my ecu chip is overloading and i need help figuring out the problem. it wont over with a fuse double the power though. i have no idea and it wont let my car start. does anyone know the problem.

 

I'm looking for help with this same problem...15A ecu fuse keeps popping and shutting off my car. can't drive 100 feet without it frying. HELP!! needed for both of us.

 

hardwire it LP im kidding, you probalby have a short to ground around the battery or the engine bay other wise are you using the correct ECU?

 

Already did that. My friend ran a new wire from the fuse all the way back to the main relay. Drove ok for about 20 mins and same thing started back happening. Now I don't know what to do next. Thought hard wiring it would fix it but *****....

 

A fuse blew so you put one that was double the value of the original one back in? And that fuse didn't blow?

 

i didn't leave it running long enough to see if it blew cuz i didn't want to mess up anything

 

Irony at its finest.

Do you have a meter?

 

no but i could possibly obtain one. i dont understand why after driving the car for so long it just starts overloading a fuse. ?

 

Because whatever it's powering is either going bad and drawing too much current or you've got a short somewhere.

Is the CEL on?

 

yup but it been on due to tha spedo sensor

 

Do not put a bigger fuse in there. Its going to cause more problems then what you have now. You need to figure what going on. I would check to make sure the vss plug is not the cause since you stated that its not working. Have both you guys tried a new ecu?

 

no. but when i unpluged the ecu and pluged it back in it crunk up and then i drove it around the block and it shut of again.

 

whats the best way to located a short or ground

 

sorry i don't have an answer but i'd like to hear what people have to say since i can't find a short on my 90 crx.

last time my ecu fuse kept blowing was because my o2 sensor wire got caught between some ish and crimped the wires exposing it to a ground.. i'd double check all your plugs in your engine bay and make sure everything is okay

 

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
i like this guy. thanks yo.

 

NEVER replace a fuse with a higher amperage rating fuse unless you want trouble. most honda ecu fuses are a mere 7.5A.
double check all your wiring to make sure that none are chafing against bare metal and causing the short to pop the fuse.
