I honestly cannot say for sure from watching a video, but that's what I was thinking as well...worn brushes and dirty scored commutator?

The relay drops when the starter pulls so much current the battery volts drop below the coil threshold.

 

I assume that the bolds are correct.. Typically it takes a 30 seconds to 1 minute for the ECU to do a full shutdown. Sounds like a software initialization / synchronization bug in the either the ECU or BCM.... If you can hear the fuel pump run when the issue occurs, it's in the ECU..

I agree with the problem being the compression releases. You can retard timing to help control the issue but working releases need more timing to start (cranking pressure is lower).

I believe you offered this up in that other thread? My thought is, if you crank it before the check engine light is out, the ACRs may not have opened. If you "flip" the ignition, and the engine light doesn't come on, the ECU most likely has not triggered the releases. Sound about right?

When you say "hear the fuel pump run", I assume you;re referring to the priming step, then it shuts off?

My new start sequence is as follows.

- Ignition switch on (verifying I have the check engine light on, then cycle off)

- Engine light goes off, run switch on, and waiting for the pump to stop the prime cycle.

- Starter switch engaged.


When I follow this step, and I have not gotten the VINERR code. (Knock on wood)

 

I'm a little confused by this.. You say the engine light goes on and off when the ignition is turned on and not when the run switch is turned on (ignition on)? I would think that the engine light should come when the ignition is turned on and the run switch is already on or when the run switch is flipped on after the ignition is on and the run switch was off.

Add: Yes the priming step.. Do you hear it just before the failure occurs?

 

I have not tried flipping the run switch on before the ignition switch is turned on.

Just to be clear, I am referring to the switch on the dash when I say ignition switch.

To answer your question, yes, the check engine light comes on, and stays on for about 3 seconds, then off. The digital readout display, and the ABS light are also lit.

 

Sorry Mchad... Seams I am jumping in on another one of your threads

 

Wow, this became convoluted quickly. I still say your starter if f'ed. No way a 9.2:1 compression motor "needs" a CR to turn the starter unless the starter is week to start.

 

My 2002 does what it did at the 3 second mark, and I do the "run switch on, key on, turn it on before the engine light goes off" trick and it works great. The grab at the 6 second mark was what I thought you were taking about. That doesn't sound great but it may be an artifact of that whole starting sequence. My batt is good and the cables are tight.

 

Not even if the cam has an early intake close, 110 ci, compression releases that don't work, too much timing and a dinky battery?

 

So this is not true then?

"- Ignition switch on (verifying I have the check engine light on, then cycle off)"

Engine light don't do it's thing until the run switch is flipped?

Don't think you hijacked as the problem seems common..
