Engine stalls when turn on headlights


You probably have a ground issue , looking at a wiring diagram or ground distribution diagram to see if these share a commom ground point or share power from same fuse,https://www.youtube.com/watch?v=WoN1nou5t1Q&t=224s circuit with a high resistance problem . Do you know how to test automotive electrical circuits with a DMM - digital multi-meter , how to read an use a wiring diagram to pin point test spots in a circuit . Free wiring diagrams at http://www.bbbind.com/free_tsb.html . Check out these videos on voltage drop testing an basic electrical testing . This is the way to find electrical problems .

On the positive side of battery Julie is where your fusible links are,you say it's getting hot,I would follow all wires,look for burnt or swollen wires,they go to starter.Here's a wiring diagram,it shows that you have 3 fusible links leaving your positive battery,they need looking at,check all wiring in line with positive battery cable.Look at diagram number 25,enlarge to see.

Won't start


How about corroded battery cables (internal)

Fusible Link wiring corroded & open circuit,does
everything electrical work except the starting circuit?

Turn key & have power to starter solenoid ?
Neutral Switch !
Ignition Switch !

Tough to guess without wiring diagrams,
to see where to start testing

Can't fix what you don't know you have

1993 BMW E36 325i odometer and clock won't turn off and kills my battery


fit a battery isolator inside the car under the dash on the battery earth is the cheapest soloution.Or a wiring diagram to trace the wires to locate the fault which i suspect could be on the radio wiring where 2 feeds are used one a permanant 12v feed and one a switchable feed via ignition switch causing a backfeed if done wrong .

It won't turn over


Try this procedure:
Check the battery like this:
Turn on the headlights, then try to start the car.
If the headlights do not dim or go out, then the battery is likely ok.
Check that the battery cable plus post, goes to the starter, Minus post to a good ground, like the engine.
If wiring is ok, then look at the starter solenoid for a good connection, and proper voltage at the starter.
Problem is most likely the Solenoid's bendix gear or starting relay, Have someone bang on the starter while you try to start the car. This usually works by dislodging the bendix gear..
Hope this helps.

2000 gmc sirra won't start


Well stop looking on forums , most of those people don't have a clue ! Looking at a wiring diagram of the starting electrical circuit for your vehicle ,then testing for B+ voltage an good grounds where they should be is how to find and fix the problem , not guessing an listing to other people on forums . Something that fixes there problem was just lucky guess. By you saying it won't crank i take that to mean that when you turn the key to the start position nothing happens ? Is this correct ? A lot of people get that mixed up with the vehicle won't start a run . Do you know what a wiring diagram is ? What a DVOM -digital volt ohmmeter is ? How to use them for testing a electrical circuit .
What size engine does it have ? Is it a 4X4 ? Manual or automatic transmission ?
Free wiring diagrams here http://www.bbbind.com/free_tsb.html
Enter your vehicle info. year , make , model and engine size. Under system click on engine ,then under subsystem click starting Click the search button then the blue link. Look at the wiring diagram , a lot of thing's involved . Ignition switch ,park neutral safety switch if it has a automatic transmission , clutch pedal position switch for manual trans , plus the starter motor relay ,starter motor . This is how professional automotive tech's find and fix electrical problems , it takes year's of training to get good . Plus thing's change all the time .

No feed to fuel pump


Model Year is always good to know, just to help determine age of the vehicle.

If this bike has sat all winter, you may need to clean connections at the fuse box or where they are exposed. The loss of a ground connection is just as bad as losing the + connection. It takes both to complete the circuit. Grease on clean exposed connections seals them somewhat.

Make sure you have a fully charged battery. Modern electronics require minimum voltage amounts or won't function.

You could also have a fuse blown, or a switch (Ignition) that isn't working properly. I would suggest that you test voltage from the Battery, through the fuses, any fusible links that may appear to still be good, but may have burned through inside of the wiring harness. Verifying your voltage all the way through the switch and to that wiring is really the only way to find this problem.

This would also involve testing any sensors that have input/output signals that can turn on/off, the module & fuel supply.

A nice digital multimeter will prevent burning anything out, but you should also consult the wiring diagram & service manual to make sure you don't hook up to anything extra-sensitive and cause it to malfunction. LED probes are usually safe for testing those.

If animals had access while in storage, you'll identify any broken or semi eaten wiring & repair during your inspection.
Good luck!

I have a 1992 Nissan that somebody cut into the wires going to the battery now I've tried to wire it back together but now I'm getting no pulsating ground and truck won't start but will run if...


This truck will not run else you pour gas into throtle body.
Okay, you know its fuel, you are saying that the wires to battery were cut.

Before going into the wiring did you use a noid light to see if there is a pulse at injectors? or are you thinking its that due to the fuel not getting to engine?
I would make sure the fuelpump is operating and suppling enough fuel pressure and test the injectors for power and ground, a noid light would be a great cheap tool to test.

If you have already tested and there is no pluse then check the wiring but take note, check wiring to distributor as your pulse will come from that and the computer.

Look for any blown fuses or power wires that are missing. i will enclose a few wiring diagram that i think will help you in your testing . also here is the injector wiring diagram you requested for the 1992 nissan pick-up.

Have a good day and let me know if there is anything else you may need .3_4_2012_12_50_55_pm.gif3_4_2012_12_51_45_pm.gif3_4_2012_1_09_53_pm.gif

Honda Pilot 2003 won't start. batter is good. seems to be an electrical issue because starter won't turn at all and there are strange clicking noises when key is turned


I would be re-checking the battery. Make sure that when you have it tested they do a "load test". Sometimes a battery can seem good, but be bad when there is a large load placed on it. This test will reveal if that is the case. It could also be a starter problem, and it is possible (but unlikely) that it is a wiring problem.
