Ok I have a Samurai with a 1.6 8v, originally out of a Prizim. They are all basically the same engine. My motor is VERY build and I am running a cam with a 106* centerline and a Weber 36 DCNF carb. I hooked up my MSD 6AL like it supposed to be and the violet wire going to the positive (99%sure) wire coming out from the dist., and the green to the negative wire coming out from the dist.

Now I cant get it to start. It stumble a sec but never really catches.

Orange is on coil+
Black is on coil-
heavy red=batt +
heavy black=batt-

Now there was a blue wire on the positive side of the coil when I started, I took it off and have tried to figure out what it is, no luck. Does not seem like it provides any power.

I took the plug cap off of the coil and turned it over and heard sparks, but I still think something just aint right. I have the BLUE MSD wires and stock plugs.

oh and I even hooked up the light red wire directly to the batt, so thats not a problem.

oh and I cut the wires needed on the side under the cap and the tach line is not hooked up.

Try attaching that blue wire that was originally to the coil POS to the small red wire cluster of the MSD and see if that doesn't work.

In other words ALL the wires originally attached to the POS side of the coil should come off the coil and wire to the small red wire of the MSD.

tried that, no luck. :scared:

I have a large event this weekend and I would like to have the MSD working. Been hearing allot of good about. it.

oh and all the stock stuff is still in the dist. do I need to remove something?

What year vehicle?

86, but the engine is a 1.8 8v carb, from a 91 GEO Prizim. The Suzuki and Geo 1.6 8v are the same motor. Fuel pump is electric, and on a separate switch.

Oh and it is BUILT.

Follow the wiring diagram found on the bottom of page 10 WIING AN MSD TO A POINTS/POINTS AMPLIFIED SYSTEM.

Start from scratch, get the car running in a stock condition, then wire the MSD in according to the diagram mentioned above.

If fuel injected, you will need a tach/fuel adapter PN 8910EIS.

kewl it works.

tach is no workie, but I need an adapter. 8920 I think? I have a carb.

Also I need to find my other rev. pills. all I could find was my 6k. I need at lest 8k.

Do you have anything to support 12k rpms?




EDIT: Is it bad to be hitting the rev. limiter all the time on a 4 banger?

and b4 I forget, I had originally wired it like page 11 top diagram.

We do have a 12K chip available, this is part# ASY12472.

What distributor is being used on this?
Did the vehicle/engine originally have fuel injection and you converted to carb?
With this sort of engine swap there are quite a few variables involved.

OEM dist. and it was originally a carb. engine. It does not run a mechanical fuel pump, it uses an independent electric fuel pump and a regulator with a bypass to send any extra fuel above 4psi back to the tank.

It seems to be running fine now, the engine is built for 12k RPM's but I dont usually see that while rock climbing or mub bogging.

The applications I looked up show the '91 year model engines had fuel injection, with cam and crank sensors in the distributor.

I'm trying to figure out how you wired in the MSD unit to the distributor. How did you connect the MSD to the system?

your looking up the 1.6 16V this is the 1.6 8v. Its the same engine as the Suzuki Sidekick 1.6 8v carb, and the Tracker 1.6 8v. :001_cool:

It must not be an American model. The '91 and later models for Sidekick and Tracker have TBI and the coil is fired by an igniter none with a blue wire to the coil either.

None-the-less if its running there should be no problem. Is the tach working as well?

Polie

its American. lol

and yes its working.

want me to find the info?

look up the Samurai 1.3 8v. The dist. are the same, and no the tach is not working. It does not even register, flutter, or do anything. I just shift when I hit the rev. limiter set at a low 6k. I may put the 8k and just shift when it 'sounds' right until I can get that worked out.

If I where to get an aftermarket tach do I just plug it right into the MSD box?

Polie

dont forget its running a carb. not FI.

I was able to find the 86 Samurai with an electronically controlled carb. I've come across this before on this one. There is a filter in-line on the lead that connects the tach and ECM to the distributor and coil- terminal. You will need to bypass this and install a 8910 Tach Adapter for everything to work properly. One person I worked with on this had the same problem as you, the engine would run but the tach would not work. When the 8910 was installed, nothing worked until the filter was removed. Removing the filter and installing the 8910 allowed the engine to run AND keep the stock tach working.

Polie

so after the adapter is installed and the filter bypassed I keep the MSD installed the same like on page 10?

I will go ahead and get the adapter, but the carb is no longer electronically controlled. It is a custom mounted Weber 36 DCNF.

ok I hev the rev. limiter @ 6K and it shut down. I cant get it to restart; I think there is not spark coming from the OEM coil.

Perform the "Checking For Spark" test to test the box and coil. We have this outlined here:

yup did everything, traced it back to no power from the OEM coil wire (my 12v switchable supply), it was a blown 15A fuse. So from now on when I hit the rev. limiter I am going to blow a fuse? lol Looks like I may need to upgrade that wiring and install a 20A or 30A fuse.

The MSD box does not really draw much from that lead, it only needs it to turn the circuits "ON" in the box. There may be another device connected to that circuit.

k. thanks. I will try and track it down.

Sounds good, please let me know what you find.
