Ok I was driving one night after a cruise and I got the road from dropping my friend off about to switch into 5th and my car just shut off all lights and cd player were still on I pulled over and tried to jump it but nothing replaced rotor button, spark plugs, ignition coil, and still nothing did a compression check and from drive to pass 1 & 4 had no compression 2 & 3 was half so any suggestions on what it might be.
