ms3x on jeep 2000

[weeters]

I have wired everything up but i can't get any spark. I wired the stock coils up to coil A B C. might the logic outputs not be strong enough to trigger the coils?

Have you read the section in the Hardware Manual about ignition coils?

yes but how do i know if the stock coils are low or high?

[jsmcortina]

Compare to the examples in the manual. Check for factory wiring diagrams. Measure the coils with an ohm meter.

.6-.9ohm which should work. manual says less than 1k.

[jsmcortina]

0.6 ohms means it is a high-current coil. You need a coil driver such as the Quadspark or another external ignition module. Those coils cannot be directly connected to the MS3X outputs.

Ok this is where i'm at. I am using a ds61 ignitor to trigger the coils. they fired once and that was it. i am using coil a-c from the ms3x. the factory injectors are running off the ms2 board. i don't know any other information you might need. I am attaching tooth composit an sq file.

Do the coils fire when using the spark test mode?
