Start with the basics, and work your way up, Last tune up was? Wires plugs ALL filters? If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!

Sorry I guess I failed to state the obvious. The starter won't even turn over at all. But it is getting juice to it.

Electrical problem
2002 Dodge Caravan 6 cyl Two Wheel Drive Automatic 147000 miles

The problem is simple. Turn the key to √ √ √ start√ √ √ and nothing happens but the starter relay comes on.

The van has been driving normal for 3 months now. I had a new PCM and Map sensor installed three months ago. No signs of problems at all. The wife drove it home, parked it for 3 or 4 days and this happened.

One problem exists with the key off.
1. The steering wheel does not lock in the park position. I don√ √ √ t know how long this has been the case.

This is what I have with the key in the on position.
1. All dash lights are on as normal.
2. I can hear the fuel pump coming on and hum.
3. I can hear the injectors (or something in the immediate area) click and hum.
4. All other controls work. Ex. Heater, radio, lights, and even the back up lights in reverse.
5. The gearshift shows it in park and it switches through the gears correctly. (Yes, I have tried starting in neutral. Lol)

Here are the parts that I have checked and tested to be good.
1. Starter (new and tested)
2. Battery (new and trickle charged 12.65 volts)
3. All relays and all fuses in the relay box (metered with power and off)
4. Voltages are present at the starter and ground is good on the battery.
5. The control wire from the starter to the relay ohms out good.
6. All connections have been cleaned and tests good.
7. The PCM has worked fine for three months. It√ √ √ s from AutoZone and had been flashed and coded with my VIN. (Don√ √ √ t know if it is bad or good now.)

The neutral positioning switch is incased in the tranny (non-removable) and is a 6 (I think) pole plug. Hanes book doesn√ √ √ t even cover this type of switch. All others are removable 3 pole switches.

I have no engine codes when I try the key method. (On, off, on, off, on)

I tried a completely separate circuit/switch for the starter. With the key both in the on position and start position, in neutral and park. It cranked the engine but no spark was present to the plugs.

One thing to note, when I try to start with the key as normal, the radio shuts off when the key is in the start position.

I have almost totally given up. What next.

All symptoms and things checked like this person.
And same results except mine is a 2003 and the steering wheel still locks when key is off no codes no check engine light on

This could be the ignition switch, not the key(cylinder) but the plastic part the harness plugs into, or your computer(PCM), Test the switch like this:
IGNITION SWITCH 1. Remove ignition switch. See IGNITION SWITCH & LOCK CYLINDER under REMOVAL & INSTALLATION. Check continuity between ignition switch terminals No. 3 and 5 with ignition switch in START and RUN positions. See Fig. 3 . If continuity exists, go to next step. If continuity does not exist, replace ignition switch. 2. Check continuity between ignition switch terminals No. 4 and 5 with ignition switch in START position. If continuity exists, go to next step. If continuity does not exist, replace ignition switch. 3. Ignition switch sends multiplexed commands to Body Control Module (BCM). Use scan tool to diagnose affected system(s). For diagnosis and repair, see BODY CONTROL MODULES - CARAVAN, TOWN & COUNTRY, & VOYAGER article. For ignition switch circuit function, see IGNITION SWITCH CIRCUIT FUNCTIONS table.

K so funny thing. I did that test and pins 4&5 didnt have continuity so I replaced the ignition switch. After replacing the switch I started the vehicle and it immediately died and now im right back to where I was with a no start issue. This is frustrating.

After cycling the key, does the check engine light flash? If yes it's flashing 2 digit codes, let me know and I'll explain how to read them.

When you replaced the ignition switch, did you replace the key as well? If yes, it will need to be programmed. Running for a few seconds and dying is a symptom of a security module issue. It would have to be scanned with a scan tool that reads B and U codes. Generic scanner dont do this.
