Ford - Explorer :: 1994 - Crank But Won't Start - Fuel Pump Relay?
Sometimes after running my 94 Limited, it doesn't want to start - it does crank - like it's not getting fuel. I have found the work around and want to know if it would be fixed by replacing the fuel pump relay.
The symptom is just after starting, it starts to run poorly, and then dies out, then will not start at all. I use to keep trying to start it for 20-40 minutes and suddenly it seemed to work.
It seems the work around is to turn the key to on for about 5 seconds and then turn it off - then it starts and runs as good as ever.
So, is this a symptom of a bad relay? I thought I'd start there because of the cost of the relay is fairly cheap. 1994 Explorer Limited 4x4?
Ford - Explorer :: 1995 - Replaced Fuel Pump / Filter / Pressure Regulator / Crank Position Sensor But Won't Start?
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.

I own a 2003 Limited with the 6.8 V10. I drove the truck on Sunday and all appeared to be fine, gas gauge was setting just under a half tank. When I went to start it yesterday, it would not start. Strong crank, no start. I checked my fuse and it was fine. Fast forward to this morning, since I had kind of depleted the battery with attempting to start, I put my little jump start pack on it and gave it a whirl. Truck started fine but the gas gauge was sitting on empty. I had five gallons of gas in the garage so I added that to the tank then drove to the local gas station to add more fuel. I put another 10 gallons in the tank so it should have roughly 16 or 17 gallons in the tank. Gauge shows 3/4 tank but miles to empty is right around 175 miles which would seem right with 17 gallons in the tank. I suspect the fuel pump. I don't really want to spend $500 on the Motorcraft unit but was wondering if the group believes the Delphi or the Bosch units are quality replacement parts?
View 7 RepliesFord Excursion :: Bad Fuel Pump Relay / Fuse Panel Replacement?
- Fuse Box - Part # 3C7T-14A067-DC Engineering Number on white label.
- Ford Dealer Part # 3C7Z-14A068-DB
I have a 2004 Ford Excursion 6.8L 4x4 that has a bad fuel pump relay. I am looking for a used replacement fuse panel.
Of all these number and letters which of them tells me the real part number? Does the last two letters mean anything "DC" or "DB"?
So I don't get one for a diesel, what is the prefix for the diesel? I am assuming the 3C7T is gas and the year model?
Also, will this fuse panel interchange with a F250/F350 6.8L or do I need to stick with a fuse panel from an Excursion?
Ford Ranger / B-Series :: 2003 Turns Over But Won't Crank After Fuel Pump Replaced

2000 excursion V-10. I parked the truck, went back to start it and all my gauges blink, and the number one relay under the dash (interior light relay) begins clicking. The truck will not even crank. The relay will continue clicking (even with the key off) until you remove and replace the relay. Sometimes I will get absolutely nothing when I turn the key. I have tried jumping the battery, no change. Also tried starting it in neutral to trouble shoot the NSS, but it won't even click when in neutral. I checked battery connection, and followed the battery cables to look for a short but found nothing.

1999 4.6L won't start after sitting a month. Ran fine before, now won't start. Cranks fine. Cannot hear fuel pump turn on when key is turned. Fuel pump fuse is good.
Fuel pump relay clicks a few times when key is turned. Is this normal? I am hoping it is the relay and not the pump. What should I check next? The wires at the pump? What should they read?
Ford Super Duty (1999-2016) :: F250 5.4L - Engine Won't Start / Fuel Pump Relay Failed
I see several threads regarding engines that wont start for no apparent reason. My reason was a failed fuel pump relay. This sucker is hidden in the dash below and to the left of the radio. I got to it by taking out the ash tray. There are three relays under the cover. The upper left is the fuel pump relay. The one to the right is the turn signal relay. I don't know what the bottom left is for.
View 3 RepliesTrans Sport :: 1996 3.4L Van - No Start Intermittently / Fuel Pump Relay Chattering
I have a 1996 Pontiac Trans Sport 3.4L (without Passkey anti-theft) which on occasion won't start after being parked. The fault only happens when the vehicle has been sitting, it does not die while being driven (so far). The engine cranks normally but does not fire. The peculiar and significant thing about the fault is that the fuel pump relay (driven directly by the PCM), chatters at about a 10 Hz rate. Instead of receiving a steady 12VDC to keep it energized, it is receiving a pulse stream from the PCM.
The first few times this occurred, I heard the relay "chattering " under the hood , and was able to start the van by unplugging the relay and shorting the connector terminals for the contacts together with a wire jumper ( these terminals connect "hot at all times" 12VDC from the PCM fuse (orange wire) through the relay contacts to the fuel pump +ve). The electric pump would run and I could start the engine easily. By the time I arrived at my destination, the fuel pump relay 'drive' would be normal and I could plug the relay back in and continue normal operation.
The last few times this problem occurred, the van would not fire -- no spark as long as the relay drive was pulsing. When it would finally go back to normal operation of the relay, the engine would start OK.
Last Spring in cold weather I had the van towed 2 blocks to a Pontiac dealer with this problem. The problem resolved before they inspected it; however after the Technician's inspection the Service Advisor said there was no fuel pressure at the test port and that the pump must be deffective (shorted), overloading the relay causing it to chatter. That diagnosis made no sense to me. They wanted to replace the fuel pump as the solution ($600). I got past the Service Advisor and asked the mechanic to show me the fuel pressure -- the car started on the hoist when I tried it, and fuel pressure was normal (>30psi). I left with just the relay changed, as they thought the original would have burned -up contacts from excessive current to the pump. (I cut it open later and found its' contacts to be perfect). While at the dealership I asked the S.A. if he knew of any TSBs, or other incidences of this problem; he said he had not heard of this problem before.
I had the same problem one week later, but not again all summer until this Fall's cold and wet weather. I had to have the vehicle towed home and it still wouldn't start the next day. As soon as I accessed the PCM behind the glove box and jiggled it the relay chattering stopped and car could start. However, later the same day, still in the driveway, the fault was back and no amount of jiggling or other manipulations had any effect. Later still I went out to test for spark, and the fault was gone. (Cold, wet weather all day).
Vibration seems to have little effect. I have checked the PCM connectors' security and pulled, twisted and wiggled the wires coming from it, as mentioned above, to no effect. I suspect the fault is inside the PCM and is thermally induced by cold weather. The next time it happens I will try a warm hair dryer on the aluminum housing of the PCM. I wonder if there is a fix for this (repair a cracked solder joint, etc.) other than replacing the PCM. I work in electronics, and will open the PCM up and inspect it before forking out for a new one.
Ford - Explorer :: Loss Of Power To Fuel Pump / Crank But No Start
I have an 04 Ford Explorer XLT 4.0 Flex Fuel. There has been loss of power to fuel pump. Relay and fuse both good, replaced the inertia switch...still nothing. Could a FPDM (fuel pump driver module) have anything to do with this issue? Or what should I check next? I am definitely at a loss as to what the issue could be! I know it is fuel related because I used starting fluid and it started right up and run for just a few seconds, so that should rule out ignition I think.

