Hi there, my 2007 Mazda 6 GS 4-door 2.3L takes a while to start. It starts, but it takes at least 2-3 attempts with 7-8 cranks each. Sometimes after running, it will start instantly 8 times in a row. No problems when the car is running, not that I can tell.
I will probably be replacing the spark plugs anyway, but I think it might be the fuel system because I made the mistake of running it down to empty a few times. I suppose it could also be a bad starter.
Does it start after the "key on position" trick to create some fuel pressure? Sometimes yes, when the key is left "on" for about 30 seconds. Sometimes it still takes at least 7-8 cranks.
I've been quoted about $600 to replace the fuel pump by my mechanic, and I don't really think I want to pay $600 for a $2000 car, since there are additional repairs too (suspension, and eventually transmission). I will be replacing the car in February anyway. But it would be nice if I could replace or clean the fuel pump/filter in the meantime.
I'm looking to see if I can fix it myself. Found a video on youtube and it doesn't look too difficult to remove.
I was wondering if I could get a fuel pump from a scrapyard or similar for $100-200. I'm seeing some very cheap fuel pumps on ebay, which are likely fake.
IS THERE ANY WAY OF CLEANING the fuel pump and filter after removing it from the car? Anything else I should try?
Other things to check on my list:
- Fuel relay
- Spark plugs
- Starter solenoid
- Fuel pump connectors
