angle/engine issues

[Fragz]

I went to the store 30min ago and ran in with my car running... the car is on a decent slope up hill in the parking spot......I come out literally 2min later and its idling like a--...so I get in and give it some revs and it just sounds off...big time off. So I shut the car off and try and restart it and it wont turn over...with some pretty violent shaking it felt like too.

So I gave it a few min.....started it again and it started but still sounded majorly off....so I gave it some revs and it backfired like 3 times LOUDLY then died

Could it somehow be flooded due to the angle? (I didnt think this was possible on EFI) or anything else that pops out? we are having a blizzard and it was in the pitch black so I couldnt see much, but everything seemed fine with plug wires/intake etc.

did you get it running again? could have sucked up all the crud in the bottom of your tank.

[Fragz]

nope its still there!....the spots not super steep or anything but its enough.....tank is about 1/2 full......

definitely a fuel/spark/timing issue though....but the distributor didnt move when I checked the plug wires so I doubt its timing (but the way the engine shook when trying to start it almost seemed it)......

Ill have a better look tomorrow if I can borrow a rents car to go look.

Timing belt jumped. If it starts let it idle and check the timing mark with a timing light

[Fragz]

whats stock timing on the KLZE anyways?

[wytbishop]

10ºBTDC at idle is standard for all A-spec K series engines. I have no reason to think the J-spec K would be different.

[Fragz]

aight I shall check tomorrow!....hopefully its not that....that'd be a pain!

[Fragz]

well I went back and went over everything obvious....didnt see anything wrong anywhere......start it up and same crap as last night. It wont idle so I couldnt even try and time it....it just starts....revs go up to 2500-3500 sounds like a--....then dies.......here are some vids via my cellphone of what it does:

first vid is just me starting it without giving it ANY gas:

second vid is me giving it some gas right before it dies

Sounds kind of like mine sounds when the VAF is unplugged.

[Fragz]

is the MAF for the KLZE and KL08 the same?

[wytbishop]

Well I’m not sure exactly what you’ve got going on in your engine bay but if you’re using the MX-3 ECU and its chipped you would be using the MX-3 air flow sensor as well. If you’re using some weird combination of ECU and air flow sensor it could be something else, but the clips you posted made me thing that the intake is the problem.

Did you make sure your intake is not falling off the throttle body or the air flow sensor accidentally got unplugged or fell off or something? Check the TPS connector, the IAC connector, the VAF connector, make sure all the joints of the intake are tight.

It’s getting fuel and spark and the timing is close enough or it wouldn’t rev when you when you hit the accelerator. It’s got to be either an intake problem or something important is broken.

[Fragz]

Yah I will go back tomorrow since its suppose to be warmer and take all the intake crap apart and put it back together

and Im using the KL36 ECU I do believe......so no idea what MAF the previous owner used to work with that....I didnt do that swap and I havent educated myself as much as I should have on this car just cuz its been a daily driver and not a project haha

for the hell of it I called Mazda to see what a MAF would be from them.....the guys like "ummm are you sitting down?" and he starts laughing....."Well I tripled checked and it would be $1,750.00 and we'd have to get it from Japan".....hahahaha like wtf? thats hilarious

[Daninski]

You use the JE 50 VAF and there's plenty of those here. Cost including shipping shouldn't be more than $35. Look on the plate on the VAF and it'll say JE 50. the only other one that we use is the KL02 but that shouldn't be on yours only 96-97 models with KLZE

this guy is right.
i would bet money ur timing belt has stretched and jumped a few teeth. stop trying to start it.
your just taking a huge risk.
its alot of work.
but
#1 buy a timing belt. ( its cheap and well worth it)
#2 pull the old timing belt.
#3 when removing the belt dont forget to put a pin in the pusher thing that keeps the pulley under tension (you will regreat it if you forget)
#4 put your number 1 piston at top dead center.
#5 set your cams.
#6 put the belt and tensioner thing back on.
and put back together.

You can check to see if the timing belt slipped by putting the disty rotor at #1, and then carefully putting something into the #1 spark plug hole, marking it, and rotating the crank a little each way, to see if your mark is the highest point by seeing if it goes higher, either direction of crank rotation. I'd do this before tearing the timing stuff apart.
