02 NISSAN ALTIMA, CRANK BUT WONT TURN OVER

02 NISSAN ALTIMA, CRANK BUT WONT TURN OVER
2002 NISSAN ALTIMA 2.5L, 147,000 MILES

This problem began with what appeared to be hesitation when I would first start it in the morning. This was noticed approx 1 month ago, at his point we had the car taken to the shop and they stated they put it on the tester and it came back with a Cylinder 3 miss-fire and we were told that it could be a number of things. At that time we replaced all spark plugs and wires, got an oil change, and all the fluid topped off. We were also told that it could be the cylinoid, not sure if i spelled that right, the piece that goes over the spark plug, which we have not replaced because again they were not sure if that was the issue. At first when I would start it up in the morning, it would start but made the noises as if it was going to stall out, but it didn't. This went on for the past few weeks, until last friday when I went to start it, you can hear it cranking to turn over, but it will not completely turn over. We took out the spark plugs to look at them, and 1 out of the 4 appears to be more burnt that the others. At this time other than the spark plugs, we took out the battery and had it tested and it is still good, we found the fuel pump and found that it was working. We also had the fuel pressure checked, and it came back that the fuel line is good and getting enough pressure. We though that maybe the crank ignition sensor could be bad so we replaced that and it still wont turn over.

Just another sum of what I hear: I turn the key to start it and it cranks but won't I guess fire up to turn completely over. Please if anyone can help me figure this out, we would greatly appreciate it. We can't get it moved to have it put on a tester again because of the financial part. Need to know what we are dealing with so we can get it fixed.

Thank You

RE: 02 NISSAN ALTIMA, CRANK BUT WONT TURN OVER
I guess that the first thing that we need to do is to get our mechanical wording figured out. The first one would be "Cranking" & "Turning Over." To a mechanic, those are the same thing. If you turn the key and the engine is being turned by the starter it is "Turning Over" or "Cranking." If it won't "Start" or "Fire," that is different. I think that you are telling us that it will turn over it just won't start? Correct?

The next one would be the "Solenoid." I am guessing that you mean the "Coil" if it goes over the spark plug? However, if your car has a coil over each plug it shouldn't have spark plug wires. But you said that you changed the wires? I need more information so that I know that I'm thinking in the proper direction. If it has wires it should have either remote coil packs or a distributor, either of which could be causing the problem.

Some other helpful information would be to know if the car was scanned with a Full Function Scanner or a Code Reader. What were all of the computer code NUMBERS that were found. (I am guessing that one was a P0303?) Any others? Has anyone checked to see if there is spark at the plugs?

Please get back to us so we can try to help you.

Sorry about my terminology and delayed time to get back with you. the sparks plugs were replaced, not the wires. yes they are getting spark. the mechanic we had check it out said that they ran some form of a test, i am guessinf a compter test. said that it came back with electronic throttle control problem. we were told to try and replace the electronic throttle body and we did that. it is still hesitating upon cranking. we did get it to start again, but it still isnt acting right. it also seems to not want to accelerate completely once i press on the gas pedal.

I really can't be of much help without complete & detailed information. If you brought your car to me I could perform the tests I needed & see the results to know what was wrong. But from here, you are my only contact with that vehicle. YOU have to provide ALL of the information for me. That may mean that you need to ask detailed information from your mechanic and write it down so you can get that information here accurately.

You said that they ran some form of test? I would also "Guess" that it was a computer test. But if you want accurate help I need to "Know" what that test was & the exact results. The computer will usually give Code Numbers, i.e. P0304. That is the type of information that would help us to help you. We can look up those code numbers to give us a better idea of what the problem is.

Another thing that could change the outcome is what type of Computer Scan Tool your mechanic is using. A "Code Reader" will give very limited information and usually can't access all of the car's systems. You want to have all systems scanned with a "Full Function Scanner." Record ALL of the code NUMBERS found, post those numbers here for review & have the computer cleared. If the problem persists any code numbers found now will likely relate to the problem.

If you still need help, please get back to us with the details.
