In addition, to do an even better test.

just unscrew the fuel Rail, pop the rail up.....

Place a piece of white xerox paper under the injectors, Crank the car..

you will see fuel squirt out,

and which ever injector doesn't squirt, bamm. you solve the problem.

You can see the fuel dots that is squirted on the paper.

If one to 3 are not squirting, you have bad injectors, if all 4 not squirting, then most likely bad pump.

And that is the Tech of the day~ How to check the Fuel system and diagnose the source....Bet no one thought about that huh!

KA injectors go out commonly. I replaced a lot of them in my cars.
