Get one of the Hobbs or hanes mechanic books for your year and make of vehicle. It's got everything inside .

Need three (3) things for an Internal Combustion Engine to run, FUEL, COMPRESSION, & IGNITION. To check spark, pull a plug wire and connect to a spark plug that is sitting on a metal (grounded) surface and crank the engine over. You should see a spark on the plug. If there's no spark present you have narrowed it down to an Ignition Problem, but there's still a mulitude of potential problems that'd cause that. Fuel injected engines do require much more fuel pressue than carb'd engines, so that may need to be checked (external fuel pressure gage) if there is a spark present.

if they are not on the driver side then check under the hood. there are two fusible links under there

It sounds like you have a spark plug breaking down under load.Try them first then get back to me good luck

well the temperature control gage is connected to the engine block and consists of 1 wire for the reading of the motor heat either the sensor is going bad or you need to check your coolant levels in the radiator make sure the engine is cool before opening the thermostat cap to the radiator so not to get burnt ...also make sure the wire itself is not grounding out on the engine block to give the gage to give such a readout look to the engine and usually on the drivers side lower the plug wires you should see a plug with a wire coming from it ensure the wire is not rubbing on anything .

linkage on inside of door has come undone. take off inside door panel and you will find a small rod that goes to the lock mechanism where the door closes opposite the hinges. follow the handle to the door lock.the nylon bushing may have broken.they are cheap to purchase at auto part stores.

Look for alarm Brain box and look for wires coming out black and red going to valet switch. to turn valet on turn ignition in ON position and press-switch or flip depending on the type of switch. If it a basic alarm just disconnect the main wiring harness to alarm box- unplug and the car should start. Good luck and thanks for using FIX YA

My 1988 Nissan AC quit working soon after having the compressor & ect replaced. AC Tecnition took the switch box out from under the dash and cleaned it. He also fixed a loose wire in it. He said this cars switch box calcimates and does not make good contact. AC works great.

undo the child locks. These are located on the side of doors.
