help please my wife has an 05 crossfire that will not start. we had to have it towed home the other day. it has done this before and i changed the the pcm and it fixed the problem. so now the radio works windows etc but i will not crank at all no starter engagement. so now im wondering if the rcm went bad again although i did resolder the old one and still nothing. so im thinking maybe the crank sensor or ???? also can anyone tell how to check the crank sensor with basic electrical tools. thanks for the help

 

check fuse # 37 --no start. start/stop, but radio, windows, seats, locks, and spoiler works.

 

where are you located in Florida? if in SW Florida i might be able to help with scanning it for you to get you going in the right direction.

 

How old is your battery?

 

Many times the relays in the RCM wear out, it is not always the solder joints. Either send it to tighend or buy a replacement for about 130.00. An inexpensive place to start.

 

thx will do

 

maybe 2 yrs old

 

You can open up the RCM and see how the contacts look.

 

A bad crankshaft sensor will keep it from starting but it will not stop the starter from engaging and turning the engine over.

 

thx fuse 37 is good as are all fuses in the car

 

thx that is very helpful to know

 

Ditto: ZERACER...search tighed1 and/or look for his e-mail address.

 

thx for all the help but still no crank. lights seat windows etc work, battery checked and is good replaced the rcm today and still nothing. so now im stumped if anyone has any ideas id love to hear them. I have no crank no nothing under the hood like it wants to start. thx again

 

If its a manual transmission you could think about the clutch switch

 

I'm having the same problem and am discussing it in a different thread. I still need to have the battery checked but if that checks OK I'll be in the same boat as you. That said, I'd like to see if I am getting the same voltage checks as you.

In the front of the same box as the RCM is connector C106. That connector has a wire in it that comes from the pulse module and energizes the starter - it is in position 6 of C106 (there are a total of 8 positions in this connector but only 6 are used). The "socket" side of that connector goes to the starter (Engine Side) and the "pin" side comes from the pulse module (Engine Compartment Side). You can take a piece of 14GA wire and make a jumper (I used 12GA ROMEX) and jump from "socket" #6 to the positive post on the battery and your starter should engage - that will prove your starter is good.

Then, with a DVM, read the voltage on "pin" #6 when the key is turned to the start position - it should be 12+ volts and should hold that voltage for a few seconds. Mine only has voltage for about a half of a second. Can you check your voltage there and see what you are getting?

 

thx for the info gonna go try this now

 

do you have a picture of c106 and what color is the #6 wire. my voltage checker is not working

 

Look at this thread - Post #11
https://www.crossfireforum.org/forum...n-t-start.html

 

so i jumped #6 to the positive side of the battery and nothing, no starter engagement but it did have a small spark at the battery. so can i assume that the starter is bad?

 

That's a possibility or it could be the wire going to the starter. Do a continuity check on the wire before throwing parts at it. Also, check the ground side of the starter (continuity check) to make sure you've got a good ground. I've seen others on here say that a bad starter on these cars are rare.

We're you able to get a voltage reading and duration from the "pin" in the #6 position when the key is turned to start?
