Problems 1 & 2 - Pump/Float assembly.

After 22 years, things get rusty and seize, since there is a double fuel system problem, the most likely culprit is in the tank, and usually after this many years (not always miles), its the pump and float.

As for 3. 22 years of wear, tear and rust. Trace the brake lines and find the wet spots. As the braking system is a sealed system, its quite dangerous to continue to operate a vehicle with some form of puncture or leak, as it can cause air locks and cease functionality of the brakes. There is a good chance that somewhere along the lines there is a worn seal, line or connector that is leaking. Follow the lines from the master cylinder, find the wet spot and replace the connector, seal or line that is worn as needed.

1987 Nissan Maximum gas hand doesn't work & transmission is reading full but it leaks sometimes

There are three fixes possible for the gas gauge....but I would have this troubleshot by a garage:

1. The gas gauge itself does not work anymore. It could have just finally "died". Problem is, you cannot replace just the gauge. It has to be the whole instrument cluster. Having a garage shoot power TO the gauge and then shot the gauge itself will let you know if the gauge assembly is bad.

2. The fuel sending unit is bad. This means the wiring to the gas tank fuel pump/sending unit is bad and does not work. The signal is not being sent to the fuel/gas gauge. This means the fuel pump assembly needs replacing.

3. There is a wire problem somewhere between the gas tank and the dash to the fuel gauge.

The transmission leaking but still reading full just means that there is plenty of transmission fluid in the transmission. The drips or spots you are finding are not enough to "read" low enough. Unless you have a HUGE spot of tranny fluid left on the ground, I would just think about a transmission fluid filter change. This way, a new pan gasket will be installed and fresh fluid filled to the proper level will be accomplished on your car.

1987 Toyota Camry. Idle doesn't drop. Stays very high. No clue why. Also goes through a lot of gas and found out muffler and catalytic converter aren't hooked up. Ideas of where to start?

check your vacume hoses and if iyt has an idle controll valve that is off of the air intake. that should be the only things that would effect it

Vacum leak on vacum booster for brakes

check vacuum hose first and make sure it's seated properly and not leaking.
This vacuum hose, if leaking, will cause engine to run rough or die.

If you are leaking fluid, the problem is most likely the master cylinder leaking.

If the booster itself is bad, it is a very hard job to swap it out as the mounting bolts are far behind your gauges on the firewall.

I hope you have a good booster.

If the brake pedal sinks with light foot pressure but is hard when you stab the pedal the cause is the brake fluid bypassing inside the Master cylinder. Replace and bleed or rebuild the Cylinder.

Okay got a lot so if you can respond by the numbers thanx....... #1.THE EASIEST WAY TO REPLACE HEATER CORE...... #2,GAS SMELL IN THE INTERIOR AND IN THE TRUNK RIGHT NEXT TO THE EMERGENCY FUEL SHUT OFF...

#1 the heater core is in the plastic ducting under the passenger side dash.Its a time consuming job.#2 The shot of fuel button is leaking when the fuel pump pressures up the line to 14psi or the top of the tank leaks when full.#3 Your sending unit may be U/S which is located in the tank and #4 The WD-40 is a dry spray and only last a short time. I would recomend white grease or fluid filum so it would clean and lubercate at the same time.Hope this helps.

1987 Ford Ranger 2.0L idle is very high and wont go down

Sounds like you need W-D40 on all the movable parts of your carb. Also see what is blocking the butterfly to close all the way. Check the high idle linkage and see if it is properly closing all the way on warmup.

I have a ford f250 and the cruise control quit working

If a gas engine, check the switch on top of the brake master cylinder (cruise control deactivation switch) if it is leaking brake fluid it will cause too high of resistance causing the cruise system to think the brakes are being applied. Recall 05S28 applies to this problem. Juming the connector will confirm this.

Gauge stays on empty

If you are referring to the gas gauge, It is one of 3 choices or a combination of them. 1 A bad float in your tank. 2 A faulty sending unit May be in tank or by fuel pump. and 3 loose connection from these to yor dash gauge. Good Luck
