what are the signs of fried ecu? can anyone give me some first hand diagnosis of what a fried ecu does? thanx

 

well just a guess but if something actually did "fry" then you would prolly smell it... some ecus have a little "light" on the outside that might indicate the status of the ecu... otherwise you might see some of the indicator lights on the dash not turn on or not operate correctly...

 

No Start, Bogus codes, odd symptoms. Why are you asking, whats the Problem?

 

By Fried i don't think he means it literaly. . But in that case Add Smoke to the list.

 

Yeah smoke would be a good indicator too haha

 

lol, yes, not working. not accualy on fire . im getting power but when i go to turn on the car i get nothing. no indicater lights,no radio, no heater, ect. ive got battery power for sure because the headlights come on, the dome light comes on, the door dinger is dinging, ect.

 

So your symptom is the ignition is swithced on but you don't get any accerories, and the vehicle is in a NCNS.

 

yes

 

Im 99.9% sure its not an ECU issue. Your probably looking main fuse or starter relay. Its probably one of those black square fuses/circuit breakers/relays in your under hood fuse box

 

you check your fuses at all? start off simple...

 

ok I don't think its your Ecm, possible a Fuesible link. I don't have the Ability to check Alldata right now, but thats what i would check first, they should be in your fuse box, they are the things with the translucent plastic cap. You should be able to see if they are broken or not. Also you can check the fuses with a test light, if you want to make a custom test ligt, you need a ligt for use with 12v, typicaly one that you can Unbend the contacts, and about 6ft of wire and a paper clip. Cut the wire so that 12 inches are left on one side and about 5 ft on the other, strip all end of the wire (remove about 1 inch of the insulation). Tie or wrap one end of the 5 length aroun one contact and the other side you ground. Do the same thing with the Smaller length but don't ground it, instead tie the other end to your paper clip and unbend it so you have a point. Electriclal tape would be a good sugestion, but isn't required. If you touch the paper clip to a "HOT" (B+) line the light will illuminate. So you check the fuses by Swithcing the ignition on and making sure both sides of the fuse make the lamp light up. If niether side has b+ then it isn't being use at that time.

 

ill give it try thanks guys.

 

i got it figured out two fuses gone lol im a retard. thanx for all the imput guys. ecu isnt gone ya! i didnt even think to look at the under hood ones doouughhh!!.
