Question about 1997 Chevrolet S-10 Pickup
You might want to put a fuel pressure gauge on it. I'd change the filter too. Check the condition of all rubber vacuum lines. These are notorious for getting brittle.

probably not fuel filter . probably going to have to remove the upper intake and replace the fuel injector spider(fuel inj assebly) if it is droping fuel pressure it is leaking into the upper manifold

have you tried cleaning your fuel injectors? There is a cleaner that you put into the vaccum line that comes from the brake booster to the intake (so it feeds all the injectors all at once) it is called SeaFoam it runs about $8.50 a can. The directions are on the can.

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

This is a very common problem with the 2.2 Liter engine. The Cylinder Head Gasket has most likely failed due to expansion and contraction of dissimilar metals. The Cylinder head is Aluminum and the Cylinder Block is Cast Iron. The Cylinder Head expands at a greater rate than the Cylinder Block creating a Scrubbing Action on the Head Gasket. Another problem on this engine is the passenger side rearmost Cylinder Head Bolt is typically overtightened at the factory distorting the Cylinder Head and causing Gasket Failure directly around that bolt. I have had to resurface cylinder heads and replaced gaskets on many of these engines where these symptoms were described.

I disagree with changing the MAF sensor. I had the same problem for about 4 years until today on my 2000 s10 4.3 4wd 125K. It runs like new, and all i did was paid 6 bucks for a can of mass air flow sensor cleaner from auto zone. Try this!! it was awesome the results
