Last night my Saph had a BIG misfire (iluminated all the street lol) and then got dead.

Engine runs well, and with compression, but won't start.

Any ideas? thanks

 

Try the ignition first do you have a spark at coil lead?

or could be fuel problem?or electrical,

Good luck

 

Checked some minutes ago and seams that fuel pump is dead. At least I don't ear it as in the past. but if it's the problem, it's common the big misfire?

 

yes that can happen
Try connecting pump direct to battery and touch terminals to try to jump it back into life?

 

I have fuel at the injectors but don't know if pressure is fine. I have spark on coil lead. Will switch fuel filter tomorrow and see whats happens.

 

Hi,
you could try checking your crank sensor plug, disconnect it and give it a clean and try reconnecting and see if that cures it.

Mike.

 

Crank sensor plug is the sensor itself (at the crank pulley) or anything else attached to the block/head?

 

re-read your post and got it, will clean it also and see. the heat here is getting my brain out of place thanks

 

Had a lot of tests today and still don't start.

I have sparks ONLY in 1st cilinder, all other 3 don't spark at all. Any ideia? is this a phase sensor dead or so?

Fuel pump is running well, fuel filter and spark plugs are new.

 

If you have spark in only 1 cylinder, seems worth looking at your dizzy/phase sensor, all cheap stuff too

 

already done. still the same
