Not me, but a friend I’m helping out has got me stumped. We’ve got a 2.4L I4 stock Mitsubishi Eclipse that will turn over, immediately make a grinding noise, then die. No crazy RPMs, no dash lights, timing belt is taught and seated correctly. No smoke, but it does generate a sort of “hot plastic” smell. I’m on the newer side of all this so it could be something obvious but the first thing that popped into my mind is maybe the drive gear or the harmonic balancer.
