ive been foolin round with a new engine for a few weeks and it still doesnt run right. so i decided to put a scanmaster on it to find out why its so rich/missing only to find that it isnt getting an aldl signal (the scanner works and i tried the ground test that bob posted and it wakes up again) - what is the problem - my ecm? this really sux that i can scan the new engine to get it right.
 
make sure ur REALLY HITTING FULL THROtle!!!! scan master wont start recording until the TPS hits over 3.0. lol i only know this cus i had the same problem the first time i got scanmaster. Just press the fu ck out of the accelerator when u go for a run. let me know if that worked or not.
 
I don't think that's what he's saying. You need a good ground to ensure the SM will actually turn on. I use the screw on the side mounting point of the ALDL connector. If you are concerned with the ALDL signal, do the paperclip test (a bent paperclip inserted in slots A & B in the ALDL). If your check engine light starts flashing codes, you should be getting an ALDL signal. Just make sure SM is hooked up properly (to B slot I think).
 
cant read codes the old fashioned way - see my other post in the general tech under "running outta ideas"

some folks are saying i may have a faulty prom.
