TW Chip issues

[TuRBoWHiNe]

Ok Gents,

I just put a new TW Chip in my truck. 03 7.3 with standard mods. When I go to start it up, the Wait To Start Light takes longer than normal and it then cranks with no start up. I tried it in all 6 Positions on the switch with the same results. When the truck was returned to stock, it started right up.

Any ideas?

Clean off all the contacts between the chip and the computer... gunk gets on there and causes all sorts of problems!!!.....

Are you saying to clean the contacts on the chip as well? The computer is clean, and i will clean it again just to check...

Dont clean it to much though... over cleaning it can screw it up!!!

If you think its pretty clean then it must be. Otherwise give tony a call because something with the chip may be wrong. Your wait to start light should stay on less than usual not more

I wonder if it is too clean. I had my dad clean it for me. He was an electronics tech in the Navy for 24 years. Now I'm reading all the don't clean it too much posts and am concerned. If that is the case, what's they cure?

A new PCM is the only way to go... how much brass is showing on the contacts of your PCM?

Not much at all should be showing

He cleaned it all off....

[TuRBoWHiNe]

By cleaned it all off, I mean you can physically touch brass on the entire contact, every one of them...

[Strokeorcroak]

can you get a picture of one? I am almost certain that may be your problem! to much brass is not a good thing... All he needed to do was clean the wax type stuff off the contact until a TINY bit of brass was showing. A new PCM is pretty spendy too!

Well, luckily he knows what the name of that wax stuff is as well. We shall get some of that, put it back on, and try again... I'll show a pic as soon as I find my cable...
