Hi guys, could really do with some pointers as I'm now burnt out.

So car started fine and took to my mates to do a gearbox swap as i lost 6the gear.

He fitted matching gearbox second hand and used the starter and reverse switch that were fitted to that. Through in a new non gen clutch kit.

Also did oil and filter and swapped both front springs as broken.

So did all that and now car turns over but won't start. I have p0404 fault code egr valve only?

Everything is connected.

First turn is delayed but then goes strong but still won't fire.

Any common problems?

Tia Sam.
