So to set the scene a bit, the trusty old 1.6 engine in my mum's Scenic snapped a cambelt and took all the valves with it, so using good old logic and a bit of inspiration from the Kangoo and Mk1 projects I swapped in an F4R from a ph1 172, there's only 3 other Scenics that I know of with this powerplant in it so figured it'd be something a bit different 
Anyways, I've used the Scenic loom with all the relevant wiring from the ph1 loom I had (coilpacks, vvt dephaser solenoid etc..) spliced in with it, changed all the pins on the Scenics ecu connector to match the ph1 connector and then double checked that all the wires were correct. So, comes to starting for the first time and the engine won't fire, turns out out there isn't spark but there is fuel, as proved by it shooting out the connector to the fuel rail when I pulled it off to check. Searching on here pointed to either the fuel pump relay, tdc sensor or a bad ground preventing the spark, however changing the relay and sensor (new blue renault item) and double checking the grounds for continuity proved unsuccessful. The relay itself does click when I turn the ignition on and I can hear the fuel pump priming also, plus I'm certain there's no break in the wiring itself due to checking it over and over. Oh and the immobiliser light goes solid for about 2 seconds after turning the ignition on then goes out so I'm guessing it's not to do with that.
Pretty much stuck for any ideas, would ideally like to get this on the road soon as my other project car's waiting to get started on (call me impatient :rasp any thoughts and ideas would be very much appreciated
