Engine had broken the timing belt, bent 6 intake valves and broke 6 rockers.
Have replaced all 16 valves, lapped in, stem seals, timing belt, head gasket. Cleaned lifters and primed with diesel. Tried to start, no go. Check fault codes with X431 Pro Mini, crank angle sensor faulty, replaced with new, still won't start, starter was sounding bad, replaced with new, replaced all 4 injectors as the old ones were filthy and no-one cleans them in present country. Everything comes up fine with DTC's, all clear and can see engine crank speed, mv pulses injector etc, fuel pressure 385kpa. Took spark plugs out and coils, earthed plugs, yellow spark on all four. Has me stumped?

We need three things to start a gas engine (fuel, spark, compression). However, we only fuel and compression for a diesel engine so it appears you have repaired everything but we don't know what the compression is in the engine. Let's start with checking for compression. We don't have a manual for this vehicle as it is not offered here in the USA but I suspect we still have a compression issue which is why you are not getting it to start.
