Toyota Repair Problems? Ask a Mechanic for Answers ASAP
hello and welcome
The 1997 model did not have a factory engine immobilizer, it seems there may be a problem with the fuel injectors, the light should be flashing bright while cranking. First check the injector supply voltage, one wire on each injector should have constant 12 volts, use a voltmeter if possible, the other wire on the connector goes to the computer (ECM) the computer determines injector duration by providing a ground signal of a frequency depending on engine speed to turn the injectors on and off. The crank sensor is one of the input signals the computer needs but not the only one, the computer determines when to let the ignition system fire the spark plugs, you said there are no codes and the crank sensor resistance seems ok.
It sounds like the computer is not turning the injectors on, the light should flash when cranking the engine. Hard to say what that may be without codes present.
It depends on where the crank sensor is located I think on this one it should be mounted on the front right near the crank pulley, you should see the wire going down to it, if not it's in the distributor, let me know which it is.d
It provides an rpm input signal to the computer.
Is the coil mounted externally or inside the distributor?
Ok, then the crank angle sensor is on the front of the engine, I'll send you some info on testing the distributor.
