After couple weeks happen again. Ignition switch was replaced. Was okay one week. Now its sitting in garage and no start at all. Not even making any click sound. Will tow tomorrow. I don't know what's wrong.
Any one knows. please help

I have the same problem with my 07 too. The car does not "think" it is in park and will not turn over. I put the car in drive and then back into park and the car starts.

I had the car into the Chrysler dealership at least 20 times over a 5 year period for this problem and they could never "fix" the issue.

This is not a solution by any means however, maybe enough for a mechanic to fix the situation.

Hi
I have finally found the problem. 07pacifica does not start while turning the key in starting position. We replaced starter and ignition switch. Still had issue. Finally we replaced integration power module. Which is the fuse box in engine area, cost me $800 approx. And it fix my starting problem. This part is superseded. And damn dealer can't diagnosed.
Replace that and its easy to install new one. After installing the there is a 40amp fuse which needs to be turned 180 degree I think its called iow fuse or let parts department know which fuse needs to be turned to 180 degree
Thanks and good luck.

Hey"zbabar", you're talking about fuse #3, IOD.

Hi
Yes that is no # 3 IOD. I believe its 40amp.
just get new fuse box. all fuses come with it. You don't have to swap over anything except IOD fuse. that fuse needs to be turn over 180 deg. because its part of PDI at the dealer. and also the part is superseded.
thanks

Hey "zbabar" have you had any problems since you replaced the IPM? Where you guys having any other problems like the car stalling?

Well so far it runs normal. First of all check fuel pressure. Some times fuel pump get weaker and causing stall.
And also check if there is any codes.
Clean mass air flow sensor.
Thanks

No codes, no check engine light and I also have the wonderful no start issue :mad:

have you had any issue with the no start/start since you changed the fuse box?
