SKYLINE WONT START ! HELP !!

SKYLINE WONT START ! HELP !!

So hear me out first guys, hear the full story it might help !!

i changed my Blitz Pod filter to a K&N one

Car was running fine, and on my way back home I decided to give it abit in the tunnels, after giving it all the sudden my car started choking or chugging and I thought my engine died, but it was still running, it runs fine till I step on the pedal half way it chugs and struggles and pretty much wont let me Go over 3,000 RPM so I thought maybe it's the POD that's acting up the AFM cause it felt like it was the case.

 

So the next day I changed it back to the Blitz that I originally had earlier on and went to drive it around and it was back to normal "woooooooo" and as I got close to home it did it again the chugging and choking like it was gonna die, so I was f.. could it be my spark plug or coils. 

So the next day I changed my Spark Plug, it was a BKR5EIX-11 which isn't recommended but I had it laying around so I replaced it, my old spark plug was black and burnt on the tip so I thought yeah maybe this should do the trick!

Plug everything back in and.... 

it CRANKS AND STARTS FOR A SPLIT SECOND AND immediately dies out and I only have one conclusion left, the Coilpacks but I want to see what you guys think

 

-every hose is plugged in correctly and tightly 

-strange thing is that before I change the spark plug the car was running but a weak start up so I thought Spark plug but now I don't even know anymore.

PLEASE HELP ME GUYS !! Could it be the coilpacks ?? Could the spark plug have anything to do with it, even if it's not recommended it should still start up, it's gapped at 1.1 which is how the plugs came (Bkr5eix-11)

Get a brand new set of BCPR6ES and gap them down to 0.8mm

If that doesn't work unplug the AFM and see if it starts. If it does look up the "how to" on cleaning the AFM

[jmknights93]

Why did you replace with BKR5EIX-11? I'd suggest purchasing a brand new set of BCPR6ES as mentioned above.

[Jacko1987]

Sounds like a fuel issue

[Jonic]

I replaced it with bkr5eix11 cause I had it sitting in my rooms for years for my NA/R34 which was recommended. And nah doesn't seem like a fuel issue, I got half a tank and I can definitely hear the fuel pump just before starting the car

[Jacko1987]

Won't hurt to change the fuel filter maybe

[rx-line]

From what we can tell the only thing changed was the filter, I would look at the Maf extensively to check for damage.

My car would not start and sputtered going into boost when the plugs were fouled. Also check for ground wire to coil packs/ignitor. 

 

[Jonic]

Rx line, thanks for that I'll give it a shot and see if that does the trick

[Jonic]

Turns out to be the Coil Packs and I also changed the spark plugs to BKR6EIX-11 now it's starting up and running much much better than ever before, thanks guys

Whhhyyyy not just use copper plugs and save yourself all that money?

[Jonic]

Because I get them cheap as cause I know a guy from Repco

[jmknights93]

Could have purchased copper for even cheaper ....

[Jonic]

Okay after installing these, I'm back to square one, it wasn't the coils or the spark plugs! I'm still having trouble getting the car started :S HELPP

[KiwiRS4T]

Pull the fuel line off and see what comes out when you turn the key. Pump could be on the way out.

[89CAL]

So what ECU is the car running?

[Jonic]

The ecu is stock and fuel line is good, I think it's the AFM since I change the Pod around and maybe it bounce around too much and played up perhaps

[Steve85]

Have you considered that it could coincidentally be an alternator or battery that is no good? It's a big leap, but you should probably just check how many volts you have on the battery terminals before and during cranking.

Well just unplug it and see if it starts.

[Jonic]

LOL so I tried starting her up after work and guess what, it started weak and actually stayed on, Tried it again 10mins later and wallah it's starting up and running all good again ! Haha what a confusing moment, what in the world happen ??

[Jonic]

Now everything it out back together the car runs but the PROBLEM OF THE LIMP MODE IS STILL THERE !! I can't even rev pass 2000rpm, even when parked! Something must be playing up and I'm thinking it's the AIR FLOW METER. Ever since I changed the Pod Filter the problem started, but the thing is I changed it back to normal but it's still limping, I can't even hit 60Kms on the road :0
