Simple Fuel Pump resistor Q

[tougespirit_jzx81]

okay i know this is a retarded :aigo: question BUT.....just gimme a y or n awnser.

If the fuel pump resistor on a 92 Supra Turbo (7mgte) (little silver box that bolts on to the FPR bracket on the exhaust side fenderwall) wasnt plugged in, the car would, start but wouldnt run for more than a few sec, am i correct?

if the resistor isnt plugged in, i cant see the car starting at all unless you jumper it with a wire. so your answer is probably.

hmmmm, well iono, im gonna mess with it again here when i get off work, i'll post up if i figure out whats wrong, thanx for the reply

What shaeff said.

The resistor pack is there to limit the current to the injectors. It's needed because the injector coils are low "impedance" (an incorrect term btw). Without the resistor pack the coils in the injectors would fry in short order.

Since the injectors are supplied with 12 volts through the resistor pack disconnecting it would result in no injector operation. No injectors = no fuel. The car may fire from the cold start injector if the coolant temp is low enough but it wouldn't run. It wouldn't even start if hot.

fuel PUMP resistor NOT fuel injector ballast

Heh. He's got you there Jetty
IMHO just cut the yellow wire and be done with it. Unless you want to perform harness surgery, then by all means, remove the assy properly.

aaaand here's how you can remove the resistor AND relay.

ive removed both the resistor and the relay with NO ill affects. might just be my ride, but hey, its insight.

Lol, he sure does. A serious brain fart. With all the injector posts I've been doing lately I really screwed the pooch on this one. Gotta slow down and actually read the stuff. Thanks go out to figgie for being gentle
