Any ideas-lift runs ok on lpg. On gasoline spits and sputters
blows smoke from fuel. Plugs were changed-throttle body was full of black goo. Cleaned up. Replaced injectors-
scanned with hitatchi scanner-nothing as far as ignition.
Customer installed a new fuel pump sender unit in tank last summer-
thought maybe not good pressure-ran with a stand alone electric fuel pump (hi pressure) direct to bypass-no change-thinking possible ecm or wiring issue
