Glow plug light and loss of power

[Johno1920]

I had an issue earlier in the year and changed my fuel pressure regulator, this solved the previous issue, however since changing that i've been having a problem with the glow plug light coming on (only on higher revs) and a loss of power, turn the car off and back on and the car seems fine again, the car drives fine in and around town, car starts 1st time every time and this issue only started when changing the regulator, drove great before.

I do have a thinkdiag+ and im getting codes p067100 and p067300 cylinder 1 and 3 glow plug circuit.

Has anyone else had anything similar happen and how did you solve the problem? Am i looking at changing the plugs? Or could it be something else.

Any help would be great.

Thanks John

Hi both codes are glow plug related and I think the fuel rail pressure sensor fitting was coincidental to the problem you have now.

Cheers for the reply Steve, i was thinking the car would struggle to start with a glow plug issue?

i think i may as well start with changing them and go from there.

Hi no the only time it will struggle to start is in cold weather but generally speaking they will start anyway when the plugs are knackered because the fuel rail pressure is so high.
