Driving down the interstate my 4Runner Misfired a couple of times, stalled, coasted to the side of the road and wouldn't start. Towed home, replaced Coil wire because I have had trouble with it and never got around to fixing it correctly, still no spark.

If I had a an intermittent coil wire could that have damaged something else in the ignition? Also I am using an MSD Coil.
Maybe this isn't related to the coil wire but I think it would be an odd coincidence if it was unrelated.

 

could be a fuse problem... or your dist. might have failed internally... a guy at work had a problem like that and when he popped the dist. cap the rotor came out in pieces...

 

Pulled Dist. Cap the rotor is still in one piece. How can i check to make sure the clearances are good? what is a good clearance?

Thanks

 

Ok fuses check out.. the main fuse under the hood by the battery, and the two fuses in the kick panel the 20a and 7.5a all check out good.

I am not getting spark at the coil wire. The igniter harness was corroded so i spayed with electrical connection cleaner and wire brushed it clean.

Still no spark at coil wire. Am I missing something? What could break while driving suddenly?

Please help I am stuck out of town until this is fixed.. also very limited on tools. I carry a 12 and 14 mm wrench, wire crimper/cutter and needle nose pliers in my truck. that is all i am working with.

 

Maybe the coil died? sorry not familiar with the msd coils

 

Replaced coil with new MSD Blaster SS coil same as the coil that has been installed, still no change in symptoms. Check ECU connections good clean and dry. Is there anyway to test the igniter? or should i just go get a new one and try it? Will an igniter fail on its own?

 

What does your timing belt look like?
Always cheapest to look around before buying anything
.

 

Timing Belt shouldn't be an issue.. engine cranks to well for that. I have had timing belts break and that normally shoves a valve through the top of a piston... but I made a cut out in my timing cover a long time ago with a removable rubber insert.. ill check it out.

Also I just ordered an ignitor so we will see what happens

 

I had this happen up on a trail, got stuck. it sucked, however i thought it was the coil, but it turned out to be the "engine" fuse on the kick panel on the drivers' side.

 

Double check the t-belt. The 3vze will not send valves into the pistons if it snaps. Mine snapped on me and I had similar problems..

My coil went at the same friggen time (replaced with used oem unit), it cranked all day long, had fuel... Pull the cap and crank the engine, see if the rotor rotates...

 

Yeah I broke the T belt on a couple of interference type engines and it did smash the odd valve or two. Fortunately the 3vze is a NON-interference. (So needless to say I haven't changed mine yet, 204k.)
I'm just spitballin' here.
Gonna be pretty hard to do anything with the tool list you had.
I'll go watch a few re-runs of mcgyver and post back the details of how to accomplish your mission.

 

will update progress tomorrow.. I'm done for the day

 

There is a way to test the ignitor, however I do not know it off the top off my head. The FSM outlines a testing procedure.

I would look at the Ignitor, or the distributor. The coil rarely, if ever fails.

 

The FSM does not tell how to test the ignitor, when it comes to troubleshooting the ignition it recommends trying a different ignitor.

The t-belt is good.

I'm just waiting on a new ignitor now, probably won't get here til thursday. I'll keep you guys updated.

Thanks for all the help

 

Thanks for the update.
Glad it wasn't the timing belt.

 

Ok got the ignitor in and I have spark at the coil. Replaced Dist cap and rotor due to 288000 miles and corrosion.
Now I'm still not getting spark at the plugs.

Any ideas?

Thanks for the help guys.

All of it checks out accept I still dont have spark at the plugs.

 

OK, how are u doing ur spark plug test?

i failed cus i didn't do it right. You are supposed to connect the metal part of the spark plug (the hex head) to the engine block and see if there is a spark in the tip If you are doing this then...
ur distributor is in wrong. pull it out carefully, clean it, put engine at TDC 1, install distributor pointing to #1 spark plug, bolt it down, and start ur car.

If that doesnt work, i can't help you T_T
