(87rx7 N/A ) ok so i installed a new motor i hade the wiring harness out and labeled so i put everything in when i went to start the car it just turns over it wont start the fuel pump is not getting power nor is my dash lights, headlights, brakelights iv checked fuses all good when i try to turn the lights on the puzzer goes off same when i hit the brakes this is from the harness on the drivers side

 

is there a ground i forgot somewere cause iv looked and cant find anything

 

first check if its missing fuel or spark or both. Dash lights? got me. but Id start there

 

maybe you forgot to put the harness ground in. if its n/a its behind the oil filter kinda by the bellhousing

 

or what you can do is hold a test light to the ecu side of the harness along with the fsm to find out which sensors are getting power. you crank the motor and check for power at the ecu with the test light

 

i checked it out and its not getting fuel or spark

 

i got it it was just a ground from the motor to the chassis thanks for the info

 

my rx7 is now running
