I’ve had similar issues! I replaced the fuel filter, and it helped a ton. Definitely worth checking that first.
And how do you know if the fuel pump is the problem? Is there a way to test it?

You can listen for the pump when turning the key to the ‘ON’ position. If you don’t hear it, that could indicate a problem. Also, a multimeter can help check its voltage.
That’s a good indicator! Sometimes, just cycling the ignition a few times can help if it’s sticking.

All this talk about fuel systems is making me nostalgic. I remember the days when we just had to pump the gas and pray it started right away!

You could also check the fuel injectors; a clogged or faulty injector can cause issues too.
Yeah, I’ve seen that happen. Just last week, I was troubleshooting a friend’s S10, and it ended up being a bad injector causing stalling issues.
Reflecting on all this advice, it’s clear that proper diagnostics can save you a ton of money. If you have the right tools, diagnosing problems isn’t that hard at all!
Hey! For the 2000 S10 2.2, the fuel pressure should be around 60-66 PSI. If you’re thinking about upgrades, that could change things!
Good to know! If I install performance fuel injectors, will that affect the pressure levels?
Absolutely! Upgrading fuel injectors can actually increase your demand, altering fuel pressure. Just make sure your pump can keep up!

And tuning your engine post-upgrade is key! It helps in ensuring your fuel pressure works well with the new injectors. Don’t skip that part!

Right! What about if I keep my stock injectors but upgrade the fuel pump? Will that help maintain fuel pressure?

Yes, upgrading to a higher flow fuel pump while keeping stock injectors can help maintain a stable pressure, as long as you don’t overdo it!
I suggest checking your fuel pressure regulator too! It’s crucial when upgrading components to keep pressure in check.
What fuel pressure regulator do you recommend for mods? And how do you know if your fuel pressure is off?

I’ve found the AEM regulators work great for performance setups. A good gauge can also help you monitor pressure easily!
Just make sure to check it regularly. Fuel pressure can drop if there’s a clog somewhere downstream.
Does anyone else here have experience with weird pressure readings? Mine’s been fluctuating after some recent changes.
Weird pressure readings can often mean issues with your regulator or bad fuel lines. It might be time to take a closer look!
