    Who said it was the regulator? Why are you chasing fuel related problems? There must be a reason why you are going this direction. Does the red KEY light (looks like a car with a key inside it) come on when you try to start the car? If so, your ignition key isn't registered, and it will never start. Let's start with the basics before we go after the bizarre.

What is the symptom? do u have a trouble code for the knock sensor? It is a part that is seldom replaced because of the way it works it has a very low failure rate. The sensor is always screwed into the water jacket of the eng block, look up a picture of the part at an on-line parts store like, then you will see what and where is is.

My 2002 infiniti q45 turned off while sitting at a traffic light. Tried to start itbut in won't start. Diagnosed it and It showed cam shaft position sensor circuit malfunction. .code P0340...I replaced...

Did you check your fuel filter? Did you have a shop install the sensors? If they are not positioned in correctly, it won't work. Have you had your fuel pump checked as well? That's in your fuel tank. With this high end car, there may be a reset code as well.

Why does my 1999 Infiniti Q45 starts then dies after 5 seconds?

If the regulator has a vacuum line to the back of it ,check that the line is operational. A good fuel flow before the pump indicates that the pump is moving volume but when a restriction is added ( regulator ) it may be passing the fuel back past the gears in the pump. have a fuel pressure test done on the fuel manifold . If it is excessive then there is a problem in the regulator. However if it is low then the problem may be in the pump.

Security on. car wont crank. can trun key wont

verify that you have a fully charge battery and that you have the same amount of voltage at the battery as at the starter when the key is turned to the start position. If not repair fault at positive cable either at battery or at starter. If voltage checks good. Use a remote starter and turn key to the on position and try to crank over engine with remote starter. if engine cranks over. You have a defective starter solenoid and starter must be replaced.

I have a 94 Q45 with fuel pump problems , I installed anew fuel pump now have good pressure,but car still wont you have any suggestion on what else it could be

A bad fuel pressure regulator (underhood on the fuel rail) could cause it. If the FPR is bad, the rail won't pressurize enough to get the proper fuel in there to start and run the car.
