Why would a fuel pump run continously when the key is in the on position does this indicate a bad pump relay or fuel line?
An electric fuel pump is supposed to run as long as the circuit is on, which putting the key on does. In fact, the fuel system operates under some pressure and in order to start when you turn the key to start position, the fuel pump must go on and begin the flow/pressure up before the engine actually needs the gas. Frequently in especially older cars or those with some part of the fuel system failing (especially when it leaks/loses pressure quickly), it is common that the key must be turned to on for a longer moment so the system can purge & establish itself before starting.

Can the position - time graph have a negative slope?
Yes, a position-time graph can have a negative slope. This would indicate that the object is moving in the negative direction with respect to the chosen reference point.

Why would a relay cause the air conditioner to not work in your 1999 escort zx2?
On vehicles that are equipped with a RELAY for the A/C system. You will find that if you have a faulty RELAY that the A/C sytem will not work. This is because the relay acts as a switch to supply power to the sytem when the switch is engaged. When one goes bad it could be broked, burt or in most cases stuck in the closed position.
Why would a 95 Geo Tracker not have spark and have a buzzing sound coming from the fuel pump relay?
A 1995 Geo Tracker may not have spark due to issues such as a faulty ignition coil, a defective crankshaft position sensor, or a problem with the ignition control module. The buzzing sound from the fuel pump relay could indicate that the relay is malfunctioning or that there is an electrical issue, such as a short circuit or poor ground connection, affecting the relay's operation. It's important to check both the ignition and fuel delivery systems to diagnose the issue accurately. Additionally, a weak battery or poor connections could also contribute to these problems.
