Working on a 2005 Buick LaCrosse cxs with the 3.6l. Car won’t start. Won’t turn over or anything. Hooked tech 2 to it and it says fuel security disabled. Have master key. Tried reprogramming but it doesnt...

First make sure the battery is fully charged. Then check for clean battery post connections. Then check all the main fuses located in the plastic box under the hood close to the battery on top of the inner fender. You should have all dash lights if everything check out to this point and it should turn over with the key.

Why doesn't new alternator charge battery?

Some cars have a fuse for the alternator instead of link. The belt is on correct and all connections are tight? What's voltage while running? Year model?

Have 2002 Bonneville, shut car off now have no power, no lights, horn nothing. Can wiggle ignition key, relays start clicking even with ignition off and key removed, will drain battery and battery...

Could be, sounds like a big electrical short somewhere. First check that it didn't kill your battery. Have it tested. If it is old, just replace it- you have to have a fully charged battery to do any checking or testing. Check all your fuses, and it would really be good to know there is power to the fuse. All of the maxi fuses are hot at all times. Use a simple test light to check they have power-one will feed the ignition switch and one or two others are for the head lights and lighting. You can check every fuse on the car, both underhood and inside the car at those fuse panels -with key on EVERY fuse on the car should have power to it. Just touch the test light probe to the top end of the fuse, that little indent is a test port to check for power. Every fuse has those openings, one at each end. A good fuse will light your testlight at both ends of the fuse. A bad or blown fuse will only light one end of the test light.
You may have lost power right off the battery if nothing works. How warm were those battery terminals? A poor connection will create a lot of heat, but that would likely be hot
Start with a fresh battery, make sure cables and connections are good, make sure the fuses are good and have power, then hit the switch-if it blows something, bad switch or a short in a wire.
Good luck, Don.

Wwrong battery polarity

I don't even want to think about it. You could fry...eggs for breakfast.
Try it with the battery correct. See what happens. If you are'll want to start buying lottery tickets.
Nothing you can do now, anyway, so just try it. If it shorted out quickly, your lucky. Hopefully, a fuse.

I can't get my land rover discovery 1999 to start!I go to turn it over and it acts like it wants to start but it won't.I have replaced the fuel filter,the fuel pump,put a new battery in it,and a start

Sounds like a dead short between the starter and the battery. Check the cables under the hood for anything that has rubbed through.

However, it is more likely to be the control line to the solenoid that is shorting out. Trace that line from the solenoid up to the firewall first, than drop the panel under the steering wheel and look there. Use a multimeter set to ohms with one probe on a solid part of the frame and the other probe to the solenoid wire - there should NOT be any reading. If there is, the wire is earthing out

No pwer at all going to driving light nor the instrument cluster, starter turns but it won't turn on .and on the fuse block some of the fuses have no power running to them .the fuses are still good

Sounds like you have a power drain (small-amperage short) in the wiring going to your instrument cluster. The short has disabled some of your instrument cluster lights, but, since is has high resistance, it has not blown a fuse (since it draws to few amps). Once the current drain has wasted enough amperage, there's not enough left in the battery to start the car.
Phase 1: Interim solution: (1) charge the battery with your battery charger (if you don't have a battery charger, attach the battery with jumper cables to the battery in a running car - its alternator will charge your battery).
(2) pull the fuse(s) to the instrument cluster, thus killing power to the short.
(3) start and use you car without instrument cluster lights until you can move
to phase 2 of your repair. If you're not sure that you've killed power to the short, disconect the battery each time you stop the engine.
Phase 2:
(1) isolate the problem (the short) to one specific fuse, meaning one specific branch circuit in the car.
(2) trace the wiring from the fuse block to the instrument cluster, looking for
burn marks, bare wires (all wires should be insulated), or anything touching
a frame ground. Also look for moisture iintrusion - water can cause these types of high resistance "shorts" - with the symptom that the problem disappears after the water dries up.
(3) correct wiring problem found in step 2, plug in fuse. done
(4) if replacing instrument cluster, use instructions below.

