Turns out my harness was made in 2002, and i guess the rat did merk me..
turns out the crumpled wires in my earier thread was just my fuel pressure sensor

anyways i tried following timmyr's advice to inspect the coils/plugs/injectors/wiring

and i thought id just post this thread as an update for him, as pms do have a limit.. and its just easier for me to type.

DIY NOOBS FTW! thanks again timmyr

The black intake thing was actually easy as hell to get off cause the previous owner broke whatever it screwed to :|

first coil, a little piece of it fell off as i tried to take it out, i got the lower part of the coil off too, but i couldn't take the coil out! it just wouldn't come out!!

rat crap under the injector harness

injector harness so dry, that the sleeving/harness jacket is coming off..

opened it up a little for inspection

looks fine..

temporary taped it back up, going to research how to cover it up properly, with tape/rubber.

- not to mention whoever last installed the harnesss.. damn them for the zipties.. they cracked and cracked, as i had to cut through the, (the zipties) then again it is almost 9-10 years old since the harness was changed..

coil pack #2..

stupid thing broke off, and the solder points look red/brownish.. not good..

little bastard gashed me too.

injector #1 plug

injector #1

sure enough, timmyr was right, the injectors needed cleaning, and also #3 connector was loose, which was throwing the error #19 code..
but the problem is.. the damned injectors don't clip back in!!!

also i lost the nut to screw my battery negative clamp down..
and its 1 am.. so i called it a day.. :|

no diy ever goes well for me dammit! but im learning

thanks again timmyr.

btw what does this connector do? its by my battery tray..

note that my battery tray is all rusted, and so is the passenger side strut mount by the battery.. and many of my grounds seem to be on the rusted piece.. is that a bad ground?
