I have a 00 si and the other day my vtec stopped working due to low voltage on the tps sensor. When i got to testing it i accidently grounded the positive wire and it made a clicking noise around my fuel rail and now it will not start. Its not getting fuel and the main relay isnt clicking but i replaced the relay and still doesnt work. Fuses are good and its slightly fires over every once and a while and with 30 mins of trying i can get it to start but its nearly impossible to keep it running. Did i fry my ecu ?

Oh forgot to mention the cel lights on but my scantool will not pick it up.

volt meter on the red/black wire will tell you if your ECU is still putting out the 5V required.
If it's not, you likely popped either the underhood ECU fuse, or the ECU itself.

=( i checked both pgm-fi fuses under the hood and the drivers side panel and they are noth good. sooo.. thats bad news.

sry it took so long. It came out at 3.5 volts ? My battery was dead also and i didnt get a great ground ... So now what

Yup i swapped out ecu that was the problem. Im getting tps high voltage now ? I wanna be sure i put the wires back in the connector right. Looking at the top of the connector from left to right the wires go green red yellow? Is that the correct order.
