The shop she took it to checked fuel pressure last time and said it was good. I told her to have the injectors checked too. I had a late 80s Park Avenue that did similar things, and turned out the injectors were clogged. Could be spark too. I'm not in a position to try and diagnose it for her. My wife might think I was cheating or something helping a friend who's a girl. I hope her shop has a clue and can fix it right this time. Her boyfriend is clueless when it comes to cars.
That engine has an HEI distributor correct? Not the coil packs like the later LS engines. Could be the HEI module, plug wires, fouled plugs, coil going bad. Her charging system is ok, so that is good. Everything elese electrically works, so I agree it's likely somewhere in the spark system if it's not the injectors.
My 69 GTO did that when I flooded it, plugs got wet with gas, wouldn't start to save it's life.
