i am suggesting you a link from where you will get the the diagrame http://toolsnyou.com/

Its your radiator its leaking you may not see it vapor .Do a pressure check its not holding 14 lbs

You need a set of hvac gages!

Sparkplugs are not the only cause for a misfire... there could be any number of things. - The cause of misfire should be fairly easy to pinpoint if the problem is present all the time. A quick look at the spark plugs can tell a lot. Signs of arcing on ignition coil, distributor cap or rotor can also point to a faulty part. Basics, such as the compression, timing and fuel pressure need to be checked. - A faulty on-plug ignition coil is typically identified by swapping the coils between the cylinders and checking if the misfire moved with the coil or stayed at the same cylinder. If a bad ignition coil is replaced, it's good idea to change all the spark plugs as well. - The engine might need to be checked for vacuum leaks. The short term fuel trim (STFT) and long term fuel trim (LTFT) need to be checked with a scan tool to see if the air/fuel mixture is not too lean. Often a bad mass air flow sensor causes the engine to run lean causing misfire. - Pressure testing of the cooling system might be needed to check for a leaking head gasket. - Valve adjustment may need to be checked, as valves that are out of adjustment can cause misfiring at a cold start, which is, a fairly common issue in Honda engines. - When the misfiring happens only at idle, the EGR valve and purge valve need to be checked, as either one could be stuck open. - Faulty mechanical valve train components like worn camshaft lobes or stretched timing chain can also cause the engine to misfire; they too might need to be inspected carefully. - Sometimes a broken or damaged tooth at the crankshaft or camshaft sensor gear can be the source of misfiring; checking the sensor signal with an oscilloscope can help if crankshaft position sensor or camshaft position sensor are suspected.

There are a total of six fuses that control exterior lights and dash lights. Check all of these Fuses: 10, 21, 3, 7, 13, 33 Does the high mount stop light work when you apply the brakes?

check for a problem neutral switch and wires may find that switch is loose and grounding out the wire connections or plug

the missing tooth will be of no consequence as the rest ot the teeth in contact with the chain will always be correct code p 0306 refers to cylinder 6 misfire detected ====causes ---engine mechanical fault ( could be a loose valve seat insert)---wiring---ignition/ fuel system---injector (blocked tip position it somewhere else and see if the fault moves to the new position)--- ECT/MAF sensor ---ECM a timing chain problem will not show as a particular cylinder as it drives for all cylinders

The alternator isn't charging , check B+ voltage hook-ups on the alternator . The heavy gage wire on the back of the alternator should have B+ voltage , vehicle not running . The fuel pump has nothing to do with it > terminal 3 at the connector should also have B+ voltage , So should terminal 1 . Charge the battery an get the vehicle running , put a volt meter on the battery post's , if there is about 13 to 14 volts running it is not charging !

it would be best and wiser to replace the fuel filter with the filter that is recommended for the vehicle. No sense in having an accident to save a couple of bucks!! I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

I put a new radio in my 99 ford ranger had the same problem discovered there are two fuses

ONLY use the identical item as the original equipment.( Don't waste your time looking at other products). If you use a different unit you will have significant issues.

Can you check for spark at one or more of the plugs ?

Could be the coil pack... I believe it's a single unit on that model ranger

Always check to make sure that there is not a PCM software update due or available. Often, as the vehicle's engine wears, the PCM's Fuel Map software inaccurately compensates for this condition. The fuel mixture grows lean and eventually, the code sets. A vacuum leak is very common. It could be a torn PCV hose, a torn Intake Air Boot, or even a broken seal on the dipstick (the dipstick is a part of the PCV system and if it does not seal, too much unmetered air will enter the engine). Don't rule out a sticking/leaking EGR Valve or leaking EGR or Intake Manifold Gasket. If it is a V6 or V8 engine and the code is only on one side/bank, it could be a defective Intake Manifold Gasket or cracked/leaking manifold.

Should be a fuse or the wiper motor try the fuse first

run fault codes and check for O2 sensor problem and MAP/MAF sensor problems. If it is misfiring then codes for injectors and plugs may also appear
