88' 420 SEL won't start

About a month ago, my car wouldn't start and I replace the relay for the fuel pump. Seemed to fix it until last weekend, when the car wouldn't start while on vacation in Indiana. finally got it started after using starting fulid and a jump for about an hour. Got it home and it died. Rotor and Dist. cap seem to be worn, but plugs still fire. I pour a little gas into the intake but the engine does'nt hit a lick. Fire to the plugs, gas in the engine, but nothing...engine was running when I shut it off so I don't think the timing slipped. Havn't checked compression but it seems ok. Any ideas? Please help!
