I have 2002 Trailblazer , which I did an engine swap . It currently won’t start . The key switch will not lock the steering wheel . I did start 3 time but only ran 30 to 40 second . I will crank over only when the starter is crossed over .Also when you turn the key switch to run position it with engage the starter solenoid All of the fuses are good I verified continuity with DVOM . I leaning towards Neitral Safety switch , Because I’m not getting signal voltage at the crank fuse . I would like to jumper the wires Neutral Saftey start switch but I’m uncertain on which wires I need to cross at the connector Thanks in advance for any help
