I have a rb20 was running good, but had a high idle problem replaced the tps with a new q45 and wired it in, but know it wont start up, no codes fuel pump primes spark at all 6 will not start with starting fuel,injectors are getting battery voltage at both ends, Is this my problem? i looked up information and it says one wire is battery voltage and the other is grounded from the ecu?

did anyone else have this problem?
