Megane 225 no start issue

Evening all, for some reason I bought another meg 225 I really don't know why was more of an impulse buy.
Anyway the car was a none runner when I got apparently the fobs didn't work or start the car and it wouldn't crank. So I fitted a new battery to the car when. I got it and hey the fob unlocked and locked the car and the car cranked (did not start). Also noted that I had keyless entry which was unexpected.
Anyway so I done compression test all 4 perfect, checked fluids and again all good. I then removed the sparkies and replaced with new OEM ones, I also replaced the coil packs with brand new, car still didn't start so I thought let's check fuel to rail and yep loads of fuel. I bought a brand new OEM tdc, and brand new OEM injectors and guess what I still have the same issue.
The car cranks over coughs then dies anyone have any idea's? I am thinking it's spark related as the spark plugs are wet, I have removed coil pack 1 with spark plug and it arcs fine dueing cranking I'll try the other 3 tomorrow.
Do we have a wiring diagram for a 55plate 225?20160714_132542.webp 20160714_132459.webp 20160714_132420.webp 20160714_132333.webp 20160714_112831.webp 20160713_112305.webp 20160713_092924.webp
 
Looks like its got a few faults stored. You need to click on injection and you can get onto another screen to see what fault codes are stored. Its been a while since i have used it
 
Yeah I need to learn how to use it properly, being so old the laptop battery didn't last long ordered a new battery for it so at least it will last an hour or so I hope. I'll do some YouTube searching.

Kinda got it running this afternoon, played with a few bit's it needed alot of pumping pedal to keep it running though,

Constant pumping pedal to keep it running or it would die, the noises you can hear are the exhaust and the BOV.

1st start



2nd start and left to run (well kinda stays at temp noise)



3rd start




Going to look at fuel pump next
 
Oh, I missed you'd done injectors my bad.

Did you switch out the fuel pump?

What dump valve setup is it running? In the first video when it suddenly died with the jolt, were you revving it? What happened?

No fuel pump is next to do I have a brand new one but lack of tools to get the ring of stopped me doing it as I didn't want to break the ring.


It's got a Forge D/V, it died as I stopped revving at that point. I plan on changing the D/V as I have a forge intercooler kit and pipes to fit to the car yet
 
Ok new fuel pump fitted car did take a while to start needed the old pump the peddle. I have risked driving the car and I have covered 7miles I have noticed when accelerating alot of black smoke as if way to much fuel. The car seems to start perfect each an every time now when used during the day but if left over night it does not want to start at all
