ok, so i have a 1990 crx that i been working on that is having some problems. i had the head on it rebuild and resurfaced, put everything back together, car started up. 2 days later. car wont start anymore. so i change to dissy cap and rotor, still nothing, i change the ign. coil. still nothing. car has no spark. so then i check the fuel, and there is no fuel pressure either. whats going on. im not real familiar with OBD-0. someone told me that the light on the ecu should flash when the ignition is turned on, but its not doing anything. any advice?

 

im first,


ECU fuse is blown, garuntee it... or the ecu itself went bad.

 

Well I guess I'm second...

Is the light blinking at all? is it soild?

I think untitled gets the cookie for this question. +1

 

i checked all the fuses in the engine compartment, and there all good. then i tried changing the ecu with another. i think the car had a pm6 or something like that, and i tried a pr4. its a crx si. and there was still no light, no blinking light, no solid light, nothing. so i dunno. where would the ecu fuse be located on this car?

 

the 15amp should be blown...

if not check your main realy, swap it out with one that works. The main relay controls fuel and spark power.

 

where is the main relay? what does it look like?

 

its under the driver side dash...

seriously youll get way more info faster if you just run a quick search, youll get photos and all info how to fix it.

You can resolder if its broke or cracked, it will be in a rectangle box and bolted to the car by one 10mm nut, its a bitch to get too, so after you get to it, leave it unbolted but tucked away.

 

alright. thanks for the help. hope this is the problem.

 

with cars ive came up with this saying

Hope for the best, Expect the worst.

Good Luck