View 2 RepliesFord Excursion :: Won't Start - Fuel Pump?
Before I left on Spring Break last week, truck wouldn't start. It was a Saturday morning, so I had it towed to the only open shop in town. He said the fuel pump was going out. He got it started maximizing the fuel pressure with his scan tool.
The unusual thing is I replaced the fuel pump (I have a V-10) earlier this year with a Motorcraft Pump from Amazon. I also replaced the fuel filter about 60,000 miles ago.
Does this sound right? I have never heard of turning up the pump with a scan tool.
It did fine over Spring Break, but is in my driveway right now refusing to start. I can't believe the fuel pump went out that quickly.
Does it sound like the fuel pump?
Trans Sport :: 1992 Pontiac 3.1L V6 TBI Engine Refused To Start / Fuel Pump Relay Error Code
We have a '92 Pontiac Trans Sport with a 3.1L V6 TBI engine. Last Sunday evening it refused to start like someone left the transmission in Drive and the Park/Neutral switch was preventing it to start. There's the buzz sound from the fuel pump when you put the key on then nothing when you turn it to start the engine.
I checked the Park/Neutral swith by connecting an ALDL cable to the OBD port and it indicates correctly when I move the lever to Drive or Parking/Neutral. The only error code stored is "Fuel Pump Relay" but the Fuel Pump appear to be working?!
Battery is good, fuel pump fuse intact and the Park/Neutral switch appear to be working. How we can tackle this problem?
Ford 7.3L Power Stroke (1999-2003) :: 2002 7.3L Will Crank Forever But No Start (bad Fuel Pump)
I just got delivered a 7.3L from down south. Batteries were dead so replaced both. Fuel was a couple notches above red line (much closer to red line than 1/4 tank) so I added about 7-8 gallons.
It will crank forever and ever...Won't start.
With starter fluid it starts but not strong enough to pump the pedal and rev it up to keep it idling.
I know s-fluid is bad but if I continuously spray with key turned forward it will run but as soon as I let go of key it shuts off.
20 degree weather and it was delivered to a parking lot so I cannot plug it in.
Was told to check filter cap, turn key, and see if it fills bowl with fuel....if not then it is fuel pump. Someone else mentioned that it could be bad crank position sensor? Does this sound like fuel pump?

View 13 RepliesFord Excursion :: Start Then Die Immediately - Fuel Pump?
As in a previous post, i have been having issues with my truck starting then immediately dieing if i dont keep my foot on the gas.
Ive learned how to drive with 2 feet because of it, but I'm afraid i might be doing some type of damage since it keeps dieing and I have to keep starting it.
Once i get going for about 10-15 minutes its fine but its happening every time i start the truck.
Before it starts running correctly, it only idles around 400 rpm.
I think its the fuel pump, since my mechanic put a code scanner on there and it didn't throw any codes, he thinks it might be the fuel pump.
My question is, should i go with a ford pump from the dealer or are the ones sold from discount/o'reilly/napa just as good?
Saturn - Vue :: Crank Then Start After 5 Minutes - Fuel Pump?
vue would crank, not start. 5 min later it started. done this 3 times in 1 month. changed original fuel filter. am leaning towards fuel. vs spark. no codes. I see pump assy's for $175. or a pump alone for $30. if I remove tank and pump assy, would there be any issue with changing pump alone? not paying shop so its my effort the last gm pump assy I did had a working pump but corrosion on leads to pump inside tank. I replaced assy because I had already bought assy.
