low battery voltage is a killer with all the ECU's in a P38.

ok thanks first step a new battery I think, would a cps sensor just pack up like that ? the car was running fine with no warning lights on.

They can indeed....

They can, but a duff battery can produce all sorts of strange effects. Don't jump to conclusions until you have sorted the battery.

ok I fitted a new 105ah battery today, my local auto electrician said leave the car for half an hour with the battery off then put the new one on and it will sometimes then re-syncronise from the key fob anyway thats what i did and it fired straight up

Now i have just got to sort the air suspension that is stuck up in the air but I was having trouble with that anyway, it goes on to high when your driving then wont come down again....any ideas

thanks again all for your help

Bad connections/earths in the EAS box, blocked exhaust filter on the valve block, duff driver pack.

JohnP38 · Feb 25, 2012

Could also be a defective height sensor or connection.

seajay · Feb 25, 2012

yes a local dealer has told me to check the height sensor conections, its had air springs all round and i rebuilt the valve block with new seals and diaphram etc and exhaust valve, I had wonderd about the drive pack myself, what i dont get is when it goes up why it wont come back down sometimes it takes hours, i also thought about the exhaust solenoid, oh well.....cheers

If the driver pack is not operating the valves it won't come down, but it could be you have made a mistake rebuilding the valve block.

seajay · Feb 28, 2012

Yes the drive pack might be an issue as you say, anyway they can be tested ? No i didnt put the valve block back together wrong, I spent many years working on hydraulics so am quite fussy about stuff like that

will get under this weekend and get the sensors off as well to check the connections funny thing is it plays up worse when its wet so think it is a connection issue

Dont be overconfident that you did not make a error rebuilding the valve block!.It has happened to many an experienced person that they have.You wont be the first to believe this and be wrong ,nor will you be the last.:5bbeatdeadhorse5:

cheers I will check it all out anyway

Wasn't there somebody fairly recently who managed to fit the exhaust diaphram backwards?

seajay · Apr 10, 2012

Just for anyone who may be interested, the fault on the suspension turned out to be the drive pack ! I have changed this and all now seems fine, oh and yes I checked the diaphram and i had put it in the right way !!

cheers all for your advice
