Hey guys,

I did some searching around, and didn't find anything related to my problem, so I was hoping a few of you in the RB world would have a solution for me.

I just recently did my swap and have come to these problems:

If you hook up the starter with posative on the left post, and negative on the right post, then try and start the car, the fuel pump primes, ECU turns on, and everything looks normal, but the starter does nothing, not even click. Then if you change the order of the battery wires, (Posative Wire, on the Negative Terminal) the starter will continuely crank without the key even in the ignition.

If anyone has any sort of an answer, it would be great, because I am starting to get really burnt out on the project....

P.S - Takara Motors did the wiring on the upper wiring harness, but they nev er did the wiring on the lower harness when I sent it to them.

was your car converted from auto to manual? Put back the wiring to where everything works normall----priming fuel pump and all. Then a signal from the starter to a power source----- to test it out. If it works, then connect that sginal to your ignition switch.

OK guys i figured out the starter problem bad wiring, but the car still wont start it has a healthy crank getting spark, fuel and it has good compresion. i turn the key fuel pump prime and the ecu comes one (via red light) try to start it and it just cranks away....

Any ideas

Thanks Justin
