I'm in the process of learning because I can't afford another expensive mechanic bill at the moment. Anyway, my Mazda MX-6 has a no start condition. It recently had a bunch of work done to it including the timing belt, cap and rotor, and a bunch of things related to the cooling system and whatnot. It ran smoother than ever for two weeks and then one morning it just would not start.
Here's the list of what I've done so far:
-Gas tank is half full
-Battery is charged well
-Engine has spark while cranking
-Fuel pump does NOT come on with the key set to on
-Research tells me the MX6 does not have an inertia switch
-Fuel pump relay has been tested and works fine (and it is clicking when key set to on) so it has power.
-Jumper F/P pin to Ground in Diagnostic box, fuel pump still won't come on
So, on to my questions:
I'm not sure how to access the fuel pump wires to check if they are getting voltage, do I have to drop the tank just for that? Cause it seems like it would be a bit overkill for something a simple as checking voltage.
Now, I don't really suspect that the fuel pump is actually the issue; is it possible that the crankshaft position sensor, or something related there is telling the fuel pump not to come on? (Bear with me as my mechanical knowledge is limited).
If you have any other ideas of what could cause that, please let me know so I can look into that. Thanks.
