ok i have a 97 teg ls vtec obd2 p72 ecu and its been running like a champ untill today the fuse under the hood blew and everytime i put a new 1 it just blows what could this be. ive open my ecu no burnt smell or damage i dont know what it could be help please

 

Have someone look at the harness and see if there is short some where. Which fuse is blowing out?

 

the 15a under the hood thats for the ecu it first happend when i hit vtec around 7k then i put a new fuse in and drove home and now it wont start again and the fuse keeps blowing

 

Check the fuse connector, see if there are any burn spots.

 

i messed with the injector wires moving them around and put a new fuse in and it started up then as it was running i barley pulled on the injector wires and it blew the fuse so i am thinking there might be a rip in one of the wires that causeing this so ima go check tonight and ill get back to you . but do you think that would cause it

 

What is the fuse number?

Power wires on the injectors are grounding out. This is normally the cause for the FI/ECM fuse to pop. Essentially, look at all your YEL/BLK wires for shorts.
