No start??????

[scot5146]

Hey everyone I was still in process of figuring out the ABS brake issue when I went to turn on the Suburban today and nothing...

I turned the key and all the power works just nothing, I replaced a battery today thinking that was the problem but still nothing...

Did all the usual, in and out of park, rolled it backward, volt meter on the batteries [both good] wiggled the pmd nothing...

I am missing something and not finding it... Help Please????

Starter switch down on the colum?

Could be the neutral switch.

OK so its a 1999 K2500 Burb 4x4 6.5 diesel all the good upgrades have been done...

I am leaning towards to issues, the neutral switch and the PMD

I tested an old PMD and it started but I had to jiggle the shiftier on the column...
So hence my thinking there are two issues... I will dig into it on Friday, I am off work and have time.

Any other ideas?

Thanks

Mike

When you say "nothing", do you mean it turns over but doesn't start? Or that it doesn't even turn over?

[scot5146]

Ok so I am not sure what I am doing wrong... This is the third PMD in 2 years; I have tried the Gray Standine and the Black Dtech...

I have a long remote cable and a good heat sink, I put it down in the back of the bumper where it’s nice and cool.

{Maybe it’s getting wet, I am not sure}

I can’t find the right combination to mount this stupid thing; I am almost ready to switch to a manual IP pump...

Should I mount it in the cab? Under the dash maybe?

Please Help, Very Frustrated, I have spent about $800 bucks in PMD's over 2 years, this is getting ridiculous.

Thanks Again

I'd try it on the inner fender. Do you do a lot of idling with little air flow?

[scot5146]

Yeah I seem to do more around town driving, I am just trying to find a spot that wont get to hot and also stay dry...

So, what exactly is it doing or not doing?

Will it crank?

My 99's ABS issue was actually a bad ignition switch. As was my 4wd inop...

When cold my switch causes more issues. If I slam the switch (I've removed the lower column cover to access it) with my palm. Everything works normally. However when it's -20 or worse, my fan, cruise, 4wd and ABS get stupid, till I give it a smack. Not a cheap part or I'd just replace it, again. Darn Napa

Make sure that you use heat transfer paste or a heat transfer pad between the PMD and the heatsink.
torque the screws to 25 inch pounds

And be sure that you have a good extension cable,perhaps some dielectric silicone around the weatherpack seal to prevent moisture.
You have the very best location to get long life from a PMD now.
Also be sure that the IP harness ground wire is fastened to the top of the IP and no where else.

I have done all that you suggested and I am still having problems with the starting and it dying intermittently... I have ordered a new PMD and am waiting for it in the mail to install. I am 90% sure thats the problem, but will keep informed once the new one is intalled.

Thanks Again
