Using Starting Fluid
The starting fluid test is an ancient test dating back to when all vehicles had carburetors.
If the engine is not starting, the starting fluid test will confirm (or disprove) that the no-start problem is due to a lack of fuel.
It's important to note that it does not directly test the fuel pump, and as such, it may not be 100% reliable (in diagnosing a bad fuel pump).
Don't let this discourage you from performing the starting fluid test since it can quickly point your no-start diagnostic in the right direction.
IMPORTANT: To get the most accurate test result, you need first to make sure that the ignition coils are creating and delivering spark to the spark plugs. Test all four cylinders for spark with a dedicated spark tester if you haven't already.
OK, let's get testing:
- 1
Remove the intake air duct from the throttle body.
You don't have to completely remove it, since you'll have to reconnect it in one of the next steps. - 2
Open the throttle manually, and spray starting fluid down the bore.
When you have sprayed a good squirt of starting fluid, quickly reconnect the air duct to the throttle body (you don't have to tighten the hose clamp).
Reconnecting the intake air duct is a very important safety precaution in case you get a back-fire thru' the intake manifold. - 3
Crank the engine once the intake air duct is back on the throttle body.
- 4
You'll get one of two results with this test:
1.) The engine will start momentarily and after a few seconds will die.
2.) The engine will only crank but not start at all.
OK, let's find out what your results mean:
CASE 1: The engine started and ran for a few seconds. This test result tells you that the engine notes our problem is due to a lack of fuel.
Usually this means that the fuel pump is bad but you still have to make sure with a fuel pressure test gauge.

CASE 2: The engine did not start, not even momentarily. This test result generally tells you that you are Vehicles no-start problem is not due to a lack of fuel. Still, I recommend doing a fuel pressure test to make sure
