I got a b1318 low batt voltage code on a 08 ford escape. When turning the key the car won't crank or start. Usually takes sometime before it does. All the lights work and the battery alt and starter are good

Looks like a part faulty battery with some faulty cells. Battery needs to be changed. Still get the battery checked from a battery shop

B1318 we can break it down. 08 ford escape

B is for body or body control module
1318 is a code for low battery voltage. A good charged battery will read 12.6 volts running with a good alternator 14.8 volts.

SOURCE: 2000 ford windstar won't crank over,but pats keys good, and batt.

First thing I would check is to see if you have power at the trigger wire of the starter motor while someone is trying to start the vehicle for you. It will be a Yellow with a light blue trace. If you do then I would check to see if the main battery cable has power to it all the time when someone is trying to crank it. If it does then I would hold a test light on the case of the starter motor and have someone try to crank it. Make sure that the ground you use for this test is on the negative battery terminal not just anywhere on the car. If the test light lights while you are cranking it then you have a bad ground. Hook up a set of jumper cables from the battery negative terminal and clamp it directly on to your starter motor and see if it starts. If you check it and the test light doesn't light up and all the other checks are good then your starter motor has failed. If one of the other tests has failed then you have a starter relay problem or something else. let me know what you find out.

SOURCE: 2004 F-250, 5.4l gas. Won't start or even crank.

are you referring to the starter relay on the firewall? the voltage should drop to 0 when measuring across the signal path because the connection is made, essentially making it a piece of wire and there is no difference in potential between the two points. is there 12v to the starter motor? is the starter solenoid (located on the starter) receiving 12v? check fuses and fusible links. disconnect hot leads from the starter. remove the starter, and supply 12v directly to the motor. does the pinon gear extend and spin? starter.

SOURCE: 06 pontiac grand prix wont start no clicking when you turn the key over even jump starting the battery, has dash lights & radio & parking lights. battery tested good. put a used starter & altinator on

Used parts such as starters and altinators don't last. It might **** but it sounds like you need to buy a new starter,altinator, and battery. Or just start with buying one at a time.

Testimonial: "kellertech1?? i tried something new.. my batt. was dead after sitting for 5hrs so i jumped it & later unhooked the batt. & hooked the batt. back up next day & car started ok kinda a weak start but started. so can a starter drain a batt or where should i look for a short or could this be a weak batt. that tested good but 2 weak 2 start the car."

SOURCE: My 2004 F250 won't start. The battery is good, all gauges work etc... When you turn the key the starter won't even click

more then likely its a bad starter. or the cable to starter.

SOURCE: Hi, have a toyota avalon, tried starting the car , it won't start, but then the starter engaged and won't turn off evenwithout the key, disconnected the battery and it stopped , when the batte

It sounds like you have a bad actuator. This is attached to the starter and has a solonoid that pushes the starter motor gears into the engine gear. If the solonoid is faulty this may happen. Also check alignment of the same.

According to this charging system isn't working correctly ! This is a computer controlled charging system .
Principles of Operation
The powertrain control module (PCM) controlled charging system determines the optimal voltage setpoint for the charging system and communicates this information to the voltage regulator. This system is unique in that it has 2 unidirectional communication lines between the PCM and the generator/regulator. Both of these communication lines are pulse-width modulated (PWM). The generator communication (GEN COM) line communicates the desired setpoint from the PCM to the voltage regulator. The generator monitor (GEN MON) line communicates the generator load and error conditions to the PCM. The third pin on the voltage regulator, the A circuit pin, is a dedicated battery voltage sense line.
The charging system voltage is controlled by the PCM. The generator charges the battery and at the same time supplies power for all of the electrical loads that are required. The battery is more effectively charged with a higher voltage when the battery is cold and a lower voltage when the battery is warm. The PCM is able to adjust the charging voltage according to the battery temperature by using a signal from the intake air temperature (IAT) sensor. This means the voltage setpoint is calculated by the PCM and communicated to the regulator by a communication link.
The PCM simultaneously controls and monitors the output of the generator. When the current consumption is high or the battery is discharged (the PCM recognizes this and increases the output of the generator to accommodate), the system is also able to increase the idle speed to increase the charge.
To minimize the engine drag when starting the engine, the PCM does not allow the generator to produce any output until the engine has started. The PCM then progressively increases the output of the generator.
The PCM turns the charging system warning indicator off after the engine is started and illuminates it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The charging system warning indicator is also illuminated by the PCM whenever the key is ON with the engine OFF.
This is a System 4 charging system, which uses the GEN MON and GEN COM lines to control and monitor the charging system through the PCM. System 4 charging systems are virtually identical in design and therefore, share the same diagnostics. The circuit numbers and colors may be different, but the functions are the same.

Starting problem

HI,
Sounds like a battery or alternator.
This should still be under warranty. I'd take it to the dealer. Otherwise, have the battery and alternator checked out (usually auto parts stores can do it for free).

1994 E150 van ford no alt power have changed the alt. charged the batt

There is a fuse or fuseable link between the alt and battery, and the alt gets a signal from the key to activate the voltage regulator.
I would check for batt voltage at the alternator and you may need a wiring diagram to check for key voltage.

Ford mustang gt 2005 dtc codes

B1318 are related to low battery voltage .
B1202 is fuel sender circuit open.
P0463 is fuel level sensor circuit, (high input.)
If your gauge appears to be working o.k. all I would do for now is double check my voltage at battery with engine off & running, to make sure all is good there, erase codes & start fresh. The cheap way to erase is to remove neg (-) cable form battery for about 5 min., or more & then reconnect. You eill lose your memory on radio stations & have to re-set them though, otherwise have someone hook-up scan tool to erase them. Is vehicle starting & running o.k. at this time?
