Glad to be on here! Names Rob! I buy and sell Hondas mostly early to late 90's models buy them broken sell them fixed and ready but like everyone else I still run into some technical difficulties.

On the car I'm trying to fix it will not start until the D4 light comes on and go's off I replaced the igniter but it's still doing it doe's anyone know if I need to replace the ECU or will there be some burnt resisters inside or what's causing this?

Ok changed out the ECU and the D4 is still coming on before cranking I've had more honda's then I can count and I do not ever remember the D4 coming up when you turn the key to starting position and funny thing is once I get it to start it's fine for the rest of the day?? This prob. Has really got me stressed I know someone on here has the info what's the deal with this pos???
