Ford - Explorer :: 2000 XLT - No Start / Low Fuel Pressure
Oct 20, 2010
2000 explorer XLT, 4.0L, OHV (VIN "X")---sitting for 15 months, engine turns over but no start unless 10 cc's of gasoline into intake manifold, then runs for 4-5 seconds. Fuel pressure of 5-6 PSI at fuel rail AFTER replaced fuel pump assembly and fuel filter. I can hear fuel pump come on for about a second with key on. Doubel checked fuses and relays for fuel pump and PCM, then again checked that engine would run briefly with gas squirted into intake manifold. Questions:
1) Could fuel lines be clogged after sitting for over a year?
2) Area driver's side next to spare tire, underneath jack storage, where return fuel lines are clustered (nuts are rusted and need to be sawed off)---some type of fuel regulator here? I thought fuel pressure regulator was on fuel pump assembly.

I have a 2000 4.0 Explorer that sometimes will not start. It has happened on cool mornings as well as hot days after I shut it off, for example, shutting it off to fuel up. I always turn the key to the on position and wait a second or two before cranking, and when I do that, I can usually hear the fuel pump. It's when I don't hear the fuel pump that I know it won't start, and sure enough, crank and no start. My question is, is the fuel pump going out? Or another thought I had was maybe the inertia switch starting to fail? It runs great when it starts, just has a problem starting sometimes.

1995 Ford Explorer, 4 ltr. engine, pushrod. Will not start. Replaced fuel pump, fuel filter, every relay, pressure regulator, and the crank position sensor. I realize there's a whole bunch more parts under the hood, but I am ready to give up. Before the fuel pump would not run. Reason for replacing the parts. Now it won't stop running and you can feel the fuel by-passing at the pressure regulator. When checking the pressure at the rail I get zero !! I used a tire pressure tester for this. And, like I said no pressure. This vehicle has around 170,000 miles on it.

Problem: More often than not when the key is turned to run (?), prior to engaging the starter, the fuel pump does not turn on for its 5 seconds. I have installed a fuel pressure tester gauge to watch the fuel line pressure. It was a little shaky to diagnose because if the line had pressure/fuel from the previous run it will start and run a short time and then die from lack of fuel. Unless the fuel pump activates when the key is turned to run, prior to full start, then there will be no fuel coming from the pump. No start. If you work the key to run a few times until the pump engages its good to go. The truck has never died while driving, once it gets that initial pump activation it runs good until the next start up cycle. When the pump does work it builds up to good "book" pressure and holds it at 39 when the engine is shut off.
We have put off changing the fuel pump for obvious reasons but can not see how it could be the problem since it has never quit once after we get it started. Are we wrong? We know the fuel shut off is on as it will run. We have changed the key lock tumblers, the ignition switch and the fuel pump relay. (behind the radio). Next up is to re-seat all the fuses and relays in the main fuse panel box under the hood. I just read that today on FTE. Is there a test we can do or some engine codes we need to look for? This problem is getting old fast.

I have a 03 explorer sport trac that has no fuel pressure the pump will not run. It is a bew pump just replaced it amd drove 4 miles cut it off filled up with gas now it wont run I replaced the pump again thinking I might have got a bad pump but it still wont run. I've checked the relay and inertia switch I have the 5 pin connector on the fuel pump module. 1 wire has good power to it but the pump won't run...

I have an 03 Explorer that had a starting issue. Long story short, it had no fuel pressure. So after testing the relay, I switched out the pump with an Airtex unit . All seemed fine...for a while.
Became hard to start again, checked Schrader valve with the key on, and not running, no pressure. Strange though, it would run.
So got the fuel pressure gauge on it. Turn the key and pressure will go to about 5-10psi and then drop to zero. Turn key off and on again, up to 5-10psi, then drop to zero. Turn the key to start and pressure goes up to 10psi, then starts, then goes to 30 while running and you can drive it around. Shut off motor and pressure goes down to zero.how the sending unit is supposed to hold fuel pressure and not release it? Is there some kind of check valve in the sending unit assembly that can be cleaned or does it need a whole sending unit with another pump? I already spent the $100 for the pump, and it is working if you can drive it!

My friends 2000(I think) explorer With the 4.0 86k has burnt up two pumps in two weeks. This last one only lasted a day. There was over half a tank of fuel in it when installed and only drove it to work and back, about 50 miles. Next morning he went to leave, nothing. Pump won't run. Checked fuses and relays they were okay. Why would this be happening?

I have a 2000 Ranger with the 3.0. Was wondering where the fuel pressure regulator is located on it. I like pictures.

I have a 2000 Ranger with the 3.0 in it. Trying to find where the fuel injection pressure damper is located. I was told it's on the fuel rail. Just making sure I'm looking at the right thing.

I have a 2000 Ford Explorer with 4.0 SOHC engine, I have had some cold start problems. I cleaned the IAC and the problem went away for a few months and then came back. Two days ago the temps got very cold and it would not start at all, I re-cleaned the IAC and still no start. I replaced the fuel pump with an aftermarket pump and engine started right away. Now I have a rough idle, bad skip and bad exhaust odor. I am still thinking IAC but I am concerned that the aftermarket fuel pump is pumping to high pressure or that I may have crimped the return line. I have driven about 30 miles hoping the computer would make adjustments, still runs rough and the check engine light has not come on.

I replaced the fuel pressure sensor in my freestar...I drove it around for a minute then noticed a strong smell of gas. I stopped and then put the old sensor back in and now it won't start.

