Recently changed my glowplugs, 3 out of 4 were dead however i seriously cracked and broke some parts of the harness doing so, issue was fixed for a couple days, but then rough cold starting came back, figured it was the harness so ordered a new one, however im getting no power through the wires of the harness so no point in wiring the new one to it, fuses ontop of battery are fine, the coil symbol appears for a split second on the dash when the key is turned, can anyone suggest what this could be,
Thanks in advance
