help car won't start, P0300, P0302, P1128
system too lean
multiple misfire
cyl 2 misfire
too cold to be digging through stuff and car is on the street, fuel filter was changed last year and i have 1+ with proper TT injectors. denso iridium IK24 plugs are few months old.
car started few hours ago but flashing CEL so i figure it's injector or coil but i have E coils.
i had a multiple cylinder misfire last summer with E coils that went away after few seconds and never found the cause.
so i ran some errands in another car and deal with this later but now its dead in the water
have to call dealer if my car had fuel pump warranty tomorrow
i hope the MAF didn't just randomly die

same code combo as I posted about down a couple posts
and mine won't start either, but I'm pretty sure thats b/c I left the ignition and radio on for like 45 minutes while trying to get vag-com to work with Vista. Hadn't driven the car in over a week, so I figure the battery was probably low on charge to begin with.

my red top is strong and cranks just fine at 0f, i hope it's not the pump or maf
i have no additional sensor codes
you can diagnose an O@ sensor by unplugging the front 02 and try to start again.
without the O2 plugged in it will run open loop preset maps. so if it still doesn't start the O2 is likely fine.
plus my car is only 62200 miles

Hmm. If it's not your coils with those P030x codes, it could be your cam
position sensor being off a bit, and causing misfiring/lack of start.
Check the basics: fuel, air, spark. Btw, even if your MAF is out, the car should start, it will just use default settings. I don't think your MAF is the problem, however.

update: injectors are spraying, that rules out fuel
changed coils to old working J coils, no changes, rules out spark.
no hoses are cracked or fell off, but of course it will take dismantling to fully check
disconnected o2, made no difference
disconnected maf, no difference
no start, doesn't even catch most of the time.

Have you had the battery tested, and the starter or alternator?
It's not enough to check the battery voltage, have it tested to make sure all cells function.
Crank/am positions sensors should still be checked.
