V6, 5speed brought me home last night as usual. This morning, no start. Turns over, but no fire. Pulled a plug wire and don't see any spark. This is my daily driver, really have to get it running. Where do I start? I havn't used the search function yet, I've been side tracked with another million or two projects today, forgive me. Thanks in advance.

I picked up a manual, and started some diagnostic testing. The secondary circut resistance check of the coil gave me a reading of 18.5 ohms....the manual says the correct range is 10.2-13.8k ohms. So I guess I'll replace the coil tomorrow.

first question:

did you do your spark plug test right? Did you touch the metal of the spark plug (the bolt part) to the engine block when you were turning over?

second question:

is your starter relay grounded?

mt4runner

Yea, Did the spark test correctly. Tell me more about the starter relay. Where is it located and how do I test it?
Thanks

starter relay is in the fuse panel under the hood. the cover will tell you which relay is for the starter, you can swap it with the efi relay and see what happens

In my 4runner its under the driver side kick panel.

also... make sure igniter assembly is properly mounted / grounded and that there is no... junk stuck in there...

its:



dist plugs into it

abecedarian

that looks nothing like the ignitor / coil assy on my 88 or 91.

Thanks for all the replies. I will check out the relay. My igniter assembly seems to be solid and secure. Really clean under the hood, but I suppose that it could still be an issue

here's my 91:

He has a 3.0L

If you need that part i have mine up for sale.

My 93 looks like ragon's, but my 86 looks like abecedarian's...

Well, I found my starter relay, its near the driver's side kick panel. My efi relay is under the hood and the relay is round, while the starter relay is square. Will they still interchange? Also, I'll be darned if I can get the starter relay off, my fat fingers can't get to the clips. So, did the repair manual steer me wrong? My diagnosis per their instuctions show a faulty coil. Are they leaving out some other diagnostics that could affect the reading on the coil?
Patiently learning, Rick

My '91 looks like Ragons' as well.

abecedarian

Well it seems everyone has it all figured out: the engine cranks over (which rules out the starter relay) but it must be the starter relay?

same problem with my 95 3.slow take off the main cable to the starter located next to the passenger front tire and clean the main cable that goes to it and it should start right up!

22re to be precise

I had 95 4runner did same thing! Try beating on the ignitor with a lil hammer i beat it will fix it!!! Thats all it was on my 95!!!

She's up and running! Installed the new coil, confidently crawled in to the cab, hit the switch.........and ..........nothing. So what gives? I tested the coil at least half a dozen times. Same reading each time, 18.5k. O.K. so now I go to test the pickups, pop the cap and the rotor is toast, I mean really gone and the cap doesn't look so hot either. So I picked up one of each, wanted to go OEM but the dealership is 60 mi.away and I have to get it running, so settled for Borg Warner. Pulled the pick-up coil connector, and kinda got some readings, couldn't get the female end off the wire protector cover to save my soul and didn't want to break it, so I tried top do it where it sat...not fun. Got brief readings, seemed o.k., so I put it back together, and bingo, fired right up! Got rid of the occasional low rpm stumble too. So, I know the the coil taking a hit and the rotor/cap going bad at the exact same time is highly unlikely, but stranger things have happened. Suppose the fuel mileage will go up a little too. I'm anxious to see by how much, as I was getting 19-21 on the hiway/13-16/town before. Thanks for all the suggestions.

I need to know what to do , the toyota wont start. There is power up to the coil but nothing after that , There is nothing to the distributor cap. It wants to start . It was running and then nothing, It just died
