    check engine light does blink most time when engine is missing - i did inspect all plugs -it appears they have been replaced but i will say some time ago ( because of the gap ) - NO evidence of any coolent seepage or ( headgasket ) problem . i am ASE Master and it feels exactly like someone is removing one plug wire and at times 2 wires normally i can get 2 - 4 miles but at times 5 - 15 and or a rare ocassion it will just restore to running smooth ( on all 4 clys ) but never lasts lomg why will old sensors allow it to start easy and new OEM sensors cause it to almost not start ? i just might go install 4 mew plugs but dont believe it will fix this problem -- HELP me

    to ALL you stupid idiots _ that could not give me the correct advise - i did diag. & fix it myself . it did have one interm. coil . i guess i am STILL smarter than most ( maybe all ) i did grad # 1 way back in 1969 and knew all along no other person could be as smart as me . all you other should hang your heads in shame

Does the check engine light flash or is it on when the car misfires?? Bythe way, Nissan has a new program available for your ECM/computer for the long cranking condition. Check with your local NIssan dealer. Also spark plugs are rated for 105K, You have 110K on it. Check your plugs and make sure, that you use NGK if they need to be replaced. Also, look at your overflow bottle. If its down, top it off to FULL mark and monitor the level for few days. See if it goes down in like a week. I have seen some headgasket problems, where the coolant gets into the cylinders and drown the spark plug, causing a misfire. Let me know what you find. Lets get to the bottom of this and lets fix it.

    WOW, I don't think that there is a need for that kind of reply. People are trying to HELP YOU and its not that easy, when you can't actually look at the car your self to see what is going on and are trying to fix it over the computer.I can give you tips and pointers, but that doesn't mean that it will solve the problem. I was going to suggest to you to swap coils from one hole to another to see if the misfire moves to another cylinder, but you are TOO SMART for that. Anyways, NO MORE HELP FROM ME. EVER.

Where is the crank position sensor located on a 2000 Altima 2.4


I changed one on a 03 sentra and it was under the car by the exhaust entering the crank case. You can not miss it because it is the only object with a wire that is mounted to your engine block. Crank sensors will be close to the crank and cam sensors are close to the cam. I hope that this info helps.

There are so many sensors on cars now a days its hard to say, i can take a guess,you may need cam and crank sensors and the other sensors may be the oxygen sensors, this car is a 2005 this many sensors going bad at once is crazy, even with 100,000 miles on it, i would have a second reapair shop or dealer look at it,

Crank position sensor for 2003 Nissan Altima


a crank position sensor , sends a signal to pcm about crankshaft position signal, the sensor controls spark timing and firing order. the signal is also used for pcm to detect a missfire!! it also sends this info to ignition module, any mechanic can replace a crankshaft sensor!! call a auto parts store and see if you can get one, the cost should be a lot less.

SOME TIME MY CAR WILL TAKE 3-4 CRANKS TO START


Clean out the Idle Control valve. remove the air duct from the aircleaner system. spray directly into the valve opening. it is a small component with 2 small hoses . Sludge build up and oil deposits will dirty the valve. If that does not work you can remove it and spray directly into the 2 holes on the underside of the valve. Clean the air filter or replace it.if that is not it, then it is probably the EGR valve.

Crank shaft sensor


I have 10 years experience in a Nissan dealership and I know without a shadow of a doubt that the Crankshaft Position Sensor is NOT located next tp the crank pulley... it is rather at the other end of the engine near where the transmission bellhousing bolts to the engine block. It is on the side toward the firewall near the bottom. Even if you can get the vehicle on a lift and get under it, you can't really see it... It's more of a feel thing... There was a campaign (recall) on these engines to replace Crank Position and also Cam Postion sensors. Check with your dealer- the campaign might be open. You will need your VIN number when you call.

A common problem on this vehicle is failure of the Crankshaft Position (CKP) Sensor. Failure of the CKP Sensor will result in the vehicle not starting. The cost to repair the CKP Sensor is estimated at $29.13 for parts and $26.00 for labor.
