Re: When do Injectors inject?

[DMCVegas@xxxx]

Since the system is mechanical, the answer would be yes. If you were 
to jump the fuel pump relay to start the fuel pump, the injectors 
would open.

A fuel pressure gague can help you determine the failure of certain 
fuel system components by way of measuring what the fuel pressure is 
durring specific conditions. To the best of my knowlege from what I've 
read from the service manual and the BOSCH manual, a fuel pressure 
test gauge is not able to determine fuel delevery issues with the fuel 
injectors. For this test you need to have each injector spray fuel 
into an individual container. The container is usually clear so that 
you can 1. Make sure that they all fill up at the same time (even 
distribution), and 2. To verify that they have a correct spray 
pattern. Using the feed back from both of these visual tests, you'll 
be able to utilize the info from the manual to determine the proper 
repair nessisary.
