Engine codes ECN 068304, ECN 070406

Question

Carried out pedal test on Astravan and shows above codes.

Have purchased 4 new glow plugs as was advised that this was the problem but have been unable to remove old plugs so far. Just wanted further advice that this is the actual problem before I get back to work.

Any help as to how to fix these problems much appreciated.

ECN 068304 Glowplug circuit open or low volts

Measure the voltage is what the first step should be for the glowplug
