Suzuki 1.6 Engine trouble, Help

I have a 1991 Sidekick with a 1.6 8V engine. The engine started dying out randomly about a week ago. It would be running fine and then just quit. Leave it for an hour or two and it would start just fine, then it could be driven for 10 miniutes some times, and sometimes an hour before it would act up again. I suspected the fuel pump and have changed that but it is still doing the same thing. So I'm assuming its an ignition issue. Does anyone have any ideas? Is there a common problem with this engine?
Any help would be appreciated.
Thanks

There is no common problem that I am aware of, but I would take a wild guess and bet the computer is screwed up.

Wow, that is a tough one!

I'm guessing loose connection from ignition-coil-distributor-spark plugs...

Either that, or a vacume line has a leak in it...

Ignition-Coil-Distributor-spark plugs...
It dies on you, not misses... So not the connection from Dist. to plugs.

Sence it WILL start up after time alone, it shouldn't be the ignition.

Coil to distributor...

Check the wires that come from the ignition to the coil. (side of the coil) and also check your coil output wire for corrosion/disconnection, ect.

If that doesn't fix it, check the wire on the side of the distributor...


BTW, if you can move ANY wire, apart from the coil to Dist., then that IS the problem, and needs to be tightened.

I know its not the fuel pump, I have changed that already to no avail. It died about 4 blocks from home yesterday, went to get it about 10 hours later, and it still would not start. Towed it home, tried it again and it started right up. I have tried wiggling all of the wires around the coil, distributor ect while it is running and there is nothing obvious. If I leave it parked and ideling sometimes it will only run for 5 min, sometimes it won't stall out again. This thing is driving me crazy.

I'm sorry I couldn't be more help, I am used to 327's and 350's... not computerized crap... I do know that you need 3 basics to make an engine run... Gas, Spark, and air... soooo... wait...

I just thought of something...

Check your choke.

I know you changed the fuel pump but.... when its not starting is the fuel pump running ? when you turn the key on it should run for a few seconds then stop sorry if you've already been thru/over this
try to check for spark while it wont start also
Id get a service book & test out dist /coil components if theres no spark
if all that checks out then Id have to look at the ecm I saw a guy on another board who fixes them reasonably

Oh! that is right! the 1.6's have electric fuel pumps... not the lever-pump... I would also say a short in the fuel pump...

Bass Man is right, you have to isolate the problem. Fuel, spark or air. If you don't have spark, and you have an ignition module, or something similiar, these cause problems when hot/warm. Also, if a fuel problem is suspected, put a fuel pressure gauge on it to verify the specs. Good Luck. Dave

Almost the same problem happens to me but my engine don't die, it just starts to stall if I start accelerating. The problem goes away soon as I turn the igntion key to off for a couple off seconds and turn on again and then works normally.

sounds like the same problem on my 90 samurai

mine is definitely ignition though I am not getting spark from coil to dist. I do have 12v to the coil and to the igniter. I don' t know if its an igniter malfunction or the computer. Let us know if you figure yours out. The igniter is $300? and computer is $200 to get rebuilt.

I mostly play with toyotas, however if the truck has a Fuel pressure regulator for the fuel rail it could be going out... On the 22re's the FPR is modulated by engine vaccume (has a diaphram in it) the seals in the diaphram can go out and/or the seals in the fuel end can go out...

sounds like a fuel problem to me, Also did you change the fuel filter?

Secondly get a Fuel pressure tester unplug the in side of the fuel rail and hook up the fuel pressure tester see what the fuel pump does when in the on position (and yes I read that you changed it, but i have gotten bad parts that were "new" quite often)

Also grab a 40k volt tester and hook it up to see if you are getting spark during cranking when its not starting...

If the FPR is going out both of these test should be "OK", not to say that the computer isnt bad but that would be the absolute last thing I would replace... unless you have one you could throw in just to test real quick...

I've heard of corroded wires near the fuel pump causing this type of problem, but since you changed the fuel pump that probably isn't your problem. I'd check fuel pump wires all the way around though.

My bet is that it is your coil...

I have had the very same problems that you have posted on two different rigs....

Ended up changing the coil...Problem solved...

That's what happens when those electronic coils start to go bad.

Edit, with tech
The key symptom is that it starts to stumble and die when you press the accelerator. Doing so increases density of air/fuel in the combustion chamber and thus the resistance across the plug gap. A weak coil can often jump the gap at idle, but not when the throttle is opened up some.

On my Sammi, this would happen after driving for 10-15 minutes. It would run fine after the engine cooled for a while (even though the coil is in the passenger compartment).
