Truck sat 1+ year - rough and won't idle
2002 3.0 MFI 5spd 45k miles , It was running great took it on a 1500 mile trip then took it to the store a few times then it sat for 3-4 months.
After this I went to start it and the battery was dead (duh) charged it but it did not want to start, seemed like it wasn't getting fuel.
The fuel pump was dead. fast forward a year and I have taken the bed off replaced the fuel pump and filter flushed the lines replaced the spark plugs and oil and filters also. Checked the spark wires for resistance and they are within spec. Also they are matched to the correct plugs too.
Took me a bit but I got her to start up but she is not happy.
There is a knocking sound that seems to come from the transmission area. Louder under the truck near the hole in the transmission casing.
Also she doesn't like to idle and throttle response is bad.
She wasn't throwing up a check engine light for me the first 2-3 times i started her up, now she is so I'm gona see if one of the auto stores will lend me the OBD tool.
What are some ideas?
I'm betting the code is gona be a misfire and maybe a lean code.
