I noticed that the cats have been removed from this car, would they make a difference in the way it runs?

Johnny Mullet · 08-23-2008, 04:53 PM

Mine has no cat and it runs just fine.

micali · 08-23-2008, 05:09 PM

thanks, that helps.

can anyone tell me what this part is? The vacume diagram doesn't show this part and where the two lines go. I think one line goes to the air cleaner and the other to one of the lines on the side of the TB.

here is a bigger picture

Can anyone take a picture of under the hood, without the air cleaner, of there 93 or newer metro? You can email me if you'd like. I just need some more assistance. Thanks so much
I am wanting to see where all of your vacume lines are hooked up. I;ve looked a the diagrams but I am unsure if I have all the lines in there correct spot.

We finally switched the TB out and intake because the one that was on the car was clogged. One of the EGR ports, in the intake, was clogged shut. We couldn't get it to clean out. We had another intake from the newer TB so we cleaned it up and used it. The same port of that intake was clean. I think we have all the sensors back where they are supposed to go but are unsure of just a couple vacume lines. Thanks for all the help.

Mine is a 1998 model and has a similar device. One of the large hoses goes to the evap canister (which yours is missing?) and the other goes through a hole in the driver's side fender well.

Here is my picture.....................

I think that's the A/C idle up controller. When you turn on the A/C, this provides a controlled vacuum leak to increase the idle. The screw adjusts the idle speed.

My evap canister is there. It is agianst the firewall. I guess there is a noticeble difference in the years.

I replaced the intake, TB, and EGR vlave I put all the parts on and the car won't fire.
I had to splice a new plug for the TPS sensor I just have those twisted together and taped for now. I believe all the vacume lines are hooked up correctly.
The car ran with the wrong TB on it, no map sensor hooked up, TPS rigged, hardly any vacume lines hooked up and I could drive the damn car. I can't get even a hint of fire. What gives? I will have to do more searching and get back with you.
We cleaned the TB out with water adn some cleaner the same for the intake. I've done the same for my camaro and impala when I had to tear them down to replace things. They ran jsut fine afterwards.

What should I look for?

anyone have any ideas? It just cranks.

Johnny Mullet · 09-25-2008, 09:24 PM

On page 1 DOCTORBILL told you to do a compression test. I have to agree with him on this matter.

micali · 09-25-2008, 10:37 PM

The car ran before we changed the TB. It was wrong of course and it needed to be corrected. I am just trying to figure out why it won't fire with everything hooked up correctly. The compression should be fine from when I brought it home until now. I can check it.

Some of us have been doing this for years and know what we are talking about. You said it ran before, but ran like crap and smoked, so I highly suggest doing the compression test. This will tell us how healthy the engine is internally. I don't understand why some people avoid doing the basics first...........

Air
Fuel
Spark
Compression

These are the 3 basic things an internal combustion engine needs to run.

First - Not trying to belittle your efforts, but you may have to take it to
a mechanic who may see, immediately, what is wrong!
They do this kind of thing every day - they live this stuff!

Second - from what you have said, it appears that the previous owner(s) have
boogered up the engine - just how badly have they done it!?

Third - This thread is getting confusing...

Make a simple list of what you have done - and the results. Post it here
so that we can easily follow this work! Please do it....

Fourth - DO THE FREAKING COMPRESSION TEST !

For an engine to run at all, many things need to be lined up and working sequentially and properly.

Check off list.....how many of these have you done?

Purchased a Chilton or Haynes Manual? w/o one you are fumbling around in the dark...

Are you getting a spark - yes? you can see it?

Do you have the timing set reasonably correct via rotating the distributor with a timing light - yes?

Are all of the spark plug wires going to their respective spark plugs? - Yes?
You would be surprised how many folks screw this part up!
Check the wires coming out of the Distributor....

Do you have the Timing Belt set properly - yes?
All the pulleys lined up with the main crank pulley?

A compression check shows high (>170 PSI) on each cylinder - yes?

Do you have good Vacuum ? If you have a blown Valve(s), you may have very poor vacuum....

You are getting gasoline delivered to the TBI - yes?

The TBI has a good ground wire attached to it - yes?

The MAP sensor is connected to the TBI in the proper place (Back of it) - yes?

The MAP sensor is connected to the Computer via the electrical connector - yes?

You don't have a short somewhere (THE most difficult thing to find...) ?

You have looked down the TBI when the engine is cranked
and see gasoline spraying from the Injector - yes?

If all these things are good, you ought to get some firing of the engine....

If not, come back here to the Forum and ask some more.

I had this same problem immediately after I rebuilt my 3 cyl engine.

The problem, apparently, was a bad or wrong MAP sensor because after changing that, it worked.

You may have a blown computer, but that would be very unusual as they are quite robust.

If you need lots of parts to try out, go to a local "Pull-n-Save" and get them CHEAP
off of olde used vehicles of the same year.

Can anyone else add more things to check - once the engine is running and
set up properly, these 3 cylinder Suzuki engines are sweet little babes!

I rest my case....

First,thanks for the suggestions,
Second just needed some ideas on what to check and I got that.
The reason the car ran bad was because nothing was hooked up correctly. The map sensor was not hooked, most if not all vacume lines were in the wrong spot or blocked off. That is why it was using fuel and smoking. The dang car was running super rich.
The big question for was, why after hooking everything back up why it wouldn't start. I know you wouldn't know but agian looking for a starting point. I know the importance of a compression test and have done them before. Since it ran that would be the last thing I was going to mess with.
I haven't had the chance to check for spark or all the usually stuff becuase of work.
I know nothing about these little cars but there isn't much to them so I figured seasoned owners would have a few suggestions. which you have posted.
I'll try them all and see what happens and agian thanks.

I'll even do a compression test!

micali · 10-03-2008, 08:28 PM

We'll we got the car to fire off but we do not see the injector spraying. We poured some gas in the TB and that's all the gas it was getting. We only had a little bit of time so we didn't get to see if it was pumping fuel but I would assume that the pump is working cause it ran before. I will swap out the injector from the other TB and see if that helps. All the fuses looked good.
