 Motor shut down. Running wot for ten minutes. Motor dies. Try to crank. Motor turns over great does not crank. Turned just key, do not here the little whinning sound that that I usually here when the fuel pump primes. Motor is 37 efi. 40 hrs. Checked power to fuel pump with volt meter it has power. What's the deal, why would it just quit. No issues with this before.
Could it be fuel pump??
Or is it fuel pump not getting signal from motor to pump??

Re: Motor shut down. The EFI has 2 fuel pumps.
Which one did you check?

Motor shut down. Even if the fuel pump(s) have power to them doesn't mean they are working as well make sure your getting fuel from the tank first could have had a line full and then won't take suction from the tank seen many times were the fitting on the tank isn't completely pushed on or the seal fails from putting on wrong

Re: Motor shut down. Ok I'll take a look. What about that priming noise I hear when I turn the key to the cranking position?

Re: Motor shut down. So for starters what exactly is the sound u hear when turning the key to the on position. Sounds like it comes from the motor?

Re: Motor shut down. Yes there is one under the air filter and one mounted on side the engine.
If the pump mounted on side the engine (silver) goes out the engine will run as long as you keep pumping the bulb.
If the main pump goes out the engine will not run at all.

Re: Motor shut down. Ok thanks. Is the main pump something I can replace easily or do I need to take to dealer??

Re: Motor shut down. It is more than likely one of 2 issues. A Broken wire at the Fuel pump module or a broken ground near the relay box.

Re: Motor shut down. I would bring it to your closest service center. Where are you located?
