Update --> Going nowhere fast.

Put a LOW power bulb in each injector and they're all pulsing like they should. Plugs are all wet. Spark on all 4 plugs. Changed back to old plugs which were gapped by MSD.

Changed CTS, DPS and ACT sensors. Car still won't start.

Resistance of CTS in car with loom disconnected was 7.8k Ohms.
Changed CTS, disconnected resistance is 6.3k, connected now it's 8k.

ACT resistance disconnected was 7.6k.
Changed ACT, disconnected resistance is 7.4k, connected now it's 8.5k.

It's freezing, well almost. It's 5 degrees outside temperature here in the southwest of Ireland and getting colder.

All engine earths removed, checked, cleaned and reinstalled.

All sensor plugs are connected correctly and seem ok.

All timing marks checked and all check out ok.

A q in an earlier post:

do all relays work properly[not just click]? --> How do I know if the ECU and fuel pump relay are working correctly like you ask? I presume they both are though as injectors are pulsing and fuel is being fed to rail and when cranking, fuel pump is on constantly.

Doing a continuity check now. ECU diagram from big turbo.co.uk just to see if everything from engine is connected to ECU hairbrush plug like it should be.

Really can't think of anything else.

Anyone got any ideas?

Maybe time to rip off the rocker cover and check all valves are opening, cam isn't split etc?!! A cam has broken on me before on the rolling road just after a new build ffs!!!

Please help, cheers
