Re: Need help / idea - no power and erratic idling

"Oh... and quick note... when I put a jumper in A and B of the OBDI plug to get the flashing lights to read the code... no service engine soon light. The shift light comes on and stays on solid. "

This is suspect IMO. Do you have a way to hook up a scanner to see if it can provide any info? Can you find another truck in the junkyard that you can swap the PCM from?

Toy list:
1995 GMC Yukon 4dr 2wd 5.7 Vortec conversion, AAM TracRite, Lincoln Mark VIII fan conversion
1979 Mako 23 CC
