Now Im trying to troubleshoot my MSD because my light blinks every 3 seconds at idle and its suppose to blink everytime it gets a signal. My first priority is to check the power current to see if it's at 12V. Next I was wondering if it's not getting a strong enough current then what could be wrong? also How do i check my coil packs and wires to make sure they are still good?

I ran a diagnostic tests on my '96. It showed one of the coils weren't working. Check your ground wire......I was having trouble with the ground wire.

it showed a misfire on all cylinders. It said ignition coil and/or input wire malfunction. Something to that effect. It also said it wasn't receiving a signal. I just changed the coils out it it's running fine now. My MSD is over at a friends' shop getting looked at because there was no blinking lights at all.

We ran a diagnostic today and all we came up with was a malfunction MAF and a 02 sensor mal. What I want ti do tommorow is get one of those volt meters and test the voltage going to the dis-4, then I need to learn how to use the meter to test ohms and resistance so I can chech the coil packs and wires. This is getting fustrating:(

If you ran the diagnostic and it didn't tell you about the coil packs.....it's probably still good. It'll say "coil ignition A (or) B malfuntion. Oh.....since your under the hood, check your plugs. Hang in there and keep me updated, just a small bump in the road. :D

These are brand new plugs, we just put them in last weekend. I will let you know how tommorow goes.

...when I did mine @3 yrs ago I had a similar problem and it was traced to a bad connection between the two harness, one green wire ahd a bad "crimp" on the connector, re-moved it & re-placed & prob gone...also make sure the two harness plugs are tight.

What did you use to trace the problem? I checked the wires and it all seems to be connected. I also checked the ground and made sure it was getting voltage. Yes I have tach adapters.

what I did...

...is called a "wiggle test" and just as the name implys...just looked at each wire, pulled on them, wiggle them untill I found one that broke under pressure.
