Re: The FINAL "problem starting engine" thread!!!!!

Marbie...

I have same issue. There are a # of things it can be. I just ran my car to a certified honda tech and he said Idle Air Control Valve (IACV) could be it (not in my case cuz just brouht a new one and still has same issue), #2 air bubbles in your antifreeze (which you need to bleed out & top off again), #3 vaccuum leak (change tubes), #4 map sensor, #5 fast idle throttle valve, #6 head gaskets, #7 throttle body. So I would go for the cheapest options and work from there narrowing it down.

I have a 93 Lude Vtec and thru the two months of research these problems are what Ive found to fix issues...

Good luck buddy...

What would cause an ignition coil to go bad frequently? ICM is brand new, rotor button new. Plugs and wires (NOT NEW).

Re: The FINAL "problem starting engine" thread!!!!!

Sorry to bring this old thread back but I now am having this issue. My 98 Prelude cranks and cranks but will not start.

What I have done so far:
Confirmed fuel
confirmed spark
checked timing
tried two different ignition control modules
changed Main relay
tried a different MAP sensor
changed distributor
The starter is only 6 months old
I unplugged the altenator
Cleaned the IACV and Fast idle
I tried another ECU
I also changed out the temp sensor
Spark plugs and wires are like 3 weeks old.

This car still will not start. What am I missing? And suggestions are appreciated. thanks.

Re: The FINAL "problem starting engine" thread!!!!!

I don't know if anybody will look at this but maybe it will help someone. After everything that I listed already, I tried some other stuff to but no go.

It ended up being what looks like a clogged EGR valve. Once I cleaned and scrapped this out, the car started!!!

Re: The FINAL "problem starting engine" thread!!!!!

i'm having trouble with starting, well it's just after starting. when i turn the key nothing comes on the dash at at until it gets to where it fires the starter, it fires up ok but when i let the key go the car stops and all lights go out on the dash. it will run if i hold it in the start position, i did that just to see what was happening, i know thats not good for my starter, i just wanted as much info as possible before asking questions here. anybody shed some light on this for me? it's a 93 2l.

Re: The FINAL "problem starting engine" thread!!!!!

Great Stuffz man! I need to check timing on mine. I have a 2000 Prelude with H23 Swap in it. Currently Everything is connected but the stupid Knock sensor that Broke on me. But! yeah I tried to crank yesterday after an extensive overhaul of H22 to H23 and all I get is Some backfires through Exhaust and Intake.. but no run. Gas = good Spark = good So last to check is timing :P

Once I had dead battery symptoms. New battery lasted three months and symptoms returned. My $20 tester said it was good so I bought those painted quick realease terminals since the car sat a lot. No go, and it wouldn't take a jump either. Battery tester at autozone indicated bad cell on a 3 month old battery. Swapped for new one. All was fine for 6 months.

Dead battery symptoms returned. Car would not take a jump but bump started. Battery good. Bad alternator. Replaced it with a prelude1897 unit. 2 weeks later, same $h!t. Bad alternator. Car wouldn't jump or bump.

The thin coat of paint on the terminals wouldn't allow proper current flow when the slightest corrosion set in. Fried 2 alternators. Paint was scraped off contact points and all is right with the car now.

If the car was running and dies, and won't restart (not battery related)....
I always cheat with a spritz of starter fluid. One squirt tells me fuel or electric. If it tries to go it aint likely electric.
If it's compression there were likely symptoms before the tragedy. Hard start, oil consumption, smoking. I say usually. Not always. Ring failure could come on suddenly, but not usually without warning unless you are really abusing the engine.

SOMETIMES hitting it with a hammer fixes it, if the problem is a frozen bendix. That's not going to solve it 100% of the time.

Have you tried the simple things first? Like a fully charged battery?

Re: The FINAL "problem starting engine" thread!!!!!

Chimney 101 post:
There seems to be an upswing in holding idle lately. And a general lack of knowledge has lead to a near daily thread about this subject. Much of these issues are simply soot build up in these older cars and can be solved with a little knowledge and a can of sea foam.
First a little history;
In the old days a combustion engine took in fuel, and put out exhaust. An easy process generally speaking. But that lead to polluted cities. So the goverment created rules force car makers to make cars that put out less pollution.
The catalytic convertor was picked by the industry.
At the time it met the rules. But the government updated the rules to require more effective pollution controls. Enter the EGR system...exhaust gasses recycler so-to-speak.
For this I won't go into specifics as to what those items do to prevent exhaust pollutants, so if you're curious look it up.

