P38 starting problems

[shaunm41]

Defo interested mate. Drop me a pm let me know what you would be happy with and will go from there. Can pay by PayPal if we reach a deal.

Have you sorted your issue yet?

Just solved a similar cold start problem , sudden onset , turned out to be mouse had nibbled part thru spill pipe under the air trunking pipe that goes over top of engine , took a bit of finding as I had replaced the spill pipes a few months back and all the others were perfect !!

This is the fueling info I'm getting.. Anything look untoward?

That's at tick over.

Ps

I'm getting air temp reading of -38.88

I think you've just brought Datatek out in a cold sweat.

I believe that is the reading from a sensor that isn't present.

G~

Lol

I'm assuming that's the maf?

If so I'd assume its slightly faulty?

If you have a MAF, that temperature reading is normal as the sensor does not exist, it does not mean the MAF is faulty, although of course it maybe.
From memory, the swg set point and actual should not be that far apart and the modulation looks high but it's a long time since I looked. I could if it would help post screen shots of mine if it would help to compare but not until late tomorrow at the earliest.

Yeah it's got a maf. So that's not an issue then. But the points do far apart is an issue?

Could be, I do not know without checking as FIP's are not my speciality, I just don't remember such a big difference in the readings.

 

[shaunm41]

Some pics to compare would help a lot

Thanks

I could be wrong but I am sure Wammers mentioned timng modulation should between 40-55% but don't quote me on that!

Perhaps he will come along and clarify. I'm assuming if that's correct a new timing chain fitting would correct that?

A timing chain would be good, but it is also possible to retime the pump (aslong as the chain hasn't stretched excessivly that is)

Don't forget if you fit a new chain etc, in 20K you'll have to retime the pump in anycase!

Well it's done 76000 and have no history so I have no idea wether this has been done or not. How difficult is it to retime the pump? Worth a try before buying a full timing kit

 

[Saint.V8]

It needs locking pins and a Dial indicator to measure the cam lift inside the pump...procedure is in RAVE manuals...measurement is in the thousandths of an inch!

I bet a garage would charge a small fortune

IIRC I have heard figures of £250 or so for a Diesel Specialist to retime the pump...

:-o

76000 is nothing for this engine, I have one on 162k and the other on 112K and the timing is fine.

Well the cold starting seems fine with new battery. I just give it a few heats first and it fires after a few cranks. So if I refit the hot start fix I'd imagine it will be ok...
