Is there a relay between the Fuel pump driver module in the trunk behind the rear seat and the fuel pump? I can pull the plug from the FPDM and jump from there if there is not a relay between the FPDM and the pump unless there is a better place to jump 12v from.
Just want to post this thread maybe to help someone out there save a few dollars. My neighbor's 05 4.6L died in the driveway the other day. Read a few threads bout the FPDM thought we'd take a look. To our surprise we found a broken module. Got one on Amazon for $53. The local parts stored wanted $109.
Easy to Replace. All u need is an 8mm socket. Fixed his truck then looked at my 07 5.4L found mine was about to break also. They corrode really bad on the back side. So I used 2 rubber spacers to get it off the frame. Seems to be fine. If ur fuel pump stops working.
Look here first. Also all owners might want to look at theirs maybe to prevent being stranded!!!! My father in law is chasing a start-no start condition. It's very cold at the cabin, 20-30F below is fairly common and he feels there was some water in his last fill up.
He fired it up and it ran for a minute or two and stalled. He put an electric heater under the filter and covered the truck with a tarp for a full day. It started for a minute then died. He hadn't done the filter in a while, so he decided to change it.
While he was under there and had the lines disconnected, he turned the key to see if any fuel would come out of the line from the tank and nothing came out. He put the new filter in and tried to start it.it fired up and ran for 5 minutes. He tried to blip the throttle and it stalled then wouldn't restart. No garage and it's a balmy -16F there today at 2PM. He doesn't know why the pump would not run with the filter disconnected. He's probably going to do the FPDM because it's easier and cheaper than the fuel pump.
For the cost and ease of replacing the module, everyone should blindly order one, and replace it ASAP! Mine crapped out on Jan 16th.
I filled up my truck with gas the night before, and on the way home it 'coughed' and sort of backfired once. I ignored it, figured the trans was cold or something, it is winter here. The next morning, I was driving to work (44km /28mi) commute, and half way there, my truck started to buck and chug violently, like the trans was popping out of gear. I shifted it in and out of OD and it did it just fine, so that meant it was an engine issue.
There is a Ford Stealership near my work about 3kms away, so I pulled off the freeway near there because I was having a hard time maintaining speed. Could barely do 80km/h, it was gonna die any second.
When I got near the dealership, i tried to push the truck to make it to work, but at this point it wouldnt even accelerate and was barely running. With the temp being so cold, I chickened out and limped it to the dealer.
Left it with them. They charged me the flat fee to diagnose, 1.5hrs labor, cost of computer, and the stealership hidden fees for a total of $650!!!!!!
I went for it, because the cost of the tow home, the cold outside, etc etc I couldnt afford to have the truck down for so long. So save yourself the money and just replace the stupid thing! Imagine someone switching your fuel pump on and off while driving, thats exactly how this felt. It shudders the truck violently, and is probably really bad for the driveline. Fun fact, the newer ones are coated and are supposed to be more dureable. Isolating it with rubber is the smart thing to do. Almost 100% of all this years trucks are gonna fail.
Be wise and listen to the people who have experienced this issue and fix or replace yours soon.Yeah, maybe so if left unattended and not fixed in time and if the truck otherwise last and last? But if caught early enough, no reason to believe it'll fail. Many continued to work after the interior was opened to the elements through corrosion.
Back in January 2010 or 2011 I had just returned the night before from a 1200 mile round trip to visit family for Christmas in Ga and next AM I was on the web surfing and saw a thread about FPDMs. It being a decent day, I decided to look at mine that day. Mine was starting to corrode where the aluminum rests against the steel frame member. More importantly, I also found where some critter had chewed the wires and one wire had maybe 2 strands left, the chewed ends stabbed my finger is how I found it. I fixed the wire with some short splices, solder, etc.
A permanent fix. And darn happy it had not broken the day before hundreds of miles from home. I also sanded the back of my FPDM and coated it with several coats of clear enamel.
And I took some longer metric bolts, cut the heads off to make long studs. And used lock nuts as spacers and some washers to space the FPDM a gfood 1/4' off the frame to stop corrosion. I also cleaned and painted the frame where it mounted. Here's a pic after I remounted the FPDM with stand offs in place, I added the zip tie.
