Po370,p1690,po230 can you tell me for sure it has something to do with injecter pump and lift pump[:@]

 

Could you tell us what year this is? Assuming It's a 5.9 DSL? Never mind, I found your other post. You must have the later engine 1998.5+
I have seen an article about installing a lift pump pressure gauge that the driver can monitor all the time from the dash. If you see the pressure go low or out you can shut down before the injector pump takes a dive. Can't find that article right now.
