P38 Diesel injectors leaking?

Car used to start first time without any problems. 6 months ago starting became erratic. Engine turned over but would not fire up. Then tried 3 glow cycles and started up after 10 seconds on the 3rd glow. Lots of white diesel smelling smoke out the back. After couple of months became harder to start so changed battery, temp sensor, timer relay and glow plugs. Didn't have any effect. Tested old glow plugs and they all worked. Then tried 5 glows - this helped for a short while but then car would only fire up after 5 glow if you kept starter motor turning as it tried to fire up - at least 20 seconds cranking. Even more smoke out the back. Then tried leaving 10 seconds before turning stater so pump fully primed. Didn't help much but seemed a bit more inclined to start. Replaced in tank fuel pump. No effect. Then stopped firing up altogether no matter how many glows. Used easy start and it fired up after 10 seconds of cranking. Over last month still struggling to fire up - replaced drain off pipes as it was smelling of diesel in engine bay. Started after 3 glow. Starter motor then stopped turning after 10 seconds. Try again and it starts. Decided to let the garage have a look.

How does it run and start when warm?
 
Chains stretching/stretched?
Pump static timing?
Wammers is about to go into doctors questions with you. This is how it rolls.
Every answer you give will lead to another question and bring you closer to an answer.
Trust him, this is how a good mechanic gets an idea before he even lifts the bonnet!
Good luck and run with him;)

Not playing never mind eh. From his description and if it does run and start normally hot then he needs to be having a close look at glow plugs, glow relay fuse, relay function and connections to glow plug feed cables. .

Time for the crystal ball Tony! He posted it took 10 seconds to start on Easystart:eek: wonder if its down on compression ,it's wonderful stuff for breaking piston rings. How are you today mate, still waiting for the head to come back so I can finish the engine. May fall in love with it again and put the replacement on hold. Speak soon.

A bit better thanks. Depends what it does warm, from his description does sound like glow system problem. Doesn't really matter how good the plugs are if they are not being powered.,
 
Starts and runs fine when hot. The garage are convinced it' s leaking injectors which are letting air in overnight and so engine trying to prime the engine first thing hence difficulty in starting. So I'm going to put in a one way valve to see if that helps. If it does then at least it might be worth getting injectors tested. Or consider taking a punt and getting second hand off the auction site. Can't really justify spending yet more money on a sinking ship!
 
Pull the injectors out one at a time and crank it over.... put an injector in bottle ... see if they all work

If spill pipes are sound they are talking rubbish. The problem is the glow system. Check voltage at each plug, if low or none, take out the glow relay check that 80 amp fuse is sound. Check plug wire terminals and those on the relay are sound and making good contact. Glow relay is in box behind battery along with ECU. Disconnect battery before playing with relay. The white smoke on startup is unburned fuel accumulated whilst cranking without start and NOT leaking injector nozzles..
 
I was thinking because of the white un-burnd fuel there wasn't enough derv going through to fire it up in the first place?
 
Checked the voltage at each glow plug - reading 11 volts with one plug reading 10.53v .

That means the relay is working it does not of course mean the plugs are. Lift pump is powered by number six whilst glows are active.
 
Have you checked the leak off pipe at the back of the diesel pump and the blanking cap on number 6 injector..Also how long do the glow plugs get power before the power goes off ....