I have not yet fixed the wire however when I took this pic, it was the blue wire that something ate into. It's well protected now. As well as the fuel lines and return lines I also fixed not long afterwards.
From an older post on forum about fuel pump relay, 11:39 #1 (permalink) KT3A33B Registered User Join Date: Jul 2007 Posts: 3 98 ZX2 Fuel pump relay location? - Hey guys, I'm trying to fix my sisters car and I can't find the location of the relay for the fuel pump. I've looked under the hood, under the dash, by the ECM, under the rear seats, and I can't find it anywhere. This is the first time I've ever worked on this car so I'm kind of clueless. If you a could help me out in any way, I'd really appreciate it. Thanks Kevin., 15:57 #2 (permalink) madeline8833 Registered User Join Date: Jul 2007 Posts: 6 Re: 98 ZX2 Fuel pump relay location?
- So no one ever answered ya huh??? I'm kind of having the same problem. I have a 2002 escort ZX2, and I killed it in a flood we had here in Pueblo, Co a week and a half ago.
Well my car works, but there's not enough power going to the fuel pump to get the fuel flowing to my engine. You don't what to know how we figured it out, but we're trying to find the fuel pump relay on the car to check that, and we can't for the life of us find it! We checked everywhere you have! So if anyone looks at this and knows anything about it!! I'm not sure it would be in the same place as the 98, but it's worth the look!! Posts: 3 Re: 98 ZX2 Fuel pump relay location? - I was told at the dealer that they don't show a fuel pump relay for that car.
I guess it's back to the drawing board., 17:22 #4 (permalink) madeline8833 Registered User Join Date: Jul 2007 Posts: 6 Re: 98 ZX2 Fuel pump relay location? - see I called the dealer too and they said that there's a box full of relays that costs about 205 dollars to replace, and if one goes out you have to replace them all because they're all in the same box, but auto zone sells the fuel pump relay for my car for 6 dollars and checker sells it for 20 so I have no idea. Now my friend that's helping me work on my car says he thinks he knows where this box of relays are that they're under the injectors, so we're going to check that out, and hopfully that's it, and I don't have to replace all of them cause that's almost a whole car payment. =), 06:12 #5 (permalink) sergeantkyle Registered User Join Date: Aug 2007 Posts: 5 Re: 98 ZX2 Fuel pump relay location? - Oh please tell me if you have found this relay box.
I seemed to have shorted out the fuel injection system somewhere and it keeps popping the fuse under the hood as soon as i put a new one in. Thanks, Kyle, 20:38 #6 (permalink) madeline8833 Registered User Join Date: Jul 2007 Posts: 6 Re: 98 ZX2 Fuel pump relay location? - Well yes I found it there's a little black box under the air intake by the fuses, but not in the fuses. That box is full of all the relays. What I did to my car was when the fuel pump relay shorted out it fried the motherboard that all the relays plugged into.
So, that kind of sucks because that's going to cost $205 from the dealership, and I have to wait for them to order it. I hope this helps all!!!! Madeline, 21:29 #7 (permalink) sergeantkyle Registered User Join Date: Aug 2007 Posts: 5 Re: 98 ZX2 Fuel pump relay location?
- Looks like i will be doing the same then. I will try to find it at the salvage yard though.
It works for now as long as i dont beat on it. I just need to get by until i can get a new car., 22:28 #8 (permalink) madeline8833 Registered User Join Date: Jul 2007 Posts: 6 Re: 98 ZX2 Fuel pump relay location?
- Beware!!! I figured out what happened to my car. The fuel pump relay shorted out and started a fire in the little black box which is actually called the intergrated relay control module that's what you will be looking for.
At ford they cost $240 at the junk yard they cost $35 in Pueblo, Co that is. I got mine off of a 99 and my car is a 02, so for everyone that has one 99 to 02 the little black box (ircm) is located under the air intake. Yes it is by the fuse box under the hood, but NOT in the fuse box. You can not replace one relay on this car.
If one goes the rest have to be replace, because they are connected to a chip inside the box. Hope this helps!!
