1996 f150 issues
Hi all. in the past you would mainly find me in the dent side section, but lately I have been messing with a 96 and thought I would turn to some old friends on this site for some advice. I bought my 16 year old a 96 f150 with the 302 and e4od. 120,000 on the dial. I swore I would never have one with a 302, but I had a weak moment and now I am paying for it. Check engine light keeps coming on, and I have a very old code scanner which keeps telling me that left bank is running to lean and the right bank is running too lean. Like I said, the scanner is early technology, but my thought is to start at 02 sensors.
The other problem he keeps having is in the shift linkage / indicator. The other day it would start in park, so I moved the lever to N, and it started. Once running and warm, I shut it off in park and it started again. We live in the frozen wasteland and he is a 16 year old kid, so before I jumped to any conclusions, we thawed it out in the shop to eliminate any ice or moisture. Fast forward to today and it happened again. Is this a common problem and maybe as simple as just an adjustment of the shift cable? if it can be adjusted it wasn't real obvious from the transmission side. The other thing to note is the indicator has gotten really sloppy, mainly between N and OD. maybe a related issue maybe not?
I appreciate any feed back, and thanks.

Your shifter issue is usually the shift tube and bushings. I had to redo mine in my 96 Bronco.

Awesome, exactly why I love this site. Here are some more facts:
Rear tank currently unusable as the pump quit shortly after I got it, therefore we are running off the front tank all the time. I changed the fuel filter almost immediately because I thought it seemed a little hard starting. Starts pretty good and seems to idle just fine. He does complain about fuel economy, but I just chocked that up to a 16 year old with no experience with a 390 holley 4 barrel. Ill search for the right way to check fuel pressure, and post results.
Thank you.

An Update, fuel pressure appears to be 24-26 psi with key on and engine not running. It stays at 24-26 with the engine running, and doesn't change at all when the vacuum line is disconnected from the fuel pressure regulator. when you rev the engine, it dips below 20. Does this point towards the fuel pressure regulator?

OK guys, I installed a new fuel tank and pump in the rear as I knew for sure that one was bad. Retesting the fuel pressure now it is at 30 psi on the rear tank, when I pull the vacuum line off the fuel pressure regulator, it jumps to 40. Subsequently, when I switch to the front tank, it drops back down to 24, which probably indicates a weak pump in that tank too, as Skuzzy eluded to. For the heck of it, I put on a new fuel filter and it didn't change at at all, so that rules that out. So what do I look at next? the fuel pressure should be higher then 30, correct? Also, I have check for vacuum leaks and cant find any.
Thanks in advance.
