strange faults on my diesel

(1/2) > >>

Hello everybody. My rangie let me down this morning. It would not start. found fault to be all 4 of the glow plugs not working. They were ok friday. Anybody had a problem like this before. Me thinking it was a surge from the batterys as engine was not running or plugs stayed on too long and burnt out

thermidorthelobster:
Which engine?

I don't think you'd be able to get a surge from the battery.  It can provide just over 12v but not anything more.  A surge from the alternator could be a possibility.

However, I think it's more likely that 3 of your glow plugs were already gone, and it's just the last one giving up the ghost which has meant you couldn't start it.

Yes engine details would be good its a perkins 3ltr turbo diesel. True but if 3 of the plugs were not working i would of noticed as it would of been a pig to start. But its been starting great up til this morning. engine not running when glow plugs are pre-heating. Only thing i can think of is they stayed on and burnt out on friday which would explane why it would not start the day after. Just never knowen anything likes this before

PoPrivit:
Hi Chap,

are you sure that the glow plugs have gone and that it's not just lost a feed. you should have a 12v feed from a relay to power the glow plugs. i dont think that you would drop all 4 plugs at the same time. Get your self a good tester an check for a 12v feed and keep following the wire back till you find one.

cheers rich

I check the feed to the plugs got about 12.5v. so tested all the connections with the one spare glow plug i have and it worked on all the connections.only thing i can think of is the plugs stayed on for to long and burnt out. As the car started normally on friday went to sart it this morning and it would not start. ruled out one or two  not working over time but think i would of notice this as the car would be hard to start and up to saturday morning it had been starting normal. And i have never heard of 4 plugs going at the same time. very strange
