I have a 91 crx with a obd1 conversion. Ive checked the ecu, main relay, and ignition harness in other cars. I changed out the fuse box for one from the junk jard and two different dizzys from autozone. when i turn the key to the on possison my fuel pump turns on and i can crank the car. Any ideas on what it could be?

 

Check grounds especially the ones on the thermostat housing.
Troubleshoot the distributor.

 

ive unbolted and cleaned the thermostat ground. ive also rechecked my valve cover and tranny ground. i see nothing wrong with my third new dizzy but one of my friends is bringing over a multimeter.

 

Turns out I'm gonna rewire my engine harness ***** weak.
