so i was trying to check the resistance on my bac valve i did everything the fsm said but when i check the resistance it comes out to .01 everytime so is it f'ed up or what the engine speed decreases when remove it and all that good stuff.
i'm tryin to figure out my hot start issue and i've already replaced tons of parts im just getting frustrated.

 

List all the things you have done.

I would suspect leaking injectors. Have you had them cleaned?

 

cleaned injectors
compression is from 95 to 100
thermo sensor is in spec
i removed the 3b wire from the ecu to see if it helped but it didn't
basically everything that would cause it i have checked so i was suspecting the bac might have something to do to it.

 

i was thinking somehow fuel can leak through the pulsation dampner vacuum line but i don't know if that can happen.

 

fuel can leak from the pulsation damper and can be one of the main causes of fires within the bay.
Resistance values are 10.7 - 12.3 ohms
have you tried to apply a 12v and a ground directly to it, you should hear it click.
If you are not getting your resistance values then you might have no choice but to try another.

 

I have a bac valve I'll sell you if you want to give that a try. I've also gone through a lot trying to solve my hot start issue, Rtek 2.1 finally solved it for me

 

.01 Ohms? Something sounds fishy here. That would be bad. Sounds fishy though.

Normally on a warmed up engine, you can remove the bac from the engine but leave the elect plug on it. Then key to just ON. The BAC should vibrate when the key is to ON. Do not pry or mess with the internals of the BAC. Just hold it in your hand and determine if it's vibrating or not.

Another thing you can do if someone is there to help you. Do as described above. Then look at the internals of the bac while someone turns the key to START. The BAC should go to and stay full open when the key is HELD TO START.

Full open is not much. It will only move about a quarter inch from close to full open. Again, do not pry or mess with that diaphram in the bac.

Warm the car up first if possible. If you can't, the bac should still go full open any time the key is to START. And HELD to Start.

 

are you sure you are using the multimeter correctly? if it is set to read the 1k range, then .01 would indicate 10 ohms. I would think that if it had olny .01 ohms, the multimeter wouldn't even pick it up depending on the tool of course.

 

yeah i'm using the multimeter right because it works while i adjusted the tps but when i put it onto the bac it shows up .01 here is a short explanation of what i did i turned the **** on the multimeter to 20k then i put the leads onto the tabs of where the plug goes into is that right? i can get a pic to see if im using it right thats what it looks like it says to do in the fsm.

also hailers i can hear something vibrate when i turn the key to on it is really loud im going to check to see if it is the bac but if it is, is it suppose to be loud?

 

You have your multimeter on the wrong setting, the reason the 20k setting works for checking the TPS is because the TPS resistance valve is in the 1000 ohm = 1k ohm range. The Bac valve resistance is between 10.7 - 12.3 ohms which is 100X less than the TPS resistance. Set your multimeter to the 200 ohm max setting and retest your bac valve.

Good luck with the hot start issue

 

The fuel pulsation damper doesn't have a vacuum line, you must have it confused with the FPR(fuel pressure regulator), and I have never heard of an FPR leaking fuel through the vacuum line. The FPD(Fuel pulsation damper is on the Primary fuel rail.

 

i just looked at it now i feel stupid your right i'll try out the right setting and see if it works.

 

The BAC makes a pretty loud vibrating sound if the engine isn't running and it depends how degraded ones hearing is.

So you hear the vibration. Just pull the plug off the BAC. If the vibration stops, then the BAC is working right. Put the plug back on and it vibrates again. Good. BAC is good.

The meter reading sounds fishy since the BAC is vibrating.
