I have a crx b16a1 and one Day I Was going to start the car and doesnt start. The shymptoms are The car crank and no start, engine light on all the time, the ecu doesnt blink Nothing, the fuel pump doesnt prime and the Shop that i Take the car says that it doesnt have spark. I already chance main relay and its the same.

what could the problem be?

 

If the check engine light is constantly on but there are no codes, then the ECU is most likely the problem.

 

Sounds like maybe just a bad ground.

 

Just to be clear, you took the car to a shop and they have no idea? This would be basic troubleshooting for any shop.

 

yeah dont understand some mechanics, if a have right space i would learn how to work in my car

 

i Just try one ecu and the problems are the same, maybe the problems are in the wires

 

to be sppecific, try the grounds on the thermostat housing
