Recently replaced long block of V6 motor using original manifold and electronics.

Will start--runs rough and fuel comes directly out exhaust.

Need to know what all should be checked that could cause this.

Hi Kevin_Aune,

Thank you for the donation.

Excessive fuel are mostly cause by bad injectors that are stuck in the open position.

You need to remove the injectors to test.
