Now thats funny!

Hello,Firstly i would like to thank everybody for all there ideas and help for the hydraulic problem on my 3.9 v8,i took the rocker covers of to see if the cam or chain had snaped but it had not so all ok there,i then checked the injecters all ok there,i checked the wiring harness again could'nt find anything wrong there,the more i tried different things i noticed petrol was now coming out of the spark plug holes on the left hand bank of cylinders,sorry that i did'nt notice this before guys(very sorry steve_d ) .so i started striping the engine down to investigate what the hell was going on,starting with the plenum chamber and ancillarys,as i undid the vacuum pipe on the back of the plenum chamber,fuel poured out of the plenum,i turned the ignition on and fuel came out of the regulater via vac pipe,so top prize to Ally V8 .unfortunately for me all this work was done on a saturday afternoon Ha.

Hello everybody, sorry i hav'nt been on for a while but i have had nothining to report on the range rover front since my last posting(my range rover keeps dieing)after taking up the advice of you good chaps,checking/messing about with the fuel injection/engine wiring harness my range rover had continued to run and perform superbly(must have disturbed somthing)UP UNTIL NOW.I set off in the range rover like normal got 200 yards down the road and it just cut out so i tried to start it with no luck(i thought its back to its self,keeps dieing) on the 3rd atempt of trying to start the engine it just stop dead and would'nt turn over,after thinking the battery was flat and changing the battery it was still the same so i tried to turn it over by a socket on the crank pully,i could not turn it,so i thought i would take all 8 spark plugs out to make it easer to turn the engine over,as i started to undo number 2/4,6,8 spark plugs petrol started spraying out under pressure,i then undid the odd cyclinder bank spark plugs and this side was all right,i then turned the engine over with the crank pully and it was free,so i turned the engine over on the stater motor(with spark plugs removed)it was like a water fountin feature with squrts of petrol coming from the spark plug holes on #2,4,6,8 but none on #1,3,5,7.After empting the cylinders of petrol i put all the spark plugs back in and tried to start the engine,it cougthed and spluttered and then locked up solid again,so i took #2,4,6,8 spark plugs out and they was the same again(petrol spraying out under pressure)i turned the engine over to clear the petrol out of the cylinder bores and tried again it did the same again,it seems to me that the injecters on the even bank of cylinders are staying open all the time so i check the wiring harness for a short but could see nothing i also changed the e.c.u(again)just incase.i was wondering if this has happend to any body else and has any body got any ideas why this is happning,can somebody please help me before it sends me insane.

Hello again every body,i have managed to get around to checking the earths,a few were a bit rusty so i cleaned them up and made sure the others were alright.Tried wagling the wiring about(engine harness/low tension)while the engine was running and it just kept on purring away,not had a look at the ignition switch yet so thats next on the list,went out in it yesterday and did 35 miles it never missed a beat,iv had a look at the hotwire diagnostics in the archive and come to the conclusion that while the engine is running alright the diagnostics check would come out right, iam proberly wrong on this,i will have to wait untill it cuts out again and try.Thanks again for all the sugestions

Hi,iam not 100% sure but i think its the coil or dizzy,i just cant rember which.

Hi,thanks for the reply,i will give it ago asap and let you know,i was wondering if anybody knew the standard settings for the airflow mixture screw and idle screw i cant find any information on them anywhere,i know this is not causing my problem but i would like to put them back to where they should be,thanks a lot

Hello,thanks for the advice,its one that i have not tried,i will give it a go asap,the range rover only has the standard anti theft device but i dont know anything about it,like how does it work,how does it stop the range rover from being stolen i was wondering if it was going faulty and causing the problem,but like i say i dont know anything about it.does anybody know what the standard settings are for the air flow mixture screw and the idle screw on the 3.9 hotwire fuel injection, somebody has messed about with them in the past and i would like to put them back to the standard setting,i cant find any information in the mannual,i would certanly appreciate it,thanks again for all the help

Hi,i have had the same problem my self with a 109 when i fitted new after market wheel cylinders and britpart shoes,in the end i did a bit of grinding of the steel part of the shoes on the ends where they go in to the wheel cylinders(piston side),if you take about 2-3 mill off the steel and keep the same profile it narrows the overall diameter of the shoes,helps them line up better and allows the drum to go back on easeir,O.E parts are best but the price and availability are not.

thanks for the reply,are the webers really that bad on fuel ,i forgot to mention that i have change the ignition amp, will have a look at #2 surgestion,i have changed the fuel pump and relay all to no avail,will keep trying,thanks

thanks for the reply,i forgot to mention i had changed the ignition amp on the dizzy(yet another part ha!) but iam not sure about the one under the coil,i will investigate

Hello every body,another new boy to the forum, can somebody please help me before my 1991 range rover 3.9 v8 (non cat) puts me in a padded room, the problem i have is this,it stops runing when ever it feels like it,it will run for weeks or it can be days,hours, the engine just cuts out and won't start again for at least 20 mins then it can run ok for the next 5 mins then cut out again or it can run for the next week/month before doing it again,it is very intermitent,it mostly does it when coming to a stop at traffic lights or juntions,the rangie is a mint low milage(67,000) automatic,non airspring model,when the engine does cut out i check for a spark right away and there is always a healthy one, (changed all ignition side (coil,plugs,dizzy,cap,rotor arm,leads,ect)so this leaves the fuel injection side,i have changed the ecu(twice)the main relay the fuel relay,the airflow meter,thepetrol temp sender,water temp sender,the fuel pump,(twice)disconected the speed transducer,changed the fuel filter,the thing is when the engine is running it runs like a dream,pulls like a train,it can do this for 200 miles or do it for 5 miles then it cuts out and wont start again unless left for a short period of time,also fitted new fuel pressure reg and checked all conecters,can some one please help me,i dont want to get rid of the range rover as i love it i also dont really want to convert it to a webber 500 carb but if needs must,any one got a cheep one for sale Ha!
