Question about 1986 Toyota Cressida
My car died at a red light coming home from work just stopped running. ive texted all the fuses and starter still wont start ive changed the cap and rotor and spark plugs still no start. the car cranks but wont kick over ive tried starter fluid to see if it was a fuel issue still no start any ideas
If it won't run on starting fluid then you have a no spark issue. i'd check spark out of the coil to the distributor. you could have a bad ignition control module or coil

Crank engine with distributor cap removed, is it turning?
(That is if it has a distributor cap, some newer cars don’t have one)is it turning?
Broken timing belt or chain?
Are you getting power to the + positive side of the coil (small wires) with key on ? Hint; I use a needle pushed into the back of the plug so as not to damage the wiring.
If you have power then wiring from the ignition switch is OK. It usually is.
Hook your test light to the - negative side of the coil (one end on the - terminal and the other end on a ground). You should have power on the - side of the coil with the key on and engine off.
Crank the engine while watching the test light. Get a flashing signal at the test light when cranking?
If so and you have no spark the coil is likely dead.(don’t rely merely on resistance tests for a coil, a weak coil can test ok for resistance but still give no spark.It happens but is unusual. I learned this the hard way!)
No flashing signal?
Check continuity in all primary circuit wiring for opens.
If they are good,
It is time to check the pulse generator in the distributor. (That is if it has a distributor cap, some newer cars don’t have one, if it doesn’t then the ECM or computer sends signal via the crankshaft position sensor and the camshaft position sensor)
With the engine in non-running condition connect your A/C voltmeter to the pair of wires at the pulse generator and crank the engine. You are looking for an A/C signal that makes 4-6 volts of A/C. Got this? If so the ignition module is dead or has a bad ground. If not (more likely) you have a dead pulse generator in the distributor.
If you have three wires in the distributor signal wire you have a Hall effect sensor. I forget how to test that one. (Chrysler stuff)
If this part of the primary ignition tests ok then check wiring to ECM pinouts for opens.Wiring tests ok.ECM as last resort.
Hope this helps...........

Testimonial: "Fantastic! Thanks for the insight and suggestions!"
SOURCE: 1994 Toyota Camry Won't start.
you should check 3 things. AIr, Fuel, and "spark"
your cars could have many problems. Ignition module, fuel injectors, Mass Airflow Sensor.
You should check into all of these 3 things.
a crank-no start could be many things.
it could even be a cam positions sensors resistance going up when the engine heats up. Cracnk- no start means testing. n like i said
The motor is getting Air, There is Fuel being put into the cylinders, and the Spark plugs are firing.

need to change rotor and cap , and might as well change wires and spark plugs if its due for a tuneup! yeah have your ignition control module check if it doesn't start after replacing every thing else.

crankshaft sensor, or computer on toyotas then it was usually the distributor or the computer, but the crankshaft sensor might be bad too thats what helps to get you spark.
