Your kidding right ? The oil pump is mechanical not electric , no relay .
Full pressure lubrication, through a full-flow oil filter is supplied by a gear-type oil pump. Oil is drawn up through the oil pump screen and passes through the pump to the oil filter.

SOURCE: put new fuel pump, fuse, and relay in 1998 chevy

Did you check the ground wire on the frame. There is a ground wire that is bolted to the top frame rail near the left rear wheel opening. I've seen that wire break or get corroded where it bolts to the frame. I'm not sure of the location on a 1998 but that's where it is on the earlier models as well as the full size trucks. That wire also grounds the gas gauge, does the gas gauge read goofy? Also keep in mind the pump only runs for 3-5 seconds then it shut off, until the engine starts, or the starter is engaged. Good luck!

SOURCE: Where is the oil pump

It is more than likely inside of your oil pan. You will more than likely have to remove it. I would recommend an oil change while you doing this. I have a 2001 s10 crew cab, but I have never had to change the oil yet. Hope this helps!

Slow start ups

Usually it is a fuel pump relay that does not supply a "prime cycle" when the key is first turned on.The fuel pump will get power when oil pressure is present,but you have to crank it a bit before oil pressure builds sending power to the pump only then and while it;s running.
A bad temp sensor can cause slow starting also.

1998 chevy blazer fuel pump wont shut off how do

I don't think you can on that vehicle-probably not a code, anyway. Check the fuel pump relay, it may be stuck on. Should be located in the power distribution box under hood. Pull it out-pump should stop-swap in a different relay to test. If pump still runs on with new relay, the wiring to the relay needs checked.

Dark green provides power to fuel pump relay from the ECU. Orange wire at fuel pump relay is power at all time and is provide from the ECM/Bat Fuse at fuse block (Left side of dash). It also connects to the fuel pump oil pressure switch. The grey wire at relay provides power to the fuel pump and fuel pum oil pressure switch. The red plug thats tape to harness from relay/fuse center is the prime connector..

Having problems with chevy s10 replaced fuel pump

Check the cable that goes from your battery to the fuse box the relay that is clicking is on. Check for lose bolts or corrosion of the contacts or something like that. If the relay is clicking it sounds to me like it is a voltage issue going to the relay.

Where is fuel relay

The fuel pump relay is only for the fuel pump priming when you turn on the key. After the vehicle starts the oil pressure switch takes over and runs the pump. If the pump is shutting off after the motor is running the oil pressure swith is probably bad. Let me know if i can help you further.
