that would be the engine front , you sure it's a Rattle ? if so ? it will be your Camshaft bearing noise, is it a 2.5 L 4 cylinders ?or 3.5 L V 6 !! . if it's 2.5 L , your Camshaft bearings are starving for oil , so I suggest you check them both intake and exhaust cams and see also if the valve lifters or cam bearings are in bad shape , worn out ? check also both cams journals and drive journals to lifters ( contact operation ) if there is a suspicious gaps between them that also can cause a rattle sound .

Your car is probably in the limp mode meaning it won't allow you to rev the engine with it in gear. I suspect something majorly is wrong with your tranny. Limp modes are put into effect when you car senses trouble so it may still be fixable without too any $$$. When was the last time you serviced the transmission ( oil and filter change?)

Double check the battery positive connection wiring carefully as it commonly has connection problems when the battery is changed.

Bad SWITCH,

Call him back and have it programmed again, if that fails you need the dealer to look into this.

Since it doesn't have one. Have the codes read.

Hi Daniel there is an engine management fault that has put the car in whats known as (Limp Home Mode) you will need to get it diagnosed to find out exactly. Regards Jim...

Bad head gasket, most likely.

replace the crank sensor if it is a 2.5 ltr or cam sensor if it is a 3.5 ltr

There could be a number of probable causes. First I would check to see if it starts in neutral. I'm assuming this is an automatic transmission. If it does, the problem could be anything from a bad connection coming off the neutral safety switch to the harness , the needs of a slight adjustment of the switch which is located on the transmission where the shifter shaft is located. there are screws or very small bolts that can be loostened to allow you to roll the switch forward or backwards (Note, you only move it a fraction when you make the adjustment and try it again). There is also a relay ( think which is located on the right hand side of the car mounted on the inner fender. Usually the cover for the relay box will be labeled showing you which relay it is. The label may also be located on the inside of the box cover. If you are able to locate the relay, the top of the relay will have a picture showing one part one the top which goes accross the relay cover that has a curly section whic connects the two points. One of those teerminals which the relay pins or spade connectors coming out of the bottom the the relay will get a signal from the ignition switch ig thee circuit is completed when the key is turned to the start postiton. Using a test light is the easiest way to check it. Using the test light, check the two terminals to see if tth test light goes on This is before you turn the key. (reason being some of the nissans used grounds to make and break the circuits to the relays to make them energize. If one of the terminals is hot, it uses a ground to operate the relay when the ignition switch is turned to the start position. If it uses a ground, Ground the end of your test lead to a positive power supply which is hot all the time, like the battery. When you turn the switch, the side thich is opposite to the one you just tested, should light up.. Now. Checking the other terminals opposite eachother, one should light your test light the other should be dead. If you don't get the test light to light to light up on either terminal (female part), you have a problem with a power supply going to the relay to complete the circuit to the starter.Sometimes if you are lucky, you may have another relay in the box which is identical to the starter relay on color and size. You can swap these out for testing rather than going through all the the above tests I described with the test light. . Just swap them out, turn the key and if the starter turns, th's your problem. If the testing I described above with the test light gives negative results, one, which requires you to turn thr switch would indicate the problem is between the relay box and the ginition switch. And the other I have already told you about.Don't rule out the ignition switch, you would have to take the column cover off if I'm not mistaken to access the connector. I don't have a schmatic in front of me, so I can't tell you that color wirewould come off the switch to test at the harness connector with a test light or digital volt/ohm meter. You can get a schmatic off the Internet. I hope I have given you some direction to go gin and how to go about checking things. The neutral safety switch can be checked with a digital volt ohm meter. There should be three pins in the connector. If, I am not mistaken. Ine is a common, usually the center pin. The outer pins are the ones which complete the circuit then it is in park and the other in neutral.If you have the connector disconnected and can test the switch as I have described, you have to have a friend move the fear selector slowly tp Park and then to neutral. If it fails either test, then loosten the bolts or screws enough to where you can rock the switch, usually towards the back of the car. Remember "JUST A SMALL AMOUNT and then repeat the test. If it still fails, you have a bad neutral dafety switch.Again, I hope I might have shed some light on the subject.
