Added ts 6 pos now cranks but wont start

[bad12jr]

Do you know anyone with an obs you can borrow there pcm. I'm guessing it had a poor connection and possibly hurt the pcm.

After checking out all my codes I have a feeling I did something to the pcm also.. no unfortunately I don't know anyone in my area with an obs mostly dodges and chevys and new fords

 

[Mike For Mayor]

If anyone has more input please post!

From square one here. Without the chip in what does it do?

 

[Mike For Mayor]

It cranks very slow like the battery is almost dead

have you load tested the batteries. some times you will read 12volts and you have no cranking amps. i also have read that if you have the key in the ignition and plug the chip in to the pcm it will fry the pcm.

^^^^What he said. I have also heard that even just leaving the key in the ignition could cause problems. Additionally...I was also under the impression that there was some sort of capacitor energy stored...even with the terminals disconnected. Every time I put in a chip I disconnected the terminals...then turned on the lights and turned the key to accessory. After waiting 10 seconds I shut the lights off, key off and key out, then did my chip swaps. Maybe I'm just smoking crack...who knows.

This may also sound silly...but does your battery charger have "jumping" ability? The reason I ask is because I had two batteries that tested good...the green light shown brightly...but I had a biotch of a time starting the truck. If I jumped the truck...it started every time. Ended up having a dead cell in one of the batteries. As soon as I went to new batteries...life was good. I know you said you put the batteries in another vehicle and that vehicle started fine...but unless it was a diesel...or a vehicle that has the draw that our trucks do on startup...it really may not have proved anything.

I don't remember if I left the key in or not.. great...

 

[The Hosser]

here is the install instructions if you need them or just need a refresher.

 

[Mike For Mayor]

I installed it just as it says.. I don't know where I went wrong

 

[Mike For Mayor]

Just noticed my battery light is on

 

[The Hosser]

have you load tested the batteries? try that its simple and new batteries would be a quick fix and not to pricey. where as the pcm i think your looking at about 700 big ones.

 

[woodduck97]

You may want to get a amp tester cause your starter it self may be bad. My brothers on his IDI would barly want to start it with new batteries. Starter was drawing 600 amps. Most it should draw is around 300 i belive.

 

[Mike For Mayor]

Not sure how to load test them.. let me google itI real quick

 

[The Hosser]

need a load tester. if you don't have one i think almost all auto part stores will.

 

[Mike For Mayor]

I have this ultra cool meter that does everything but I don't think it can test a load so im gonna run them to autozone and get back later with the results

 

[The Hosser]

i know that auto zone has them. auto meter also sells a pretty good tester as well. but you will want to test them at half the cranking amps that are listed on the battery. not cold cranking amps. its a simple mistake and its one i made the first time i went to load test my batteries.

Bet you cleaned the PCM to far and fried it when the chip was installed...

 

[purpleheart350]

It might be just me but arent you supposed to remove the grounnd cables instead of the positive cables? I could be wrong and having my brain fart but if the ground is still on wouldnt it help in grounding/shorting out things?

 

[Mike For Mayor]

You can clean it to far? ?
