If you have a 93 model, you more than likely have the 1st gen ECU, which the capacitors are junk. You can check to see if they have done damage, by just pulling the ECU out, and open it up, check the motherboard for a black substance, that you KNOW shouldn't be there.
Well the ECU has been checked, it's throwing a code pointing at cam/crank sensor, also I just finished testing all the wires and they're all fine for both of those. Gonna' replace the sensor(s) and see if that works I suppose.
And don't you have to have a 1g ECU in a 1g car?? lol
What's your fuel pressure doing?
1993 3s were frankenstein cars lol.. they are mixed with 2g and 1g parts
The fuel pressure I'm assuming is normal, haven't checked it as I can feel the relay, hear the pump, and my injectors were just tested a few months ago and fuel delivery seemed to be fine.
Either way, as for now I need to know why it isn't sparking.
And yeah, I seem to pick whatever I can that'll make it a little more difficult or confusing. ha.
Thanks for the replies everyone.
yea, tell me about it...Quote:

Seems I had a post disappear. I saw you used a 91 SL ECU so I assumed you were a 91-92 car. Seeing how you are a 93 the crank sensor is mounted behind the crank pulley. Sorry for the confusion.
Actually I was going to ask you about that Corey, because I had gotten the notification email, but I couldn't see it... well, it's the first post.
I don't know how you did it but you jacked my thread, and posted that in 1969, seriously, go check it out. First post of the thread. LMAO
Awesome.
So I guess I'm just on a dumb streak and am asking before I look, my apologies to everyone, but I'm a computer tech. not a car mechanic, just not 100% confident I'm doin' stuff right. Anyways, timing jumped, figured I'd have to take it to a shop but I guess I'm just gonna' get all the rest of the tools I need and take my time and do it myself. After I fix the timing/cams, and that sensor (and replace the outer belt on the harmonic balancer) I'll post back with update if all my problems are fixed. I've been dumping money into this misfire/sputter/randomly running like crap... I'm guess my timing has been slightly off since I bought it and I've just been knocking it farther out, guessing from the distance off, and that my belt has all it's teeth. Sometimes I wish I didn't always learn things the hard way... lol
And whoever said I was gonna' break stuff, I take back my comment and admit you're right. I guess I shoulda' checked that long before, possibly could've avoided a few issues (or fixes that didn't fix).
Anyways thanks a lot for all the help, any hints/tips on the timing? Reading old posts on the old site, seems to be fairly straight-forward.
