Engine issues with 87 tbird
I got ahold of a 87 tbird 6cyl fuel injection that had be rear ended and sitting for a couple of hears with bad gas. They ran it on and off until it would not run anymore.
I drained the tank and added new gass and some additive to remove water slug and clean injectors. The engine will start but runs rough and will not idol. Plugs look clean. I replaced the fuel filter. Oddly enough, there was no pressure in the line. I can rev the engine to keep it running. Again, it s rough and dies after I let off the gas. Holding the gas down half way causes it to die. I can only rev it to keep it going.
What are my next steps. Replace fuel pump?
Also I did notice radiator overflow tank has brownish gunk in it. Almost like oil or steering fluid. Any ideas. Don't think it is a gasket. Oil looks good just thin.
