my mom's car (sedan auto '92) was working fine yesterday and today it won't start

-no fire, no gas
-CEL light never turn off, but there is no flashing error code when bypassing the 2 sockets, it just always stays on (and I've checked cel code before)
-fuel pump works when manually powered with 12v but is not powered when starting normally
-main relay is fine

is my mom's ecu fired?

 

or is there a simple way to check if an ecu has gone bad?

 

From what I've known, Code 0 = fucked ECU.

 

im haveing the same problem i changed the dis, cap, rotor, plugs, wires, ecu, and ing fuse.... STILL NO SPARK i haven't checked my main relay yet but im going to tommrow but if i can get it running then that motor is comming out

 

chances of the ECU "frying" is un-likely

 

Try another ECU and see if it works.. But check all fuses first.

 

does a '93 DX stand. ECU work in a '92 LX auto ?

no, well maybe to start it...

 

r u sure u jumped the ecu the right way

 

The ECU could very well be fried. Ive had this happen to me, the thing is that for what ever reason that side of the car is prone to leak water right where the ecu is. Thats how mine got fried and you can open the ecu up and look at it and see if it looks fried or you can smell it. Thats how i figured mine was fried it kinda smells like a blown speaker

 

yes it will

 

it was the ECU!

so as someone said,
check engine code 0 = fried ecu

 

oh ya and to answer the question the manual ecu would work

 

yes the manual ECU will work, But you would get a CEL

 

ya im seeing if mines fried 2, the check engine light stays on, fuel pump doesnt kick in and ecu doesnt blink
