So I lend my jeep to a friend for a few weeks and go to drive the celica and find it running rough. After a bit of investigation Ive found the im getting a very small amount of spark from wire #4. So I did the usual swap plugs, new wires, new cap, new rotor...... Nothing, still a weak spark. So weak infact that its not even igniting fuel. Im not excited about the possibility of a pinched wire somewhere in the harness and im even less excited about the idea that I may have to hunt it down. So before I start pulling things apart let me go over what I know it isnt and hopefully someone will see light where I cannot.
out of the 3 mains (fuel,spark and air) Ive already figured out its the spark. Its only happening on the #4 wire Its not the plug, wire, distro cap, rotor as I have replaced them all. I AM getting spark but its very weak and at times not there at all. The old cap had burn/spark marks on the pins accept for the #4 one where it looked almost new. I cant see any pinched wires but that doesnt mean something has worked itself loose some where out of view. An option I have is running a MSD 6a ignition (if that would bypass my problem), Ive had one sitting on a shelf for almost 5 years and I have yet to install it. The only problem is I dont know how/which diagram to use for the install. /discuss ![]() This post has been edited by 1bwilson: Aug 29, 2008 - 7:04 PM -------------------- Member of Team 5sfTe

New distributer..... nadda.... sigh.
Going to pull the injectors out and reseat them hopping that theres the smallest possibility that its seated wrong and soaking the spark plug. The only problem is theres no sign of gas leak so I dont believe its going to change anything. After everything with this car its hard to believe that a weak spark may be the cause of its demise. Edit: Reseated and no change. Im at a loss as to what can be causing this. Ive swapped the plug out, replaces the distributer, rotor, cap and wires. Adjusted the timing and looked for any faulty wires in the harness (those I can see, havent cut into the harness).... Im about done with options here. Getting a new harness is about where I draw the line of worthless replacements (spent over $550 already replacing whats listed above). Feel free to toss any ideas out there no matter how strange.
