Fueling Problem
Well last Tuesday 24-apr-2018 my check engine light came
on. AZ reads it as a P1451. As you can tell from my first post
I suspected it was something "Electrical" due to the suddenness
that the problem came on. "97rangerstepside" suggested the
EVAP system to me at that time. Also at that time it got COLD
here in the CLE and I didn't mess with it at all. Spent the Winter
of 17/18 "Drizzling" fuel into him at about 1 gal per minute
just to keep the pump from clicking off.
On the good side, it seems like an easy fix.
On the bad side, one has to wonder why it took the
Ranger ECU 6 months to throw a code. I noticed my mileage
went down the tubes, (I drive 300 mi a week for work) but
after the CEL came on I did 4 days on just less than 1/2 a tank.
Did the ECU just give up on it? AZ calls out Purge
Valve. Probably won't get to this for a while but will report
back whenever I do, I'm kind of a stickler for that. Endless
reports of problems, problems, problems never followed up
by Solutions, solutions, solutions...
Right now my "Take Away" from this is if your
3.0 mileage sux, check or just replace the Purge Valve. AZ
wants about $60 for it. I haven't checked AA or the Rock yet
but will.
Good Luck
