Mopar Fuel Injection Kit ????

[SitNonBlocks]

I have someone building me a new motor and they have taken the Fuel Inj Kit off my old motor and put it all back together. They are telling me that at cold start it is dumping to much fuel in the cylinder and washing all the oil ect.. They cannot not tell what if the injectors have been changed from the OG ones that came with the Kit. I did not install the Kit so I do not know either. Has anyone heard of this issue. Does anyone have any idea what injector should be in it.

Check the vacuum going to the map sensor. Make sure you are pulling constant vacuum and not just vacuum at WOT.

Check your fuel pressure and/or regulator.

Check your fuel pressure and/or regulator.

factory spec for regulator is 40psi. which is a little on the lean side.

Stock injectors for that kit should be 19lb ones. If you need some let me know. Fuel rail should be regulated off at 39-40 psi. I would check the fuel pressure at the rail and then move from there.

Let me know if I can help.
