Hey buddies, since a few weeks ago my car doesnt start when hot, it needs a little cooldown before start again. Somebody told me about the main relay and I exhange it and it doesnt work. I try starting it using a gas wetted cloth and it starts well. I want to test the resistor module that feed the injectors but I Dont have a clue about where to find it ir how it looks. Any advice about where to find it?

This goes to the General Forum where you shall get help...I moved you to here...

Thank You for posting..

 

Look on each injector's wiring plug. One wire on each, is all the same color (red/black?). THAT wire should have battery voltage when the key is turned ON (don't start the engine). That's a crude first check of injector circuits.

All my Hondas were more recent & didn't have resistor boxes, so I hope someone chimes in with more checks.

 

I'd suggest you cut to the chase;
Use a long screw driver as a stethoscope and listen for the injectors CLICKING when he engine is being cranked.
Turn on the key, stand on your head behind the drivers seat, check for flash code from the ECU.
It might be worthwhile to check the temp sensor.
