hyperfocal 15-06-2006, 06:31 hi just bought a 220sdi 98 from auction and limped home at a max speed of about 25 mph car seems to die when revved and smokes starts fine /tickovers fine any ideas many thanks E_T_V 15-06-2006, 13:07 Disconnect the MAF and the EGR valve (a forum search should reveal all on this). If it still does it then check wiring to number 1 injector for chafing. Also check that air isn't getting into the fuel through a loose bleed nipple or fuel hose connection or even the primer bulb. Those are the most common faults. E_T_V 15-06-2006, 13:11 Oops almost forgot, another slightly stranger possibility is that the brake lights are faulty. (when the brake lights are on the fueling is cut from the engine when the revs are above 1200 rpm). 200's are known for faulty boot hinge wiring causing all sorts of weird and wonderful electrical problems so this is also worth checking - peel back the rubber boot to reveal all those frayed and broken wires). AndBurG 15-06-2006, 14:09 also check your boost hoses as they can cause this ussue if they are split Rover_ron 15-06-2006, 15:02 In addition to the above suggestions, check for collapse of the intake hose - the one from the bottom of the air filter housing. Look/feel for kinks in it. Its going to be one of these. hyperfocal 15-06-2006, 16:04 hi just bought a 220sdi 98 from auction and limped home at a max speed of about 25 mph car seems to die when revved and smokes starts fine /tickovers fine any ideas many thanks tony tried all these no joy but havent changed the maf also can only rev to just under 3000 then loses nearly all power and smokes a lot also should the diesel injection pump buzz all the time even with the engine stopped and the ignition switched on/doesnt seem to be the solenoid as disconnected and still did it starts and ticks over lovely thanks Rover_ron 15-06-2006, 16:07 tried all these no joy but havent changed the maf also can only rev to just under 3000 then loses nearly all power and smokes a lot also should the diesel injection pump buzz all the time even with the engine stopped and the ignition switched on/doesnt seem to be the solenoid as disconnected and still did it starts and ticks over lovely thanks Its definitely an air supply problem by the sounds of it. I'll bet there is a split in the bottom intercooler hose - right on the elbow. I'd recommend taking off both hoses - splits are hard to find and only open up under pressure. Ron hyperfocal 15-06-2006, 19:08 tried all these no joy but havent changed the maf also can only rev to just under 3000 then loses nearly all power and smokes a lot also should the diesel injection pump buzz all the time even with the engine stopped and the ignition switched on/doesnt seem to be the solenoid as disconnected and still did it starts and ticks over lovely thanks just taken off intercooler hoses both seem fine/refitted and still have problem any ideas E_T_V 15-06-2006, 22:41 Also check that air isn't getting into the fuel through a loose bleed nipple or fuel hose connection or even the primer bulb. Did you check this. It could be something as simple as air getting into the fuel. Try running it without the intercooler hose connected (temporarily obviously). This will rule out turbo problems. hyperfocal 16-06-2006, 07:29 Did you check this. It could be something as simple as air getting into the fuel.

This will rule out turbo problems.turbo seems fine whistles when i rev hyperfocal 16-06-2006, 10:25 just changed the intercooler and pipes all good condition no change this is driving me nuts picking up new maf this afternoon thanks for all the advice everyone tony AndBurG 16-06-2006, 11:13 wont be the maf, not on a 200, get a cheap boost guage and check its boosting right, could be problem with boost spikes/overboosting/underboosting. replace the fuel lines in the engine bay, if any of these are letting air in the car will run like a dog, I'd change the fuel filter aswell hyperfocal 16-06-2006, 19:08 cheers for the advice just done this test run the engine pumped the primer bulb which was soft and engine run fine with no smoke /stop pumping the bulb which went soft and same old problem any chance it could be the turbo? E_T_V 16-06-2006, 19:24 Sounds like a fuel lift pump problem or air getting into the system (usually via the priming bulb or the fuel filter seals). Turbo won't be affected by the fuel. If the turbo lets go you'll get lots of blue smoke, and I mean lots of it! hyperfocal 16-06-2006, 19:53 cheers im new to these engines where is the fuel lift pump Rover_ron 16-06-2006, 19:56 cheers im new to these engines where is the fuel lift pump Its built in to the end of the injection pump so not accessible or replaceable easily if at all. It doesn't usually cause a problem, so have you eliminated air leaks and replaced the fuel filter. Ron hyperfocal 16-06-2006, 20:07 replaced filter and will check pipes tommorow many thanks hyperfocal 16-06-2006, 20:21 just a little question my diesel injection pump buzzes is this normal? E_T_V 16-06-2006, 23:23 Yup its normal. If air is getting into the fuel the most likely place is the priming bulb on the fuel line. hyperfocal 17-06-2006, 06:03 cheers will check today pquinton 03-07-2006, 06:22 200's are known for faulty boot hinge wiring causing all sorts of weird and wonderful electrical problems so this is also worth checking - peel back the rubber boot to reveal all those frayed and broken wires). Had that on mine, but it didn't effect the fueling, it knackered up the central locking and blew the relays in the Lucas 5AS ECU... Phil. | |
