So I recently bought a fully built B18C1 off a 2000 integra gsr. Before we pulled the motor we test drove it and it ran perfect. Now that it’s swapped in my car it won’t start. We have power, all grounds are connected, fuel pressure, oil pressure, and it cranks, but there’s no spark. Any suggestions on what might be the problem. I need help.

 

what ecu are you running?

 

I’m running an obd1 p28

 

Are you using the GSR engine harness? Distributor?
If so are you using the obd2 to obd1 conversion harness?

 

Im using the eg harness, and gsr distributor. The only conversion harness I’m using is a homemade distributor jumper harness.

 

crank sensor

 

Crank the engine for 30 seconds. Then pull the CEL codes. What do you find?

 

what do you mean by crank sensor?

 

No spark and you created your own distributor adapter harness. I would start there.

 

The crank position sensor for the B18c1 is located on the oil pump housing. An EH harness will not have this plug. Simplest but not the cheapest way is to get an obd2 b18c1 harness.

 

 

Nope... the crank position sensor on ANY year B18C1 is found inside the distributor. The Crank Fluctuation Sensor (CKF) is an additional sensor found on '96+ USDM B18C1's and it is located on the oil pump housing.
