Are all the cylinders getting fuel and spark?

punxva · 01-09-2010, 10:41 PM

hmm so your saying that you have both fuel and spark? and good compression on the cylinders? This is strange, so when you unplug the injectors you hear a noticeable difference on all 4 cylinders? Or does your car just sound like it's on 3, because then that could be something totally different.

every cylinder has to have spark and air mixture but i doubt your getting fuel in #4 Im sure its your fuel injector... im positive

happened to me

240goslide · 01-10-2010, 08:59 AM

Why did you make two threads?

ellococt · 01-10-2010, 10:47 AM

I'm confused if it's getting fuel and spark why is #4 your problem? Pull your injector connectors one by one and see if you hear a difference in rythm also do the same with the spark plug wires. Is this an intermittent problem or is it always running on 3 cylinders?

240goslide · 01-10-2010, 05:29 PM

yea sorry my computed was screwing up. didnt no i posted twise. yea when i unplug the injector it sees to feel the same. ill check the wires to.

one step at a time. thanks guys
ill give you guys feed back

240goslide · 02-01-2010, 08:32 PM

ok so i no for sure its getting compression.. its hitting 160 for compression and i no for a fact its getting fuel. i pulled out the rail and there all spraying. i checked spark also and its gapped right and hits great. i changed my coil pack and thats not it. im lost as hell. i no its my nuber 4 because when its running ill pull the sparkplug wire out and it runs the same. if i do it to 1,2, or 3 it runs evenb worse (on 2 cylinders)

I cant figure it out at all. need help

very common for an injector to go bad.

give the injector 12 volts and a ground on the other terminal and you should hear it click

look man if your running on 3 cylinders its not the sparkplugs. its an injector not feeding fuel to the cylinder go to a junkyard, search here, or buy a brand new injector from autozone or something and replace it with the one that doesent make a diff when you pull the plug wires. just make sure to releive pressure by opening your gas tank, so fuel wont spill every where, and make a mess. pm me if you need more info

I'm currently having the EXACT same problem. I can tell you exactly what is is and how to fix it. It's the plugs from the wiring harness to the injector. Single cams are notorious for the rubber boots and seals drying up and cracking, therefore letting water and shit get in and corroding the connectors. Take of the harness from the injector then clean the connectors with a small screw driver.

If you want to get brand new injector harnesses, you can buy them brand new from Nissan right here. Just splice it from the one end.
