1st Gen R53 Cooper S Most liked posts in thread: MY MINI COOPER S 2006 112K MILES WONT START HELP PLEASE !!!

Just an FYI about the MINI fuel pump. An adequate fuel level within the pump housing is maintained regardless of the tank's fuel level; except when the tank is run dry. The caution for maintaining levels greater than a quarter tank is to minimize the possibility of ingesting excessive contaminant at the bottom of the tank; the OP's dad was correct. For example, water is heavier than fuel, so if enough accumulates it will pool at the bottom of the tank, and get sucked up at a greater percentage than fuel if that's what remains available.

I resemble that character, but I'll give you my three cents anyway.
1. Seek professional help.
2. Replace the crank position sensor.
3. Test fuel pressure with a gauge, no short cut here; if it is OK, look elsewhere than fuel delivery (although injector filters could be clogged), and disregard the rest of my recommendations. Remove the fuel filter unit and reconnect the two halves, taking care they're completely pressed together and locked. Look at the feed hose to the fuel pump to be sure it is not cracked. Perform diagnostics to rule out an obstruction or disconnect in the tube from the filter sending unit to the pump. One positive telling point is when you install a new pump it works for a short while, this probably means the circuitry is OK.

 

Making a post like that will turn people off from helping. Being from New Jersey i don't consider myself a "redneck" but I sure am sarcastic and I have good information but according to you I can't post

As what everyone else said, many times you will save a lot of money if you have a professional just look at your car.

 

Wow, that's some response.

First time in almost 4 years we've manages to upset someone like that.

Oh well...so much for trying to help.

I'm closing this thread as there is no need for any more discussion here.

 

I wonder if Siri has an answer. Maybe she could even make the appointment for you.

 

You may have missed my advice. Once again...

I agree with Nathan. No sense throwing money & parts at the car. So far it hasn't worked & it has cost you a lot. Cut your losses & take your MINI to the dealer for a repair or at least a diagnosis. I know that is not what you want to hear, but I think at this point it is sound advice.

Good luck & let us know what it was.

I have not had your issue on my 2006 MCS.

 

^ Don't feel bad you tried as has everyone who have posted in this thread. Your latest advice is very sound.

 

^^^^ + 1000 X's

I am not a "redneck" but I have redneck friends so lets not try an insult people you dont know. I am sarcastic but it's just part of me being me and I live in the NE. (Philly)

The best tool you can use to get your car started is the phone. Call the dealer and make an appt.

 

I'll own up to being a Country Redneck, which doesn't always have a negative connotation.

 

Does it crank?

 

:cornut: The gear heads start coming back on line around 0800hrs in the morning. Try back then.

Have you filled with fuel from Costco?

When the key is turned to the second position, do you here a couple clunks from the left rear seat area?

Turn the key to the second position for a few seconds and turn off, remove the intercooler and disconnect the fuel line; cover the quick connect fitting with a rag while disconnecting. If there is a lack of pressurized spray, the fuel pump is not working. A better test, attach a fuel pressure gauge to the Schrader valve on the end of the rail to see if pressure builds when the key is turned to the second position.

 

You may not be able to hear it;

First pull a plug, re-attach it to the wire, turn the car over, check for spark. May actually not be the fuel system at all, at least this will rule out or bring into suspect the ingnition system.

If you have spark, the simplest way to check the fuel pump is to, pull the I/C, bleed the fuel system from the bleeder at the end of the fuel rail, (use a rag or something to catch and soak up the fuel from the bleeder), then go back into the car (don't put anything back together) turn the key to the run position without trying to start it, leave it on for a min. or so, turn the key off, go back to the bleeder & see if you've built up pressure again, if so fuel pump is fine, if not start on troubleshooting it.
