ignition switch turns but no start
Re: ignition switch turns but no start
It's a pity you have a CPS that is not a genuine Bosch part as a spare. Maybe you might have needed it one day.
Re: ignition switch turns but no start
If the motor does not turn over at all, it is NOT either CPS, cam or crank. They do nothing until the motor is turning.
What we have here is :
1. The RCM, either bad solder joints ( MOST LIKELY ) or a FUBAR relay - search "Mystery No Start"
2. Something going on with the pulse module ( the thing that engages the starter motor, then disengages it when the motor is running.)
These problems have been found to involve the brake switch on manuals, wiring, or the pulse module itself.
The fellow over in Mississippi found it to be a wiring issue.

Re: ignition switch turns but no start
When describing problems it is the important to give all the details.
To those who do not know may not realize how important the little details can be.
Not starting can mean lots of things.
Explain exactly what is happening and then you have a much better chance of diagnosing it the first time.

Re: ignition switch turns but no start
Sorry if I did not provide enough info.
Key turns in switch, all electronics come on.
Motor does not turn over.
Finall found a scanner, and used it, code was for crank sensor.
Installed my back up Bosch and now it starts.
Now looking at having the RCM re soldered, someone here does that???
Have to find out what the FUBAR is.
Thanks for all your help

Re: ignition switch turns but no start
Thanks for all your input.
Replaced the CPS, Bosch for Bosch, no junk.
Started it a few times, went nowhere just checking it out.
Went to store and......... no start, same problem.
Key turns....all electronics come on
Dtinker is doing his magic on a replacement RCM for me.
Any other ideas????????
Thanks

See if they get the same code or a new one.
Re: ignition switch turns but no start
Bob, the CPS will not cause these symptoms, it does not start generating signals UNTIL the flywheel is turning.
This is classic RCM, either the 3 solder points or a flaky engine relay.
Probably not the fuel relay, as it would momentarily start, then die if that was the bugger.
