The glow plugs are getting hot now but it is still not starting could the engine coolent temperature sensor have anything to do with it?

[rustym95]

pull the MAF off and see if it starts.

If you have hot glowplugs, then your starting fault lies elsewhere.

11V at the glowplugs was not great though, enough to fire them up, but would suggest to me that the battery may be in a low charged state - would certainly not help matters !

[andy4775]

Yes because it has 11 volt written  on the side of the glow plug

[andy4775]

pull the "maf" off, what is that and where will I find it?  I just new to these diesel engines

[rustym95]

mas air flow, black plug after the air filter,

[andy4775]

when I pull the MAF off what will that do or tell me?

[rustym95]

Maf is the temp control if working tells the ecu what the temp of the air is, if not dont tell the temp, just un plug and see.

[andy4775]

ok will give it a try and get back to you.

Ah ! Point Taken !
Most cars use 12V ones, and as I am not an Omega owner, I am not aware of some of the subtle differences - however, if there are mutliple glowplugs fitted, Some cars have one, some have one per cylinder, then its worth checking all of them to make sure that they are ALL working - failing that, I think have a listen to Rusty and go down the MAF route next

Any fault codes ?

 

[andy4775]

No I unfortunately I don't have any codes Dave.  The old plugs I took out were the original plugs and they were 11 volts also.  I am just waiting for the battery to charge up and I will give it a go with this MAF disconnected (just at the plug).To take the MAF out (If I do have to change it) has some weird looking bolts, what do we need for them and any idea how much they are?

[andy4775]

Dave I did check them all and they all had 11 volts to them.

[rustym95]

what bolts on what, if you mean the MAF you need a new unit, they dont come seperate.That is if the MAF is a fault.

[Dave DND]

Dave I did check them all and they all had 11 volts to them.

Personally, I would remove each one and check that they are getting hot, as its the only way to determine that each one is working.

From what Rusty is suggesting regarding the MAF - just unplug the black plug and see what happens.

I think at some stage you will need to have some codes read to see what is or isnt going on

[andy4775]

Took the plug out of the MAF and it made no difference at all, Dave I will take each individual plug out to see if all of them are getting hot, how is the best way to check them?
