I was blowing smoke randomly, so I compress test and got a problem on a head, remove, machine and repair head, Now the dam thing does nothing but turn over. No spark, no injectors clicking. Fuel pressure good. Voltage good.
I jumped AB to get error codes. Nothing but 12(Diag Mode) and the radiator cooling fan runs.
I got cable usb to odb GM, I can read maf with the a- 10kOhm -b but I haven't acquired revs, spark or anything actually useful. No codes of course but of the array software to use it seems they all glaze over the vin #8 type 3 3.8V6
I replaced the prom. No change I pulled sensor plugs. No change, no codes
why can't I get an error code?
the darn thing thinks it's fine. I wonder if it would notice if it were on fire.
I have ordered a new calpak, eim and computer thats about 400$ in parts, I had to replace 4 years ago.
