#109 of 302 2002 Ranger Engine question by rangergirlie

Aug 21, 2007 (3:58 pm)

Hey, I bought my ranger in 2005 with it being an 02 model and I have a question about the engine. well, I've noticed at the beginning of the year that it's not getting the right amount of mileage that it should be. I think it's suppose to be getting around 300 to the tank, but now it's more like 230 at max. Also, since it's been making clanking noises when i would accelerate, I had to switch to mild-grade on the gas (and it helps), but I'm not sure if they are related.
But, right now it's at the ford dealership getting warrenty work on the aircondition. I have extended service plan so i don't know if maybe some of the engine problems will be with the warrenty.
but if anyone has an ideas, let me know please. I just want my truck to be fixed so i can move on.

You have the 3Liter V6, right?
 
They ping. This is what you are hearing. Higher grade of gas is about only thing to help with this.

Yeah it's a 3.0L V6. I know the pinging noise will go away with using the medium grade gas. But with using that type of gas, is it normal to lose a little gas mileage??

I would have thought it might give better milage.
 
But if you are not writting milages down and carefully calculating each fillup, your milage figures are useless.
 
Such as 'I get xxx miles on a tank of gas!'
 
My 94 4Liter with a cap got about 14 in town and the highest I ever saw was 18.5 on highway driving. I now have a Honda Ridgeline which gets 19-20mpg on the highway and is a much larger, 4wheel drive truck.

How do you figure highway and city driving mileage? I would think that you divide the mileage by the amount of gallons used at fillup. Unless of course you have a computer that tells you your current mpg as you drive. Even then to state 18.5 highway? How accurate can that be?

I do it the way you said, which is the correct way to do in. Every car of mine has a small notepad where each fillup and its milage is logged.
 
I've seen lots of postings where people say "My whatsit used to get 300 miles to a tank it now only gets 275. What is wrong with it?" This isn't a milage calculation.

#115 of 302 hard starting 2002 ranger by rbd008

I have a 2002 Ranger V6 3.0L that has suddenly become hard to start. I replaced plugs, checked hoses and replaced the IAC valve but still no change. Any suggestions?

Does it start ok when hot? If so, the following may be the problem.
 
You probably have two temperature sensors. One drives the guage on the dash.
 
The other talks to the computer and gives it the coolant temperature. This one has possibly failed. It is not telling the computer that the engine is cold. Under cold starting conditions, the computer increase the fuel amount injected (unriches the mixture). If this enrichment is not done, it will be hard to start.
 
This sensor will usually have black and yellow wires, twisted together, coming off it.
 
Or, your fuel pump may be failing and is not giving enough pressure to start. I would think this would cause other problem, like missing at high speed due to fuel starvation. A pressure guage on the schrader valve on the fuel injector line should give the pressure readings. I don't know exactly what they should be, but around 40lbs, I think, is usually in the range of a good working fuel pump. The fuel pump is inside the gas tank.
 
Or, you might just have a clogged fuel filter, if you have a lot of miles and it's never been changed. Or you got a tank of dirty gas.
 
I don't think the IAC valve has anything to do with starting, only idle speed.

I'd also change the wires if you're still running the original. Not that it has anything to do with a hard start. Just that with the engine comparment temp the wires deteriorate and at 5 years would be a good idea to replace along with the plugs.

My ranger has starting problems even when warm. I have to crank it usually 3 time before it starts. I see where the coolant temp sensor is next to the thermostat. But, if there is a 2nd sensor where would it be located? It runs fine after starting. The fuel filter was supposedly changed about 3000 miles ago during my last oil change by "Jiffy Lube"
