I have a 2002 Land Robert Discovery that won’t start. No spark to plugs. Changed the crankshaft position sensor and it has new coils, plugs, and wires. When I try to start I get both transmission lights flashing “M” and “S”. No check engine light. Was running fine then one day wouldn’t start. Any ideas?

 

Here is some background info. Car was having a hard time starting and I suspected the fuel pump (several times my Gas gauge failed to register anything in the tank on a full tank of gas). I replaced the fuel pump and it started on first crank for 2 days. Then nothing. Checked and have no spark at plugs. Beginning to think it wasn’t an issue with fuel pump after all, but maybe another issue. Replaced crank position sensor and still nothing.

 

Have you checked the inertia switch? Scanned for immobiliser codes? Camshaft sensor? There are a large number of threads on this forum about dealing with no-spark situations.

 

Check all of your mega fuses in engine compartment fuse box and fuses in drivers compartment fuse box and ignition relay in drivers compartment fuse box.

 

I checked all the fuses. Scanning it today. I didn’t realize it also had a cam position sensor. Thanks Everyone I’ll keep checking
