Common problem is pick up in dist... ignition module is the first thing but you have replaced.... with out a lab scope to see the signal i would confirm what i am missing make sure good fuel pressure big problems with fuel pump relay... if fuel press good.. then make sure power on coil during cranking.. if good then clip the ground clip on test light to the positive battery terminal and back probe both wires on coil while someone cranks one wire shoul have pulse look good.. if good should have spark if not chuck coil.. let me know

Need to know why a 97 mercury cougar won't start until cooling fan and fuel pump stop running


I would think it's a problem with (CCRM) constant control relay module . This module has relay's inside that control the fuel pump , cooling fans , A/C compressor clutch , PCM - engine computer power relay . And thier are electronics involved , solid state circuity . Google CCRM

Start with engine cool. Remove rad cap, top up coolant, start engine, & turn on heater (not defrost). let it run until up to normal operating temperature & radiator fan comes on, then shuts off. Let it do this about 3 times before you put rad cap back on & top up return bottle to proper level. Every once in a while, rev engine slightly for a few seconds while your doing it, to speed up bleed by increasing flow. Keep an eye on temperature gauge for too hot, and fan not coming on, if so, shut it off.

97 cougar 3.8l no start until fan and fuel pump shut off


Same car, same problem. Finally fixed by changing out PCM (computer module behind passenger side kick panel). Car runs much better too.
