Hi everyone! This is my first post here, so forgive me if this the wrong section.
I have a somewhat bizarre issue and thought I would see if anyone has any ideas. I have a 06' LS 4wd with the 4.2.
A few months back, I replaced the fuel pump as the sender unit went out, and after about a week with the new pump, the car began to not want to start until the second crank. With the pump being a Delphi, I doubted that it was the issue, but I decided to replace it with another unit anyways. Same issue. While I did the spark plugs at the same time as the fuel pump, I believe this is a fuel issue, but I don't know what else the issue could be at this point unless I just somehow managed to get two dud units in a row.
I should mention that after the car starts, it runs great. No CEL, either.
If anyone has any ideas, it is greatly appreciated!
Thanks!
