The car was bought already swapped with 99 ls1 and tranny, 230/232 cam. 3600 stall. Tuned by pcm4less, harness was claimed to be reworked by speartech but im finding nothing that shows it was done by them(the original fuse box was also retained.racetronix hotwire kit and pump. Up until a few days ago crank perfectly, ran rough though(needs retune for cam an stall i was thinking). Tried to crank got a stumble and it cut off. Continued to try an crank but no start. Recharged battery, connected scan tool, primed pump(pump came on,had pressure at rail) attempted to crank. Scan tool went out(no power to ecm or pump). Checked relays, three bigger ones had power in and out, smaller relay had power in, not out. Replaced smaller relay (fuel pump came on, yes!) Tried to crank,(went back out no!also forgot to hook up scan tool, retraced wiring to each relay(to my limited knowledge their wired wrong! Hot wire was next to ground, but the relay shows them to be diagnol)Not sure how it ever worked in first place) removed relay, noticed plastic is burnt in the location of ground wire and gray wire( not sure what grey wire is yet) removed wires from fuse block, connected hot wire to 86, ground wire to 85. Got click(relays sounds like its working)meter shows no power out other legs. Tested other relay, samething(guess i fried em, not sure though checked for power at coil connector got 12v tested fuel injectors 12v now im really so know i need to know 1 how was it running if it was wired wrong? 2 is my pcm now fried? 3 what does the grn/wht wire and grey wire go to? 4 where do i begin to fix this issue? Thanks in advanve any would be appreciated.
