[02bluerolla]

well i just finish putting the engine in and wiring up the car. Well i start to crank it but it wont start. i check for spark and theres spark. i check for fuel and turns theres no power to the fuel pump or injector. well i disconected the fuel line that goes on my filter and gasoline started to spray everywhere. i cant think of anything except the fuses, well i checked and none are burned . now iam running out of ideas and dont know what to do . i called doctor tweak and he was helping me go through to daignose my car but i cant use a multimeter lol so i told i called him when i find someone that can. so now am looking for help here at the forums , any help would be apreciated.

You may not have a fuel pump relay depending on how the car was wired up. On the ST and GT models, the Circuit Opening Relay powers the fuel pump. For the 3SGTE's, they added the fuel pump relay and a resistor after the COR (triggered by the ECU's fpr wire) which runs the pump in reduced voltage for normal driving and full voltage when under load.

On my swap, I didn't install the fuel pump relay and am running at full voltage all the time.
You can test the fuel pump by jumping FP and B+ in the diagnostics box.

COR is basically just a latching fuel pump relay.
