Won't start
2000 Expo, 5.4 2wd auto. Wife drove to the store, came out and truck won't start. I'm at work and can't get to it until the morning, so problems were explained to me over the phone and I want to get some ideas where to look first thing tomorrow.
It turns over, battery is good, starter is good so I'm thinking fuel issue. Son checked the inertia switch and it sounds like it doesn't need to be reset. AAA is on the way to tow it home. I'll check to see if the fuel pump turns on. Fuel pressure regulator? Fuel pressure?
JUST ADDED>>She just called and said it started but has a buzzing in the engine area like a buzzing bee. I heard it too over the phone.
Idea's to get me off to an early start?
Thanks,
John
EDIT...She drove it home, tow truck followed just in case, and the buzzing is still present. Anyone have this kind of issue?

I couldn't find anything wrong. I checked the connections at the relay, heard the fuel pump whine, truck starts fine, no codes, buzz is the normal engine sound. Don't know why it would crank and not start the other day.
I'm getting a fuel pressure tester from Amazon this week to check it and to have another tool in my toy box.

I had the same problem a while back, it turned out to be my fuel pump. It would act weird, sometimes it would work and sometimes it would not work at all. I would check the fuel pressure when it acts up again, and see if it holds fuel pressure. If all that is good then the next thing I would go and check would be spark, check if the engine is getting spark.

Connected the fuel pressure tester and the first time I turned the key it went to about 12 lbs. Started it and it went to 32 lbs. Pressed the bleeder, removed pressure and turned key again and it went to 20 lbs, next try was 32 lbs. It was steady at 32 lbs when engine is running, inconsistent readings KOEO. Is this the sign of a failing fuel pump?

Similar symptoms as my '04 put out then the pump failed. But, without a complete and proper diagnosis, you may drop $250+ on a pump and it's not the actual problem. It might be worth a $100 dealer visit.

I thought about that too. But with my readings at the fuel rail, I can only think it's the pump. I think when a relay goes, it's done. New fuel filter was put in within the last 6 months. I'm not into giving the dealership my money. New complete fuel pump is on the way, $134. Wish I could find a Motorcraft pump for that cheap.

The cheapest local fuel pump for my '04 was $263. The Ford pump is around $500.00. Trouble I had was that I broke down away from home, had the truck to a Ford dealer for $60.00. After getting the diagnosis, I could have paid the dealer $100 and then another $60.00 to get it home and then spend a day under it. I bit the bullet and it sucked.

Just a follow up on the fuel pump. I got an Airtex fuel pump through Amazon for $134. When I received the pump, I noticed the sending unit rod was against the box and the bubble wrap was on one side of the box. They should have taped the bubble wrap securely around the part. After pulling my pump, I noticed a slightly different configuration of the sending unit rod (it was bent slightly up and in), but I thought Airtex may have made it that way so I installed it without trying to straighten it to match the original. Well, the rod WAS bent from shipping because I ran out of gas and the gauge was showing slightly less then 1/4 tank. Now I get to drop the tank again and remedy the problem. I'll probably put the old sending unit on the new pump.
What I am trying to say is if you order a fuel pump online (or any delicate parts), TELL them to package the heck out of it so it does not get damaged or bent. This is no big deal, just a few more hours under the Expo. I already told mama not to let it get below 1/4 tank.
