What is the name of computer that controls the start of the vehicle

Sounds like a bad battery.

Your charging system is not working correctly. Unlike most other vehicles, the alternator in yours does not have a built in regulator circuit. Some troubleshooting must be done to find the defective component. Most of this can be done with the vehicle still assembled.

First, check that you don't have a blown fusible link. In most newer cars, these will be in the underhood fuse panel, and look like giant fuses. If good, you will read very nearly zero volts and zero ohms when measuring between the positive battery terminal and the alternator output terminal. If either measurement doesn't read zero, find the loose connection, bad wire, or blown fusible link.

Next, check the ground connections to the engine, battery, and car body to make sure you don't have a bad wire or connection somewhere. Again, measure voltage and resistance between the negative battery terminal and all associated grounding locations. For a quickie test, you can rig a jumper cable between the battery negative terminal and the alternator case. If there is a spark when you make the connection, you have a bad ground somewhere.

If your battery is well connected to the alternator, the problem may lie in the control circuit. Most Chrysler alternators have two control wires that control the field coil. Some control the battery current and have constant ground supplied, and some have battery voltage applied and control the ground current. To test, disconnect the control connector and measure the voltage of both terminals with the ignition in the "off" and "run" positions. Make a chart of each terminal and its corresponding voltage.

Start the vehicle and measure both terminals again. If the terminals tend to be zero volts, except when the vehicle runs you have voltage on one terminal, you have a system where the computer controls battery voltage. If the terminals tend to be 12 volts when the ignition is on, then one terminal goes low when the engine runs, the computer controls ground current. If the voltages of one terminal change but not the other, this suggests a bad computer.

To do a go/no go test of the alternator unit, you can connect the control pins on the alternator with the control connector disconnected. Simply connect jumper wires to the two control terminals of the alternator. Connect one jumper to a known good ground, leaving the other jumper loose. Connect a voltmeter to the battery terminals or to the output wire on the alternator. Start the vehicle and briefly connect the second jumper wire to the positive battery terminal while watching the voltmeter. While the jumpers are both connected, the battery voltage should rise dramatically.If it doesn't, this suggests a bad alternator.

If all this sounds too complicated or dangerous, a good mechanic can perform a similar diagnosis in under an hour with definite results. Good luck.

You don't jump a running vehicle

You shouldn't jumping any of todays
vehicles,always charge the battery

You did whatever to it

Now you need professional help

it sounds like your alternator may be bad or going bad recharge the battery start the vehicle and check the output of the charging system it should be around 14.4volts

Before u get the answer. How did u hook the battery up. ? Positive to positive. Neg to neg. If u did. Thats ur issue. U made a 12 volt car in to 24 volt. And u fried your computer. If u hooked the van battery positive to positive and van battery neg to dead car frame. Which you should have done. My guess is you blow a fuse. One of the big ones. But from your notes of nothing works no matter how or what battery u use. U fried the vehicle computer and if the paint and body and drive train are in awesome shape id say go buy a new computer and go from there if the car needs more money to get on the road thsn a yrs worth of fuel id say scrap it get a bus pass or drive the van. But just dont offer kids candy at schools vans are so old school .... Good luck

Hello! There is a Technical Service Bulletin; TSB 06-14-10 for this vehicle that addresses water entering the Power Train Control Module (PCM...computer) or Transaxle vent which will cause transmission problems...A fix for this problem is available at your dealership...Your vehicle does have an electronic shift transmission...Which is controlled by the PCM...No individual fuse powers the digital shift circuit...It powers the PCM...If a fuse were blown the vehicle would not start...

ive run into this problem a few times and it also drove me out of my mind,one of the few i worked on was a control module,cold it was okay then when warm it would die when ever it felt like then start when cold, the other few ended up having bad computers, yes the computer its about 80.00 rebulit, try the computer frist, hope this is helpful let me now the results.

sounds like it could be the pressure control valve on the fuel pump not an expensive repair. the pressure drops in the line over night. try priming the filter whilst the engine is being cranked. the control valve is held on by 3 torx screws on the end of the pump.

Possible dead cell in battery, most likely a fault in the charging system. First, Jump Vehicle to get started then remove the Negative cable. If the vehicle dies when you take the jumper cables away or when you disconnect the negative cable your alternator or charging system is faulty. If the vehicle runs without battery connected you have a bad cell in your battery, replace the battery.

It has to have 2 batteries because it is a diesel engine. Diesels use compression to fire the combustion mixture instead of a spark plug as a gasoline engine does. It has glow plugs that heat the mixture up before starting to help promote this and it has probably twice the compression ratio,therefore it takes alot of amps to start it and that is why you have 2 batteries. No it still only has one solenoid for the starter but it has to use a gear reduction starter instead of a conventional one.
