Hi, I'm only getting 9v at the glow plugs. Since I put new injectors in, it's become more difficult to start. I changed the glow plugs too.
Apparently there's no relay in the system so does the power come straight from the ignition switch? Is it worth fitting a relay?
Any ideas welcome.
Thanks.

maybe a bad earth, do you have 12v at battery? keep following it back
- battery
- switch
- follow to plugs
 
Yeah, battery's good, turns over fine, just takes a lot longer to catch.

But do you have a good strong 12v at the battery? You're losing 3v somewhere so this fault needs to found first. Crack open and clean earth wires first, replacing any poor/high resistance wiring first. Once earth/s are 100% proven, then trace back from glow plug feed wire.
 
There is no relay, the ignition switch is of a type designed to take the load. Connections in the switch could be worn causing resistance but check items above first.
