The Maxima is hard to start at times, and when it finally does start it acts like it is missing on one or two cylinders for a couple seconds and then smooths out
All my senors going bad crank cam O2 and many more
my car start rigth over but whem work for while o get hot dont start I have to wait for while to start
won't start
knock sensor location
Turn the key engine does not start all electrical works battery is good. Found this feed and all of the smptoms match up i will replace the sensor hopefully it fixes the problem
Had oil leak had to replace it and sensor alternator
problem getting car inspected
98 Maxima cranks but won't start...have replaced camshaft sensor and crankshaft pos sensor, fuel filter, fuel pump, cleaned IAC and EGR (since I was in there) and new battery, new starter...checked MAF...checks good at the sensor...when I am trying to start it, cranking the engine, the rpm gauge does not move at all.
I check with the torque app and no rpm registers in it either.
any suggestions for next steps?

I did also pull and visually check the ECM and there are no apparent bad spots or components on either side of the board.
how can i check the crank sensor inputs to the ecm?
where can i find a diagram for the ecm connector so that i can ohm the wires from the MAF and ckps-pos and ckps - ref?
thank you in advance for helping!
Kids it's a 2005 Nissan Maxima and then when I go uphill it makes noise when I go fast nose goes away when I drive slow loris when I start in the morning no worries then run fast I was going to win
