Recommendation for a good online manual for a 2002 Nissan Sentra

The fuses and relays cover all the windows, so the likely culprit is the door switch module.

1990 means searching wrecking yards for parts and Google online and check eBay.

I assume you checked the fuel pressure and it is normal.
Are the spark plugs getting spark when it fails to start ?
Are you getting injector pulse from the computer ?
Any trouble codes stored in the computer ?

Assuming that is a motor out of a 1999 Nissan Sentra this link should be a link to a Timing Belt Diagram. There is insufficient space to explain everything involved in removing the old one and all the parts that have to be pulled, if you need those directions I highly recommend you get the Haynes Repair Manual on a 1999 Nissan Sentra for those instructions.

The timing chain doesn't really have a maintenance period. They don't have a habit of breaking or stretching. Timing belts on some vehicles do have a recomended replacement period. Locate your local NTB, Firestone, or Sears for the maintenance schedule.

Have a mechanic check it for vacuum leaks!

Good luck and be careful!

According to Nissan PDFs on line, it seems pretty straight forward, although it seems pretty cramped around the headlight assemblies (go figure...) For the driver's side, it recommends removing the battery to make some room in the 2004 book (I would agree, after seeing mine). For all, it recommends at least removing the negative battery cable.
It states several times NOT TO TOUCH THE BULB. The grease from your fingers will reduce the life of the bulb, if not damage it immediately.

I pasted the links for the PDFs below- one for the 2002 and one for the 2004. I can't wait to tackle mine in -20 weather.
Oh yeah- you will have to re-program your radio after disconnecting the battery.
Update: (Dec. 29/07) I changed mine today, and it was very easy.
1. Remove battery for driver's side bulb.
2. Unplug electrical connection to bulb. There is a locking clip that you depress with your thumb to unlock the connection to the bulb casing.
3. Turn the locking collar counterclockwise to unlock, and remove.
4. Remove dead bulb.
5. After comparing the bulbs to make sure they match, holding the new bulb by the plastic casing at the rear, insert the new bulb making sure the notches seat into the seating tabs. Remember- DON'T TOUCH THE BULB!
6. Re-install the locking collar clockwise, and the electrical connection plug.
7. Re-install the battery for driver's side installation. (Might be a good time to clean the posts if they are corroded.)
8. Test the bulb. Re-set your clock and re-tune the radio.

UPDATE- with small enough hands, you do not have to disconnect the battery. This is a wasted step.
ANOTHER UPDATE: I just used these instructions, and they were very good, but for older Sentras it's a little different.


On a 1996 there is no "clicking" mechanism to turn counter clockwise. Instead there is a wire holder keeping the bulb in place. You have to remove the wire holder, and then you can pull out the bulb in its holder. On the holder there was a plastic piece marked "press here" which when pressed, allows you to pull the old bulb out of the holder.

Hope helped (remember rated this help).

lOOK BEHIND THE GLOVE COMPARTMENT. Compartmet is probabily plastic and all you have to do is push in real hard to get them past dash board.

Try the autozone.com website. Go there and register the car information and you'll have access to an online repair manual for the car. Hope this helped and best wishes.

good day Sir, try this link i hope this will help
