I just recently had a 2000 model nissan maxima 3.0 twin cam given to me and for some reason I cant get it to crank. I have about 15 years experience in repair but I cant figure this one out. I put a new battery in the car and tried to crank it and it wouldnt crank. It was wrecked in the front bad enough for the air bags to deploy and I just thought since everything else in the car came on, it might crank. I replaced the starter after having it tested and they said it was bad. So I just put the new starter on it and it will not turn over by the key but if I jump the signal wire on the starter it will spin over. It never rolls the motor over though. Im confused as to what would cause this. I have checked the distance from the starter gear to the flywheel and it matches up. I just didnt know if maybe there was an inertia switch in the car or if the air bags being deployed in the wreck it was in may had shut the car down. Any answers or comments will be greatly appreciated. Thanks So Much For Helping.

Are the headlights and etc. Working? May want to check the fusible links to starter relay and other fuses. There is no inertia (fuel cut off) switch on the car, even if there was it would not stop it from cranking, it would just prevent it from starting up.

The headlights are working but it wont crank, if I jump the signal wire it rolls over and I have got the car cranked on ether. I think that the security system in the car is shuting the fuel pump as well as some electronics like the signal wire for the starter? Im not sure. I need to know if there is a way to disable the factory security system. Thanks so much for your help.

Again, a security system will not prevent cranking. It will only prevent the engine from starting up. This is most likely not the problem. Did you check your fuses and in line fuses? Can you hear the pump kick on when you first turn ignition key?

Yeah I can, I messed with for a little while yesterday and found out that I am gettting fuel to the fuel rail. I took the fpr off and fuel shot out the fuel rail when I turned the key on. I reatached the fuel pressure regulator and removed to fuel rail assembly from the manifold with the injectors still in place and tried cranking it to see if I was getting the noid signal for the injectors to pulse and of coarse, no pulse. The injectors are not spitting fuel out. I would think its highly unlikely for all 6 injectors to go out at one time so that pretty much is where im sitting. I have checked all my relays and fuses but still cant find anything wrong.

Ok, below are steps that troubleshoot and test everything on the fuel injectors circuits. if there is a fault with the injector's circuit, this will point it out.
