Nissan Repair Questions? Ask a Mechanic for Answers ASAP
I'd say its likely that there's a fault with the distributor cap or the leads to cyls 1 & 4
So I'd begin by removing the distributor cap and check inside for cracks and track damage
also check the condition of the rotor arm for cracks and burned contacts, there should also be a little carbon brush in the cap that pushes onto the rotor arm
Check the resistance of the spark plug leads ( 13-15Kohm / metre) and replace if any doubt or high resistance - Also replace the spark plugs if any of them fail this checklist:http://www.ngksparkplugs.com/tech_support/spark_plugs/faqs/faqread.asp
thanks for letting me know as 2000 was the transition year from a dizzy to coils
in that case I'd next try spraying some water on the coil packs 1 at a time with the engine running. It is possible the coil is faulty and causing the misfire. If you see sparks arcing with the water, then replace the coil.
Also have you tried doing a compression test across all cylinders?
as they should all be within 10-15 psi of each other
as you have no spark then check that there's power to the coil pack (at the other end of the plug lead) using a meter. If there’s 12V at the pack with the ignition on but no spark then check the ECU power supply (fuse and relay) and also the connections to the crankshaft speed sensor.
do you still need help?

sorry I don't have that information
I'll opt out to open this up to others
Hello my name is ***** ***** thank you for your question.
Do you know if you have any codes stored? Also when you turn the key to the ON position, is the Security light on solid?
Does the engine turn over but not start? or it doesn't even turn over?
Did you change the battery recently?
I saw you said that you have spark plugs getting soaked with fuel. Did you get gas recently?
That could be due to bad gas. Has the car been sitting for a while?
Do you have any codes? Did you happen to have a P0505 code before all this?
Do you happen to have a noid light to check injector pulse?
are you a shop?
Do you have a noid light to check to see if you are getting injector pulse or a constant signal for the injector to stay open?
This sounds like a Ecm issue.
The cam sensor you unplugged, that is the one on the top part of the front timing cover right?
When you unplug that and you get injector pulse, that is a sign that the engine jumped time
So that would explain why it's loading up and why you don't have spark or injector pulse. You are going to need to check the mechanical timing. If more than 2 teeth off, you could have valve damage.
Did you disable the fuel system after you did the timing chain work? The reason I am asking is cause if you do timing chain work, and don't, when you go to start it, the chain tensioner is not primed yet and it can jump time.
You disable the fuel system and turn the engine over like you were trying to start it. but it won't start cause the fuel is disabled. By doing this your allowing the tensioner to build oil pressure
I can give that to you later when I get home if you can wait?
Ok. I will share it with you later then.
Talk to you then
That is the timing mark locations
ok.. Talk to you tomorrow.
