Have you tried displaying your error codes? Post up any results.

Did you replace the low pressure fuel pump, or the high pressure pump or both? From you description, I would have almost put money on ignition coil failure being the problem. Did you replace it with a new OEM item or a used item?

I have done both high pressure and low pressure, also put ecu into diagnostic mode and came up with 12 (witch is no fault codes) also a brand new oem coil.

Pull a plug, crank it, does it spark?
Pull an injector, crank it, does it squirt?
IAC working? Throttle stop adjusted correctly?

That's air, fuel and spark.
Let us know.

And if those 3 are OK check the compression- especially after a rebuild.

I have pulled a spark plug getting spark, have pulled an injector and is spraying, replaced iac with one off a running car, checked compression. All is good there.

Then it must be sparking at the wrong time. Have you had the dizzy out? May be 180 deg out

I have put the dizzy on factory specs on tdc compression stroke.

Checked that the dizzy rotates with the motor?

Yes rotor is rotating clockwise. Ive tried mostly everything im just lost.
