What is the blue wire that plugs into the fuel pump on a 2000 Lincoln town car with a 4.6 motor

At the fuel pump, pink with lite blue tracer is voltage.
I looked at the fuel pump relay , there are two lite blue wires with orange tracer. I divide the relay into two sides, load side, has the arm with arrow head, that lite blue wire is voltage, you can see the fuse. The control side of relay is that coil looking symbol, that lite blue wire is ground controlled by computer.

My car is not starting and thinking it's the fuel pump. Try jumping it and still not go. Alternator and starter are fine. So I've removed the fuel pump from the tank. There's a white connector that...

Four wires the the sender unit. One will have 12 volts all the time with key on. This is the fuel gauge. One will have power for 2 seconds when the key is turned on. This is the fuel pump. Two of them will have a constant ground. Grounds will be black, black with a colored stripe on it, or have a black stripe. Check the harness plug plug for voltage, again it only last for 2 seconds. If you have voltage at the wire. replace the pump. If not, probe the wire about 3 inches back from the plug, check for voltage again. If you have voltage there repair or replace the plug. Most wires break right behind the harness plug.

Not sure what you are using as a ground when checking voltage. If you check at the connector you should have 12 volts at the blue wire with the red stripe (red prong on volt meter) and you can check putting the ground/black prong on your volt meter on either one of the black wires on the connector. When turning the key just to the on position you\'re only going to get full power for about 2 seconds unless you\'re turning the engine over. If you\'re not getting full voltage try putting the black prong (leaving the red one from meter on the terminal that has the blue wire with the red stripe) using a good ground on the body of the vehicle (the black prong from meter). Now if you\'re getting the voltage you need then you need to trace the black wire(s) to where they are grounded out on the vehicle and clean/tighten and repair the ground as well as making sure you are getting zero continuity from where the ground is on the body to the connector at the fuel pump. A bad ground will cause weak power. These are also the 2 wires you need to apply direct power (on the pump side of the connector) in order to check the pump as you asked. Since there are 2 black wires at the connector, if you have direct power to the blue and red wire and put your ground on one of the black wires and it doesn\'t run, than try using the other black wire (or where it would be on the terminal of the connector...pump side) at the connector because that would mean you are testing the wrong ground wire for the pump itself. If your ground is good down there and it turns on when applying direct power than it could be a number of things but the 2 most common would be the fuel pump relay or the air flow meter/sensor. Start with check power and ground and direct powerfirst. If the pump is working when putting direct power and your grounds are good then further testing needs to be done of course. I\'ll be happy to help you with further testing if needed like checking the relay and/or air flow meter. You will need an ohm meter for further testing. I hope I was detailed enough for you to understand the testing needed at this point and I hope I was able to help

Fuse for Mitsubishi fuel pump

It is critically important for turbocharged models that the fuel pump receive the maximum amount of voltage available from the charging and wiring system. The alternator will try to maintain about 13.5 volts into the system. Resistive losses along the current path to the pump will reduce the voltage at the pump to something less than 13.5. If there are less than 12 volts at the pump, the amount of fuel flowing may be much less than expected and perhaps enough less to create lean air-fuel mixtures under heavy boost.

The instructions below show you how to bypass the resistor and relay that the turbocharged 3S models use to reduce voltage to the pump at idle. Please read through the instructions and look at the pictures before attempting this procedure. Before I did this relay/resistor bypass I measured the voltage at the pump using the method shown on my web page 2-fuelpumpvoltage.htm. At idle the pump was receiving about 6.7 to 7.0 volts. I saw from 10.6 to 10.8 volts as boost began to build and then watched that number drop to 10.2 to 10.3 volts as boost hit 15 psi or so and RPM approached redline. After performing the relay/resistor bypass I remeasured the voltage at the fuel pump with the following results.

Cold idle: 11 volts
Warm idle: ~10.6 volts
Warm idle after radiator fan kicked in: 10.35 - 10.55 volts
Acceleration and boost: ~10.5 volts

1987 Jeep Cherokee-4.0L I6 auto tranny 4WD. Fuel pump will engage if straight wired but not if plugged in, engine will crank but not turn over, checked all relays & relaced battery cables &...

If you turn on the key and you do not hear the pump in the tank running for two secounds ( the same time your warning lights on your dash light up and goes off) then 1 you need to replace the pump or 2 it has low voltage to the pump or 3 both. I just repaired a 1987 pioneer what you need to know is the pump requires 12v at the pump, however OEM has placed an inline ballast resistor located on the driver side front engine compartment near the hood latch that is made of white ceramic with two connection both wires are orange with a black stripe. A. Check the voltage on both sides of the resistor 12v in 12v out use a volt meater - to battery + to resister if no voltes check the relay the passenger side of the engine compartment ( there is 4 relays from front to back it is no. 2 from the battery) looks like a small blue box newer relays are black, if they do not click when the key is on then your CPU may be bad or fusible link is bad If you have voltage to the resister and you have 12v in and less than 12v out your next test will be at the rear connector to the pump, three wires close to the fuel filter using a volt meater check the black wire with the orange / black stripe if voltage is less than the voltage out of your resistor then there is a bad wire in the system and a new wire is required. confirm this by jumping the battery to the pump wire black to- and orange to + the pump should run. Note. running the pump with lower than 12v will damage the pump and cause it to fail! If the pump works you can check the fuel pressure on the fuel rail, remove the cap to epose the shearder valve (looks like the valve on your tires) depress the valve stem and fuel should come out, caution fuel is under pressure have a rag under the valve to catch the fuel, if low pressure the pump is bad and/or filter is plugged Replace filter first recheck this test then replace pump and recheck. Note!!! when the pump is out of the tank recheck the voltage at the pump this will show true voltage at the last connector it needs to be 12 volts! Reconnect the pump wire the stock wire and check, on the pioneer I worked on was 4 volts so I rewired it to a new battery source using the orange /black strip wire that had 12v in to resistor as a trip wire for a 65 amp power relay. The owner noted an increase in overal performance " it now has more power now" hope this helps

I need the EXACT location of the fuel pump location (relay) I found the relays under the hood but the writing on the cover is all worn off

the fuel pump relay has 1 big red wire with a stripe on it and a small gray wire and 2 blk wires one with a stripe on it and possibly a small orange wire all going to the plug on the bottom of the relay

Where is the fuel pump relay on a 2002 nissan sentra 1.8

The fuel pump relay is behind the kick panel on the drivers side. The wire colors coming out of the relay should be Black w/ Red stripe, Black w/ White stripe, Black w/ Yellow stripe and Black w/ Purple stripe.

1995 silverrado fuel pump relay

4.5 volts , that's not right . Resistance in the circuit . before the relay ! Do voltage drop testing , not ohms . That should stay at vehicle (battery voltage ) It should go low on the other side of the circuit . Watch this video on voltage drop . Voltage is not being pulled low , it should not not drop voltage till it goes through the relay coil , on the ground side .You have high resistance in that green with white stripe wire .
