Recently bought a 93 hatch with a b18b1 in it. Drove it all 55 miles home with no trouble, other then the idle was super low, about 500 when the motor was completely warm. When the idle would dip that low the dash lights would dim also. Got home and let it sit for the night and tried to start it in the morning and just would not start up. Changed the plugs, plug wires, and rotor. Im gonna replace the dizzy cap tomorrow, its an MSD external coil, but it seems to be warn down. Any ideas? Fuel pressure gauge reads 40 when i try and start it. I never messed with anything, but just need to pinpoint why the motor wont start now, I know its got something to do with the super low idle.

 

any ideas? need this bitch to start up!
