Hey folks. Looking for some advise here. I know I need to run codes and will be doing that tomorrow. Curious what the problem is with my 2004 LR discovery 2. It has 120k and had some slight misfires but was still running great. I ran some BK22 through the tank. Changes all plugs and oil and the service engine light finally went off and has stayed off for a few hundred miles. All of the sudden today it turns over but will not start. I am thinking either coil pack or fuel pump? Would that sound right? Any thoughts would be greatly appreciated. I am dreeding this could be something worse and cost me tons of money. I love this truck but worried I cant afford to repair it. Thanks a ton and happy 4th.

 

I would bet it's your Crankshaft Positioning Sensor. I had a few misfires, then replaced it last weekend and haven't had a single one since.

 

The crank position sensor sounds like a likely candidate. If you have a scan tool with live data, you can turn the engine over while watching the rpm data pid. If it stays at zero, or looks really erratic it's probably the crank position sensor.
