Please can anyone help? My mate (Maz) has just put in a B16A1 in the place of his standard ZC in his Jap import '91 CRX. He has bought a Place Racing wiring loom converter, and has found every plug except the 'Knock sensor' wire! He has connected everything except this. The engine turns over but won't start! Does anybody know what the knock sensor does? Would it prevent the engime from starting? What else should he be checking if the engine turns over but doesn't start? Thanks for your help, Matt!!

p.s. Please please help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11

 

The knock sensor has nothing to do with the engine starting. All it does it detect knock, if it does then it just retards the timing. Are you getting any ECU codes? Are you getting spark and fuel?

 

What he said. The absence of the knock sensor will probably put the engine into limp mode, but it should still start.

How easily does it turn over? Does it TRY to start? Is there fuel and spark?

 

No, even if there is no knock sensor it won't go into limp mode, just throw a code.

 

Normally with older cars I found that when doing the conversion, the fuel pumps tend to go. Check to see if your getting fuel.