Now to the chimney part and how it relates to your malfunctioning automobile;
Fireplaces are a good thing. They put out heat, look cool, plus busting up your own firewood is a proven way to feel better and live longer.
A fire place uses fuel, just like a car. This case it's wood. The wood puts out pollution. Some wood puts out more 'soot' than other wood. This creates a layer on the chimney walls that has to be removed. Oak for example puts out less 'soot' than pine. Again I won't go into why, but it does.

In todays push button, gas log world the typical fire place doesn't need much of a chimney. Gas puts out little to no soot. But the folks who still use wood generally use the good stuff like oak, maple and other hard woods. They avoid wood like pine, cedar, and other soft woods because they 1) burn up faster, but 2) tend to coat the chimney with a layer of junk that when thick enough can catch fire and burn the house down.
Now folks also use a sorta throttle in their fireplace to throttle the smoke from time to time. All things done correctly, it cooks the layer of 'soot' lining the chimney walls. But even still a chimney cleaner is hired once or twice a year to ensure no chimney fire happens.

Now how does this relate to your car?
In the old days gasoline was like oak. Burned hot, and left little residue when all things were correct. Todays gasoline is like pine. It leaves residue from being blended with ethanol.
The modern car is engineered to reduce the residue. But our cars were engineered when there were generally little to no detergents, and no ethanol.
I mentioned throttling a chimney to cook the soot. Our cars are controlled by a computer that knows nothing about soot build up. It monitors air, spark and fuel, combining them to create as little 'nasty stuff' as practical. In essence it cools down the exhaust to prevent certain chemicals from forming and exiting the tail pipe.
The result is soot build up in the lungs of our cars. By now the Honda engineers knew the EGR system was a clog waiting to happen. So they designed 'cleanouts' in the intake manifolds. More than a simple unscrew a cap, ramrod the junk out and re-install cap is required though. It is known as "clean the EGR ports" to many. Yet an annual EGR valve check can prevent the soot build up. For city drivers, it probably needs to be checked more often.

More than likely your holding idle/resulting hard to start woes are NOT the IACV gone bad. But soot build up may be a factor in the open/close of the plunger. By the time your IACV plunger malfunctions due to soot build up, chances are good the rest of your air intake is also lined with it.
For those with tools, know how and time, a do it yourself 'chimney sweep' can be performed in a few hours. Sea foam sucked into the air intake through the vacuum system will remove much of the build up.
But that nasty ole EGR system is another matter. I can tell you from experience that the Honda engine isn't the only one plagued with EGR clog woes. So if your car is troubled with stumbling idle or hard to start, first check your distributor, for the condition of the cap and rotor button. Then ensure your wires are plugged up correctly, and the insulation is good. (A way to check that is run the car in a dark place or put a rain coat over you and check for lights flickering from the wires)
If all that checks out, peek inside the throttle body past the butterfly for soot. Remove the IACV and check for soot.Stick your pinky into the openings of the intake where the IACV was. Chances are both have a black powder inside. If so, your EGR system is likely loaded with it.
Many times cleaning the valve will help. But when you remove the valve, if the inlet is partially clogged, it's best at that point to remove the intake manifold to have the entire air intake system cleaned including the idle air bypass plate.
A good shop can do this using a BG system, but it aint cheap. Nor is paying them to manually clean the system. But once it's done, it'll take quite a while to clog again. For you city dwellers, go to a highway and drive for 30 minutes at a steady speed where the rpm's stay at about 3000+ to cook the soot about once each season. And STOP USING CHEAP GAS!!! It's like using pine in your fire place. They say "up to 10% ethanol" but studies (by Briggs & Stratton along with Toro) show the cheap stuff has as much as 30% in many cities.

Re: The FINAL "problem starting engine" thread!!!!!

Also note, our engines require valve adjustment from time to time. So if you know your cap n rotor, with wires are good, you've determined you get fire and fuel, the intake is pretty clean, then there's a good chance your valves may be out of adjustment leading to hard to start and vacuum issues that will also lead to more soot build up in time.

For the record, Mr. Honda had developed a system known as the CVCC that met the US governments pollution standards without the use of a catalytic convertor. But the EGR was used to prevent excess NOx (or something). So keep that in mind when the smog test says too much of that...could be the flow of the EGR is partially reduced.

Got a 4 cylinder with 8 spark plugs? That is a similar system to the CVCC but is also part of the EGR. Instead of simply passing it back through the intake like the H22, it 're-burns' the exhaust gases as well.
