The inertia switch is in the trunk on the driver side, it's got a little red button that should be pressed in. If it's not, push it back in. The car will not run with it tripped.
for the 319 and 195, are you sure you didnt mix those two up and they're actually different codes? The computer should read everything off at once, not wait 6 seconds to throw more codes. It usually waits 6 seconds to throw the 15 or 111, which is test failure, or test pass.
Well, the car does run, only after 20 minutes or so the MIL comes on and stays on. No noticeable loss in performance, no sputter, no nothing.
Anyhow, checked the inertia switch, red button was pushed in, so maybe it's a short there or someting, dunno, gotta bust out the multimeter and go to town on the wiring back there.
As far as the other codes go, it never gave me a 15 or a 111. It started off right from the start with the 21 24 ... series of codes. After that it paused for about 6 seconds, flashed a 1, waited another 6, and started flashing the rest. All my reference material suggests that the first batch of codes is 2 digit codes straight from the EEC as it's doing it's test, then it does the 6 second pause, flash, 6 second pause thing to indicate it'll now be dumping 3 digit codes from continuous memory.
Anyhow, looked at my notes and instead of a 319/195 it could also have been:
31 91 95
Because that sequence repeats twice. It does look like the fuel pump might be busy crapping out, since the 95's stored in CM as well.
31 and 91 respectively boil down to: "Canister or EGR valve control system or EVP circuit below minimum voltage", and "EGO sensor problem due to fuel pressure or injectors out of balance"
(Sorry by the way I'm most likely asking silly questions but english isn't my native language, and I still have some serious problems wrapping my head around any auto-mechanic stuff in English
Judging from the above 2, I'd venture a guess that my fuel pump is getting bad, because it fails on a test, and there's other issues that might be due to fuel pressure. Correct? Or am I totally on the wrong track?
Leaves me with a few questions still:
1) That Canister/EGR valve thing? Is it saying the EGR valve isn't doing what it should?
2) EGO sensor, is that the same as an O2 sensor? And if so, where do I find these puppies (I know they're in the exhaust somewhere).
3) The fuel pump. Can I take just any fuel pump out of a car at the junkyard? And um, (I feel silly asking), where does one find the fuel pump? Is it in the gas tank itself? Or outside of it?
Anyhow, thanks Thomas
