If this is an older vehicle, with carburetion, a ruptured diaphragm in the fuel pump could cause this.

If this is a fuel injected engine, these engines use plastic fuel lines under the upper intake manifold. These lines become brittle with age and sometimes leak causing fuel to run down into the crankcase. If this happens you have to replace the lines, relatively cheap and easy fix.

I am trying to figure this out myself. I have a 96 Chevy S-10 Blazer and I believe it is the vacuum acuator located under the battery box in the engine compartment.

You don't. Fram makes an inferior filter. Use a quality filter such as Purolator, Wix, or AC/Delco, if you want that engine to last.

Assuming it has a 4.3 engine, the oil sending unit is located under the hood, in back of engine, drivers side, next to the distributor. It is difficult to see and get to. Removing the distributor makes it accessible.

The starter is bolted to the engine by two bolts which makes it very easy to change, just remove the bolts and drop the starter down until you can remove the wires from it, it is a good idea to remove the negative battery cable before starting the job to prevent arcing the wires to ground.

Need to know what year it is, it makes a difference.

Could be a plugged fuel filter or a bad fuel pump.

Yes. it is the same as S10. Alston Cassis Works, makes a kit, with everything you need, from mounts, to headers.

Chevy already put the 5.3 Liter V8 in the Impala in 2006. It makes 303 H.P. Putting a 5.7 could be done, but the expense would be great. I would just look for a factory V8.

No you can not , That is what makes and keeps the engine running

The buzzer that lets you know the key is in the ignition in a 1989 Chevy Blazer is in the steering column. To access it you would need to remove the steering wheel with a special tool, or remove the ignition assembly. The key makes contact with a tab that activates the buzzer.

I would answer if you provided the year and engine you are talking about. Chevy makes lots of engines. 4, 5, 6, & 8 cylinders. Want to try again and list this information.

It could be a # of things, You need to have the engine scaned with a engine scanner. Some parts stores will do that for free.
