DEAD ECU ????

[Dasithkg]

hi everybody..

does anybody know how to check if the ECU is dead?

think i fried mine....... it doesnt give any OBD codes....
service manual says NO CODE = ECU DEAD

but all the other electrical stuff is working... lights, fuel pump, Gauges, etc .......... just cant start... check engine light is on, so checked for OBD codes.. none comes up

any ideas?

cheers

Stock?
Mine wouldn't start once Coz simply a wire had shorted to power the ecu. Check over all ur power wires to ecu and see if anything has shorted. If not im outa idea Coz that all I've experienced with them

when my daughters car had the ecu die. it would crank and had all the lights but just didnt start.

she drove into a friends drive way stayed about five minutes and went to leave....dead ecu

BUT I can say there is a difference in what your symptoms are.......her fuel pump didn't work as there was no output from the ecu to the main relay

Ive had the ecu die on me twice now
Take it out from under the kick panel
open it up take the case off...see if it smells or looks burnt
could be the caps

A quick way to check the ECU is using the boost pressure organe light bar on the dash. With the ignition on the light should come on to half way, if there is no lights the ECU is dead namely the caps are gone.

you have to open it up and have alook if the capacitors are any good , check VFAQ there is a guide on there

An average sense of smell works pretty well... Stick the sniffer near the ECU and if there is an electrical burnt/acrid smell... theres a pretty good chance the ECU has suffered the dreaded leaking capacitors. Inspecting the ECU board will confirm this.
