P1250 is a diagnostic trouble code (DTC) that indicates a problem with the fuel pump control circuit in a Geo Metro. Various issues, including a faulty fuel pump relay, a malfunctioning fuel pump, or a problem with the wiring or connectors in the fuel pump control circuit, can cause this code.

What is the cost to fix the P1250 error code?

The cost to fix this issue will depend on the specific cause of the problem and whether you choose to have a mechanic or repair shop fix it or attempt to fix it yourself. The parts needed will also depend on the cause of the problem but could include a new fuel pump, fuel pump relay, or wiring and connectors.

But if we take it at its worst-case scenario, and there needs to be a new fuel pump put in, it looks like the price will be around $150-$225. This is for a new part for your geo car , so you might be able to go to the auto wreckers and get a used one.

If you decide to fix the issue, you will likely need basic hand tools such as pliers, a socket set, and a multimeter to test the wiring and connections. Additionally, you may need to consult a service manual for your specific make and model of Geo Metro to troubleshoot the problem and determine the necessary parts and repair procedures.

Like everything with cars, if you DIY, it will be cheaper as you have no labor costs… but it takes up your time. So it is up to you to figure out which is the best route for you to go.

How long does it take to fix a fuel pump issue in a Geo?

If you have experience working on cars and have the necessary tools and equipment, you might be able to diagnose and fix the problem relatively quickly. In this situation, if the issue is a faulty fuel pump relay, you may be able to diagnose the problem and replace the relay in a matter of hours.

But, if the problem is more complex, such as a malfunctioning fuel pump or a problem with the wiring or connectors in the fuel pump control circuit, it may take longer to diagnose and repair the issue. So it is hard to give a hard time frame, but for a fuel pump swap with someone who knows their way around cars you might be looking at between 3-5 hours total time.

Once you are done you might need to disconnect your battery before restarting the car to clear the code. Here is a great video that shows how to do it :

Overall, the P1250 error code in Geo cars is a common problem that can take a couple of hours to fix if you want to do it on your own. The cost of the repairs depends on the parts needed and labor costs, but it should not exceed $225 if you do it yourself. It is important for owners of Geo cars to be aware of this error code and how to identify it.

Fuel pump replacements are probably not the best first project for someone, as they require a bit of movement of bigger engine parts. But it is a straightforward swap, so it isn’t too difficult.
