Causes of ignition failure - 1995 Suzuki GSX-R 750 WS

cam/crank position sensor/s problem
broken wires to the sensors,
problem ignition control module
ECM failure
immobilizer problem
faulty ignition switch ( GMC recall for 12 year problem)
broken timing belt / chain
bad fuel pump operation
these are some of the possible causes

codes p 300 is a random/ multiple misfire===causes spark plugs---HT leads ---injectors/s--ignition coil/s--low compression---wiring
codes p 301,303,305 are misfires detected for no 1,3 5 cylinders === causes listed are engine mechanical fault---wiring---ignition/fuel systems ---injectors---ECT/MAF sensors---ECM
You do not mention if this is a v6 engine in which case no 1,3 5 will be all in the one bank head
With the loud ticking noise that amounts to a mechanical fault associated with that bank
could be loose valve seat inserts , cam lobes failure or cam follower failure or hydraulic lifters problem even loose cam shaft bearings / caps
I would be inclined to remove the rocker cover and check for metal , loose bolts , excessive valve clearance before I went plugs etc
the main indicator for the answer is the loud ticking noise which indicates a valve train problem which will cause the rough running

Short, fuse, cut broken wire, computer failure, or component failure. I would cut the system out since it's an older vehicle.

Ignition failure sensor, follow wiring from coils around back of cylinder headto a black "chip" looking thing bolted to the black steel bracket.

Code p0320 refers to crank shaft position (CKP) sensor/engine speed RPM sensor-circuit malfunction===causes---wiring CKP/RPM sensor ---ECM. Get your hands on an aftermarket workshop manual for the car and you should be able to replace the items

Here is the general definition.

P0320 FORD Description Ignition failure sensor is used to check whether the spark ignition is occurred correctly or not and also used to tachometer drive. The sensor monitors the voltage difference between a resistance which is on the battery circuit for ignition coil. When the ignition coil works properly, the electric current through the resistance is detected as voltage drop. This is confirmed for every ignition event with the crankshaft sensor and the camshaft sensor. If Engine Control Module (ECM) detects a malfunction, no ignition is possible, so the engine would not start. If there is no ignition signal for a predetermined cycle for one or two ignition coils, an ignition coil circuit failure exists.
Possible causes - Faulty Ignition/Distributor engine speed sensor
- Faulty Crankshaft Position sensor
- Ignition/Distributor engine speed sensor harness is open or shorted
- Ignition/Distributor engine speed sensor circuit poor electrical connection
- Low battery charge
- Faulty Engine Control Module (ECM)

Trouble Code: P0320

Ignition Failure Sensor Circuit Malfunction

Possible Causes:


Ignition failure sensor circuit is open or shorted to ground.Ignition failure sensor is damaged or has failed.PCM has failed.

is boiler still under warranty?
normal warranty lasts at least 2 years
if so get ideal to send one of their engineers out
L2 relates to flame failure
either boiler has failed to ignite
or
boiler has not detected flame once lit

several causes

failure to ignite
ignition electrode/spark generator

failure to detect lit flame
detection electrode/detection lead

blocked condensate pipe
or defective condensate syphonic trap

you really need an engineer to check these components

failure inside switch, you will need to replace the ignition switch.

SYMPTOM
P0601-PCM INTERNAL CONTROLLER FAILURE

TEST NOTE
This symptom is diagnosed using the test P0600-PCM FAILURE SPI COMMUNICATIONS.

WHEN MONITORED
Ignition key ON.

SET CONDITION
Internal checksum for software failed, does not match calculated value.

POSSIBLE CAUSES

• PCM internal or SPI
