tick tick tick from the AFM

[ek-9]

So yesterday I decided to check all the vacuum lines on the car. They were all plugged in to the right spots (eventually) and check a few more connections here and there. I tried cranking her over but she wouldn't start. And then I heard this weird clicking from the AFM. It stopped after a while and I went inside cause it was too cold. Then my parents came home a few hours later and said that my car was clicking. It was the AFM. What the hell was it doing? And what was it doing it?

Would the next logical step in trying to start her but to check the ignition system? I know fuel is getting to the rail cuz I had some shoot out before when an o-ring was crooked. Any suggestions?

Rather than popping her open, and ruining the integraty of the seal, see if you can find a new one. I know nick had one or two, so did some of the other guys. I opened my AFM and turned it up, but now I wish I hadnt. I have no idea why it would be clicking though.,.. :-?

if you need a AFM, i can lend it to you,
because my brother's car is just sitting in the garage

replace all your fuel injector o rings and seals.
they are cheap and you won't have to worry about fuel leaks at all..
Mr_sinister can tell you all about that!
do you get a spark?

i replaced all the seals, gromets and o-rings. it's just that I had one a little crooked :P, plus, I loosened the cold start injector line and forgot to tighen it. But the fuel leak should be an issue anymore. I have a spare AFM from the parts car. I'm just wondering why it's ticking. Maybe the flap is caught on something. I haven't checked for spark. How do I do that? :P

me = noobie.

Thanks guys. I am fighting everyone in my house and everyone that I know that has told me the car has been sitting too long (13 months) and I just suck and know nothing. For the car to start, would be my greatest automotive accomplishment and I can throw it back in everyones face. Especially my dad who asks if he should bag up that garbage for thursday pickup. :P I really don't want a shop to touch it ... that'll be the last resort.

usually when you hear ticking like that on start up, its an idicator of a faulty starter. The starter is not connecting to generate electricity therefore it makes this clicking sound every time you turn the ignition.

be sure that the ticking IS comming from the AFM and not any where else.

if you are sure its the afm, pull it and put in a nother one. if it continues to click, then you know that A) its not the AFM or B) you have really bad luck and have 2 shitty AFM's.

if the car doesn't even turn over, then your problem is farther than the afm. No turn over, means that no power is being supplied to the ignition system. In which case, i would bet my bottom dollar its a shite starter or an improper ground.

in any case, slowly trace your steps.

no turn over means no power, therefore you should look at: the ignition coils - wires - fuses- relay - starter - ignition column - battery terminals - battery - grounds

if you get turn over but a constant waw-waw-waw sound i would check: fuel supply - spark plugs - spark plug wires - distributor - rotor - timing

thats the best way i look at it....process of elimination.

Thanks. I'll try those steps. I pulled the starter a few weeks back and checked it according to the shop manual. Seems fine. The AFM is clicking ... like it's flapping open and close constantly ... but only after I try starting. I'll turn the key, the starter would crank the motor (i know because the cam gears have rotated) and since it's not starting, i stop trying and then I can hear the clicking. once I unplug the battery and plug it back, the AFM is back to normal. I'll give the other one a try and test my luck ... altho I've never walked away from a casino with more money than I went in with.

Here's hoping .. fingers crossed

Well if you need one of a 1988 GTS. I have one. Dunno if its compatible.

is it a.. tick tick tick... my car has that, but i thought i might have a bent valve or a lifter or something.. never thought it was the AFM.. do your RPM's go up and down a bit.. or the engine seem to run at higher than 1000 rpm a lot?? hmmm... I wonder if its my AFM now.. :roll:

your problem is not a bent valve or ruinded lifter.

the valves are non-interference so i highly doubt they are bent. unless the previous owner(s) went in and muddled around with it casuing the valve to be damaged.

the lifters are bullet proof ont he 4age. hardly ever damaged unless someone fucked around with it.

unstable rpm could mean unstable vacum pressure. be sure to check all the seals and hoses.

the afm very rarely goes unless its been tampered with.

timing could aslo be the key...which i would bet all my horses on. if the timing is out of wack, you're gonna get a really screwy idle and power curve.

ahh ok! plus the fact that I STILL need the damn fuel filter to be replaced might help on the rpm thing.. grrr.. i might need a new fuel line! :x it looks like it's rusted onto the filter.. what you guys think? will it stay intact when the filter is taken out.. or will it have to be replaced if it looks like its rusted?

[fatredcircle]

the outside might be rusted, and the nut might look rusted but it shouldn't be that bad inside where the fuel flows.. when you pull the exisitng fuel filter off, it should be pretty clean..
but to be safe about it, if you feel you need to replace the entire line, do it.
i don't think u want fuel spuing out everywhere especially when it may cause a fire.

Hi EK9

It's cruzzinn the one who sold you car, I feel bad on all the probems you have had with the car, If you want I,ll buy it back from you plus what you got in it, but I bet you still don't want to sell it, If you going to keep it I still have those supra wheels you said you wanted, would like to get rid of them soon, they take to much room in my small garage, I also have a set of after market wheels you mite like ? or I will be selling them soon, my garage is just too small.
As for the pro :oops: blems you are having.
#1 Check for fuel:
Have you cleaned the injectors, if they sit around for awile they get gummed up and it sounds like it is your cold start injector clicking trying to squirt some fuel, this maybe what you here clicking at the AFM as the sound will funnel down to AFM as it is fairly close.
#2 check for spark:
Pull a plug from engine and leave the spark plug wire conected and lean it close to block, turn engine over and you should get a spark between plug and block.
#3 check the AFM flap:
Disconect the hose to air cleaner and stick your hand in the AFM and see if the flap will move, it should move a little bit and not need a lot of force, from sitting for over a year it may be stuck, may just need to be worked lose from corosion from condinsation, maybe some WD40 once it is free to lubricate it, don't worry about getting WD40 in intake it won't hurt if anythig it will help to fire it up.
#4 Check your AFM first because if it dosn't open you got no air, Then do #1 and #2.
Hope this helps and keep me posted, I would email you but I deletted your address.

hmmm... this is weird too.. the last couple of days, the car feels like something is restricting it when i go into second gear and gun it.. for about a second then it kicks and goes.. maybe cuz it's cold out.. but I'm doubting it.
