1991 Toyota Celica GTS 5A-FE. Engine runs great then I loose all spark which was verified at the coil. Replaced Coil, igniter (used), ECU (USED), ignition switch, Distributor. Checked all wires. will restart after playing around in coil area. Verified power is reaching coil. Removed coil and cleaned up grounding point but have not road tested. Burned up 8 starters in 3 months. Sometimes Voltage low at starter coil. I added a relay and have no additional problems. I have a Natural safety switch on order as I may have a thermal problem with contacts. Could not find any problem with wiring

You can follow a few methods to see if the ECM (Engine Control Module) is communicating with the ignition coil: 1. Scanner tools: Check for any diagnostic trouble codes (DTCs) associated with the ignition system or ECM by connecting a scan tool to the OBD-II port on your car. This can provide you with information about any ECM problems. 2. Examine the wiring: Examine the wiring and connections between the ignition coil and the ECM. Check the wiring and connections for any loose, rusted, or damaged parts. Any broken wire or connectors should be repaired or replaced. Make that the ignition coil is receiving power and ground by checking the power and ground. When the key is switched on, use a voltmeter to check for voltage at the positive terminal of the ignition coil. Verify that there is continuity between the coil's negative terminal and ground. In some automobiles, the ignition module that regulates the ignition coil must be checked. You might need to test the ignition module in your car to make sure it's working properly. If all other potential explanations have been ruled out, you may need to test the ECM directly. However, because this can be a challenging and complicated task, it may be better to enlist the aid of a qualified car electrician or mechanic.

Hi,
Did you verify if it has a main fuse for the ignition?...Link attached shows the fuses listed in the Owner's Manual and there's a IGNITION fuse that may be suspect...or some other 'main EGI/ECU' type fuse.

RAV4 repair manuals

need do a tune up change spark plugs and wires.clean fuel injectors and change fuel filter.if engine equiped with distributor replace distributor cap and rotor.if vechicle still misses.could have bad ignition coil or cylinders have low compression.

I'm going to guess TIMING BELT. Fairly common with this engine. Thankfully, they are a "NON-interference" motor so it didn't do any damage when the belt snapped. Just need to replace it. Should cost around $300-$400 depending on where you are. Good luck!

try reseting the alarm,maybe all thats needed.....

timing issue sound correct

pull off the front cover to verify cam/crank alignment marks?

when you say "new" engine do you me retail "new" or "new" for you

in other words, if you bought it second hand then you may have a NEW problem

My experience with Bosch ignition system (found on european cars) is the spark control is sent by the ignition module. The ignition module has to receive an input usually from a crankshaft sensor. This is usually near the crankshaft pulley on many cars. I am currently working on a 04 Toyota RAV4 and it has exactly that. If your sensor wiring gets loose or a bad wire then the computer won't signal for spark. This may not be your problem but it sounds like it probably is.
(By the way on my Alfa Romeo it is a sensor around the bell housing that senses the teeth on the flywheel) Good luck!

I would check the coil and coil wire. Check for spark from the plug coming from the coil. Also check your distributor rotor and cap.

check the engine ground strap

is the timing belt ok? there is also an igniter that controles the spark shoud be by the coil
