GOOD IVNING .I HAVE A CUESTION . MY B18 B NO HAS FIRE IN THE FIRST PISTON THE OTHER 3 HAS FIRE .WHAT PROBLEM I HAVE .I CHANGE THE DISTRIBUTOR FOR NEW ONE AND WE CHANGE THE SPARK WIRE . NOTHING CHANGE . SOME BODY TOLL ME THE CRANK SENDOR BUT THE INTERNET SED HAVE AND NOT HAVE SENSOR . CAN SOME BODY HELPME PLEASE .?

 

compression test, check if that cylinder is getting spark then check if that cylinder is getting fuel. it's easy to see if it's getting fuel just take the plug out and see if it's wet/smells of gas.

 

I have gas but no fire .the ihnition not send fire to the spark plug
The other 3 has fire. This motor come wiyh crank sensor or not ?

 

the crank sensor should be mounted right by the crank pulley on the oil pump unless this is a jdm engine. either way that won't prevent that cylinder getting spark, while most ppl won't recommend it have you tried taking the plug out and resting it on the valve cover and have someone try to run the car. That way you can at least see if it's getting a slight spark even if it's dull orage, it should be bright purple. You can damage the coil by doing that so do it once maybe twice with the light off just to see.

 

I CHEK BACK TO THE CRANK PULLEY . I FOUND NO HAS SENSOR . DO YOU KNOW IF IS POSIBLE THE IVNIYIOS IS YHE PROBLEM .BECAUSE OTHER PEOPLE SED THE SENSOR IS INSIDE THE IGNITION . MY PROBLEM IS NO FIRE ON 1 PISTON .DID I CHANGE YHE DISTRIBUTOR AND THE WIRE BUT NOTHING CHANGE .
