I am reading more and more posts that point to bad ignition modules. It must be that they were designed to last 20 years. I fixed my 1980 f150 three years ago. When the same symptoms appeared last summer on my 1983 Crown Vic, I knew exactly what to replace.

The f150 died at 2am after fishing. After walking for and hour I called a friend to come get me. We went back to the truck and it started right up. The next day I bought a new module and duck taped it in place. It has run perfectly for 3 years now (yes I eventually installed it w/o the tape). Point is, if you have an 80-86 F150 and it has not failed yet then you are on borrowed time. Go get a new one and be ready. I bought a B/W part.

 

i don't have problems with them to much. but if you wanna fix it, do the hei setup and put the hei module inside the cab like i did in my mustang to keep it cool

 

It was just $30 the replace and I figure it is good for another 20 years.

 

yeah but the Hei is a lot cheaper than that

 

I have had to replace four of them in my 1984 in 20 years. I finally went back to the duraspark II system

 

wtroger,

I guess my post should have been that some, perhaps many modules fail earlier but all fail after 20 years.

What do you want from an electrical part that's in such an abusive location as next to the engine. The temperature can range from below zero to 200+ deg in a matter of minutes. Vibrations, dirt, oil, & water.

20 years great- even 10 years seems pretty good to me.

Just my $0.02 cents worth.

 

Agreed, we just need to think of it like a tire or brake pad. Maybe add it to the list of replacement items everytime you roll the odometer.

 

I'm with you. My 1986 F800 used to not start once in a while or quit running. I did the usual testing then got my hands on a Mitchell Ignition Manual. The manual stated that if the engine died for no reason then change the module. I did and never had a problem again.

Of course we all know that the '80's were a testing ground for newer computer ignition systems and we all pay (paid) the price for new technology.
