This is my very first post. I figure I needed to post my story and findings since I've been trolling this website for months now.
I have a 1998 C1500, V8, 5.0L, 305, Extended Cab, 91K miles with the original engine. In April, I drove this from NM to CA. I got about 22 miles to gallon. Truck in general is in fantastic shape. While pulling into my neighborhood and into my driveway one day, I noticed the engine misfiring. I looked around and noticed the smell of gasoline underneath the hood. I noticed there was a pool of gasoline on top of the fuel injector assembly, right next to where the 2 fuel lines enter. I pulled off the electronic connector that connects on top of the assembly and there is gas in there as well. That wasn't good.
One thing that I did notice was that my fuel pressure goes from 58 PSI down to 50 PSI and stays at 50 PSI with the fuel pressure rail check, engine on and it doesn't fall below 50 PSI for a while after shut off. I don't know if a fuel pump change would fix that since all I read on other forums is 60-66 PSI is standard for these trucks. But is 60-66 PSI for the older fuel injectors? OR the multiport injectors? OR does it matter if the truck seems to be functioning normally with 50 PSI?
I do know that eventually I will have to replace the fuel pump, because I think that the sender is going out or something. When I turn the key to 'on', the needle for the fuel gauge on the dash goes WAY past 'F', then goes back down to where the needle should be in about a second or so. But that's another story to be told in the future once I get the new injectors in there.
I know that this is was a long post. I feel like I should contribute to this awesome forum, since it looks like this website will be bookmarked on my laptop from here on out. I even replaced my entire A/C system, minus the evaporator and compressor by just reading some posts on here. Much more to learn. I appreciate it, everyone.
