Electrical issue after swap

_mr2_ · 06-13-2009, 07:46 PM

hey,
i just swapped in a 5sfe for my blown 5sfe, it is all plugged together and ready to go, but when i put the negative terminal back onto the battery the fuel pump and starter both run, there is no key in the ignition, but it still attempts to start the car. the car doesnt start... my problem is the starter and fuel pump going on there own, i can fix the motor not starting, as it just sint timed yet. i need help asap
thanks alot

checked the relays?
made sure everything was plugged in the right way?
no extra wires anywhere?

all relays work and were tested in my other mr2, they are plugged in, no extra wires. the starter is plugged in correctly, and so is the fuel pump, injectors, etc. we are thinking maybe a ground missing somewhere, or maybe a wire not connected, umm do you know what could cause this problem?

Well the fuel pump comes off the the cicuit opening relay and the starter is activated via the solenoid that engages it (aka an exciter). Is the solenoid for the starter hooked up correctly? Sounds like it may be getting direct power rather than on key.
