im tryin to figure out why my injectors arent firing.....inhave a 91 b18a and it ran in the car i have it in.....all of a sudden it would just spin and spin and spin....i would like to know if anyone knows EXACTLY what would cause the injectors not to fire.....i swapped out the distributor....not knowing if either works now though....it will however start on ether....but then just stalls out....if you can help please do.....thank you

 

Check the driver circuit(resistor block) and ground wires on the injector harness.

 

yeah and check for voltages and grounds at the injector wires. also check all cylinders for a spark.

 

Check the main relay and the injector resistors.

 

you know where to locate the resistor block???????? cause i cant find it.....and im gettin mixed reviews on it even existing

 

You can get a Noid Light at Pep Boys for about $3-4 to test for voltage pulse, might help.

 

did u put the ground for the injectors?it should be on thermostst housing.
