Brake light switch and neutral safety switch problems

[Supra_Freak_7m]

Oh, I thought you had an auto, i saw when you said fifth gear too i just thought it was a typo. In that case i have no idea what would cause the car to die between shifts. i think the first thing to do is make sure you dont have a diagnostic code stored in the computer indicating possibly a bad sensor (MAFS, TPS).

Check your connecter on your MAFS and make sure it is not loose

Also, check your negative battery cable, make sure it is tight and clean at both ends. The cable should be grounded to the block on the driver side pretty much directly above the engine crossmember. If you have to remove the bolt that holds it on, dont worry it is a dry hole, neither oil nor coolant will come spewing out of it

try those and see if that works

NOTE: there are instruction on how to do a diagnostic in the FAQ
