Could use more information but in the mean time I assume you mean if you wiggle the wiring the truck starts? If so tighten all cables leaving the battery at both ends. Also, the battery could have a broken internal battery post. By this I mean it is broken internal to the battery. This requires a new battery.

2010 CRV, just shy of 30,000 miles. Will not start. Has been in the repair shop 4 times in 7 or 8 months. New Alternator, new battery. What is causing this???

has there been any fault codes reported or has anybody bothered reading the fault codes
reasons for not starting include
cam/ crank position sensors--- broken wiring , faulty harness connections, sensor position adjustment incorrect
low fuel pressure --- pressure regulator problem, fuel pump relay problem, fuel pump
immobilizer problems --- fob battery low on charge , problem immobilizer system
ignition control module--- wiring , faulty internal components
gear position switch---park or neural out of adjustment--wiring problems
a battery may be causing the problem--- but check ground points for tight and clean-- if you are saying that occasionally it will not start, it could be a problem starter motor with a bad commutator bar
it has been back for a number of times but the replaced items indicate that the shop is using a replace parts to find the problem rather that a fault code systematic approach to trouble shooting and problem solving
might pay to find an accredited service shop with experience on your make of vehicle

Car wont crank or start up

Try the lights to see if battery is working. Also try starting it in neutral instead of park. This checks the Park/neutral safety switch on the transmission. If it starts in neutral, it may just need the shifter cable adjusted. If not then the switch is bad.If battery is strong, you need to test for a start signal at the starter while in the cranking position. If you have power at the signal wire, and the battery/cables are ok, the starter is out.

I would say that you need to replace the alternator. The car was running on the batteries power. When you drove the car, it ran the battery completely dead.

How many labor hours will it take to install a new alternator in my jeep grand cherokee?

How to Replace an Alternator (DIY Time: 2.5 hours)
Complexity: Moderate

1. Alternator - $151.95

1. Combination Wrench Set
2. Screwdriver
3. Multimeter
4. Serpentine Belt Tool
5. 3/8 in. Drive Ratchet
6. Socket Set

Step 1 Open the hood and locate your vehicle’s alternator.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.
o Tip: Always make sure the struts on the hood can fully support the weight of the hood so that it does not close on you while working. The use of a hood prop can securely hold it in place.

Step 2 Using your digital multi-meter, check the battery voltage. A dead battery will usually have less than 9 volts. This would not be enough power to start most vehicles.

Step 3 To verify that your alternator is bad, make sure your battery is fully charged and can pass a load test.

Step 4 With the good battery installed, connect your digital multi-meter across the battery terminals with the engine turned off. A good battery should read between 12-13 volts.

Step 5 Start your engine and read the digital multi-meter’s output. The voltage should rise near 13.5-14.5 volts.

Step 6 Using an open end wrench, disconnect the battery’s negative cable.
o Tip: When disconnecting battery cables, be sure to always disconnect the negative cable first and do not allow it to come in contact with the negative terminal post while working on the vehicle.
o Tip: Wrap the battery cable with a shop towel and pull it away from the battery terminal.

Step 7 Disconnect the power and ground wires on the back of the alternator paying close attention to where each wire connects. Disconnect the wiring harness connector.
o Tip: Check for a loose wiring harness connector, cracked wire insulation, and corroded terminals. Replacing the wiring harness may be necessary.

Step 8 Loosen the alternator bracket bolts, and alternator adjusting bolts or alternator belt tensioner so that you can remove the alternator drive belt.

Step 9 Using the proper size socket and ratchet, remove the alternator mounting bolts, spacer (if equipped), adjusting bolt, lower pivot bolt (if equipped), and the alternator.

Step 10 Install new alternator.

Step 11 Using the proper size socket and ratchet, loosely install the alternator mounting bolts, spacer (if equipped), adjusting bolt and lower pivot bolt (if equipped).

Step 12 Install the alternator belt.
o Tip: When installing the alternator belt, make sure the alternator belt is fully seated in the groove of the pulleys.

Step 13 Pull the alternator until the alternator belt is tight.

Step 14 Tighten the alternator mounting bolts while gently moving the alternator unit to achieve proper alternator belt tension.

Step 15 Reinstall the power and ground wires to alternator. Install the wiring harness connector.

Step 16 Push down in the middle of the alternator belt to check belt tension. If the alternator belt moves more than a half an inch, it is too loose, adjust the alternator belt to proper tension before proceeding to next step.

Step 17 Now that the alternator belt has been installed and adjusted, reconnect the negative battery cable. Start the engine and check the battery voltage to verify proper alternator charging.

Step 18 Turn off the engine and recheck the alternator belt tension. Readjust the alternator belt tension if needed.

Good luck (remember comment and rated this).

Engine will not start,acts like dead battery

sounds like the neutral safety switch, check it for power on both wires, if no power when key is on and in park or neutral then there is ya problem. also just try putting it in neutral and try starting it, if that is the case then the switch just needs a little adjusting.

Charging system problem

Possible problems: 1.  Used or rebuilt alternator is also bad. 2.  Improper installation.  Wires not reconnected to the alternator. 3.  Open wire on wire harness leading to the alternator. 4.  Improper belt adjustment.  The belt could be too loose. 
If this is not helpful please provide more information and symptoms.  Answer questions like:  Does your car start? Can you jump start and drive the car long distances?  After jump starting the car, is the battery light still on?  Did you have someone check the new battery to ensure it is a good one?  Are you competent enough to do simple repairs such a battery and alternator replacement?  Answering some of these questions may result in a more helpful answer to your problem.
