You need to replace the head lamp switch. This is an internal failure.

In the hot weather I would use 5/30, but since its going to be winter soon, use 10/30

The firing order is 1342

by pass the starter motor see the diagram attached 1). and see the normal diagram2)2) normal diagram

sounds like a fuel issue i would recommend replacing the fuel filter it is a cheap and easy fix after that if the problem persists then i would take it to a shop to get a free diagnosis in order to find out if it is your fuel injectors or your fuel pump. more symptoms of a bad fuel system would be extreme drop in rpm when put into drive, choking or sputtering, large amounts of smoke from the exhaust pipe, or complete shut down of motor after running.if you need any instruction on removal and installation of any part please comment back on this post thank you, and good luck.

Try to check the ignition coil, when you driving it become hot then the car dies end won't start. After awhile when it's cold, then it will start. Replace the ignition coil.I hope it solves the problem

Depending on the model, it may not be wired for rear speakers and you will have to run them yourself. They were doing this in the late 80's early 90's to save money on wire. Otherwise, the wires normally will be where the rear speakers are located. (Rear speakers may not be installed from the factory so look for the holes)

see the diagram attached, and proceed according. God bless you

Have you place the head gasket on the block the right way round as it sounds as if you have blocked up the oil feed galley. I imagine you used a aftermarket gasket kit and it may not have a oil hole for you engine.. May have to pull the head and check.
