hey, does anybody know where I can find any type of protection for the computer (ecu) such as a relay or fuse? thanks

The ECU is behind the IGN and/or Room fuse I believe. How about you describe the problem you're having and we figure it out from there? It's probably not a fuse.

the car wasn't starting and I checked coils plugs and the fuel pump so I went on to check the fuel lines and those were fine and i got to the injectors but i noticed they weren't receiving a ground signal and wouldn't open which comes from the ecu i'm guessing that's my problem and why i'm checking the ecu.

So you're getting spark but not fuel injection?

Victor Arroyo

yes I took apart everything that is needed to remove the injectors and i checked the injectors on their own and they work but the ecu isnt sending a signal when cranking

Equivalent to crank sensor
. Its on the front of the engine to the right of the main pulley ...looks like a small silver cylinder. Is it plugged in?
Give us some history on the problem

Victor Arroyo

yes that is in i actually took it out to check it and plugged it back it in but the problem persists, i took off some parts to change a sensor because the would idle until warm and then shut off so i changed the water temp sensor and when everything was put back together it didn't even turn on so that when i started checking everything and i got to the injectors which seem to be the problem
