1994 4Runner no spark, engine turns, Code 12, =Broken timing Belt

So it drove 200 miles camped dirt roads, then died at a stop light by my house withno warning, won’t restart. starter turns/cranks. no spark as starter fluid does nothing. Fuse? ignitor?
Im hoping someone had this issue.

 

Can you hook that gen up to a scan tool?

 

I think I have to do the paper clip thing on the odb and count the lights... guess Ill have to do that?

 

Electrical malfunctions can be extremely hard to diagnose without some analytics. You end up guessing, and it can get expensive, unless you have a donor vehicle and you can swap out parts.

 

So by no spark because starter fluid does nothing. Did you actually test for spark or just assuming no spark because starter fluid doesn't work?

Guess you ruled out a fuel supply issue.

 

I did rule out fuel supply, I do have a donor vehicle, I was about to start following from ingnitor-distributer ect.
would that be what you all would do, or should I just see if I can pull a code? I was hoping it was a fuse I was missing but switched out a couple from spare vehicle with no changes.

 

For sure, I'd try and see if it was showing any codes. With donor parts, just be methodical until you find it, maybe take notes and photos while you do it. At least you don't have to buy those expensive parts you're experimenting with!

 

I would suggest not just guessing and swapping parts.

Check for spark first and go from there.

 

Toyota 1990-1995 vehicles obd1 code retrieval
When the check engine light shows up in your 1990-95 Toyota vehicle, the quickest way to get the code is to access the diagnostic connector in the engine compartment ( usually sitting in the fender) or by the kick panel under the dash board in the passenger side. Connect a jumper wire between terminals TE1 and E1 terminals and by turning the key on, it will start flashing the codes in your dash. On Tercel and MR2, use the jumper wire between terminals T and E1 instead.

If there are no codes, the check engine light will flash 2 times per second CONSTANTLY with no patterns or pauses. If there are any codes, it will be shown in 2 digits codes. Example: code 24 is shown as 2 flashes, a pause followed by 4 flashes. If there are mode codes, the next one will transmitted after 2.5 seconds. (One some models, codes are displayed in one digit code only and the difference is the codes are displayed with 4.5 seconds delay between codes). When finished reading the codes, turn the key off and remove the jumper wire.

Shown below is an example of the location of the diagnostic connector.

Here are the common codes for Toyota vehicles 1988-95:

Code 11 Momentary interruption in power supply to ECU (electronic control unit or computer) up to 1991
Code 12 Engine revolution signal missing
Code 13 Rpm signal to ecu missing above 1000 rpm
Code 14 Igniter signal to ecu missing
Code 16 A/T control signal missing from ecu
Code 21 Main oxygen sensor signal fault
Code 22 Water temperature sensor circuit fault
Code 23 and 24 Intake air temperature signal fault
Code 25 Air/fuel ratio LEAN
Code 26 Air/fuel ratio RICH
Code 27 Sub-oxygen sensor signal or heater circuit fault
Code 28 No.2 oxygen sensor/heater signal fault
Code 31 and 32 Air flow meter circuit or Vacuum sensor signal fault
Code 34 and 36 Turbo-charging pressure signal fault
Code 35 Altitude compensation sensor signal fault
Code 41 Throttle position circuit fault
Code 42 Vehicle speed sensor circuit
Code 43 No starter signal to the ecu
Code 51 AC signal on; DL contact off (in trany shifter with diagnostic connector jumped)
Code 52, 53 and 55 Knock sensor fault
Code 71 EGR system malfunction
Code 72 Fuel cut solenoid signal fault
Code 78 Fuel pump control signal fault
Code 81, 83, 84 and 85 TCM communication fault

 

Ok checked for spark, as suspected there was none, used method dirscribed above (Thankyou!) I got code 12
Engine revolution signal missing...?
ideas?
Im hoping rotor in Distributer

 

Crank position sensor?

 

ok distributor looks old and worn/dirty and is not turning when cranking over, belts and fan are moving

 

I just re-furbished a '95 4runner. Went with plugs, wires, etc. It made a difference. You should have seen the plugs! I bet they had 250k on them.

 

Well swapped distributor and still no spark... starter is turning engine and belts over. im stumped.. ingitor? is there a way to bridge across it?

 

If your distributor isn’t turning I would check to see if your timing belt is broken.

 

UPDATE,
Found it had a Broken Timingbelt!
First one of my life. at idle at a stop light..
Well time to fix. Thanks for all your help everyone!

 

Yep. That will keep it from starting. Thanx for the update!
