My 93 civic can not start. I checked to see if theres spark and fuel. Yes it has both. I tried jumping the ECU and i got the code 6,10,20. I thought maybe the ECU may have problems. So i tried to reset it by unplugging the battery. And hooking the battery back up. Still no start. I tried to jump the ECU again and this time around the CEL is solid and doesnt flash at all. Not main relay for sure because I have 5 spare ones and i tried it and still no start. The Fuel Pump primes whenever i turn the key to on.

I check to make sure the ECU is getting enough ground because I had an ECU ground problem before. And the mechanic told me that the ECU was having bad grounds. I can think of 3 places where the ECU uses as ground. The main one is on top of the T Stat, second one is where the chassis is hook up to the tranny, last is where ground is on top of the power steering pump. I even went and clean the ground to get a better contact. But still no start. So is it true that if there is no problem detected by the ECU the CEL would stay solid when i jump it?

So what do you think the problem maybe. I even changed the dizzy and injectors with a good one and still no start. Maybe the spark plug wires?

 

anyone?
