2003 Mazda MPV Q&A

2003 Mazda MPV Question: Where is the fuel injector located?

Looking to replace the fuel injector on our MPV. Would like help locating it. Thank you! -
Answer 1
Which one of the six injectors do you want to find. -
Comment 1
I'm not sure which one is causing the problem. So I'd like to start by replacing the most accessible ones first. -
Comment 2
You would more then likely have to pull them all to change 1 injector, because you have to pull the fuel rail to access them. I really think there could be another problem. Have you had it scanned for codes, if you can get the codes, post them so we can help direct you. -

ProfessorG, Okay, thank you. I'm going to have it scanned tomorrow at a local repair shop, I'll be sure to post the codes once I have them. Thank you for your help! -

Here's the code: P0431 We just purchased this van last week. :( Before purchasing we had it diagnosed and checked by a trusted mechanic. Today it was checked by the same mechanic and he mentioned that the catalytic converter is not functioning properly. It sounds like its the forward one on the #2 cylinder. Right at the exhaust manifold. -
Comment 6
Sounds like you need a converter -
Comment 7
Hi Professor, We had our regular mechanic check it out, looks like it needs a new head gasket. We've owned the vehicle for 13 days. :( Do you recommend Blue Devil or a full head gasket replacement? -
Comment 8
Redo it right the first time. Have the heads checked and surfaced. Should be good to go. -
Comment 9
Okay, will do. Thank you for your help Professor! -
Comment 10
Best of luck and happy motoring. -
Answer 2
You are looking to replace the wrong part. What is the problem, not your diagnosis. -
Comment 1
Hello Parts Guy, The engine hesitates sometimes while accelerating and idling. -
Comment 2
I'm sure you have check engine light on. Do as the Professor has said. Try to get a real scan with a real full enhanced scanner. With a real scanner one will be able to look at the serial data. This info is just as important as the trouble codes. -

Sure thing. Thank you for your help Parts Guy! Here's the code that came up: P0431 -
