Occasional no start/stall
So I've recently picked up this 1988 Acura legend L coupe. It's a 5 speed with the 2.7l and 112k miles on it. Previous owner said it just sat for a while so they just wanted to get rid of it.
Ever since I've brought it home, it's been driving me crazy with the occasional no start. Every other time I try to start it, it will crank, but won't turn over. If that happens, I let it sit for 3-5 min and it starts just fine. If I crank it and it doesn't start, it smells like fuel, so I'm assuming I have fuel pressure. Even more rarely (happened 3 times so far), the car will stall on me. I was able to pop start it two out of the three times. The third time I just coasted to a stop while trying to pop start it. The rpm and speedo looked normal, but the engine wouldn't turn over even when I put it in gear and dropped the clutch (I was moving at 40 mph so I tried pop starting in 3rd, 2nd, and 1st as I slowed down)
So far I've replaced the fuel pump, ignition coil, ignition switch, plugs, fuel filter, and the main relay.
Any ideas what the issue might be?
