This is about the Lift Pump and Injector Pump on my '03 CTD HO. I don't
have a FP gauge installed as yet and I have ~72 thousand miles so far.
Power isn't what it used to be, but I can still haul a 5th wheel up the
hill... just takes longer.
If the LP is shot, or going, the IP is soon to follow as far as I've read.
Two questions come up.
First, if the LP is shot, how long till the IP goes out? Depends on driving
habits? I drive <40 miles to work, mostly freeway, a couple of good grades,
same on the way home. I tow ~7500# once a month or so. Does the IP go out
within a few miles? days? weeks? unpredictable?
Second question is a bit more involved. If I take a dead CTD to the dealer
and they find the LP and IP dead, which is warranteed? Here is why I ask...
In the Warranty book, under Fed Emission Warranty - Heavy Duty Truck, it
states a Heavy Duty (HD) truck has a rating of 10,000lbs GVW and an M in the
4th position of the Truck ID number (VIN I assume?) or a 5, 6, 7 or W in the
8th position. Mine has neither. My Window Sticker (saved it) states that
this truck is a Heavy Duty truck as do the tailgate badging. What's up with
that? Is it a HD or not?
Under Fed Emission Warrantee, the "electronic fuel injection system" is
covered to 5 years/100,000 miles. What defines the system? Is it from fuel
cap to injector or from IP to injector?
What is covered under CA Emission Warranty if this truck was originally sold
in OR (CA sold no HO CTD's in '03) then purchased used in CA.
In the DC 7/100 Warranty, the IP and Injectors are covered, but it doesn't
seem to include the LP.
So, now a third question. If my CTD dies, and I tow it home and replace the
LP myself, then tow it to the dealer, will they cover the dead IP?
