Vr6 help please

[Joemoy29]

Ok s here is the deal. Had a vr6 **** the bed so I purchased one from a kid who had cams put in did rebuilt head, decked the head .30 and mk4 head gasket. The engine has not been ran since the build. Put into a existing mk2. The engine has been sitting for a while all opennings were covered for storage
The issues are as follows
1) I have to push gas all the way to the floor to get it to start. When it starts I won't stay running. The engine won't keep constant rpm. When I have it floored it fluctuates sporadically
2) there seams to be alot of lifter noise
3) I took the gas line off the rail. I get no fuel on key on just crank not sure if this normal

I know everyone is going to say the timing is not right. Let's assume that it was done by a professional and it's correct

I changed the relay for the fuel pump, checked ecu power, changed fuel pressure regulator. Plugs dont seam that bad.
Thanks for any input

check the speed sensor and try to adapt the trottle body

lifter noise is common on a vr6

check the relay

Can I adapt the throttle body on a car with no obd2 port?

during one of my engine swaps into the mk4 I did the timing chains and the timing had jumped a tooth or 2 without me noticing. I couldn't get it to start without giving it gas then when it did it ran like ****. I would suggest not assuming the timing is correct and go check it. the fuel thing is normal.

Whatever happened with this is it fixed or still not running?

Could be a vacuum leak that keeps killing the engine
