Overheated due to a failed T stat which was replaced

Car: Honda, Accord, 1993     -    Back to Fix-It    -    Honda Accord Repair Manuals

Q.I'm working on a 93 Honda Accord.
Vehicle overheated due to a failed T stat which was replaced. Ever since, have had an ignition problem. Sometimes I can get it to start for a few seconds then the spark stops. When I crank the engine with the coil wire pulled from the distributor and hold the lead up to ground I only get an occassional spark. Is there any one electrical component in this year Honda that would be likely to fail if it was overheated such as the coil?
Is there a way that I can bypass the ignition switch and supply current directly to the ignition system so as to eliminate the ignition switch as a possible problem?
The two leads coming out of my distributor are a two wire plug and an 8 wire plug. I have a 4 wire plug going into the back of the ignition coil. Hope you can give me some advise on this one.

Answer
I suspect a bad igniter. You will need to test it first.
Remove the distributor cap, rotor and the inner cover.
Disconnect the black/yellow, light green, yellow/green and blue wires from the igniter.
Check for voltage between the black/yellow wire and ground. Battery voltage should be present with the ignition ON. If voltage is not present, check the black/yellow wire between the ignition coil and the igniter.
Check for voltage between the light green wire and ground. Battery voltage should be present with the ignition ON. If voltage is not present, check the ignition coil and the light green (black/white) wire between the ignition coil and the igniter.
Turn the ignition switch OFF.
Check the yellow/green wire between the engine control module and the igniter for continuity. Also check the blue wire between the tachometer and the igniter for continuity.
Check the resistance between the terminals which connect to the blue and light green wires. It should be between 1,100-3,300 ohms. If not, the igniter must be replaced.

Additionand thanks for the information. Questions. In step 3 you suggest If voltage is not present, check the black/yellow wire between the ignition coil and the igniter. Check this wire for what exactly, continuity, voltage? It sounds like I should also have 12V at the ignition coil where this black/yellow wire connects and if not, where do I look from there for my voltage problem? In step 4 you say If voltage is not present, check the ignition coil and the light green (black/white) wire between the ignition coil and the igniter. Again, check it for what and if voltage is not present then where do I go from there? I'll make the tests you suggest and get back to you. Thanks again

AdditionOn a totally separate matter. I'm happy to pay you for this question in addition to the one you're working on for the 93 Accord. I'm now working on a 1999 Honda Passport 2WD V6. Can you give me the detailed service procedure for replacing the thermostat. At first glance it looks like the thermostat otlet pipe is connected to the lower radiator hose and that the thermostat may be located where this outlet pipe bolts onto the engine. If this is where the t/stat is located then it also seems that in order to remove it I would have to remove the entier intake manifold? Let me know where the t/stat is located and how to remove it and approx. Labor time?

Answer Step 3) check for broken wire (continuity)
Step 4) Same, continuity Passport

Addition While I appreciate your interest, I have already pulled up the Auto Zone service procedure for removing the t/stat with the diagram.
I don't need some over the counter referance advise. I'm looking for someone that has had experience in actually working on Honda's.
My question was "Can you give me the detailed service procedure for replacing the thermostat". and "approx. Labor time to remove it. NOT book time but actual experience time?
If you're you're a real Honda experienced mechanic then please answer my questions.

Answer No need for the sarcasim.
I have 30 years plus working on vehicles just like you'rs.. I gave you detailed instructions straight from the shop manual, i thought that being that you are a LAYMAN it would help to direct you to a site with pictures..
if thats the way you feel then i'll opt out and another expert can try to help you. You have to understand my position,,i dont have access to your vehicle or your knowledge of how to diagnose ignition issues.
No crystal ball here.

Addition Thanks for your reply and yes, based on your "off the web" answers, and not being able to answer my specific questions regarding detailed service procedures for replacing the t stat on the Passport, I would prefer that you release my question to another more qualified, or cooperative, real life tech that has actual hands on experience.

Answer Your first question was,
"Is there any one electrical component in this year Honda that would be likely to fail if it was overheated such as the coil? Is there a way that I can bypass the ignition switch and supply current directly to the ignition system so as to eliminate the ignition switch as a possible problem? " The answer is NO.
Then you asked another question,
"I'm now working on a 1999 Honda Passport 2WD V6. Can you give me the detailed service procedure for replacing the thermostat." Let me know where the t/stat is located and how to remove it"
I gave you detailed instructions for replacing the t-stat.. AND where it is located..
What more do you need?
Please refrain from the sarcasim, as it surely wont help in this matter.

Addition Sorry for my comments but I gave a price for changing this t/stat only to find out when I got the car that I have to remove the intake manifold to get to the t/stat housing.
It would have been nice to know that was part of the service procedure and that it would take about 3 hours to complete. That being said, I do appreciate your help and answers and am happy to accept both answers. Thanks

Addition I'm trying to clear up some of my pending questions and when I click on accept for your's the CRXSi.Com system tells me that I've already paid.
Can you confirm that you've received payment and that we're all square?
