Take a paper clip, hold one end of it against the wire. Flick the other end against something metal. If it sparks when it makes contact, you have 12v. If it makes contact too long, it'll weld itself and you'll blow a fuse, thus the flicking.

LOL!! But really, I'd be checking coil voltage before pulling the front of the motor apart again. Takes two seconds....

Front of the motor is takin apart. lol I can have the crank sensor taken off in 5 mins. I only have a crank pulley and one accesory belt in the way. there is no cover. In wanted to get it running w/o the covers so i could check for water pump leaks. If i dont have 12v at the coil, how do i fix that? what would that indicate?

Well after putting a new CPS and regapping it to .030 I still ahd no fire. So i swapped the coil pack and it fired right back up. Problem is is that the coil pack i swapped it with looks like this.

Think i can get away with using it?

Im going to drive on it for a couple days to see if it lasts untill my new coil gets here in the mail, im going to wrap it up in electric tape and di-electric grease. Hopefully it holds

Also, you mentioned you used dielectric on the dis. If im not mistaken you are supposed to use heat sink. It's available at radio shack. I think dielectric can cause the dis to overheat.

Well i got the car running but as soon as i puled out of the drive way it died. No spark again. So i figured i would replace the coil pack with a new one since the coil pack was cracked (see pic above)... Put in a brand new coil pack and still no spark. Turns out i popped the DIS. (this is my third one). Took it to get tested at autozone and it failed with flying colors (all 6 red light and no green ones). So whats making my DIS's pop? Can they pop from a loose ground or being grounded poorly or somewhere they are not supposed to? Or is it possible that coil pack being craked like that ark ersumshit and make the DIS pop? Or do you thing its just a cowinkdink and i recived two bad,or poor DIS's?

Im out of thanks but thankyou for clarifying everything for me. Im sure this is the problem.

There you go. I did it for you.

You did good bro my first rebuild I f'ed up so bad that I junked it in the end. Yours was running so you did a thousand times better than me! I have been watching your updates on fb wile you have been doing it. I hope it is up and running soon.
Don't get discouraged!

If you're having a ton of electrical problems like you are, it's time to tell your friend to bring your multimeter back. Just sayin'.

Also, you need to use thermal paste, not dielectric grease. If you are using grease that explains the DIS failures.

That may be quite possibly the stupidest advice I've ever heard.

Perhaps. But it's a turn signal light away from what I do when my multimeter is "with a friend".

Mr. A
Zach is a teenager. He lives on his own, pays his own bills and has yet to graduate HS (I think..maybe he graduated last year). Since joining this forum and having the crap kicked out of him verbally, he's stuck with it. Now he's got a complete SHO engine swap under his belt.

One more thing, you called him a ******* *****. That makes you look like one of the people we try to keep away from this forum.

Zach, you need to go to the computer store and buy some heat sink paste and put on the back of the dis - dielectric grease does not do what you need - you are overheating the dis by not having the right heat sink paste for thermal conductivity.

ps - what language are you using in the quoted post?

If it makes any difference there was white heat sink paste on the DIS still, There was just di-electric grease over that. lol. I should have a new DIS around wendsday so ill give it another try. Just hard to understand a DIS can overheat in the 1 min it was running.
