Jiggle the wire connectors going in to the computer under the hood -- first check battery cables/terminal connections at battery -- beleive it or not, connection could SEEM good because you get crank & lights, but if it's faulty, loose, engine won't start - computer requires good solid voltage flow.. next check a fusible link very close to the battery off of the positive cable. check fusible link carefully. this could cause your problem for sure.
Ok...you mentioned that there is no spark coming from the coil when it's in no start...Is there power from the alternator going to the coil? One other item...If the timing chain is worn and stretched, it is possible that the cam sensor and crank sensor are out of phase with each other, just enough where a temperature difference will change starting ability. One question...while in no start, have you tried changing the throttle position while cranking to see if it lights at part or 3/4 throttle?
Long Crank Time Due To Possible Contact Of Camshaft Sensor To Camshaft Gear
This bulletin involves the replacement of the engine camshaft sensor.

NOTE: This bulletin applies to vehicles equipped with a 3.8L engine (sales code
The customer may experience one of the following conditions:
a). Long engine crank time.
b). Two engine start attempts prior to engine starting.
c). Due to the “TIP Start Feature” on automatic transmission equipped vehicles, once the
ignition key / switch has been released from the “START” position, the starter may stay
engaged for up to 10 seconds while the engine attempts to start.
The above conditions may be due to the position of the camshaft sensor to the camshaft
gear. The sensor spacer gasket may have come loose during engine assembly and
caused the camshaft sensor to be adjusted too close or in contact with the camshaft gear.
If the above condition is present perform the Repair Procedure.

instead of cranking, just leave key on for a minute...if there isn't a delay starting after that it may be a bad drainback valve in the pump. You can either live with it for a while or replace pump...but check that it's not an injector leaking into engine first.(usually if that's the case, leaving key on will lengthen start time and give a puff of black smoke on startup)
This seems like a fuel pump or fuel filter prob. The pump more likely. Will it fire up with gas poured into the carb? If so the pump. If not, we will need to look for another prob. Don't buy parts you don't need! Frankster016
