Should you notice a difference using a timing light if you remove the spout connector? I timed the motor using a timing light with and with out it connected and the timing marks are in the same place either way?

Any Ideas?

Thanks

 

the spout connecter lets the computer take over base timing no matter what u set it at and w/o it u can adjust base timing...

 

Thanks but should the timing mark on the harmonic puller be at the same spot with or without the spout connector connected?

The truck is having a hard time turning over,( its chugging ) and I am wondering if it has to do with advancd timing. The timing mark is at the same place with or without it connected.

Thanks

 

i would say yes, time the engine as u normally would w/o the spout connecter. i remember reading that there was 2 marks on the h balancer or something...

 

The timing should advance slightly when you plug in the Spout connector. If you watch the timing at the same time as you plug it in it will move a bit. More importantly you should see the timing advancing when you accelerate (spout plug in) if it doesn't there is a problem in the circuit. I have a code 213 in the KOER test, the dealer mechanic told me this is a common problem and means nothing, anyone out there heard of this?

 

My truck never had the spout connector from the factory, there was a provision in the harness so I bought the litte module and plugged it in. It didnt do anything at all?

 

What year is this truck again?, I can't see it in the thread. It seems strange that they wouldn't have a SPOUT. Do you have a Haynes manual, it shows pictures of the different styles and places to find it. Is you ignition module on the distributor or on the firewall by the driver side. Regardless if you look at the timing mark while you are pushing on the throttle, and you see it advancing then the PCM has control over timing advance. I have a TFI ignition, maybe you have the duraspark. Did you remove the distributor at any time, maybe your off a tooth. Yes if the timing is too far advanced it can "chug" when it tries to start. you may be using the "wrong" timing mark.

 

My truck is a 94. I was looking at a chilton when I was having trouble setting my timing and it mentioned removing the spout connector, after looking all over for it unable to find it, I went to the dealer and the mechanic found the plug but there was nothing plugged into it, I got one and plugged it in but it made no differance, I finally just set the timing by ear. Mayby my ballancer spun or something, but I couldnt get any consistant marks.

 

Ok, now that makes some sense, someone forgot to put it in then. It's my understanding that you have to be able to "tell the PCM" to not mess with the timing when you set it's base value. That's why they put the little plug in so you can conveniently interrupt that circuit. Can you see the timing advancing when you rev the engine up? If not then the circuit has a short in it somewhere or the ignition module has a problem. BTW, I've had some success setting by ear, ie, back from pinging under load. In the end, if you have the timing set such that you get acceptable acceleration but it doesn't ping too much under load, you're close. But..... if the computer (PCM) isn't advancing the timing then you're only running on base timing and that isn't acceptable, you must fix the problem. It is a little hard but you can find TDC by putting a wire or something that won't break off in #1 and feel for TDC.
