1994 geo metro does not start checked fuel pump and injector relays checked all fuses there is no voltage at check point under back seat for fuel pump when car is cranked what do you check now?

when you turn on the ignition before you crank you should hear a buzz for about 3-5 seconds and a click at the relay under the hood. If that happens your pump is working. normally when you crank the engine the fuel pump is not running until the engine starts If there is power coming out of the fuel pump relay pink wire, but the power does not get to the pink wire under the rear seat, you will have to start tracing out the wire in between the two to find the open.

What condition the relays should be use in power voltage?
Inorder to achieve the impedance maching ....
What are the three kinds of switching mechanism used in low voltage?
Transistors, relays, and triacs.
What makes relays click repeatedly when engine is trying to start but will not?
Low voltage, either caused by low system voltage, or faulty wiring or connection.
Why current transformers are required in protective relaying scheme?
Current transformers (CTs) are used to monitor the current (or lack of) in high-voltage systems, and their secondary outputs controls the behaviour of protection-system relays. The CTs (1) reduce the current to values that match the current ratings of the protective relays, and (2) electrically-isolate the relays from the high-voltage system.
1996 Chrysler sebring have checked all fuses and relays and still no brake lights is there an in-line fuse you are missing?
Assuming you have checked the bulbs, check the brake light switch.

Do relays use high voltage to control low currant circuits?
Low voltage to operate relay controlling high CURRENT circuits (currant is a dried fruit).
What would be wrong with a 92 tracker pumping way too much fuel through the injector I replaced the injector-ecm-fuelpump relays-and pressure regulator and yet it still dumps excess fueL AT injeCTOR?
i would check the wires, you might have a short to power which would keep the injectors open all the time.
1992 Geo Tracker got spark only runs if you spray carb cleaner then quits has new fuel injector relays computer checked out fine HELP?
Bad fuel pump? or relay? In a '92 the chances are good that the capacators inthe ecm are gone,the early {8 valve}trackers/sidekicks were famous for bad caps.

95 toyoya truck fuel pump relays?
I am unaware of a relay only a "Fuel Pump Resistor". This is used to reduce voltage.
