i checked for codes on my truck tonight and it came up with 230 and 577. what are they?

 

PO230 Fuel pump primary circuit malfunction
PO577 Cruise control circuit high imput

Do not what all this means but good luck.

 

does code P0230 mean my lift pump is ready to take a dirt nap?

my cruise dosn't work so code p0577 pobably has something to do with it.

what should i check to find out what is wrong?

 

P0230 Error - I would double check all wiring, fuses, and relay for the LP pump. It could be as simple as a dirt connection... But yes... It could be a sign that the LP is taking a dirt nap. Do you have a fuel pressure gauge???

P0577 Error - I'm not certain myself on this one. But Once again it sound like a wiring problem. Like the signal line is shorted to +5V line or something. I would gamble a guess at the clock spring. There was a lot of problems in the past about this but I would check everything out first...

 

no i don't have a fuel pressure guage on it so might put on a new pump this week to be safe. Does anyone have the Cummins part number for the better lift pumps, the school bus pumps?

I bought the extended warranty so i could just let the LP die and kill the injection pump too and get both pumps replaced for $200 (the cost of the deductible on my warranty)

 

Cummins Number 4090046 - Shown in pic below...

 

Mopar1973man - how much did that pump and fuel line setup cost and where did you get your lines from. i need to upgrade my fuel system to get ready for more power

 

Pump cost $46.90 for a Carter pump at Rocky Mountain Cummins, Boise ID

and...

The fuel lines... $129.95 at Vulcan performance - Vulcan big line kit...

 

thanks i will have to run over and pick up one of those pumps this week cause i can't afford to have it die on me
