1. stop saying sorry all the time..

2. you can "repair" some cracked coils by coating the sides with a thin coat of rtv sealant, let dry, reinstall when dry..report back findings.

Make sure you get the rtv in the cracks.

92maxima92 · 12-02-2008, 07:38 PM

Its the top part of the coil inside the engine not outside

92maxima92 · 12-02-2008, 07:39 PM

Whats RTV sealant

*CapedCadaver* · 12-02-2008, 07:40 PM

greeny.. what makes me curious is... how would bad coils make the tach drop to zero while the tranny was still forcing the engine to spin?

Who knows dude, but cracked coilpacks will most definitely cause a nice stumble while driving, trust me i know.

It is entirely possible that a few of his coils have fail internally, along with the cracks, i have had two fail internally.

how do i post a pic on this thread can i drag the picture over?? Would it show up where your typing at or just a bunch of letters but will post the picture??

tech gets its signal from coils or ecu depends.....for example, 1 cylinder 500 sparks X 2 ---> 1000rpm so u can see now 6 cylinders 3000 sparks ( do the math ) to wat that it comes to 1000rpm....ECU calculates all that stuff and wen it doesn't get enough sparks( cracked coils) and calculates wrong and tach goes down....correct me if i mixing something dere....

there we go sorry it took awhile

92maxima92 · 12-02-2008, 08:09 PM

Thats whats causing my problem possibly??? And Do you think i should check the back three??

92maxima92 · 12-02-2008, 08:13 PM

All 3 of the front ones look like that

The rears don't normally crack due to they are not inside the heads like the fronts, heat damage is the cause of the cracks.

But go ahead and give them a check if you want

92maxima92 · 12-02-2008, 08:32 PM

ok but could this cause the problem im having??

Yes...

But take into account that none of us are actually under your hood, so to say for sure this is the cause with "actually" looking at the car is not a 100% diagnoses.

Cracked coil packs can wreak havoc on the ve engines drive ability..So try the cheap rtv fix first, if no go, replace them.

92maxima92 · 12-02-2008, 08:33 PM

Thankyou so much and the rtv stuff might be a cheap fix?? And if not where could i find the cheapest coils at??

it would def cause the car to run like crap. i don't know if it would shut the power off completely tho.. or turn the tach off...

Unfortunately, coils are not cheap.

autozone= $73 per coil

Dealership= $85 per coil

you could try the classifieds section here, or j-yard coils<--beware of getting the same crap you already have from the junkyard.

92maxima92 · 12-02-2008, 09:32 PM

Dont know if this matters but sometimes when i push on the clutch the rpms drop below 500?? Is that sopposed to happen sometimes it gets close to zero

well if you are driving and just let go of the gas and push the clutch, rpm will fall back toward idle... it shouldn't really ever go BELOW idle tho. but when your rpm shows zero while, you aren't touching the clutch pedal are you? you're still in gear, foot off the clutch?

92maxima92 · 12-02-2008, 10:02 PM

Yes correct ill be moving at the time clutch not being touched and still in gear and the rpms drop completely thats when i touch the clutch because the car is slowing down. It just seems like the gas is just cutting out on me.

but, keep in mind, if the rpm is reading zero BEFORE you even touch the clutch pedal... the engine is still physically spinning, even if the tach reads zero. As soon as you push the clutch, it really does go to 0rpm, but the way a manual tranny works, regardless what the tach says, the engine will still be spinning until you push the clutch. To me, that's the most important piece of info in the thread, is if the tach falls to zero BEFORE you push the clutch.

92maxima92 · 12-02-2008, 10:18 PM

Could it be the ignition coils that greeny is talking about?? I checked the front 3 and they are all cracked show in pic above. If not what should i look for next??

if the last sentence in post #71 (rpm says zero BEFORE you push the clutch) is TRUE, then that, to me, still indicates the cam pos sensor. cuz that's the part of the car that reads the RPM in the first place.

I'd test it myself, if i had a VE. but I don't, i have a VG. tho i could perform a similar test... kindof.

a test you can try: go out on a road that has VERY LITTLE traffic, drive 45mph steady. then turn your key to ACC while going 45mph. of course, your engine will be off, but still spinning. push on the gas pedal a few times (you should hear the roar of the intake, as opening the throttle allows more air into the engine) then after 5 seconds, turn your key back to ON (don't hit Start! the engine is still spinning!) and resume driving. Tell me if that feels kindof like how the car behaves normally. (the difference is that this time, your speedometer WILL drop to zero, at the same time as the tachometer.)

92maxima92 · 12-02-2008, 10:31 PM

RPMS never go to zero when i push the clutch they never do unless the car is off or when the problem occurs??

yea that's the way it should be. if your car is on, then rpm should never read zero. it should always be 700 (idle) or higher (driving the car). when i said pushing the clutch, i was ONLY referring to pushing the clutch WHILE the problem is occuring. not in every-day driving situations. as long as the car is behaving properly, then no, pushing the clutch will not make the rpm say zero. sorry for that confusion

92maxima92 · 12-02-2008, 10:50 PM

Could cracked ignition coils cause this?? Im gonna take a video of the problem so everybody can see whats going on.

video will be good. again, i don't have coils like you, so i can't say for sure. but i saw nothing in the FSM (shop manual) that would cause me to think that bad coils, whether one, some, or all, could cause the tachometer to read zero when the car is moving in-gear. That's why i keep bringing up the cam pos sensor as my opinion of what is wrong.

don't get me wrong-- if the coils are cracked, DEFINITELY try and fix them or replace them. I just personally think there's more to your problem than that.

As u say, some of the cracks yes, not a intermittently failing coil. Then Nissan also installed there some electronics (to be fried in the hottest spot): actually what are the components lurking inside? I guess at least few transistors... Gouging them out for repair would show some skill.

92maxima92 · 12-03-2008, 09:06 AM

New info on this!! Car wont start now. I dont know whats going on here i would love to fix it but its gonna get junked soon. Somebody please help!!

Won't start as in..The starter will turn the engine over, but will not fire?,....or starter will not turn engine over?

Make sure you didn't leave anything unplugged, check all electrical connections on the engine.
