I need help ASAP. I just followed the directions on the sticky on checking for the ECU codes. After I got the codes: 0103 and 0402.. I took out my keys.. and inserted into the ignition and press the clutch.. trying to start the car.. but my car WONT START. It makes the tet..tet..tet..tet sounds.. all the dash lights are lit up.. but car wont start.. PLEASE HELP!!

 

This is just an idiot check here, but did you turn the screw on the ECU back to its original position? If you didn't that would be your problem.

 

I'm pretty sure I did... But I will definitely double check.. anything else that may be the cause?

 

after you turn the screw to check it, you must repeat the process again to reset the ecu or else it will stay in diagnosis mode or something like that. just go back and turn the screw as if you are checking the light and when you start the car, it will recet the ecu

 

also you have to leave the key in ACC to do all this

 

You mean I have to leave the key on the "ON" position. Anyways... I am pretty sure I put it back to the regular mode.. not the ECU mode.. cuz the light is solid now.. not blinking mode ECU codes. Anyways... the second time I tried to put it back to the original mode.. I got another code 0505.. I dont know what to do now..PLEASE HELP!!!!!

 

if i'm not mistaken 0505 is a normal ECU code. i'll tell you what happens when you don't turn the screw fully counterclockwise after you diagnose it. i know because it happened to me! lol. all that happens is you get hard starting because the engine bipasses the coolant sensor thinking that the engine is always warm therefore running lean and stalling shortly after startup. also, your idle will be at around 400rpm and will make the headlights go dim at a stop. this is all because the engine isn't turning the alternator with enough speed. if you're cranking the engine and there is absolutely no fire up, my next guess would be in the fuel system. i've had my fuel pump seize up (from bad fuel). also rule out the ignition system and make sure your battery is properly charged. anybody else have any ideas?

 

Anyone else wants to shed some light? Any Help would be greatly appreciated!!!

if the screw is in the normal position it sounds like your battery is drained... check if the headlights are somewhat dim.
