I've just recently had this issue start up with my truck where it will start, but only for about a second or two before it dies.

It was running fine with no issues the day before and the next morning when i went to start it had this problem. I replaced the fuel filter, but the problem persists. I checked the relay for the fuel pump and it's fine.

My next assumption is the fuel pump itself is bad. I wanted to check first that there isn't something I might be missing or overlooking before I commit to dropping my gas tank.

Thank you in advance and any advice is appreciated.

Sounds like passlock but I'm unsure what years started that...? Mine does this from time to time but the security light in the cluster will blink when it is acting up.
