how to do a diagnostic

[lifesnotfair]

My car died on me last night. I called my sister's husband and he pulled me with a cable (illegal here, but didn't wanna pay tow truck). I did the diagnostic today, I have codes 42 and 43. I know 42 is because I removed speedocable.

So 43 is what made my car suddenly shut off last night.. or at least I think so... gonna check some stuff with the multimeter, but I'm no good at this stuff. =(

my car is also blinking 42 and 43.....but only when i start it, and turn it back off and then put the key to on again. It runs fine thou. im guessing 42 is cause my speedo is broken, but what exactly does 43 mean?

[suprra_girl]

code 43 is starter signal, no starter signal

I did read that, but what exactly does it mean? my starter works fine. is it perhaps because i removed the alarm and grounded the start wire? do i even need to fix that?

my car also died sometimes...i had a loose ground wire. couldnt figure it out for sh1t. just a little bit of info. haha.

I got what I think to be error code 11, however there isn't a code 11 in that manual. Wonder if someone could help me out with this one. Although my CDS (Possible standing for Computer Diagnostic System) fuse is blown.

I don't get a check engine light when driving, or when sitting with ignition set to "on".

momentary interruption of power supply to ecu

check all grounds, battery to chassis and grounds on the manifold as they may be broken or crappy connection

i was driving on the highway for about 5 or 6 mins (city driving 10 mins before highway) and the check engine light came on. after leaving the car parked for 2 hours, i started it up and it was off...untill iw as on the highway for, again, 5 mins. I got home, turned the engine off, took the keys out and restarted the engine, and it didnt come on..

tryed to figure out that E1 and T thing...i dont know what im doing though, i THINK i know what cable to play with..but i dont know which is T and which is E1....even if i do, will the code show up if the light doesnt come on until the highway?

sounds like code 52 which is knock sensor, check to make sure your plugs aren't broken and that (if turbo) both are plugged in (if na) that "the" knock sensor is plugged in

get a piece of wire and you should have to open the lid on the diagnostic box, inside the lid is a diagram of what each pin is, there you should find where te1 and e1 is

if ever you do a diagnostic and you have put the wire in but your check engine light stays lit and doesn't blink thats because the wire has not made firm connection in both of the terminals

call me stupid, but i cant find a thing that talks about the knock sensor, even online all i get is 1992 and newer...i dont know where the thing is..

(it couldnt have been my gas cap not fully tightened could it? i saw today that it hadnt been tighened all the way till it snapped. I know the newer cars have that problem connected to teh 'check engine' but im not sure if the older models do)
