History of bad inj pump
Bought Truck with 43K miles, Very good condition,
with inj pump replaced at 26K miles.
The first time I drove it I noticed a miss/
at about 1600 rpm when converter locked up
ran smooth under hard acceleration or above 1700rpm
45k mile, would not start, or start and quit,
Remote mount FSD fixed problem( I reconnected BAD pump FSD, it would fail after a few weeks and
cooler temp.
All's well with remote FSD for a few mounths,
Stall, restart ok, happened several times.
Dealer said it had one short inj pulse code..
Probably FSD,
Install New FSD on remote mount, alls well for a year...
Stall/ restart several times, hook up bad
pump FSD , drive to Standyne, read codes, none...
BAD FSD ?, By new one , alls well for 2 mounths.
Go on long trip, 104 deg, stalls several times.
install old FSD same thing,
Next Day after 20 minutes stalls several times than ok all day.....
Call Gomer ( Probably Pump )
Start to Drive from Neb to Missoula,
Starts to stall several times when ever eng
restarted , Now Windshield wipers quite.
Stop for new Control unit ( Serv Bul)
Ask Chev to replace pump, No codes.
Drive truck No stall., No Pump.....
Start driving to Missula, Stalls 4 hours latter..after restarting at rest area...
Replace PUMP
Thanks Gomer and Rocky mountain Diesel!!!!!!!!
12K Miles Latter, Runs Great AND no
miss at 1600rpm!!!!!!!
5k Miles on remote FSD that I thought was Bad,
I am now in the process of testing all my suspect FSD's
Bottom Line.......1. Intermittent Stalls may not
be FSD.
2. Screw GM Service...
