Clearly this is a Grounding problem....the chassis is not seein' PROPER ground off the 1/0 battery cable...this connection gets corroded from repeated 300 or more amperage requirements...from the cable TO the chassis...after a while thru "blue" spark creates a layer of semi-conducting ground...this dodgy ground is what is supporting your ECU, ignition, fuel system and dashboard components....cannot see a good connection...you must disassemble the 1/0 black cable lug and wirebrush it.....with a coarse wirebrush and the spot on the chassis too....reassemble and you're good to go with no further complications (damn sounds guruie)~
