Three times there has been a 1093 code set, the Auto Zone guy said it was a “I’m starving for fuel” code. I had filled with 100 gallons of Biodiesel in Georgia and afterward the attendant said it was made from chicken fat. Still good but had fatty deposits formed at 40 degrees F. So I transferred about 5 gallons of “chicken fat” to 25 gallons of petro diesel. That’s about 5 to 30 ratio or 1 to 6 which is … let me see… carry the one… 16% or B16.
At some point later I could feel a “miss” so I changed all three fuel filters, problem solved. Then last week the first 1093 code appeared, I had it cleared, it came back so I ran straight petro. The big tank in the bed quit pumping altogether, I changes that filter, problem still there (it’s in the 30s and 40s outside right now (NW WA State). In SoCal it seemed to flow so I eased a little into the main tank.. no problem. While in BC I mixed one half gallon of Howe’s cleaner in the big tank with the remaining 30 gallons of (by this time) B5 or B2. Now the little electric lift pump has everything flowing, the SES light extinguished on it’s own but I have a fuel leak in the valley that dribbles onto the ground. Not much, but still there’s a leak. The GM Goodwrench mech (my transfer case went south…again) said the injector pump is about to go.
I have almost 300,000 miles on the engine so perhaps it’s time for a pump. They are about $1,000 from GM. Would a rebuilt pump be worth it? Would there still be any residual sludge in the fuel system that needs purging and how would I clean it out?
It’s an ’02, with a ZF6, CA emissions and no mods.
I drive about 10 to 12,000 miles/mo and need something dependable.
By the way, 300K miles on the original brakes, front end parts and the spare’s never been out of the cradle. The General does a few things right
