I have a similar issue, with an 03 spec v, and I feel like I have tried everything. I just changed all coil packs about one month ago. I googled different combinations of basically: crankshaft sensor disconnect start and found a rare few forum topics of people with different cars not being able to crank unless the sensor was disconnected, and the typical response was that there might be something wrong with the camshaft not just the sensor! The car does seem to have compression as well, but I'm about to check the codes again not that I think they just magically appeared , but I'll also check the security light. The car was fine for 2 days!! Anyone care to give me their 2 cents worth? Then when I gave up and called a tow to Nissan I decided to give it one more go and she magically started up. Start by blowing into the connector, then wrap the shop towel around the tip of the small flat head screw driver to clean what is left. The coil pack that was on the cylinder that had the sparkplug well fill with oil is the one that isn't getting spark so I know it needs to be changed. This engines timing is still perfect but the ecu recognizes this condition and does not allow the engine to spark.
I have good spark out of the coil, nothing out of the distributor. They are two different situations. I'm avoiding taking it to a mechanic and especially the dealership, maybe I'm just stubborn haha. Everytime i start it its hesitant. Autozone said the battery was fine even though there seemed to be a slight drain on it and they refused to replace it.
Check engine light came on. Today I tested to see if I had spark, which I tested cylinders 1,2 and 3 all had no spark and guessed the 4th wouldn't have spark. Not to mention that I don't really have much faith in dealerships for trouble shooting stuff like this as many of the posts in theses forums show. This is really becoming a inconvenience. This morning when I got ready to go to work the check engine is on again.
I'll return later this week after this commercial break. Then suspect bad fuse or pump. It would restart but not run very well. I Dont know what else to, any advise? Not sure why you would replace the Crankshaft position sensor unless your vehicle is stalling on the road or at stop lights. It Cranks but wont start as the injectors wont open. After returning from the Panel Beater the car refuses to start.
If continuity exists, go to next step. So I checked the fuel pump and it works fine so then I checked for spark and found none. Thanks for any advice in advance folks!!! Going on about a year now no issues. I'll have to check the security light as well, since I haven't checked that out yet. Cant think of anything else at the moment. And I replaced the battery a few months before this problem. Bought car from guy who thought timing chain was gone.
Before I got her to start I took out the plugs and let the cylinders dry. Nobody seems to know how to fix this issue. It's important to remember that you need to use a spark tester. Ordered a battery charger since the 73 nova doesn't have a great battery either, but it should be rechargeable as well, just good to have. I had the power transistor tested at the auto parts store and it is good.
Then the power circuit has a problem. Is timing chain only for the valve timing? Would that cause no spark? We got all back together and went to fire it up and no spark we double checked every thing. Okay, so I know you said not to reply with the basic stuff, but. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. My actual problem with no spark was that the cam and crank were too far out of sync due to a worn timing chain and the ecu over rides the request for the signal to send spark to the plugs. I was pretty focused on the sound of my battery draining haha. Make sure the coils snap down on each plug and reconnect all wiring.
Air isn't the issue, spark probably isn't the issue. The warranty should not be limited to the original owner. You will have to tow the vehicle to the shop; it's dead in the water. Any help would be much appreciated. You have rotation from the starter. I would also need more specifics as to which engine you have so I might assist you in where the location of the sensor is. I am also going to see if the coils are getting power with the key on.
Usa an appropriate tool to back probe or pierce the wire to get to the Voltage within the wire. No spark on any other cylinders. If no spark on all coils, Check Timing. The only difference with mine, is that I get an initial spark trigger, and then it cuts out. Best, Ken Computer problem 2002 Nissan Altima 4 cyl Two Wheel Drive Automatic My car was running fine then one day it would not start. I notices in the trunk a keyless entry box that was not there when I took it to Nissan they said they didn't put it there well I know I didn't. It cranks and starts after getting a bit and I think holding down or pumping gas pedal helps it start.
If I wait a moment and stop before trying again, then it works. This is normally done when certain conditions of the engine are met and it is advanced for better performance. Also see if the injectors have pulse letting you know the problem may be on the amplification side of the ignition system. I called Nissan and they told me it's electrical Duh I already said that then they said well have it towed here and it will be 100. If the camshaft position sensor or circuit is faulty most engines will start. It turned off after 3 days or so.
