I know the engine deffinately run before i put it in as it used to be my car.

It turns over but wont fire up.

There is fuel going to the rail,got a spark at the plug.
Havent messed with the timming chains,i only change the pick up pipe didnt touch the oil pump.

Just dont understand why it wont fire up.Checked that all the wires are connected to there relevant plugs.

Could it be my wirring to the c101 plug?

Has any one got any ideas as to what else i can check or try to remedy this frustrating head ache?

i had this on mine turned out it was a bad earth from engine to chassis i also put earths on both engine arms hope this helps

have you checked that the fuel pipes are the correct way round? the silver one is the feed black return.

How daft do i feel

She`s alive!!!!!!!!!!

pleased to help, its a great feeling when an engine conversion starts up for the first time .

haha I have done this before and also a friend has done it !!!!

seems to be an easy mistake to make

It happens because people assume that the fuel pressure regulator controls the fuel pressure going into the fuel rail. It actually controls the pressure by regulating the flow from the rail.

That is 100% exactly what i thought when trying to work it out.With hindsight it makes sense that it works that way.