1995-99 Models

See Figure 4
Fig. 4: Common instrument cluster found in 1995-97 "S" series Pick-ups.
(see illustration at end of message)

1. Disconnect the negative battery cable.
2. Remove the sound insulators/trim panels.
3. If necessary for access, unfasten the steering column nuts and if necessary, the bolts at the lower flange, then lower the column for access.
4. Unfasten the instrument cluster bezel screws located at the lower edge of the bezel. If no screws are present, then remove the bezel by pulling it straight out.
5. Unfasten the four screws retaining the instrument cluster to the instrument panel, unplug any necessary cluster electrical connections, then remove the cluster.

To install.
6. Install the cluster to the instrument panel making sure the cluster is firmly seated onto the connector, attach any necessary electrical connections and tighten the cluster fasteners to 17 inch. lbs. (1.9 Nm).
7. Install the instrument cluster panel bezel by snapping it into position, then if equipped, install the screws along the bottom of the bezel.
8. If lowered, re-position the steering column and tighten retaining nuts to 22 ft. lbs. (30 Nm) on 1995 models. On 1996-99 models tighten the nuts to 20 ft. lbs. (27 Nm). If removed, tighten lower flange bolts to 120 inch lbs. (13 Nm).
9. Install the sound insulators/trim panels.
10. Connect the negative battery cable.

I have a 98 rodeo when i go to start it it clicks then nothing turn the key off then on again and it starts now it acts like it dosent have a battery or anything i started to pull thewires of the battery...

Sorry to say that what you started with was probably a simple solution. The scenario of ignition on, turn to start position, get a click and nothing else, then next time it starts OK.... Usually means that there is a simple fault, either with the starter solenoid (A little switch that controls a bigger switch for the starter motor) sticking or failing, or a poor connection of the power lead to the starter motor. If you can get yourself back to taht position, I would suggest that you check the connection on the starter motor and the solenoid.

It soulds like when you started pulling wires off you shorted the starter motor feed to the positive on the battery and caused it to engage the starter motor.

I don't want to sound patronising here, but your description of what happens strongly suggests that you don't really have an understanding of how these things work and you are at risk of making the problem far far worse. If you can't get back to the position where you just have the original problem so you can check for a poor connection or a failed solenoid, I really would call on someone who knows exactly what they're doing.

Turn it my starter?

If there is nothing, you probably have a dead battery-nothing else would cause no crank/lights or accessories unless it was a bad connection at your battery terminals. charge the battery with a battery charger ) a 2 amp charger would take a couple of days, 10 amp about 8 to 10 hours and a 50 amp about 3 hours, but charging slowly is better for the battery)- If you have a voltage meter, chances are your battery is well below 12 volts, and as it sits it should recover somewhat, but probably you will still need to at least charge it. Conventional batteries do not do well with full discharges and it can 'kill' even a fairly new battery in short order, so prepare for the possiblilty that you need to replace it.

My 83 impala will not starr or crank when key is in ignition lights come on on dash but no sounds

It's possible that your battery is low, although the starter will usually click. Turn the headlights on and see how much they dim when you turn the key to start. They should dim a little but come right back when you release the key. If they do the battery is likely not the problem. If they don't charge up the battery and try it again.
Make sure your battery terminals are clean, shiny and tight. If ou can turn them on the post, tighten them a little more so they don't turn. Try grounding the starter case to the frame with a screwdriver and turn the key. If it starts, clean the grounds between the battery and engine and between the engine and body. They should be on the alternaror bracket and at the rear of the engine to the firewall. You want bare shiny metal contact points. You may have to run another ground from the battery to the frame. If you do attach it to the stud on the front of the starter case. Use the same guage as the battery cable.
If you still have nothing, try shorting out the solenoid. If it starts, the solenoid needs to be replaced. If not, disconnect the battery and clean up the cables on the main terminal. It's a good idea to replace the solenois and starter as a unit, saves taking it apart twice in a short period of time.
If you still have nothing, there are 2 fusible links down by the starter. One is for the engine and the other is for the body. They do go bad over time. I just cut them out and spliced the wires back together, but it you want to replace them instead, the fusible link is 2 wire sizes smaller than the wire they are in. Use heat shrink tube to seal the joint and cover that with electrical tape. You have to keep water out. I've never bothered to sort out which link goes where, I just replaced both at the same time. You have to unwrap a lot of wiring to sort that out. Hope this helps.
