4agze Ecu And Fuel Question

[original]

just eliminating a few things while trying to get my car started. Does the standard gze ecu prime the fuel pump when the key is in the "on" position? or is that an after market thing?

it will prime it during crank and then keep the pump powered via the circuit opening relay when the car is started.

cheers, ill add that to the list of things todo tomorrow

ok, so no prime on cranking.

 

getting no voltage reading across the fuel pump.

 

what else can I check?

[Kebin[RL]]

it all depends on how your car has been wired. is there a circuit opening relay in the car? if not, a fuel pump relay?

[original]

yes there is a circuit opening relay, diagram says there is a fuel pump relay, but its a conversion so can't be sure

This is how the relays map out and how i believe they connect based on the club4ag wiring diagram, my engine bay and its colours. gotta get a multi meter with buzzer so i can check a couple more things.

 

is this what it should look like?

Who wired up your car? that diagram is crazy... and mostly wrong. What is relay #2 for? What triggers your thermofan relay?

If you wire it as per the factory ae101 4agze wiring diagram then it will run fine.

so, so, so angry right now....

 

turns out some f@$king iron dust got in under the Circuit Opening Relay and was holding the switch open and because its magnetised, it would not move :wub:

 

cheers kebin and medicine_man for your help.

 

 

now to finish my diagrams and understand this mess :D
