 Subject: MSD 6A Problem
IP: Logged
Message:
I installed an MSD 6A on my '97 3.9 and it wouldn't start. I checked the wiring a thousand times and couldn't find anything wrong.
I have Accel 8mm Extreme 9000 Ferro-Spiral Core wires and Bosch Platinum +4 plugs. Could that cause the problem?
Any ideas? Thanks in advance!

You used the correct diagram right? There were a few different diagrams that come with that module. I installed the 6A with no problems on my '92 318. I also used the MSD Blaster SS Coil, but that shouldn't make a difference at this point.

I hope so. It was the diagram for 'late model Dodge with 2 pin connector'. Everything was right down to the color of the connectors to the coil.
If it's not the wires or plugs - I am out of ideas...

I'm not sure what else to recommend. Was there anything else that you did (another mod) at the same time that could be causing it to not start? Depending on what you used for connections can you plug in the coil with the original wiring and see if it starts then? It is a possibility that you got a bad unit, but I would make damn sure that you check each and every connection and probably use a test light too before you spend your time sending the old one back and everything. Make sure that you have all the right colors going to the right wires. Could you maybe have the module's input/output wires switched around? Check to see if you have power and ground coming to the coil with a testlight (check it right at the coil connector). You should either have voltage or ground all the time (maybe with key ON), and then the other wire should flash when you're cranking the engine. I hope this helps a little.

Mark, thanks for the input. As a matter of fact I just wired up only the blaster coil by itself using the original wiring and the ballast resistor. Works fine!
I checked with test light and voltmeter and with the the 6A connected, both wires going from the module to the coil have 12V..? have to check what it is when cranking. I am also going to recheck the supply to the module although I wasn't high when doing them... but you never know.
After all that and if it's not the connections, not the coil, not the ignition wires, not the plugs... I have sent msd an email, maybe they know something.

MSD has actually answered and according to them, the plug wires and plugs are not the problem. Back to square one. I'll just check and recheck everything again and run through the trouble shooting part of the manual. Hopefully something turns up...

I had this same problem with my 98 V-6 Dak. Your the first person from what I've seen to duplicate my problem. I took mine to the dealer with this problem and they looked it up on the codes as to why it wasn't starting and the codes were all ignition codes. Dealer said it had to be a bad MSD box. I sold it to a guy who put it on a new Mustang and he had no problems so I truely can't say what the heck the problem is. I know MSD recomends not to use the platnum plugs but that wouldn't cause this problem anyway. I had the MSD-6a Offroad box so I don't think theres any difference from yours and the offroad version. One other thing the dealer noticed was that the box was advancing the timing to far. I've got into some serious arguments with guys on this forum and Dakotausa forum that the MSD box doesn't advance the timing but I'm here to say it does. The dealer mechanic I had did see this problem before and he said the Jet chip does tend to conflict with the MSD box. I would put one by them selves and it ran great but once the two were on together it would not start at times or just konk out for no reason. I've been debating buying a new one thinking it was just that box but I would still like to know for sure what the problem was. I hope there are some people out there that might have some good input as to what it could be.
Wouldn't want any other!

Is it true that you aren't supposed to use platinums with the 6a? I heard it somewhere, but never confirmed it. Thanks.

Thanks for all the input! I haven't had time to work on the problem today. Hope I can do something tomorrow...
Stealwings, I don't have the Jet Chip installed and it still doesn't work. Computer-wise I am all stock.
mo-par, are there different versions of the 6A ignition? When ordering, there weren't any options to choose from...
crapshoveler, in the response from MSD they say something like 'while we don't recommend the platinum plugs, they wouldn't cause the engine not to start'. I don't know why the platinums are not recommended though...

92 4x4, I installed the MSD 6A, Blaster SS Coil, and the Mopar Perf Computer all at the same time. I did notice a difference. One of the things that is advertised and what people say is that it will make it start faster...I haven't noticed that. But between those three installations I did have a noticable increase. Although I have many other mods that may take advantage of it more than others.

I have an MSD 6a installed on a 97 v6 with msd superconductor wires and an accel high output coil with Bosch Platinum +4 plugs. To date, I have had no problems. In fact the MSD smoothed out the idle.

mo-par I have no idea what you mean by odd fire for the V-6 as it fires every 120 degrees of rotation the 90 degree block is corrected by a 30 degree offset in the crank so it is actually firing evenly. you can double check this by checking the spacing of the terminals in the distributor, and they are evenly spaced. If you mean odd firing order, well that does not apply here either as "any" firing order can be correct. Since the ignition distribution system is not effected how would the ignition spark generation system be effected?

Ok I think I know your problem its the way you have it wired up I will not start. The MSD6A has one wire off the MSD6A that needs to go to the coil and the other comes off of the oringal Coil wiring harness the small red one is off the MSD box and the gray one is the one of the coil try hooking those to up and I guarantee it will fire. Hopefully this helps

Maybe in my case the Jet chip won't work right with the MSD box but to be honest I'd rather have the chip than the box. I never really saw any difference with the box except the smoother idle and easier starts.
Wouldn't want any other!
