Title: EG electrical issue- GRM $2010 Car
Post by: Lowerit on July 01, 2010, 03:24:00 PM
I did a wire tuck on my EG and finally got the car running last night.  The second time I tried to start it the pump didn't prime.

I have checked the pump it's fine , the main relay is fine , car cranks , has spark , but no fuel.

I have been told that if the injector wiring harness isn't grounded out the pump won't prime.


Thoughts??

Injector get constant 12v and the ECU controls the grounding of the inj.

Look at the dead plug on the driver side and see when the key is on that you are getting voltage for yellow/black wires.

Injectors are getting voltage when cranking... going to look @ wiring diagrams.

Look at pins A1, A2, A3, A5 : http://www.ff-squad.com/technet/wiring/obd1/obd1.pin.schematics.gif (http://www.ff-squad.com/technet/wiring/obd1/obd1.pin.schematics.gif)

Make sure you are getting continuity to the inj. clip harness.

The bolt that grounds the fuel pump harness to the chassis , right beside the drivers seat wasn't grounding.


fixed it and the car fired right up , no CEL's ...nothing..
