Thanks for the suggestions, Neal, but I'm finding out the problem is a bit more serious. Seems to be an electrical thing. What is happening is when the weather is above freezing, when the ignition is turned on, before the starter is engaged, all the dash lights come on & the engine fires off fine when I engage the starter. When the temperature drops below freezing, the only lights that come on are the air bag, which goes off shortly, the battery light and the ABS light. The ABS goes off after a brief period & then comes back on. The engine will crank but the fuel pump does not send fuel and there is no fire to the plugs. Looks to me like the computer that oversees the engine is not booting! My biggest problem right now is that the weather is unseasonably warm & my mechanic says he needs the thing to act up for him so he can isolate the problem. We have it torn down & ready to trace the problem as soon as it gets cold again. Will keep everyone informed. If anyone else has had a problem like this, please let me know.
