the p0352 code indicate a coil circuit failure. I found that for my van one of the leads going to the coil pack that is controlled by the pcm was constantly to ground if the battery was connected. This means that the coil never charges and therefore cannot fire the plugs. This is likely due to a capacitor to the coil driver circuit in the pcm failing. I don't recommend removing the resin in the pcm and replacing the cap as this is your vehicle and if you get in an accident because of your fix, you may end up being in a big pickle.
Why it happens is unknown to me, it may be from command starts, as that one wire that goes to your dash from the coil pack seems to be a command start wire. I would recommend going to a junkyard and picking up another coil pack (i got mine from an intrepid), as there may be a failure in that $10 part ($100 from store) even though it passes the resistance test across primary and secondary windings. If you get a new pcm, it is worth replacing.
The likely culprits are: wiring for the coil pack and injectors, as they go across the engine and may melt from heat; Wiring harnness under the battery box as poor maintenance can drip shit on the harness and wreak havoc; PCM coil driver circuit just failing;
Some no spark causes can include: camshaft or crankshaft sensors being faulty or inproper installation (always new paper spacer, always); Voltage supply circuit to these sensors or the output wire being faulty; a messed up flexplate!; grounds being poor; asd relay being faulty; connections in general; spark plug wires!! (secondary circuit uses two spark plug wires to complete the circuit) replace those rear plugs, it is hard, but if you remove the cowl and start taking things apart it gets easier, and if you take the intake phelum off you get "great" access to the plugs in the rear for 3.3 and 3.8L and you also can inspect the wiring to the injectors/coil pack. Just get a new metal gasket for intake phelum replacement.
I had p0352 as a code and after tracing wires, replacing the plugs, checking the plug wires, and jiggling all sorts of things, ended up replacing the coil pack and the pcm (hard to find the pcm for my 3.8L 1996 fwd post nov 95 production date). Threw the junkyard pcm in and started right away. Just be thorough befor you do that, because it can be rare and expensive for the pcm. Match that pcm part number exactly, as parameters matter a lot. Never took it to the dealer because my year is pre crazy carkey days, and the van has been running for a month no problem.
Hope people don't have the struggle MANY others have with this as dealers want to throw parts at it and it has a tendancy to reoccur for many online companions. BE THOROUGH WITH THE WIRES IN QUESTION. Chase them right to the pcm.

It could be your connections to the battery, as the battery seemed fine before i assume, and the removal of the battery may have weakened the cable connections. By boosting, you may have encouraged a better connection. Was the old battery frozen? low specific gravity? corroded connections?
Consider replacing the terminal connections/ cables if you do feel or see failing wires

if you are replacing the belt, get them lined up in the first place! 1st cylinder tdc and all the marks line up, try to find a photo in a chilton or haynes. there may be one on the net
#42 of 227 1993 Plymouth Voyager Ignition Switch Repair?
Feb 24, 2007 (1:23 pm)
I have a 1993 Plymouth Voyager that has a broken ignition switch. The key will not go into the start position. I bought a new key switch and key set just incase I need both.
Inorder to take out the switch, it says to disable the airbag?
I have not been able to find out how to do this. (I am a electronic tech/machine repairman at a large factory, by trade). and have done some major repairs on my cars, but I just can't find out anywhere how to disable the airbag. There is only one on the steering column. I wonder if there is a fuse that must be removed? There are no key switches that I know of.
Any help would be appreciated. I am dead in the water!

I went out and bought a service manual for the van and nothing in there on the air bag system.
Still dead in the water....
#44 of 227 1996 Plymouth Voyager; engine stops while driving
Mar 05, 2007 (9:59 am)
Need help, my voyager's engine stops while I am driving. I have to let it set for about 20-40 minutes and it will start again. It may operate for a couple of months and it occurs again. I have taken it to the mechanic but none of the fixes seems to solve the problem (replaced several sensors and fuel filter 2x)
The problem is so sporadic and never occurs when the mechanic is checking, so I am unable to get it pinpointed. If anyone is having or has had a similar problem please help me, I am at the end of my road with this thing
#45 of 227 Speed Distance Sensor
Mar 10, 2007 (12:33 pm)
I have a 1991 Voyger LE 3.3L that I am having difficulties with. I have changed the SBEC, the TPS, and the coil pack. I also installed a new muffler just a couple weeks back. It seems as when I installed the muffler, the problem occured. The van starts fine, idles fine, and even runs fine until about 15-20 mins drive time. Then it starts bogging down and missing. It starts burning rich and eventually dies. I also have a speed distance senor that is out, has been out for serveal months (4-6 mon). The speed sensor also helps the AIS adjust in idle. Such as, idle picks up when van is traveling. Idle drops and maintains when vehicle is slowing or stopped. Could this be a cause from the catalytic converter. I have run codes, but am not sure if this means that is the porblem with it running or the computer is telling me it is out. The only code that comes up is the speed distance sensor. PLease help. Thank you
#46 of 227 1995 Voyager se/won`t start after driving in 3rd gear at too high speed
Mar 13, 2007 (7:47 pm)
I have a 1995 Plymouth Voyager SE, it will not start. Before the vehicle refused to start the following events came to pass:
The van was driven in 3rd gear at speeds of 70-75 MPH, when the driver realized this he put it into drive and proceeded, the oil pressure gauge was way up and didn`t come down until the van had sit over night. The engine did not get hot. The oil level was checked and was fine, if not dark though. The transmission fluid is still looking pretty clean. The van was driven approx. 500 more miles when it was parked and would not start again. It was making a clunking sound under the hood, NOT a knocking, a clunking. It was jerking as well this was just before stopping and parking...the last time it ran. Do you think it is possible this is a fuel pump issue? A major engine bummer, or the trans is shot? By the way it does turn over, just won`t start.
Thanks for any thought on the matter!

This sounds exactly like my crank sensor issue. I replaced it and the no start / engine shut off problem went away. However - the real issue may be the connector or further up the wiring harness. I cut off the connector and soldered the wires. Been good for a few months now.

I have a 1995 caravan. I had the same problem but I didn`t do anything about it. It seemed to have gone away. But 2 months ago the van hasn`t started and still isn`t. I believe it`s loose wire on fuel pump or bad pump. The problem for me is I can`t get under my van to work on it. I have serious back problems. Also I have a half tank of fuel and no where to put it.
