I know this sounds crazy but I don't know how you posted that so I don't even know how to put a post out there for people to even see what I'm trying to ask but I could use some help but hey I appreciate it if you have the time I appreciate your timeWell, I suppose this is as good a place to place an introduction as any.
To start off with, it feels good to be back on a forum, I haven't been on one since I had an LS1 powered F-Body.
Alright, so I just purchased this truck as a fixer to daily driver project. They just don't make them like they used to.
It has the 5.7/350 motor, not sure of the transmission (one problem at a time)
Current big issue is the hard starting, rough idling.
I've done some digging and ordered the MPFI "conversion" just from everything I've seen this HAS to be the root cause of it all.
I averaged 15mpg for 300 miles driving from Brownsville Tx, to Houston Tx, It idles rough, doesn't start right away (one start, rough idle, dies) then fires right up and idles rough, has NO power under acceleration, etc etc etc. All of these seem to align with a failing/failed CSFI.
I have changed the fuel filter and I'm getting ~55psi at the Schrader valve underhood with an almost immediate drop in pressure once the truck shuts off.
So, I plan on replacing that this weekend.
While I'm in there what might be some other things I should look at/into?
I plan on pulling/cleaning all or most sensors, checking the distributor cap/rotor, plugs seemed fine like a motor that's fuel starved (running lean), air filter needs changed.
