As you evaluate my advise and suggestions, there are a few things you must keep in mind:
• I did not diagnose your problem and am therefore only able to evaluate what you tell me. For example, if you ask me a fuse location, that doesn't mean that I can tell you the reason why the fuse blew.
• A thorough diagnostic approach involves the use of technical equipment, xuch as voltage meters. scanning equipment and other sophisticated devices.
• Lastly, fixing one problem can very easily reveal a problem with something that you might consider unrelated. If that happens, you might want to view me as being incompetent.
Subject: The steps one must take to measure the fuel pressure on a fuel injection engine
Customer's description: where is the fuel system test port located on a 1995 grand am? the car engine has been stalling out, when first started not much power until the engine gets warm
Discussion: Provide the customer with the response requested. However the problem may well be the idle relief valve, the crankshaft sensor, the camshaft sensor, or the fuel pressure sensor.
There is a large is attached to the fuel sender assembly to the top of the intake manifold and supplies fuel to the injectors. A fuel pressure tap is located on the rail for quick pressure checks.
If you don't have a pressure gauge, AutoZone will loan you one FREE.
HINT: Try and find an Actron CP9110 code scanner so that you can perform a full diagnosis of your problem.
