FLOODED ENGINE? Non-Starter. Need help to diagnose

[NYNick]

Wish I could be more help. I"m rooting for you!

[thefaculty]

Thank you brother Nick!! lol - rooting for me is all I need right now. I am looking on the positive side. I am learning a lot about simple things and it's a great learning curve. Speaking of which - perhaps you can lend your thumbs-up or thumbs-down to today's test:

A timing light arrived today (figured I should add one to my growing list of necessary tools!) so I hokoed it up as you can see below to see if I have spark. I read on teh forums here that I could test my coil using a this method:

• Timing light positive connected to fuse panel.
• Ground to ground point next to coil.
• Sensor loosely around cable from coil to distributer.

If I have done this correctly (as shown by pic above) then I get the following:

• 12V ignition on
• 10V on crank
• Timing light does not light up or flash.

Having never used a timing light before I have no reference point to know if this is correctly wired up or not and therefore I don't know if the results are dependable. If I have done this correctly then I have no spark from coil to dizzy which rules out the dizzy correct?

So I looked again at the CDI:

• I checked power to CDI - it buzzes as it should and receives 12V from pin #15
• I have checked continuity on pins #7 & #31d and read 01.4 Ohms.

If this is also correct then I have a bad coil right?

Is that a Bosch silver coil made in Brazil?
Odds are it is a good candidate for the trash bin.
Timing light not flashing is a good indicator of a bad coil.
MSD Blaster 2 part # 82023 is a suitable replacement for original mounting location.

Thanks Denis - would you recommend going all out and upgrading/replacing the CDI with the full MSD system?:

PDan,

Is the silver ignition coil you have is the notorious Brazilian coil? The CDI plug should be connected and with the inductive timing light clamped at spark plug cable #1, turn the ignition switch to START and watch for the ignition signal (probe light). This is the basic procedure to verify presence of ignition signal for your motor. And don’t forget to press the trigger switch. I usually place a rubber band on the trigger switch during testing and start ups. Keep us posted.

Hey Tony - yes it is silver but I am not sure how to identify if it is the "Made in Brazil" one. I am guessing it is. I have just re-checked with the timing light. I originally had it on the wire from the coil to the distributer and got no flash. I rechecked (just to be sure because you had mentioned it above) spark club cable #1 and same result of course.

Just so we have gone over everything I have done I also did the following checks:

• CDI Plug measures 12V at pin #15.
• I also did a volt check at pins #7 & #31d and verified I have pulse.
• I also checked continuity at pins #7 & #31d and this reads 01.4 Ohms (is that ok?).

So coil? I think it must be right? If I am replacing the coil I wondering if going the full MSD upgrade would be worth it at this time?

Dan,

If I were doing the troubleshooting, I would first test and verify that I have a good ignition system and get the motor running. Keep it simple. Borrow or use a good ignition coil for the test. Once the motor is back running, then you could do your next project.

You could do what ever you want that you are comfortable. Keep us posted.

Dan, I’ve been running the Bosch CDI with the blaster coil for 9 years now.
As stated, swap out the coil for a known good one if you have one available.
Always Test and verify before replacing stuff.
One step at a time. Easy to throw money out the window just replacing things that don’t need replacing...

I went thru 2 coils before I remote mounted the 3rd coil off of the engine fan to the sidewall. Track driving induced high frequency vibration was removed as a factor.

Thanks Timmy - my mechanic is lending me one of his so hoping to do that tomorrow,
Great to know the Blaster works with the Bosch CDI. For some reason I thought they had to match makes. I'll get a coil to test and go from there.

Thanks everyone - will update asap.

Timmy - are you running the Resistor-less rotor with the Blaster coil or is that only necessary if you run the MSD box as well? I have read they need switching out but are hard to find.

[nomore]

In the photo it looks like the timing light clamp is grounded to
the spark plug wire sheathing. A grounded bolt on the chassis would be better: no?

[timmy2]

I use the normal SC Bosch rotor.
It is the MSD CDI that can have problems with the resistor type. Not the coil.

Pull plugs when tool arrives. Pull fuel pump relay.

Dry the plug ends out with a hair dryer or small flame.
Let it sit for an hour or more until smell of fuel is gone before replacing plugs and trying to start.

Dennis - I am continuing to diagnose this non-start issue and while I wait for a replacement coil to arrive I have been looking the the "Green Wire" and found some threads where you seem to know your stuff when it comes to this. I am a little fuzzy on all the thread I have read and am hoping you can clear this up for me:

• When testing for continuity between 7 & 31D I read 575 Ohms - is this good or bad?
• If I do need to replace my green wire I see you sell or can provide the connectors that will allow me to splice the wire that Pelican provide into the existing (good) green wire from the CDI. If so can you help me out with this?
• ...or - is this the connector I need: https://www.amazon.ca/Bosch-1287013003-Fuel-Injector-Connector/dp/B001CNZF7W/ref=sr_1_4?keywords=fuel+injector+connector+replac ement+kit&qid=1579628987&s=automotive&sr=1-4

Thanks Dennis! After a lot of reading today I think my Green Wire may be the culprit but I am unsure on if my tests are showing this to be correct or not. Any help you could give would be super! Thanks!!

[thefaculty]

I cannot tell you how happy I am to report back that the new coil arrived today, it went in and she started faster than ever before!!!

I cannot thank you guys all enough for your help, experience, wisdom and patience with me! For most of you this is simple stuff but for a newbie like me it's a milestone. Taking a car from a non-starter to a nice clean start without taking her to a shop is a big deal for me and I couldn't have done it without this forum!

THANK YOU EVERYONE!!!! And now enjoy the sweet sound of success!!

[timmy2]

Good news, and you learned a lot.

[NYNick]

Woohoo! Nothing like getting a car (any car, really) to start after it wouldn't. Good for you Dan, good for you!
