It does act like it is flooded a little and I can smell the gas so that is probably a result and not the problem. It seems like it is ignition electrical related. No codes. No check engine light. Runs great after it starts, but I fear a more severe failure may be coming. If it has been running and is warm. It will restart immediately just like it used to do all the time, but not every time.

Has anyone had this happen? Cleaned and then changed the IAC sensor. Ran Techron fuel injector cleaner through twice. Still the same thing. It seems like the engine is not getting spark immediately. Could that be possible? Ignition coil? or?

Any suggestions would be greatly appreciated!
i have had this problem you are talking about and the solution did not cost anything. i had this problem with the last 3 ford vehicles i have had. it is related to the fuel pump and fuel draining back to the fuel tank(pump or filter may have to be replaced). to resolve when you start your vehicle leave your ignition key in the on position for 30 seconds before you try to start it. this will give your old pump time to reprime the system.also i assume you are not letting the ignition key touch the other keys when you are trying to start it. this will cause problems too.

New to forum, and having the same issue on my 2000 4.0L. At first, since the MAF was only a few months old and the hard starting just started, decided to replace fuel pump. Just bought the pump assembly itself not he sending unit, pulled the bed and replaced pump same thing. Since MAF was under warranty, changed that..same problem. My mechanic friend did some calling, was told about a fuel damper on the fuel rail that may not hold the fuel pressure with the new pump. With 115K miles, it seems a like a domino effect. What is the part on the transmission that failed. Also having problems withthat shifting...save that for another day and forum. Thanks...this is a great forum.

its been a a week now, and it has started first time everytime, so no more cycling the key everytime to start it. also to the post above, u still could be having a pump related problem, because i think, and i'm not sure but in that pump assembly is a regulater / check valve , so if u only replaced the pump u wouldn't of got that,

someone else enlighten us,

Problem solved on 4.0l starting problem. The additional problem was the fuel regulator which is part of the fuel pump assembly and can not be replaced separately. So, it may have been the pump or the check valve on the pump as well going bad. It is a weird problem because the symptoms can be caused by different parts gone bad. Well at least this one is fixed and should last awhile. I hope this helps.

Well I gotta say it does look like I am going to replace the fuel pump as a final fix to this issue. What a pain. So many people seem to have run into this, but it seems to manifest itself in different ways and makes diagnosis difficult.

Taking it into the dealer results in a large bill and is only fixed if the mechanics at your dealer know about this problem. No check engine lights and no good easy way to figure it out.

It's too bad Ford didn't put a decent fuel pressure test port on the SOHC 4.0. That would help.

I will post after I replace the pump and let everyone know if that solved the issue completely for me.

Hey iowafx4,

Just a couple of questions if you have the time.

How did you remove the locking ring on the pump? I see there is a special tool kit available and perhaps my local auto emporium loans the tool out for free. Just curious.

Also, did you take the bed completely off? I was thinking about puting the rear on jack stands, removing the tires and perhaps then being able to move the bed back enough to gain access to the pump. Advice?

Or can you take out the bolts etc. and maybe tilt the bed to gain access?

I know a number of the posters here have done this already, but I don't recall seeing anyone post as to how they manuvered the bed.

Any help would be appreciated.

BTW, the pump is on the way. Got it from Amazon of all places. Same model and everything, but no tax and free shipping.

Hey lvbluesboy,
Remove the 6 bolts from the bed, a 55 torx bit. I used some penetrating oil to help. y friend has a lift in his garage, so we were able to lift the bed right of the frame using tie down straps, the bed is not to heavy.
You probably got to slide the bed back( so not to hit the cab when tilting) then tilt up about 2 feet to get enough access and clearance to pull the pump out. A screw driver and soft mallet was used carefully to loosen the lock ring until I was able to loosen by hand. Same thing when tightening. There is some spring tension on the pump when reassembling, so 2 sets of hands can really help. The clips on the fuel and vent line on the pump were removed with a small screw driver. Some good lightening to see those clips is helpful. Not to bad a job, just think ahead and be careful with the bed above your head.

Thanks for the info jscrenci63!

Probably going to happen next weekend as the pump won't be here until next Tuesday or so.

Going to be very careful and take it slow. Just want to be careful since fuel is involved.

I will post with any observations and concerns after this little task is done.

OK. So replacing the pump did the trick. No problem starting now at all. I did have a local shop that I know do the actual replacement. My wife went balistic about me fooling around with the fuel tank so rather than risk her rath, I contact the shop I know and had them do it.

Everything is fine now and the truck runs great. For those of you still dealing with this, I do have a suggesting if you would like to try the replacement yourself. Since I didn't have a lift, I was going to take off the bed as a way of access. My idea was to use an engine hoist and four tie downs to attach to the bed. Role the hoist over it from the back. Attach the straps to the four corner anchors and lift straight up. It would work fine and elimate having to lift the bed up yourself (with some friends).

So, if you find that you can start your truck by the turn to on a number of times (for about 2 or 3 seconds each) and it will then start, you are looking at a failed fuel pressure regulator valve, which is part of the pump assembly.

Learn from my several months of troubleshooting and parts replacement. New MAF, IAC and fuel filter at least.
