Hi Welcome to Just Answer! Which fuel pump did they replace? There are two on your truck one is the low pressure or lift pump the other is the injection pump.

Customer: replied 1 year ago.
The pump mounted on the block was replaced, along with the fuel filter.
Expert:  b5demon replied 1 year ago.

ok did they say if it was the injection pump or the lift pump both are on the block

Customer: replied 1 year ago.
I believe it was the lift pump. The garage opted to replace the block mounted pump versus installing the pump in the tank.
Expert:  b5demon replied 1 year ago.

ok usually we recommend switching it to the in tank pump because of the issue we have had with the block mounted lift pumps. but your issue sounds more like an injection pump issue. We have seen a lot of issues with them acting like that and it usually happens after the lift pump fails too because the injection pump also uses the diesel fuel for lubrication so when the lift pump fails it causes damage to the injection pump due to the lack of diesel fuel for lubrication.

Customer: replied 1 year ago.
I assume that you are recommending that the injector pump be replaced. Is that so?
Expert:  b5demon replied 1 year ago.

yes they should double check the new lift pump but you will most likely need a new injection pump it happens pretty often

Customer: replied 1 year ago.
OK, Thank you or your help. I wish you a Happy New Year!! Best from Dan
