Default The 89 Bonneville won't start!!!!

Hey everyone...got little problem seem can't figure out!!...The other day I was getting ready to go to work, cranked the car up and was pulling out of the driveway when all of a sudden it just cut off. It gently cut off..not a sudden rough stop just gentle...if it means anything... Me and My dad replaced the ECM and Coil Pack but still no spark..and its getting fuel...soo what is it left that couldn't keep it from getting spark???? Any help is appreciated!!!


Thanks,
Matt B.

so, the car wasn't very warm then... Has it ever done that before? How'* your Volts?

*EDIT* nice 66 C10, that was my VERY first ride when I was 13. It was a longbox, not a stepside though...

yeah, does it crank at all now? Do you have interior lights? Might need a new battery and/or alternator.

The only other thing I can think of is your crank sensor. Mine failed and my car would randomly just shut off, and/or I couldn't get it started.

Let'* see if anyone else has some idea'*....
