Rats ate the wiring on my 2008 LR2 - I replaced the wiring harness and now i can't get spark to the plugs. Checked the starter, coil, fuses and connects. Car cranks, but does turnover. The gas pressure looks good as well and their is fuel on the plugs. Is there a reset I can do? the codes only say speed sensor PO500 and HDC shows alert. Nothing else. Help?
