Auto Parts: 1986 ford ranger 4wd 2.9 ltr, side fender, pep boys


Question
I have power to my coil but no spark from coil to the distributor. I have replaced the coil thinking it was bad but I still have the same problem. while I was checking for spark at the coil my daughter turned off the truck and a little inch square by 2 inch long box right next to the voltage regulator on the passenger side fender well kept ticking after she turned the truck off. Does that little box have something to do with the spark from the coil to the distributor. Am I missing something simple or is this a complex issue. What else would control the spark if the power going into the coil is good

Answer
Hi Bruce,

One word: Duraspark.

The Duraspark ignition module is probably bad. It was a very common issue with that era Ford trucks.

I haven't a clue what the clicking box is or why it would be clicking with the key OFF.

Looking for a reputable service technician? My advice on finding a good technician is: Steer clear of the dealership and 'chain' stores like Firestone, Sears, Pep Boys, Monro Muffler/Brake, Midas, etc. as they usually only employ ONE ASE Certified Tech just so they can say they do and chances are, that guy is the asst. manager or manager and is not in the store to diagnose/repair vehicles anyway. Find a service location in the link below or get some names out of the yellow-pages and do a drive-by. Garages that employ ASE Certified Technicians will be marked with the 'Blue-Seal' insignia. If unsure about whether a place employs Certified Techs, just ask to see their credentials. ALL ASE Certified Technicians will be PROUD to show and display their certificate(s).

Thanks for the question, I hope this information was helpful to you.
