- Regal custom
I have a 1996 Buick Regal that cranks and only starts if i hold the gas down. Backfires, and will immediately die. Ive checked fuel pressure by the fuel rail and it was perfect. New battery. Replaced the Cam sensor, crank sensor , harmonic balancer. Need suggestions on what to check next....at a loss. Car ran great a month ago.
