Ignition Control Module - 87 Samurai

On my way to Mom's for T-day last night, I nailed a large tumbleweed on the freeway. Shortly thereafter my 87 Samurai started intermittently losing power; it would decelerate and stall, then it'd run fine, then decel, etc. (even after I unhooked the tumbleweed from the grille). I finished the trip on the back of a tow truck. [img]images/graemlins/crybaby.gif[/img]

Mom's mechanic looked at it today and he thinks it's the ignition control module, but he can't get it to poop out at idle to pull the code. It seems he thinks the tumbleweed was just coincidental, but I'm wondering if it has anything to do with the fact that the small fan in front of the radiator wasn't turning when I limped the Sami down to the the shop this morning. Any thoughts? What's that little fan do? Is it supposed to turn all the time? What happens if it's blocked?

Is the ignition control module something I can find at a parts store? Or are we looking at dealership? I didn't find any information in a search of the forum.

Re: Ignition Control Module - 87 Samurai

I am a little confused. Both my 87s have mechanical fans behind the radiator so I am thinking the fan is electric and for maybe AC and no, will not run until the AC is on or it has a thermostat. What ignition module are you talking about? Is it the ECU under the glove box? Jim

in an '87 there are no controls outside the distributor except the coil and I have never heard of one of those going bad

sounds like a fuel problem to me

Re: Ignition Control Module - 87 Samurai

The chances of that being coincidental are about as good as lightening hitting you - on just your little finger while you are eating pickle flavored ice cream.

Best way is drive it, make it happen, as soon as it quits don't turn the key off, coast to a stop, pull the coil wire and crank it - look for spark. If spark, it's not the module for sure - fuel related.
It may take a few tries, but it's worth it.

Look around the distributor for sticks and rubble - loose cap, loose coil wire, loose harness etc, look at all electrical connections for damage - when the weed breaks up, little sticks get everywhere, pulling wiring around.
If electric fuel pump, check all the wires to it.
Check closely around the starter - where the main power is picked up.

Once you see it, it'll be obvious. I've seen tumbleweeds do strange, and laughable things.

Re: Ignition Control Module - 87 Samurai

First off, on an 87 you don't actually need the ECM to run. It will run a bit rich, but try unpluging the module
and see how it runs.

If it does the same, you have eliminated the ECM as a culprit.

What the others said as other possibilities. I'd think fuel or ignition. Possibly the coil or ignitor inside the dist.
Maybe the cap.

Coils go bad all the time on zuks and for some reason I can't figure, they go half bad, and will run intermitantly,
in a way that has nothing to do with heat, which is the only way I have seen coils be intermitant in the
past.

Re: Ignition Control Module - 87 Samurai

Sounds like your high tension lead from the distrib to the coil has come loose. With the engine cold, reseat (remove, reinstall) all the spark plug wires and distrib to coil wire. Make sure the wires to the coil are tight.

Re: Ignition Control Module - 87 Samurai

Hey, that's a lot of good information! [img]images/graemlins/laugh.gif[/img]

I forgot to mention in my original post that the guy says there's a) good fuel delivery to the carb, and b) the carb float is fine.

He said something about hooking it up to a diagnostic machine, and I just assumed that was the code-pulling procedure. Time to learn as much about my Suzuki as I do about my old VWs, I guess.

Does anyone know if there is a Suzuki dealer still extant within 100-mile radius of Banning, California? Gay Hood in Riverside has dropped them. I find no current listings for the Palm Springs or San Bernardino area.

I soooo kicking myself for not bringing it to Mom's so I could be noodling around with it today or tomorrow. Mom thinks we can get the guy to release it to me if we stop by his house (the virtues of small-town living). That may be an option by this afternoon. Meanwhile, I'm going to get me some repair manuals and start studying.

Re: Ignition Control Module - 87 Samurai

How'd you do dat?! I was all over the internet last night and couldn't find anybody!!! I even checked the Superpages for Victorville, and nada! All I found was a dealer in Riverside --Gay Hood -- who turned out to have dropped Suzuki.

I got a new coil from Napa and I've got a dizzy and an ECM coming from this place up by Sacramento, www.4subarusuzukikiaparts.com. (Replace 'em all for good measure.)

I also printed out some posts from you guys to put in the Haynes book I got today, to leave with the mechanic for the week.

I'll have to get a rent-a-car to get to work this week.

Thanks for all the input everybody!

Nikki
