cas ca18det dont start engine

[Giannis Leontiadis]

i have signal trig 1 trig 2 and sync with cas ,have 200-300 rpm and engine dont start i have ignition and injector  (work)

i put and 60-2 1 cam vr sensor again i havve signal but engine dont start

what happend

thanks a lot!

Did you actually also CALIBRATE the timing? With a timinglight?

Have you confirmed that you got spark and injector signal?

If your engine can breathe and has good compression, good camtiming, spark at the right time and fuel injected at the right time it will start. Figure what it is missing

[Giannis Leontiadis]

yes i do with timing light i have signal sync engine at 16 degrees then open the injectors and dont start to anyone cylinder suppose to get start...... change cas its same change ignition driver its same

[Steve1436215419]

Enough fuel? Tried to increase coldstart numbers. How is your fuelpressure?

[Giannis Leontiadis]

fuel is good i have 3 bar at fuel line and cant use cold start the car worked and tune with timing light so turn cas from right and burned a safety i replace that but then not work never..... maybe the problem is at ecu? logging is good connect to pclaptop runtimes is work good...

You need to check that the ECU is seeing a RPM signal and no trigger errors.

Check that all inputs are correct and no limits are activating.

You can also use the test ignition and injection functions to check all wiring and operation of the coils and injectors.

The CAS should not need to be moved from the factory position. Any timing changes can be made through the ECU.

 

 

[Giannis Leontiadis]

i have 300RPM and not trigger error.i use the test ignition,injector and its ok

check all inputs are corrects and limits is not activating  there are cases have the e.c.u electronic problem?

[Simon]

Is the spark happening at the correct time?  Confirmed with a timing light?

Do you have igniters in the circuit and not firing the coils direct from the ECU (assuming no smart coils)

 

[Giannis Leontiadis]

Yes i set with light i use siwuencial at fuel direct at ignition i use 4 channel igniter i use spark out of cylinder to look the fire and it has fire when start engine but cant hear (boom) To anyone cylinder always 300 rpm and nothing... If i put the cas at oem position look to light 60 degrees and cant do right from ecu put -30 lock ignition an the best value is 40degrees if i turn the cas i tune with light at 10 degrees to tdc is correct but not engine start . burned igniter? Burned ecu? I dont know

[Giannis Leontiadis]

any ideas to help me?

[Scott]

You could also be firing on the exhaust stroke. Try moving the offset by 360 to get the ignition on the opposing stroke.

[Giannis Leontiadis]

i do this moving from -200 to 300 and nothing before burn the safety the car work at -100 offset 10 degrees ignition lock

[Simon]

When you say it burned a safety is this a fuse or circuit breaker that has been blowen?

If so this is not likely to be caused just by moving the CAS.

To have this happen there will likely be a wiring fault like a short circuit.

If your timing was at -110 and looks correct try a offset of 250.

[Giannis Leontiadis]

yes but when i replace tha safety the engine start after 2 days i will start the car but happend this ....

i put 250 240 230 220 210 ..... and nothing check all wiring all grounds is good

[Simon]

Lets go back to the basics.

Spark needs to be strong and at the right time all the time.

You need compression

You need fuel

We need to find what is missing and then find the reason it is missing.

If the car has run well on a set up in the past there is no reason those settings will not be correct now unless some thing has been changed on the car.

[Giannis Leontiadis]

i can just start the engine but cant calibrate advance setup at 10 ignition advance whith timing light and if i push (done) the settings lost

 

 

the problem before is the spark and wiring at plugs all done now!

[Giannis Leontiadis]

And sometimes when i start the egine disconect form laptop !!

[Simon]

This could be an indication of low voltage at crank.

If you change the offset make sure you hit enter after making the change.

[Giannis Leontiadis]

the voltage is 12.5 v -14v i push enter but then the advance settings lost . i set to 10 degrees push enter and go again 20 when i open the table of ignition calibrate is good when i close(enter-done) is wrong but when i have 10 degrees the engine is bad not up rpm good 

[Simon]

Are you performing a Store once the setting is there?

It would only take a very short drop below 7volts and if a store has not been done it will reset the value.

[Giannis Leontiadis]

i dont understand what did you say please tell me again

[Giannis Leontiadis]

the value at cell change if i put 10 ignition lock and -100 offset an then put 0 ignition lock -100 offfset the value chance but the engine dont work same if open the panel the engine work othewise with previous setting

[Simon]

Is the setting changing if you turn the power off to the ECU?

[Giannis Leontiadis]

no its same if i log again the setting its same and if open the panel the engine work different

[Simon]

When you are in the setting panel it removes any timing that ECU is using from the main tables and any trims.

Once set and you close the setup window  the timing will then change to whatever is in the main ignition table + any trims such as IAT ignition trim.
