How to remove ignition control module Videos

We have a lennox pulse 21. We are having a problem with it right now. we have no heat the furnace will run, but blow cold air. I found that the green light on the control is off. So I shut the power off what a few seconds and turn it back on and then the green light comes on and we have heat till the temperature reaches what we want. Then the next time it kicks back on I have to go turn the power off again. Is the controller bad do we need a new one? We have a 86H3001. Will the new one in your video work?

Good video, thanks for posting

Thanks ! My SC-2 it's my better car since my SC '92...

Very useful tip. My SC-2 '98 maybe need a good cleaning ...Yes ! My car is top shape with 184 K Kilometers on odometer...

Awesome...thanks bro!

Wow.

Hello...Okay so I have a 1997 Saturn SC1 automatic and NO P0742 I have TWO P0300 and P0340 codes so I got ALL the stuff too reove the coil and clean it but was wondering on that "TORQUE" tightning WHAT would I tell Autozone I need in order too not tighten them too tight? I cant just hand tighten them since I'm a gurl? LoL thanx I will let you know how it runs when I'm done =)

Hi, I followed you instructions on replacing the Ignition Modules it fixed about 95% of the problem. The car still idles very low at stop light and stop signs and will occasionally die. I am not sure what I could do to stop this from happening. What would you suggest? Thank You, Steve

Thanks for posting, I just bought a Satun SC2 and we love it. I've had some miss fire when I first start in the morning and at night when I leave work, but as I drive for a little while it the miss clears up. No engin light either, so no codes. I replaced the MAP and Temp sensors, but the miss still happens on start up. I'll try this cleaning this weekend and see what happens. Thanks again. Dan

AWESOME video....I have P0340...PO300 and a PO742 codes 1997 Saturn SC1(141K on it)and I checked for spark on ignition coils NO spark on 4 & 1 but car still started when I took wires off of those then last 2 had spark but engine wouldn't start with those wires off....I'm worried about the P0742 code but as U prob know car sounds like a SCOOTER & wont hardly move but will not drive it until fixed.....What is with the P0742 code? When car had NO codes and was driving fine tranny was fine.....Previous owner was a douche nozzle and he never even changed the oil(its at about 6K miles but will change SOON) as well as ALL other fluids thanx U are awesome!!!! I thought I could clean these myself until U said the bolts going back on have too be tighten too a certain extent instead of me going by just tightening them as normal lol

It doesn't really sound like a fuel pump issue. Usually the car wont run at all if the fuel pump fails, regardless if the MAP sensor is plugged in or not. What year Mustang do you have? Does it smoke at all when running with the MAP sensor unplugged? My initial guesses are O2 sensors, fuel pressure regulator or EGR, but its difficult to tell without knowing more about the car. Was it running poorly before it stopped working?

Hey Chico Great information There's a rv just like yours for sale around the block from my house They want 30,000 for it I sure hope you get yours running soon Would love to see you out traveling or camping liked( thumbs up )

I have the same motor in a saturn vue with no spark and no fuel pressure.

hello scannerdanner love ur videos, my question is how to test a cop coil with test light. I hock up test light crank the engine, if i have spark should get a spark from coil to test light right. i dont need to stick light down the coil boot right just above it right.

ScannerDanner, 1st off thanks a million for the best diagnostic video on the net. My question is DOES GM MOST GM DEALERS HAVE THAT DIAGNOSTIC HARNESS U MENTIONED?? I changed plugs n dont wanna waste $$ replacing working parts..

I have a 2003 Saturn Ion 2 , My engine light came on an I got a sudden loss of power and the engine ran hard. I took it down to a auto part store an the tester said 3 cylinders . So I took it for a tune up , and had the plugs changed. After the mechanic said I need a Ignition coil an a module, After changing the plugs it still was back firing an still loss of power , do you think I need both parts and if I tried to replace it myself , I can save $100 but never did this before , any ideas on this will help , Im disabled an on a fixed income an don't have the money to keep pouring it in by trusting a unknown mechanic. I didn't see Him using such a machine to test the coil or module. thanks

I found out it was my ICM..just like you explained in your video ..the ICM was stopping my car from starting(firing)..thank you so much for making detailed videos..

Hi I have the exact same car and year as this video..I have a question..my car cranks but won't start..my fuel pump is on and running,my battery is good and my spark plugs are new..could a ignition control module not let the car start ? like I said it cranks strong but doesn't start at all..also we tryed spraying starting fluid and got nothing as well..please help..

Like Eric the car guy called u once, Frankenstein or Eiestein, hey, just kidding, always great videos, ive always wanted to comment, and now that I upgraded from xp windows to windows 7 I can. so just wanted to let u know your videos are fantastic. see ya sir

i have a Saturn 2005 ion auto.. that doesn't go reverse but everything else works perfectly & no one here where i live can tell me what is wrong with it :( 

Great video. I always seem to like watching your case studies/field work more than your classroom setting in premium. Don't get me wrong, I try to watch every premium video I can because it's incredible information for $10 a month. It's just not as enjoyable to watch. I especially enjoy watching you live in the field (like that mercury fuel pump issue at your friend's Petes garage). 

Great job, it feels good when you don't have to worry about something burning up or burning a place down lot easier to go to sleep at night! Some of those old controls just didn't hold up good thing they are better replacements now! I hope you got to enjoy the rest of your day! Take care

Gary, I have a 1,000,000 btu boiler (car wash). The pilot lights the main burner lights then it immediately shuts down and starts again.. pilot-main burner-shut down. honeywell S86, the boiler is approx 15 years old. Any advise. Thanks

thank you, i found the problem on no heat you are the best on the net I have 30+ units and you are saving me some $$$

Really enjoy your videos. I do property management and it is good to know what is going on when the HVAC guys are doing service on the units. Curious, contractor just replaced one of these ignition modules because of no spark (and also the ignitor rod thing at the end of the cable). 2 weeks later, the new module isn't sparking. One thing I am curious about is the Ground to burner connection (like the one on the honeywell you showed in this video). Is it supposed to be connected to the "C" marking on the gas valve? Does the "C" stand for common? I see a "p" on the valve (guessing for Pilot) and a "M" (guessing for main valve) but wasn't sure what the C was for and why it connects to Ground Burner connection on the ignition module.

A have a question I'm working with the fenwall 35 series.sometimes the gas valve open at delay time after the ignitor lit up then it opens.eventually the the ignition module will lock out,I've replace the flame sensor and ignitor,gas pressure at the manifold are ok,air proofing switch close but what causes the delay?any idea,I've change the module still does the same thanks

Can you clean a spark ignitor, As a trouble shooting technique?

Hello GFM I have a 26 year old gas furnace with a spark ignition/sense in 1 line. The problem I am having is that the pilot lights, the main burners light, but it goes out after about 30 seconds to 1 minute and then immediately begins ignition sequence again and does this nonstop. I'm not sure what to check. The pressure switch has voltage in and out and it's constant so I don't believe that's the problem. I did notice the spark wire had a crack in the rubber around the part that connects near the pilot and was a little loose so i pushed it on really tight and it was fine for 2 weeks. But I just got a call and it's acting up again. Any thoughts?

Hello mr gfm. In a rooftop unit the trouble shooting say: you can see the light/spark working many times. But you can't see the flame on burners. There's gas on the pipe but after the main gas valve doesn't go gas through the burners? Do you think the problem is on the main gas valve?
