My truck sat in the drive way over 2 months this winter. But bfore I left I replaced the fuel filter and fuel pump relay and it seemed to start and run ok. When I got back from florida it would not start. I replaced the fuel pump this week. Fired right up. When I went to the cashrobbers station to get gas it started to missing pretty bad during excelleration. I can still feel it miss while cruising. Could it be one or more ignition coils? OR something related to the new fuel pump install.

 

It could be either or neither.

You need to scan the truck for pending codes and set codes..
