Re: 4AGZE Injectors Not Firing

OK that's cool

Someone mentioned early on to get a noid light to test the injectors
That was good advice

Re: 4AGZE Injectors Not Firing

when I heard that the clutch safety switch had been tampered with that told me that someone had been into the wiring when I changed the motor on my 88SC and 89SC I disconnected the harness at the ECU and feed it through the rear firewall and put it on top of the motor (after the rebuild I attached t...

Well looks like you narrowed down the problem

There are all kinds of ways to do a conversion like yours

Re: 4AGZE Injectors Not Firing

If the resistor pack was not giving the full amount of voltage, would this affect all the injectors? yes should be 9v to 14 v according to the book the diagram I posted above shows the switch for the clutch the below shows the pin out for the ECU https://i.imgur.com/AWiYr3j.jpg?1 I will check my car...

Re: 4AGZE Injectors Not Firing

I think an important question is does you car turn over when you try to start it (does the starter motor spin)

Re: 4AGZE Injectors Not Firing

thanks Jondee as far as I know all MR2's have a switch on the clutch my 85 had it as well as my 88,89 SC MR2's have it we usually save the wiring stuff until after we do the basic check for example unplugging the connector eliminates the injector then you test for power and ground after that you unp...

I just went out to my 88 5agze and the car wont even turn over without pushing the clutch in there is a clutch interlock switch I mentioned it because you said you just finished a rebuild (which means its been down for awhile) and sometimes people for get its a real pain since you have to jump in th...

Re: 4AGZE Injectors Not Firing

Yes the 12v on that one side is a big problem When you unplug the injector that reads 12v on both sides is a easy step And might eliminate one item (the injector) Or a short at the injector plug Now here is the problem Because one transistor inside the ecu controls two injectors it is possible havin...

Re: 4AGZE Injectors Not Firing

Both,
there are several grounds on the GZE I can think of one on the intake, another on the removable panel near the coil



Also remember you have to push the clutch in when you try to start it
And you should get a slight tach bounce

Good luck

Re: 4AGZE Injectors Not Firing

Cranking the engine means its turning over 12v resides on one side of the injector and the ecu applies a signal low/ground to the other side and that's what fires the injector Inside the ecu they use two transistors to switch the low/ground to the injector Recheck check Check grounds then retest David
