Can a Failing Fuel Pump Cause a Vapor Lock

Several things can cause a fuel pump to begin to fail, such as electrical problems which can prevent an adequate amount of voltage from flowing through the circuit that supplies power to the fuel pump. The failing fuel pump can then cause other problems that vehicle owners should be aware of.
Vapor Lock
Residual fuel pressure should remain in a vehicles fuel system even if a fuel pump has quit running. However, a leaky fuel pump can allow the system to lose pressure rapidly. In hot temperatures, a vehicle can experience vapor lock if residual fuel pressure gets too low.
Pressure
After checking a fuel pumps pressure specifications, a test can then be performed to compare that with the current pressure being produced by the pump. A pressure reading that isnt high enough often indicates a weak and failing fuel pump.
Tests
There are several types of test that can be performed on a fuel pump to see if its failing, such as a dead pressure test which reveals the total output pressure of the fuel pump. Another test is called a fuel volume test which is helpful in making sure the fuel pump is supplying enough fuel to meet the engines needs.

How to Remove the Ignition Key Lock From a Datsun 280Z
The Datsun 280Z was a sportscar made in the late 1970s. It was later replaced with the Nissan 280z after the Nissan automobile company purchased Datsun. It is the predecessor to todays Nissan 370Z. One of the security features of the 280Z was the ability to lock the steering column and ignition key while the vehicle was parked. This acted as a deterrent to would-be car thieves. It can be frustrating to remove the ignition key lock from the 280Z unless you understand how to turn the steering wheel and ignition key a certain way. Fortunately, you can learn how to do this in a few easy steps.
Instructions
- 1
Put the vehicle in park. If you have a manual transmission, you can skip this step and go on to Step 2 below.
2Press the cars brake with your foot and hold it there. If you have not already done so, put the 280Zs key in the ignition.
3Hold the steering wheel of the car firmly with your left hand and grip the ignition key with your right hand. While turning the steering wheel quickly left and right, simultaneously turn the ignition key as if you are starting the car. The turning of the ignition key coupled with the swiveling of the steering wheel will cause the ignition key lock to release.
