JerryB Posted December 6, 2009 Share Posted December 6, 2009 Gentlemen once again I ask for your valuable experience. My 2004 CX with 460 has a dead miss on #4 cylinder and the lightning bolt trouble light gives me a n 8-4 code. Do I need to take my truck to a diagnosis computer or just swap the EUP and then go get the new pump calibrated?

Mackpro Posted December 7, 2009 Share Posted December 7, 2009 There are 3 different EUP pumps. A different on for each type of engine, ETECH, CCRS/AI ETECH and AC ETECH. You have the the AC version. Hope they have them in stock. The EUP for the AI ETECH is on backorder, 1,5032 are on back order and we have a truck with 2 down and wont get one till after new years. Truck still runs but has codes and a rough idle, going down the road , its OK.

mackcl96 Posted December 9, 2009 Share Posted December 9, 2009 I think if it dosent have a "red" motor in it MACK/VOLVO doesn't care if you get parts or not.Me as a Mack parts customer, seem to have to deal with this almost every time you go to get parts they are backorderd or discontinued or superseded to a part that wont work.But we have parts for that new truck outside sitting on the lot.I know they are losing many loyal Mack customers for years over volvo's ignorance Quote Thanks for hearing me out.You can have the soap box now---------JIM Link to comment https://www.bigmacktrucks.com/topic/11706-code-8-4/#findComment-44834 Share on other sites More sharing options...
