I mentioned before in other topics that i couldnt figure out how to read my codes. well i figured it out. there is a red push buttin wired to my ecu and i had to ground out the one wire. I grounded it out and when i started the car the ecu light was on, well i pushed the button then it blinked twice and then a really fast short blink. I have a 88-91 book but i have the p28 ecu and thats not the stock ecu. Can anyone hook me up with some trouble shoot codes? THANKS

it blinked 2 times slow then 1 fast does that mean both oxygen sensors are out?
and would that prevent my car from starting?

Each slow = 10
Each Fast = 1

 

now would that prevent my car from starting and where can i get one? does that mean my motor is fucked? i dont know anything about vtec motor its my first one.

Your motor is fine, it is just not getting a proper read from the VTEC circuit so a wire could be loose, the solinoid could be bad, etc etc.

 

well what does a solid light mean

 

solid light is code 0, means bad ECU

 

would i be able to hook up a pr4 to find out, its an ls ecu, would it make the car start

 

Any OBD-1 ECU will start the car, but if it isn't for the motor you will just throw more odd codes.

 

my car cranks over but wont start.. and can i put an h23 ecu in there? i got one laying around i can try.
