c15 cold start problem

Postby c15 sumpscraper » Sat Oct 08, 2011 7:15 pm

Hi guys

i own a c15 van the newer model with the DW8 engine.

now im more than sure before i got to see the van, the owner had started it before i got there as it more or less fired straight away and ran spot on.

as when i came to start it in the morning it just wouldnt fire, letting the glow plugs go out etc.... sometimes even 7 times :cry:

when it fires sometimes sounds like a knocking then runs perfect,i could leave it for 4 hours go back to it and would fire first click with no probs. but leave it any longer and would it hell as like want to start. its got around 105k on the clocks and only 3 owners.

ive changed the glow plugs, and checked for air leaks etc....and still the same only now its flattened the battery.

for one week last week tho it started and ran spot on then developed the fault again, only to not start attall, my bruv had a look while i borrowed the car to go to work and told me there was liquid around the pump, are these common for diesel pumps to go at this mileage? and could this cause this problem?

Ok , the problem with your C15 will be one of two things, either the glow plugs have failed again, (were they good quality). Possible as you say the fault was cured initially.
Or your valve clearances have closed up due to valve seat degradation. The later is extremely common on these engines , usually after a few more miles though.
If this is the case the valves will require re-shimming, this is quite a job.

I recall Lighty mentioning that valve seat thing a while back
hopfully he'lll give us a bit of a write up sometime?
It sounds a bit of a chore but its best be forewarned and ready just in case

If it isnt that, I wonder if the glowplug relay is actually feeding the plugs?
( assuming theyre OK)
they need quite a bit of current and any pitting or oxidisation on the contacts
or poor connections or broken conductors in the cable etc
could limit their peformance.
Just cos the light goes out doesnt mean theyre actually getting hot
You can easily check for voltage, but thats only half the story and you''d need a chunky ammeter to
check the current as they're connected in parrallel so you may have to pull them and test each one individually

Intermittent faults always suggest electrical problems to me
valves or pump (mechanical) problems dont fix themselves
so I'd be taking a close look at the glow plug system

^^just what i were thinking tbh, was even thinking the ignition switch could be at fault, so gave it some WD, ive checked the relay and plugs etc.... and all seems fine :roll:

shall see how she goes

When I first got mine the guy told me it needed new glow plugs and
it just didnt want to start until I fitted new ones
now its a good un !
I know you've fitted new plugs but my guess is its possibly related to that
due to it being so intermittent
I doubt its the switch as the starter spins the motor
and unless you have a particularly low cranking speed which could be starter motor
related, thats a bit of a red herring IMO

I suggest you whip off the rubber pipe on the manifold as well and check to see the position of the EGR
related flap
If its jamming shut, this will reduce the air getting in
Feel free to disconnect the MAF and stuff as well and ignore the engine warning light
Its a mechanical pump and all that EGR stuff just clogs the pipes
Check for fuel leaks as well as
any fuel getting out means air can get in.

I had a c15 in this week with a slight leak from the diesel pump body only when it was cold, which was allowing air into the system causing non start issues.
The fault was more apparent when the vehicle was parked nose first up hill, as the air in the system allows the fuel to drain back to the tank.
It is worth priming the system using the hand primer before trying to start the van to see if this improves it's starting.
But if the pump is leaking then it will need to be overhauled by a specialist.
