crank sensor is bad . Where is the crank sensor. Is it off the cam or underneath of the engine?
what makes it scrub when you turn the steering wheel
Meaning how could I check the wiring harness.
When I got ready to start the van I had a bad gase leak around 2 of the injectors. I fixed the leak but when I went back to start it I had no fire to plugs and no gase to the fuel rails. I checked the fuel pump and it works when I hot wire it. I checked all the fuses in the fuse box under the hood. I can,t find anything else that would stop it from firing up. The relays seem to be ok. Where does the fire come from that goes to the coil pack where is it routed from. I have no enorsha switch. I don,t think I have a theft switch. The 2006 looks just as the 2003 I only changed the intake on the top and the fuel pipe that came from one side fuel rail to the other because the fuel rail I have on the o3 has two lines coming off the rail one going back to the tank, and the o6 has only one. On the side of my fuel tube is a fuel regulator and I don,t remeimber one on the o6. Can u help me out?

2005 Chrysler Town and Country LX 3.3 liter engine 190k miles

Check Engine Light (CEL) was on, failed emissions test in Tennessee, O2 sensor showed as the problem.

My mechanic (not the dealership) replaced the O2 sensor. The CEL came on immediately afterward. My mechanic traced the problem to the only thing they could figure which was a bad Engine Control Module/Powertrain Control Module (ECM/PCM) (two different names for the same thing, I think).

I ordered a rebuilt ECM from a reputable company on eBay. My mechanic installed it and the CEL again came on immediately afterward. My mechanic is stumped. I wonder if my original ECM was even bad.

The dealership charges over $90 just to check the ECM and can only check the one that is on the vehicle; not the one that was replaced. The eBay company has a tech support line, and I left three messages on Friday afternoon. I haven't received a response yet.

What else could this be? Thanks in advance!
