Re: 156 2.4JTD Not starting- thoughts please!
flashing glow plug for 30 secs after startup means there is a fault, but as with many modern diesels, glow plugs are NOT required to start the car.
They are more for emmisions than anything as they keep on after starting for a short time.
My first check would be fuel pump in the tank, can you here it whizz up when ignition is turned on, if not check the pos & neg to it.
There are 4 wires, 2 serve the fuel guage, the thicker other two are the pump.
I bought a 2.4JTD Sw veloce for £250, it didn't start at all, all it needed was an earth to the pump!
