[RESOLVED] Car won't start after short drive.

[Bubbs Malone]

I tend to run errands on the weekends, so this is when I realized something was wrong.
I can drive ten or fifteen minutes, park the car and try to start it. The car cranks strong, but won't start. After twenty or thirty minutes sitting, it will start again. The Check Engine light goes on and it will throw CEL PO351 and PO352 for coil pack malfunction.

I changed the Coil Pack and it continues to do the same thing. I read the forums and did some google searches as well. I have some things to check over the weekend, but thought I would throw this out to everyone, in case I'm missing something obvious, thanks for any help.

Things to check:
-Fuses
-ECU
-Shorted wires
-Camshaft position sensor

Change your wires maybe? Oh and check all your fuses first.
Check your plugs too.

on my NT back in the day i had this same problem it turned out to be the battery cables were corroded inside and the terminals.

defff gotta me your CMP cam position sensor when they heat up after normal operation they dont read right and you gotta wait till it cools down you should just replace all your old sensors it should take care of the problem

My car does something like this. It runs or 20-30 min.
I replace the cam sensor, just to figure out its the crank position sensor.
Make sure your getting good connection to all wires in that area.

Great input, it sounds like I'm going in the right direction. I picked up some plugs and wires today, I'll start with that and definately check all of the connectors and terminals.

Update:
I changed the plugs and wires, checked connectors and tightened the battery terminals. I took a couple of short trips across town, the car is starting up fine. I'll see how it does Monday when I head back to work.

The plugs and wires seemed to have solved the problem. The strange part is, the car was idling a little rough, that's it.

After running some errands and commute traffic for a couple of days after changing plugs and wires, the car seems fine. I'm getting less vibration at higher speeds as well.
