A quick and dirty way to tell is to sniff around the connectors for the scent of burning electronic components.

The best way to tell is to remove it, unscrew the casing and check for burnt out capacitors and resistors.

Can I ask the reason you're wondering if the ecu is burnt out? I mean is the car not starting or running properly?

And I agree with Joshy, pulling it out and cracking it open is probably the best method.

Doesnt want to start up at all

As they said just pop it out by removing the kick panel from the passenger side, and unplug the ECU. check your wires too, also another reason why it might not start could be the main relay. Hope this helps

If you think it's ECU related and you haven't checked already, look at the ECU fuse before pulling the kickpanel apart.

What else is going on? It's summertime, so you might want to check the main relay.

More information man! Does the car crank but not turn over? Do you hear nothing but clicking sounds and have verified that your battery cables are snug? Feed us more info and we can better help you.

take your distributor cap off and have someone try and start the car. this will tell you if the timing belt has snapped or if the cam has broken. later.

timing belt is good so is the cam i triple checked

i have no idea why it doesn't want to turn on.. i had it running then turned it off to connect the alternator, power steering and air compressor, then i tried to start it again and nothing. next day i took the alternator, power steering and air compressor off and it still doesn't want to start

Wait, you have an air compressor?

Slowly walk though electrical parts you've disconected and recheck them.

could be the ignitor. remove it and have it tested.

a/c***** compressor

howd you check fuel? did you open the pressure line, crank and measure the distance that gas shot out?

an engine wont start on 25 psi.

[accordingly811]

did you check for compression/leak down test? if thats fine then it has to be something in the fuel or ignition system somewhere. check all your filters?
