2000 discovery 2 4.0 bosch engine 197,000 miles.

Recently had no spark condition causing a no start
replaced crank sensor, cam sensor, oil pump gears, timing chain, cam gear, crank gear. Turned out to be a bad interior fuse box on the circuit powering the ignition coils.

Vehicle starts but runs a little rough and check engine light flashes and p0340 set crankshaft position sensor fault/valve timing and multiple catsylist damaging misfires. Codes come back instantly after clearing them..

This is my first time doing timing chain and beleive theres a possibility that I did not get the timing right. On the other hand On pro demand the first thing that shows up for p0340 is I could have received the wrong cam gear for a gems engine instead of bosch.

 

If your timing is messed up, you may have irreparably damaged the valves, valve guides, piston crowns, or other internal parts.
I would go back to #1 TDC and reinstall the whole timing assembly. If you suspect that you have an incorrect part, triple check it before reinstalling, and verify your crankshaft and camshaft positions before installing the chain. Pull the plugs and turn the engine over manually to check for interference, and check to make sure the campshaft and crankshaft position sensors are installed correctly and securely plugged in. The crankshaft position sensor has a spacer on it that will cause errors if it's not placed properly.
