Okay, I have a 98 ford ranger L4 2.5 liter. Believe it or not this baby has 180,000 miles on it and has always run like a dream...until lately...

When I reach higher speeds, usually around 40 mph, the truck is acting very sluggish. The more I push on the gas, the slower it wants to go, it will barely go up a hill on the highway, and the acceleration is completely non-existent unless going down a hill.

I think it might be the fuel pump...but I have no definate idea...Please help!

PS- where the f*** is the fuel pump on this thing anyway???

If it is fuel pump, you should have check engine light on and code reader would read 171 and 174 code.
Anyway, the fuel pump is in the fuel tank. The manual says you need to drop a fuel tank to get to it. I've got a better idea, I just take the truck bed off (get a good torx socket and a breaker bar from autoparts store... it's not a big deal... 4 bolts, get a couple of muscleguy neighbors and it comes right off). Then, the fuel pump is right there. You can drop down the fuel tank to hose it down and stuff, still easier with truck bed out to suckout the rest of fuel and workout rusty straps. Good luck!

Schaste, I had the exact same problem. Mine was worn spark plugs. NOT an easy thing to change on these trucks. I ended up having a mechanic do it.

I have a 1999 ford ranger, it will not idle unless you give it some gas with the pedal and even then it's very rough running. It will not power up a hill heck not even enough to move much on the flat. I have a fuel pressure gauge, what should it read? Could mine also be a spark plug issue?

Joe, in your case it's IAC. It sits on intake manifold bolted with two bolts with wire sticking out of it. OR it could be any vacuum leak in intake manifold. Get youself a vacuum gauge (harbour freight sells 'em cheap) and check for idle vacuum. If it's low, you gotta snoop for leak. If the vacuum is good, then you IAC is toast. Go get the new IAC (any autopart place sell them, they ain't too bad). Changing that thing is easy: just unplug that wire, unscrew two bolts - and off it goes.

BTW, fuel gauge should read around 60 psi after key on, and it may drop to upper 40 low 50 with engine on.

My 1998 Ford Ranger was running fine, until I got custom work done to it. “Air bags, suspension”. The Ranger will crank but it is not getting any gas. The fuel pump and cylinders are not working. If I give the pump direct power it works. All fuses have been checked. The Ranger will start with starter fluid for a couple of seconds then die. It has no alarm. The gas tank was never dropped. So it has to be something that controls the gas pump and cylinders.

Alan, check the fuel pump shutoff inertia switch. It's right at the passenger side where the legs go to the right. Just pull that plastic trim thing right off, it ain't screwd. The switch is that black thing with button on top behing the carpet end. The airbag control unit is right next to it, and I can see that whoever did airbag job could mess it up.

I have a 1998 Ranger one thing everyone seems to overlook is fuel pressure. Throw a pressure gauge on the fuel rail if its around 32-36 psi your good if its up around 62+ psi your have a bad fuel pressure Dampener. If the pressure is good at idle then drops on acceleration then its the fuel pump or clogged fuel filter. There is also the possibility of a plug exhaust system.

I have a couple questions regarding my 1999 Ranger Splash 4.0 V6 with 85k original miles.

First: For a couple months now it's been having some pretty bad engine sputter when driving and idling. I was told that it can be as simple as putting new plugs in even though my motorcraft plugs are only 18 months old. Or it could be a head gasket problem. The sputtering feels like all of a sudden there's no gas going to the engine for a moment and then it goes away, but does this consistently whenever I drive my truck.

Second: How the heck do I remove my fuel filter? I couldn't figure it out for the life of me. I hear that there's a "special" tool for the job, but wasn't sure if it was necessary or not.

And finally: Is changing my fuel pump as big and expensive of a job as it sounds? I've heard a lot of stuff. From pulling your bed off to get to your tank to just dropping your tank to get at it.

Thanks.

I have a 1999 ford ranger that has been sitting for 2 or 3 years. I finly desided to get it running theother day . i put a battery and new plugs in it and it wont start it sounds like it wants to turn over but its not getting any fuel. I talked to a ford mechanic and he said it's probly the fuel pump gummed up he told me to add gas and let it sit for awile and it should loosen up. will this work or is thear a way to clean the fuel pump without removing it from the tank??

To tell for shure if it is fuel pump, measure fuel pressure on the fuel rail (shraeder valve below intake manifold, similar to tire valve). Loan the pressure gauge for free from autozone. Should be 55 psi+.

For me, it's easier to lift the truck bed off to get access to fuel pump. You just unbolt 4 bolts and fuel filler neck and disconnect wire harness. You need at least 2 helpers with good backs (I use my neibors for beer). I'll say one more time, if you replace fuel pump - get OEM bosch (can find cheap on internet). Aftermarkets are all junk (our pump is high pressure one with built in pressure regulator).

To change the fuel filter you indeed need a special tool. Fortunately, it's a cheap one, around 5 bucks in any part store. Use the same tool to disconnect fuel lines at the pump too.

There is no way to clean fuel pump. It's got small (1mm) rubber ball with tiny spring as pressure regulator. Once it's stuck - it's stuck for good. Not a very good design, however, allows Ford to skimp on return fuel line. No wonder they are in trouble, cheap bastards.
