Two days ago, my car stop running while arriving at a stop.

Since that no way to start again the car.

I've checked the code error and I'm with a code 55.

I'e checked the spark plugs and they were wet o I changed them but that mean i've fuel arriving to them.

I've checked all connections with coilpack, all looks good.

I've tryed a new PTU but still don't want to start.

 

My mechanic said that the ignition is not enought powerfull.

What can I do now?

 

Thank you.

have you tried taking the coilpacks out with the plug still in and turning the ignition over to see if each one fires??

 

also i had a similar problem and it turned out to be a knackered CAS so maybe worth trying another one of them but it all points to the spark so are the plugs gapped properly? or another good tip is clean the plugs up and warm them up first before trying them :)

I did and there is a very small fire.

I spent 3 hours this morning testing the car, plug and other... And the car still don't want to start :nono:

i had same problem for weeks eventually found that i had a broken connection from fuel pump relay to fuel pump, also your proberly flooded car just to make sure take out fuel pump relay & crank it few times then replace it then try starting again, others things to check are cas,relay & fuses, fuel pump ecu, check if pump is priming, also possibe vac leak, sparkplugs & usual connections

How a vaccum leak can cause this problem?

 

Because since somes days, before the car stopped, I was having only -0.3b at idle.

still in trouble and now I'm having a code21 and not fire at all...

Checked the PTU as per Nisan procedure and also open it a per Andy procedure and it looks good.

Also, I've a spare PTU and with each one, no fire at all.

Is your timing belt ok?

Have you got spark in all cylinders ?? if no and your sure you have tryed a good ptu then it could be the cas unit = crank angle senser, to check cas loosen 3 bolts on cas either take it out or leave it in and rotate the end with ignition on should hear injectors clicking & fuel pump if you can hear the above then the cas is ok and problem is else were.

So finally, I did it :D

There were a very bad connection between the PTU and the wire o that's why sometimes code , sometimes fire, sometimes nothing) and also the main and scary problem is that I found a very small (0.3" long) screw on the timing belt cover... This has damaged the timing and made it jump off just for one theeth.

 

I'm relly luky because think to the bad connetcion, it's look like nothing is damaged.

 

Thank to all of you.
