Acts like it wants to start, will turn over, will start, then die in like 4 seconds, used starting fluid earlier and it started for about a minute. ONLY THING I HAVE DONE is topped off fluids, just bought this truck today, Please help..

Just filled it up :(

sounds like it has spark,now you need to have the fuel pressure checked.

I'm replacing the whole fuel pump, just replaced fuses, and put more gas in it lol.

if you check the fuel pressure first,you may not need a fuel pump?
