crank position sensor

bad egr value

I believe its the right, but if I am not mistaking, it does not actually matter.

At the beginning you say lots of fire but then no fire and you replaced rotor and cap no fire? Check the wiring to the dist. and inside for anything loose that could make contact and then loose it. No I do not think its your key system. Also fix the knock sensor, it has to do with the fuel system. Hope this is helpful Mike

Shift lock is just a safety feature, so you have your foot on the brake, when you put it in gear. It has nothing to do with starting the car. Intermittent starting problems can be a few different things. Ignition switch, park/neutral safety switch, wiring, and corrosion. If it clicks when trying to start, it cold be loose/corroded battery cables or a bad battery.

have a scanner do this as it will reprogram the CPU properly

You'll need a creeper to confirm this, but I believe that it is located on the inside surface of the passenger-side outer frame rail. Hope this helps.

Check with a mechanic before running your engine - sounds like you are doing some damage and book you are using is incorrect.

Hi Marty,here's a link to your P0300 code.

it might just pull out

Are you in a tight spot and can't drill?

check the fuse for the cigerette lighter,most of the time that is the problem

Hi M, Turn the knob of your test meter to mili voltage. Remove the sensors one at a time and connect the cables to your meter. Pass a flat metal screw driver above (about a millimeter or closer, but not touching) and observe the meter. The meter will display a small voltage if it is working. The rotor mounted onto each wheel, as it turns generates an electrical charge. Just before lock up the charge drops, signaling the management system to momentarily release that brake. Regards John

Question edited for clarity and make a sentence. Question moved to model category. Normally you tighten the hub nut whilst turning the wheel until it locks solid, then you back off a quarter turn and it should turn freely. https://www.google.com/search?q=Nissan+Frontier.replace+front+wheel+bearings ..

The restarts? That sounds like the classic symptoms of a failing fuel pump
