SOURCE: 97 s10 blazer cuts out and loses power while driving.

Had the same problem with by 1998 S10 a couple years ago. Changed fuel filter?? didn't work. Changed the fuel pump?? didn't work. Changed the fuel pressure regulator?? didn't work.

I was about to the end of my rope when I put a timing light on it and it showed firing on cylinders more then once a cycle. Turns out my distributor cap was bad and spark was jumping between contacts. When a spark is spread out over more then one cylinder, it doesn't fire correctly and that is causing it to bog out. Simple and a lot cheaper then all the other fixes I tried. Crank sensor was my next option though.

SOURCE: Fuel Guage reading full

this problem is caused by a defective fuel gauge sending unit in the fuel tank.

SOURCE: 2002 Chevy Suburban: Fuel gauge reads empty, tank is half full

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

Good day
You have to look in under the dash and make sure the connections at the back of the cluster is in place. If that is all good then check the fuse box and make sure all fuses are in place and working correctly.
Good luck.

S10 stalls when stopped

Run a full fuel pressure test.
Hook up a fuel pressure gauge and drive it untill hot or when itn does it.
Post back fuel pressure reading and readings when it stalls.
If fuel pressure is up to specs when it stalls then check for lose of park to plugs.


Try to do these once.

1997 blazer my fuel gauge reads past full all the time how can you tell if the gauge is bad

I would guess that your sending unit from the tank is grounding out which means it need to be replaced in most cases. If the gauge is bad, it will usually effect the other readings in the cluster.
