1993 lumina apv cranks,no start wiring problem?

[mrtooter]

hi i have 93 lumina apv 3.8 that just quit on the highway, has no spark, replaced crank sensor, ecm ,coil packs and computer , came up with error 42, with scanner ,cleared codes after replacing said parts, no getting any codes now and still no spark, unlpugged ecm and c/s cranked engine over reread computer , no codes, no spark, error 42 relates to crank or grounded wire, anyone have similar problem , find any shorted wires? i did visual check only didnt c anything, the crank/sensors was replaced twice just in case it was a bad one, ecm module was from the bone yard, tried 2 differents ones, prom was taken out of my computer and put in other computer before i replaced it, me and my buddy have access to most mechanics tools u can think of, any ideals besides testing the wiring system from scratch?

Take the ign module to AZ for testing also make sure the harness from the crank sensor the icm is intact, check all the fuses.