I have a 95 Ranger 2.3 with a manual tranny. In the past I have had problems with this truck not starting do to a bad inertia switch and numerous fuel pumps. A couple of weeks ago I pulled the truck off of the driveway into the street and let it set there for a few hours. When I went to put it back on the driveway it would not start. I got it pushed on the side of the garage. I did my normal routine of doing a pressure check. I had no fuel pressure so I assumed that it was the fuel pump (as usual) so I dropped the tank and changed the pump.
I got it back together and it still wouldn't start. I checked the fuel pressure and the manifold still had 0. So I started my diagnostic. I have power from the fuse to the fuel pump relay. I then checked the wiring at the inertia switch and found that there is no voltage with the key on at the supply side of the inertia wiring. I verified continuity between power distribution block and the inertia switch. I put in a new fuel pump relay and it still has no fuel rail pressure and there still is no electric signal at the inertia switch. Where to go from here?

2001 Ranger, 108,000 miles, good regular maintenance per the Ford Schedule. 4.0L manual trans.
I changed the fuel filter 20,000 miles ago. This has been a recurring issue anytime my fuel level was low, about 1/4 tank or less, and when the truck was warmed up, hot. The fix in the past was to add fuel and let the truck sit for awhile. Now, today I drove home for lunch and when I tried to start the truck to return to work, it wouldn't start.
Same conditions, low fuel level and it was warmed up. The engine will turn over and start to run with ether in the air box, so it's definitely fuel related. A fuel pressure gauge on the Schrader valve got a zero reading, not even a flicker, and no residual pressure after shut off.
Could this be only a fuel pressure regulator issue? Or should I prepare to replace the fuel pump? Is there a fuse that might be blown?

Hard start like it's not getting enough fuel then kicks in and runs great with no hesitations or issues and with plenty of power. Replaced fuel filter, nothing changed.

Ok so I have a 1997 Ford Explorer with the 4.0 SOHC .. The girl that owns it went out and started it to warm up and went back in the house , when she came back out it had died and wouldn't start .. I hauled to our shop and started diagnosing it .
It has spark
has fuel
Timing is good
Fuel pressure regulator is good
Crank sensor is good
About 62 PSI fuel pressure
No CEL
Seems to be getting WAY too much fuel and fouling plugs !
Replaced ECM ...same thing .
Used NOID light on injector wire and I have never seen one get so bright !

Sons 94 ranger 4.0 4x4 Auto 185k got him to work yesterday but would not start to bring him home. No spark, checked with timing light, and no fuel pressure. Searched and read alot of tips from Pawpaw so I tried a few things with no luck. Swapped the relays around, inspected coil pack and plugs. CEL was not on and goes out while cranking. I have a OBD scan tool but this truck must be too old or I need finding plug. Crank sensor maybe?

My parent's bought a 2002 Explorer 4.0 V6 very early, either late '01 or early '02 when it first came out. Besides the dash blackout (which I found a fix for, need to do) it's been plauged latley (since Nov/Dec 2010) with the intermittent issue of when... You turn the key on to start, you dont hear the fuel pump enguage, thus no start. Get towed, it works like a champ.
It's blown a fuse 1 or 2 times cause of this, had the fuel pump recently replaced (dec/jan this year) and just did it again. Our local Ford dealership figured the fuel pump went bad from sitting, the vehicle only has about 33k miles on it (dad dont drive much). What appears to be a bad fuel pump, only to have it get towed, or sit overnight and start like nothing ever happened?
Dad's ranting about not trusting the vehicle anymore, he's 80yrs old so I can't blame him for wanting to feel comfortable with knowing his vehicle should start, but it is a machine, they do break but we cant seem to get this fixed.

I need to check the fuel pressure to verify if my fuel pump is functioning. What is the procedure and PSI?
Assume that I open the valve on fuel rail with engine off, then connect pressure tester kit, put key in ignition to "on" position, then pump up to specified PSI???

I am new to the FTE world but not to diesels my 2012 f350 is my second diesel and a couple weeks ago I got home from work and fell asleep and forgot to plug in my pickup and it gelled up (was about 15degrees when I fell asleep and -20 when I woke up) so all the filters were replaced and everything was good after that for about a week, then my fass platinum pump started blowing the 30a fuse every 10 seconds and The pump itself smelled burnt so I replaced it with the same style and size of pump and the pump is good now but the truck is a no start it has thrown codes p2291, p0089, p0091, and p228e. It has 4inch straight exhaust, fully deleted (def and egr), h&s tuned, fass platinum 125 lift pump.

Made a trip to the hardware store yesterday. When I came out, the truck would crank just fine, but wouldn't start (98 4.0L 4x4). Tried adding gas, no luck. I had actually called a wrecker, but it eventually started after sitting for about an hour. All I did differently was hit the gas pedal a couple of times. Thinking it may be a low fuel pressure problem, I took it to autozone this morning (started it about 4 times now with no problems). Checked the fuel pressure, and it sat at a solid 65 lbs at idle. I tried holding the throttle open and it stayed at the same pressure. I forgot to try with the vacuum off.
First off, I've seen some people say 60 lbs is right, but more say it should be at about 45lbs. 45 seems right since the fuel return is on the block, not on the pump. I'm guessing the fuel damper went out, but is there any good way to check it? Also, since the damper is vacuum controlled, would a bad vacuum cause this problem? Third, could high fuel pressure cause it to not start? That's the one I'm most worried about what was wrong there.
