Headlights halogen high and low beams combined - 17 to 19 amps. 70psi pressure at the regulator could easily be 80psi plus pressure at the pump causing your normal.

Fuel Pump Diagnostics Using Voltage Drops And Current Draw

Unplug this relay to isolate.

. Ignition System primary circuit - 6 to 20 amps. Fuel Injectors - 4 to 6 amps peak 1 amp hold. One goes to the fuel pump relay under the seat.

14 to 15 psi 3 to 4 amps 30 to 45 psi 4 to 7 amps 45 to 50 psi 7 to 8 amps 50 to 70 psi 8 to 12 amps. You can do what Krytox saidor just get a multimeter measure the resistance of the pump then use V IR rule and you can work out the amps drawn using either 144V or 12V. Filter hoses fittings bends etc Ie.

Small bulbs LED usually in a new car for dashboard - 004 to 006 amps per bulb. An amperage level above or below the specification indicates a malfunction is present if pressure is low and amperage is above specification. Well if your fairly certain that 15 amps is sufficient chuck in a 10 amp fuse and hopefully it stays unblown.

A good pump will produce a pattern similar to the one shown here. Each vertical division is equal to 1 amp so the pump is drawing between 5 and 6 amps. The amount of amps your fuel pump will pull will depend on how much fuel pressure your fuel pump should supply to your fuel rail.

Unplug this to isolate. A good pump will produce a pattern similar to the one shown here. The wirings able to hold 15 amps constantly so I think that should be sufficent consider CAPA reckon itll only draw half of that.

If pull those 2 relays and 2 fuses the 10A draw should. I would think about 10A. The amount of amps your fuel pump will pull will depend on how much fuel pressure your fuel pump should supply to your fuel rail.

The scope is set to 100mV per division and the probe is on the 100mVA scale. If the pump is good the waveform humps. Headlights High Energy Discharge - 12 to 14 amps during initial start 7 to 8.

Ideally the fuel pump should be powered ON using the same wiring thats used during normal operation. Electric Cooling Fan depends on the size and how it turns on - 6 to 30 amps. Electric Fuel Pump depends on pressure and flow - 4 to 12 amps.

I know there is no specific number as there are many factors that. As a rule of thumb on port fuel-equipped vehicles fuel pump current draw increases by 1 amp for every 10 pounds of fuel pressure. Nothing to lose except a 50c fuse.

Each vertical division is equal to 1 amp so the pump is drawing between 5 and 6 amps. Less than the fuse that protects it. One is fuse 4 15A and the other is fuse 1 15A.

ANother goes to the rear defrost relay under the drivers side of the dash nea your left leg. Headlights halogen high beam - 9 to 10 amps per pair. Headlights halogen low beam - 8 to 9 amps per pair.

Electric Fuel Pump depends on pressure and flow - 4 to 12 amps. Keep in mind that when picking a fuel pump based on what pressures will be run err on the side of caution as most systems do have a larger pressure at the pump than at the regulator due to restrictions of flow in the system IE. The other two wires do go to fuses.

Does anyone know off the top of their head approximately how many amps a new fuel pump draws on a 99 silverado 48L. A good rule of rule of thumb for this test is as follows. I know there is no specific number as there are many factors that affect amp draw of a fuel pump.

Now with 39 shrooms. Electric Cooling Fan depends on size - 6 to 30 amps. Posted February 27 2015.
