mother ******...well after being off for over 24 hours, the light came back on same thing. I dont know what the **** is wrong. i changed the fuel filter and put in some additives to get it to go off, god knows the filter isnt bad... I checked for leaks around my intake manifold and that is all good. this **** is just stressing me out. Anymore ideas?

I think maybe i had ALOT of water in my gas, and the new fuel filter made it run good for a little bit, now the new filter is saturated with water as well? so the light is back on?

what do yall think?

Do you have access to someone with tuning software? If you can, log the sensors and make sure everything is within range.

Mine did the same thing when I ran E-85 fuel in it. It popped the code so I babied it for a couple days then filled up again with 93 reset codes and never again..... good luck man

A Local auto parts store should have a code reader that they will use to check the codes for you. Any basic code reader should be able to clear the codes. If all else fails try disconecting the battery for a minute or two.

this **** is so annoying..i hate having my light on.

could i have a bad o2 sensor, maf sensor, or fuel pump and have it not spit a code?

if i had water in my gas, will that water ruin a fuel filter? I changed filters and it went off, but im worried i still had water in my tank and it ruined my new filter too.

Fuel pump Yes... the others usually generate a code for there specific fault. The pump how ever usually has no warning. the only indication is usually a faulty sending unit.... but I have seen them last as long as 6 mo to a year after that starts poping up. I forgot did you check the fuel pressure under idle and again at reving it up???

Thats interesting on the sending unit. Mine's been out for at least 3 years and the pump is still going strong 150k miles..

LOL... ya I think most of the ones I have replaced they were having trouble for around a year possibly longer. I don't keep specific track of each one. My pump started going at 100K my sending unit started acting up about 6 mo. or so before that. I do alot of short trip driving though... Buddies died at around 120k . I know I did one in a truck recently that went out around 186K and suburban or tahoe that was some were between 200-220k but he did alot of highway driving...
