Chevrolet venture 2002 fuel pump fuse in underhood fuse box blows on just switch on the ignition switch even the pump connector is removed

There is no reset switch, you likely have a bad fuel pump, try this use a 2x4 or soft hammer to rap on the fuel tank as someone turns the switch on and off when you hear the pump hum the car will start and run but change the pump immediately. Almost every other problem that occurs in the fuel system will cause the check engine light to come on and it will set a readable code. I hope this helps. Take care.

The diagram of the fuse and relay layout is on the bottom of the fuse box lid.

Did you try all the suggections ?

fuel pump is bad,your relay will be also from trying to start pump.there is an outside chance your relay is bad,easier to change that first

e fuel pump motor may have failed, causing a short and blowing the fuse. Try unplugging the fuel pump connector at the pump, then turn key on with a new fuse in place. If the fuse blows again, it could be a short in the pump's wiring. If the fuse doesn't blow, it is likely a bad pump.

If you have a four cylinder, the fuel pump doesn't have a separate relay, but rather its relay is built into the ECM relay. This relay is behind the center portion of the dash bolted onto the right side support bracket there. It's powered by one of the 30A slow blow ignition fuses in the underhood fuse block.

If you have the V6, there will be two separate relays on the above referenced bracket. The fuel pump relay should be the lower one of the two. For this relay, power originates at the 20A fuel pump fuse in the underhood fuse block.

Hyundai's online schematics are an excellent tool for this task. Simply register for an account at www.hmaservice.com. When inside, go to the ETM (Electrical Troubleshooting Manual) link in service information, select your year and model and MFI fuel system. The first page will show you the relay and additional information. If you click on the connector number for a component, it will bring up a separate window, in which you can click on links at the top to show a diagram of the connector, a picture of the component/connector, and a diagram of the wire harness in the vicinity of the connector.

the fuel pump relay is located in the underhood fuse box. but it is not required to replace if it is defective then was probably the problem all along

The fuel pump relay is located in the fuse junction block,under the hood
on the left fender. There is also a fuel pump+injectors fuse, in the fuse
block behind the left side of the dash. It should be marked f/p-inj.
Hope this helps.

that red wire is a test lead to jumper the fuel pump to test it.if ecmb fuse keeps blowing my guess is your ecm has a short in it,in that case it can be purchased at oreillys

It appears that it is part of the fuel pump circuit, so I would concentrate on wiring harness & connector at fuel pump, clean it real good, and apply dielectric grease to the connection, as well as the fuel pump relay, connector & harness.
