I have a 1999 3500 4x4,auto ,cant get it going !! Just got it, relocated lift pump with draw straw,worked great for 2 weeks,shut it off ,tried to start it

no go.

Problem seems to be lift pump not running. Checked wiring /extension to pump.

Sometimes pump will run for second when key turned on.

Bump starter,pump does not run.

Ran 12v from battery to pump,runs but is a bit noisy. Have a new one on way.

Checked fuses in dash panel,all ok.

Looked over fuses & links under hood , appear ok

Switched fuel heater/diesel relay with trailer relay( same type) ,no change.

Swapped fuel system relay with horn, no change !

I would really like to get to get this thing going !!

Any suggestions would be appreciated.

Check your codes... Did you set any when the lift pump failed? Hopefully you caught it in time.



Cycle your ignition switch 3 times (without bumping the starter) and leave it in the on position the 3rd time to check the codes. The codes will show up in the odometer window.



Do you have a fuel pressure gauge or a low fuel press led?



Did the pump you relocated have some sort of by-pass?

Cycled ignition 3 times ,left on 3rd time ,no code comes up. Tried this several times.

I had a check engine light when problem started.

I have a code reader ,tried it -- P1688 pd 01/01

Time for an injection pump too.

1999 does not show codes by cycling key like 2001 does.



The no start symptom and 1688 code read by your code reader is usually an indication of bad electronics inside VP44 injection pump and requires replacement of the VP44.
