93,3.3L Danceing Tach w/key-on,eng.-off

[Luaulenny]

Started with car stalling when warmed-up and popping,Changed ECM ran better. But still missing like a bad coil,did resistance checks on coils when cold and coils warmed up,in spec. OK. Was told by auto stores they can test Ign. module removed module for testing till they saw type of module cannot test-it what a nightmare. Put module back in car now car won't start at all,no spark. After five can't-do's testing of module at auto stores replaced module with junk-yard module,did not work,Car still won't start. Bought new module after replacing crankshaft sensor,both fixs don't work.Did resistance check on 4-wire from ign. module to crank sensor ,loose dark blue W/white line connector on crank sensor ran alittle while (about 10 minutes)then stalled. Now Tacometer is bouncing with engine-off, key-on, and fuel pump allways running. Please Help, Cost allready out the door...Thank you!!!
