E46 Won't start! Help please

First off, I come to you guys since I browse this forum any time I want to do any maintenance on my car. Awesome write ups for all kinds of stuff.

Anyway I was attempting to take off my fan shroud to replace my water pump. I had just bought a 4lb hammer, turned the car off and got to work. Put the wrench on the nut for the fan, smacked it with the hammer, and then the wrench bumped into the upper radiator hose and started spraying coolant everywhere. I calm down and start wiping up the coolant then get the hose put back on, then refill the coolant and bleed any air out. Go to start the car and it won't start now. There was also a horrible smell that I attributed to hot coolant when it sprayed everywhere.

I got my gf to try to crank it and it looks like everything is spinning and I even tried to get it jumped and nada.

So does anyone have any ideas as to what might be happening here?

You hit the fan nut with a hammer? Why would you do that? The fan nut is only tightened to a couple of ft.-lbs. It is not so tight that you need beat with a 4-pound sledge hammer.

I used a tip that said I could use a wrench and a hammer to loosen the nut. After several taps with my 2lb hammer and even trying to use a screw driver as a counter lever, I went and tried a 4lb.

You do know that the thread is left-handed.

Left handed thread

Why would you fill coolant back up if you mistakenly knocked the radiator hose off during the removal of the water pump?

And why would you try to change the water pump when the engine is still hot?

As for your problem, who knows what you did....

To Answer The First Question: Yes I Knew It Was Left Threaded And That's The Direction I Used To Attempt To Loosen It. I Want Actually Attempting To Change The Pump While The Engine Was Hot I Was Trying To Test If I Could Finally Get The Nut Loose. I Put The Coolant In After I Put The Hose Back On. And I Don't Know What I Did Either Lol. Sorry For The Strange Capitalization I'm Typing This On My Phone And Don't Have The App Yet

Might want to rule out a fuel related issue?

How much fuel is in the tank?

Can you hear the fuel pump prime?

Re: E46 Won't start! Help please

I have about half a tank and I'm pretty sure I heard the fuel pump come on. I'll double check when I get home. Thanks btw!

2 tests:

1. Hold throttle pedal to the floor while cranking, this puts engine in "Clear Flood" mode, injectors are shut down. If engine is flooded from quick starts and stops, this will likely get the engine started. Do not crank for more than 30 seconds at a shot, wait about 2 minutes between attempts. If engine is flooded, it will start to kick and then likely will started and run rough for a bit.

2. Starting fluid test, this will confirm if you do not have fuel. If starting fluid does not cause engine to immediately start then die, likely the ignition is not firing.

Check all fuses just in case.

Hopefully it is not something major and complicated.

Good luck.

Still checking the fuses and going to try the starter fluid test hopefully today after work.

Ok so I checked the fuses and they are all good. Did the starter fluid test and the engine turned over then died . I also checked the fuel pump relay and it seems to be in working order (i.e. clicking and low resistance). Going to put everything back together tomorrow and listen really hard to see if the fuel pump is actually turning on.

So if I do hear the fuel pump coming on what might be my next course of action?

Read the 2nd & 4th link below in my signature. You can use the hidden menu to verify the amount of fuel in the passenger sided fuel tank. The passenger side should have more fuel than the passenger side fuel tank.

BMAParts.com use SPECE30 discount code for fuel pump and filter.

The other option that may work??? pop the bottom of the rear seat, it will allow you to hear the fuel pump much easier. You can try to bang on the top of the tank to jar the fuel pump to start.

Checked the fuel pump and I couldn't hear anything when I turned the key. I checked if it was actually getting voltage and it had around 5V coming from the connector. It seems to get that voltage even if the car was off so I don't know if that means anything. Also I attempted to apply 12V to the fuel pump to get it to come on and nothing so it might be dead.

Went into the hidden menu and if I'm reading it correctly it looks like there's 33 liters in my tank.

Most like the fuel pump.

5 Volts at the pump is normal unless during the 2 second prime window or cranking the engine.

www.bmaparts.com, use SPECE30 discount code and order a decent VDO/Siemens pump, not the cheaper one.

You will have the pump likely in under 2 days for about $130??

But double check the fuses before you pull the trigger on the fuel pump. If you somehow damaged the wiring to the thermostat and shorted the wiring to the thermostat housing, it could blow the fuse that is also shared by the fuel pump. Do not recall what fuse it is, but just make sure since you were working in the area of the thermostat.

Ok so I did some more digging and could only find the middle fuse in the bank of 5 under the hood that corresponded with fuel (it was good btw). Also the fuse inside the car was good and I checked the relays that correspond with fuel and they both function. Found a link on the bavauto site and followed the instructions and I'm getting 12V when I jumper slots 30 and 87 in the fuel pump relay socket and measure the fuel pump wiring harness. My question is are these two slots highlighted the correct ones I should be getting voltage from.

If the fuses in the DME box are not blown, then I think you should just order the fuel pump, you will need to replace it anyway sometime in the near future,

Since you will be ordering your pump on Fri, likely you will not see it until Tues?

Good luck.

Well...this is what you said earlier in the post.

"To Answer The First Question: Yes I Knew It Was Left Threaded And That's The Direction I Used To Attempt To Loosen It."

Are you SURE you're turning the correct way??
