Cranks hard but no start

89 328 GTS. Car started right up fine and I moved it into the driveway to swap cars. A few minutes later, I go the dreaded starter click but no starter that I have had for a while. Usually a few on/offs with the key and it fires up. Even replaced the ignition switch a few months ago hoping to get rid of that problem but haven't. Anyhow, the starter engaged the second try, but then the car sputtered. I tried several more times with the engine cranking very strong but no start. I smelled the right tail pipe and could smell gas so I think the fuel pump is running. I even swapped the two relays on the dash that say fuel pump with relays that run the headlight motors and window motors that I made sure were working before swap. I've giggled wires under passenger footrest and under dash but don't know what to try next. Had to have my wife help me roll it back up a slight incline into garage.

What is the sequence and the wires that create the spark and how do I best check for spark?

Is there a bunch of relays that kill spark? And anyone know anything about an Alpine alarm and if it has a "no start" connection? Thanks
