TFI ignition upgrade.

I did it.. a while ago.

But I just put the new distributor parts and the coil in.

I don't remember readng anything about replacing the module.. but now I've done some searches and I can't find anything conclusive.

I was going to buy a spare.. and was wondering if I should (as per RRichs) suggetion... get a Ford one that'll hopefully not be the weak link as my Jeep one is right now.

Anyone?

Re: TFI ignition upgrade.

Well,
Here is what I learned. If you still have a resistance wire in your wiring harness you should be OK with the module. If the wire is removed sooner or later the module will probably burn out.

To run the module without the resistance wire you need to run a Duraspark II module, but the plugs and or the wiring that you have now may need to be changed to do it.

Now here is the problem I have had with the Duraspark II module, I can't find one! I looked in the yards and went to the parts stores and the Motorcraft site and they all have the same module that matches the Duraspark (I)configuration.

Search under my name and you should find my drawn out ignition problem post.

Re: TFI ignition upgrade.

Have you got an ID method?

There's a yard around here that does LOTS of Ford stuff.

Re: TFI ignition upgrade.

I think it's the wrong tree you are barking up -- woof woof woof. But maybe not.
Modules, and coils, can fail without getting hot. But hot indicates potential failure. Once they fail, they usually get cold again as no current's flowing.

The parts guy that told you $280 for a module looked up the wrong thing. That's more like for the computer.
Try a different place, give then an IQ test first - must be over 6!

The Jeep used the Ford Module - samo samo - Duraspark I.
They run between $25-45, depending on where you get them.
Take your old one in with you.
Seems like I heard Wal-Mart has them for $20? Not sure.

So you got it to work without dying? What did you say about your ignition switch =- something like you were holding it? It wasn't clear.
Could be the problem child - does the switch or key get warm at all? Warm indicates too much resistance. Not positive proof, just an indication. Next time try wiggling it while it's dead to see if there's any change.

Your question about exhaust being plugged - I tried to address that long ago with the vacuum gauge. Still a possibility.
Try that cheap module.

Re: TFI ignition upgrade.

The module the guy showed me was exactly the same as the one leve posted a picture of in the other thread.

I got the jeep to run up and not do it's little bumping thing it used to.

To do this.. I bypassed the mechanical pump... the fuel filter, and put the old cylindrical coil back on. (instead of the ford one)

After that it ran fine.

My question now is..
On monday.. when I go over it all again.. and mount the pump properly/wire everything.. and so on...

is there a way I can get the DuraSpark 2 in there instead of the #1.. as it was pointed out in another post, it's a better module.. and wont burn out..atleast thats what i read.

Re: TFI ignition upgrade.

Sorry Leve.. :P

I understand what your getting at.. but when I have to go buy a new module.. I'd rather get the good one instead of the bad one.

As it stands now. I drive back to school today/tonight.

Hopefully.. I'll be back on here tonight.. giving you guys all the details of how it goes.. hopefuly.. it goes well and I don't crawl home in lowrange 1st on the highway. [img]images/graemlins/laugh.gif[/img]

Also, it isn't completely outragous that the module is $200+.. cause they want $500 for an MSD here. [img]images/graemlins/grin.gif[/img]

Re: TFI ignition upgrade.

Well it runs..

Sort of.

I've almost eliminated the problem.
Using the old coil.. (stock)

Tomorrow i'm going to tune the carb.. fix the ehxaust leak.. check the timing.. and some other bits and peices.

BUT.. my new resoltuion is not to put another penny in my engine unless its to keep it running.

This summer will be swap time.
My engine is well past worn.. burns oil in #6, has the bottom end rattle.. leaks oil from the front.. back and center... I think it's coming to the end of its life. [img]images/graemlins/frown.gif[/img]
