Intermitent no hot start 850

posted by  someone claiming to be The Rod on  Fri Aug 8 11:53 CST 2014 [RELATED]

After reading my arse off today I am fairly convinced its either the Camshaft sensor or the Ignition ECU. Looks like the OBD box has an ignition system testing mode built in. If I get good signal(and codes as specified) does this point me towards ECU?

ENTERING SELF-DIAGNOSTICS - IGNITION SYSTEM
NOTE: To perform diagnosis, turn ignition on. Ensure function
selector cable is in diagnostic unit "A", socket No. 6. See
Fig. 1.
Diagnostic Test Mode No. 1 (On-Board Diagnosis)
Press test button one time quickly on diagnostic unit "A" to
display codes. See Fig. 1. ECU can record and store 13 faults at a ti
me in diagnostic test mode No. 1. Diagnostic trouble codes are stored
when a faulty signal is detected.
Diagnostic Test Mode No. 2 (Function Testing)
Press test button 2 times to activate test mode No. 2. LED
should flash rapidly. ECU should deliver an acknowledgment code when a
signal is received from the following:
* 1-4-1 - VSS (as flywheel rotates).
* 3-4-2 - CMP (as camshaft rotates).
* 3-4-3 - Speedometer (as front wheels rotate).
* 3-4-4 - Fuel injection ECU (when throttle switch is operated
by opening throttle).
Diagnostic Test Mode No. 3 (Control Testing)
Press test button 3 times to activate test mode No. 3. ECU
responds by activating components in following order:
* Cooling fan at half speed for 15 seconds.
* Cooling fan at full speed for 15 seconds (15-second pause).
* Variable-flow intake manifold solenoid valve for 2 Hz for 5
seconds (5-second pause).
* Speedometer for 5 seconds by generating a speed signal for
approximately 1500 RPM (5-second pause).
