I just bought a msd digital sci from summit, and I installed it in my swapped ek hatch, and now my car won't start. I hooked it up the same way I read it in the instruction manual,from various searches I looked up here on h-tech,I also looked @ the how to on c-speedracing.com. Everything is hooked up correctly. I checked,double checked, and triple checked and the car still wont start. It just cranks and won't turn over. DO you guys think I need the tach adapter from msd.What do you guys think can be the problem.PLEASE HELP ME OUT. my swap is a b18c1 in a 1997 cx hatchbatch

 

are you running the internal or external coil?

helloooooooooooooo!!!! anybody out there.

 

I would check to make sure you hooked the coil up correctly. Are you using the 12V and ground on the battery for the MSD box?

check for spark. if you have spark throught your wires then your plugs are wrong. i had that problem. you cant run platinum plugs with msd. only <U>copper core plugs</U>

 

I am running platinum plugs. i'll change them and try again. Also would the plug wires have something to do with the car not starting.Msd says you have to use heli-core wires.

 

do you guys think I also need the tach adapter, or is it not needed.

 

tach adapter is not needed...

check to see if you are getting spark. unplug one of the spark plug wires from the spark plug and stick a screwdriver in it. lay it over something metal in the engine bay, but not touching it, and have someone crank over the motor. you should see the spark jumping from the screwdriver to the metal.

if you can see the spark jumping then your msd is installed right. problem lays elsewhere.

did that and there is spark,could be a problem with the msd, because i put it back stock and the car started right up.

 

Did you cut the loops on the box? I know allot of people forget about that on the other box's but I'm not sure if the SCI box has them.

yep. the units usually come from the factory for 8 cylinders. Cut the first loop for a 6 cylinder and cut both loops for a 4 cylinder. Read the directions......

msd says for honda applications u don't need to cut the loop. I'll give it a try anyways.

the digital sci only comes with one loop. msd says they come set for 4 cylinders.

 

Then I don't see what the problem is. Your sure it has power? No blown fuses?

Read through the instructions again. Something obviously isn't hooked up right.
