Need to know if its a Euro or USA version.
Need to know if there was any stumble / partial start when cranking.
If not done recently, pull CE, polish, re-fuse.
Same with key grounds.

Injection relay is also costly on these, but replace it if it has any significant age on it.

Heat soak causing movement in wiring can trigger a short in an injector plug, that takes-out all the injectors.

We've seen in the Ljet cars 4 cylinders loose injector pulse with a corroded wire inside brain box leading to the one of the two internal final stage ampls.

We've seen what appears to be heat soak / intermittency with the LH Jet (Euro S2) when there is a bad Crank position sensor.

I now always replace all sensors, fuses and key relays when resurrecting one of these cars, along with fuel pump and clean all grounds. Lot less frustrating.
