Will not start

Hi,

If you have a weak spark, I need you to check the wiring harness behind the power steering pump pulley for damage. Contact between the power steering pump pulley and the ECCS sub-harness may be short-circuiting the sub-harness to ground, preventing the crankshaft position sensor-REF signal from reaching the ECM.

I attached a pic below showing where to check. This has been an issue with these vehicles. If you have been moving things around to locate a water pump leak, this may have happened.

Let me know.

See pic below.

We checked it out there is no obvious damage. We traced it as far back as we could. On the left side of that cored we don’t know what is/where it leads.

Hello. It sounds like a few possibilities. I'm thinking the issue is probably in the coil. Weak sparks are usually caused by a failing ignition coil. I'm attaching some screenshots of AllDatas instructions on how to test the coil.

Another thing I'd do is to spray a decent amount of starting fluid into the intake and then crank it. If it fires then you have sparks.

If you haven't already, please check your fuses. A blown fuse can wreak havoc on a car. Fuse box information can be found in the owner's manual. The owner's manual is here: https://www.google.com/url?sa=t&source=web&rct=j&url=http://www.vadennissanservicecontracts.com/owners-manual/nissan/1996-Nissan-Maxima.pdf&ved=2ahUKEwjk687npYnwAhXcQTABHa23AG8QFjAAegQIAxAC&usg=AOvVaw3AtZE1eUB39NFkvFxZdA5u



Finally, I'd like to get a scan to see if there are any clues hidden there. There may be a terrible code that gives us a better clue.

Try this and let me know what you find. We'll go from there
