1993 Del Sol, engine turns over fine but won't start. No spark on spark plug. The check engine light does not come on when the ignition is turned on but the battery light does. Is there anyway to check if the ECM is getting power? After all, could be the bulb is burned out, I wouldn't have noticed.

Also, I checked the coil and found the primary resistance to be in spec, but the secondary resistance was infinite. I thought that was it but when I checked a new one at the parts store it did the same thing so I didn't replace it.

 

they have diagrams for the ecm connectors. we call it doing a power and ground test to the ecm. Most likely the problem is the main relay, they have problems all the time

 

http://www.pgmfi.org <-- you can find ECU diagrams/pinouts etc there... look for the wiki mirror.

 

Have you done any modifications to the vehicle? I have seen a ton of blown ECU fuses on tow-ins caused by tampering. Typically the part of the main relay that fails is the fuel pump control due to the high current. I would suspect power supply failure to the ECU.
