Do you have a fuse box under the hood on the drivers side fenderwell ?

You need to attach a pressure gauge to the schrader valve and measure the fuel pressure with the key on and also while running. You need to see about 40 lbs in both cases.

Most are at the starter solenoid on the same post that the battery (+) cable hooks to.

if the water pump is bad, it will leak from the weep hole on bottom of pump. unless the bearings seize up on pump and will not turn. you will see coolant running from bottom.

check to make sure pet is tight; tighten all hoses. Anything more and you will have to creep under and see where it is leaking. Hopefully not serious.

switch is located on top of the steering column, just below the mounting bracket. check to see if solenoid is getting voltage when in the crank position 1st, than go after the switch.

Does the engine spin over and not start? Or turn the key and nothing happens?
New spark plugs and wires won't have anything to do with the starter and battery keeping the engine from spinning when you turn the key.
Need more specific explanation. Thanks,

It's the fuel pump.

remove your coil and take it down to most any part dealer and they can test it. from there check coil wires, plug wire,cap and rotor(if present) and ignition module.

Depends on your experience,the tools you have& how much patience you have.Everyone will see any automotive repairfrom a different perspective

replace pump or remove it and replace with idler

Power goes from the fuse to the function select switch, then to the blower motor. The fan switch and the resistor is the ground circuit for the blower.

Fuel level sending unit. I hope it's not, but ya..... it's inside the fuel tank. Also called the float level. Not an easy task unless you are ready to drop the fuel tank at home. Some had a small access hole under the back seat so you could get to it easier, but it's not that easy to get the back seat out, and harder to get it back in. Hope this helps.
