Having an intermittent strange sound coming from the fuel pump from its normal whine at start up to a gurgling sound almost like you are blowing back through the fuel line back into the tank. Going on a 300 mile trip, should I hold off?
Btw: it's a 1996 Aerostar 3.0L
Intermittent fuel pump problems in '96 Dodge ram resulted in new fuel pump 50,000 miles ago. Happened again 100 miles ago, so another new fuel pump. Now to start car must turn the ignition on several times before going to the start position. It appears the latest new pump may have defective one way check valve, so the pressure is depleting after turn off. Any favorite brand of fuel pump for the Dodge "pump in the gas tank" arrangement? Or solutions such as installing an external pump to do the work of pumping the fuel?
View 1 RepliesIt doesn't happen all of the time and it's not consistent as to when it occurs. Originally, I thought it happened when it was cold outside, but since it's been pretty cold here lately, I have not heard it. Also, it has occurred when the engine was warm (after driving for 20 min or so).
It sounds like it's coming from the engine block, but I'm not 100% sure. I have a 1996 ford explorer 6 cylinder 4.0L engine with approx 249,000 miles.
I seem to remember a old post but I can't find it! Someone replaced the fuel pump by cutting a hole through the floor.

I got a code for Fuel pump secondary circuit failure, how do you fix it? 1990 Aerostar 4.0 2wd with A/T and A/C
View 14 RepliesMy issue. 95 short Aerostar, Vulcan engine, A4LD trans. Just got it last week. Bought a new trans and when I went to pull the van into the shop, it wouldn't start. Cranks but won't run. First thing I checked is fuel pressure, got zero. Pulled the kick panel and found the inertia switch, but the harness for the switch is getting 1.8 volts with the key in "ON" and the same with it in "START". IIRC it should be zero in RUN after a second or two (if the engine isn't actually running, that is), and 14 in START.
Checked all fuses in the panel by the steering column, they're good, and switched around the 3 relays by the battery. No good and I don't hear the FP relay when I turn the key. For now I'll run wires directly from the battery to the pump, just til I get the trans done, but it needs to be fixed anyway because I plan to make this van a DD. Here are my questions:
-Is there a second fuse panel I didn't find?
-Could this be a computer issue? If it is, would the computer fuse be blown?
My 96 4wd 4.0 Auto has a consistent misfire in the #6 cylinder. I've change out the plugs and wires and am considering changing the fuel injector for that cylinder. Looking it over last night, got me wondering if there is a way to change out the fuel injector without removing the upper intake manifold and the entire fuel rail. As you all know, these things are a beast to work on when the engine is in place. So, is it possible? Inquiring minds want to know (and don't want to spend an entire weekend changing out on fuel injector if there is an easier way )
View 14 RepliesIs it normal in these vans to here the fuel pump humming? I hear it when I turn the key on and while I am driving. It never gets quiet.
View 3 RepliesI've owned this vehicle since new and never overheated or had any major mechanical issues. It just hit 130,000 miles and recently completed a 1500 mile uneventful road trip running great.
The other day I noticed an excessive amount of steam/smoke coming from the exhaust while sitting at a stop light after recently starting the vehicle. Once the van was up to temperature the exhaust steam/smoke cleared up.
I checked the radiator level and found it was about a qt low, and did not seem to have any exhaust bubbling or fumes in the radiator.
Then, I pulled the dipstick and the freshly changed oil looked a bit cloudy (I got really nervous), I really can't say its milky colored because I can still see though the oil and see the cross hatches on the stick. But it doesn't look like new oil.
The engine seems to be running fine, no loss of power or missing. Starts and idles fine.
Talked with a mechanic friend and he immediately said blown head gasket or intake manifold was allowing water from one of the four corners where the gasket seals the water jacket, into a cylinder.
Since that first episode of excessive steam/smoke it hasn't reproduced the problem to that degree. It does start to steam out the exhaust after about 5 minutes of starting cold, but seems to dissipate after the engine warms.
The amount of smoke / steam in that first episode, I couldn't see the car behind me in the mirror ... I looked like a mosquito fogger.
I have a 2000 V70/XC volvo with 95K miles. I began hearing a strange hollow noise, like a whistle blowing. I took it to the dealership where I bought the car and they said it was the fuel pump. I asked them if it was bad and needed to be replaced and the said they weren't sure about having it replaced right away. They said sometimes it will make that noise and the fuel pump could last for months and sometimes for years. They even suggested to just drive it until it fails then replace it. some say it could never go out. But it bothers me because it is the car that my wife drives daily taking kids around and running errands and so forth. I am always worried that she could get stuck somewhere anytime. So I am not sure what to do.

I read about the fuel pump relay, so since I am not made of money, I decided to change that first ($16 vs. $100). After installing the new relay, the truck started! I put the old relay in the box and tossed it into the glove box.
After lunch, and some thought, i decided I wanted to put the old relay back in and see what happened. Guess what! It started with the old relay as well! I also noticed that the humming/buzzing sound the fuel pump makes when the switch is turned on was different with the new relay vs the old one. I put the new relay back in, but now I am unsure where my real problem lies. Intermittent relay, or fuel pump on its way out??

View 2 RepliesI've got a strange sound coming from the front axle. I want to rule out/in that it may be my auto lock hubs. Can I slide the hubs out and drive around? I dont see any problem I won't be offroad, just some miles to test it.
View 1 RepliesThe other morning I went out to the garage and heard a strange noise coming from the rear (underneath the 3rd row seating/storage area) of my GX460. It sounded like a pump or something running continuously. I was in the garage for 10 minutes and the noise had started before I entered the garage and continued after I left. When I went back out to the garage 3-4 hours later it had stopped so I am not certain how long it was running for. I previously owned a 2006 GX470 with the rear air suspension and this was not the sound that was coming from my new GX. The car had not been running or driven in over 8 hours and I am at a loss as to what it could be. I figured I would check here first before delving into the 700+ page owners manual to troubleshoot.
View 9 RepliesI was letting my truck idle to work on a cooling issue when I noticed oil coming from my fuel pump! What would cause this? It wasn't coming from were the pump bolts to the timing cover it was coming out of the side of the pump it looked like? I'm going to get a new one.
View 7 RepliesWorking on my cousin's 84 F150 351w HO with a Holley 4180 4bbl and auto trans.
I rebuilt the carb because of sticking floats (that and it was filthy and sitting). It fired up and I drove it to my uncle's shop a ways down the road before even adjusting anything. At the shop, it fires right up, idles great and floats and idle mixture screws are now adjusted.
It has a dead spot right off of idle that's been driving me crazy, and stalls in gear if I'm not careful with the pedal.
After reading around here, I looked down the carb to make sure the fuel was squirting as soon as the throttle moved, and noticed there was NO FUEL squirting from the nozzles. So that explains the dead spot...
There was just the needle, then the nozzles, then the screw that went in, same as they came out (only cleaner). Wondering where to go from here to get these working again. Going to pull the nozzles off and see if there's anything obvious going on in there.
My 09 FX4 Screw has developed a strange thumping sound coming from the undercarriage within the last month or so. Very noticeable when turning on even terrain. It's just barely under warranty and I am planning on taking it to the dealer.
View 2 RepliesMy father in law has an 04 EX with the 5.4. It has a weird sound coming from the front passenger side. He listened to the jiffy lube kid who told him it was the brakes. I pulled one side completely apart tonight and the brakes are fine. We took it for a drive so I could hear the noise. It is coming from the passenger side up front. It is intermittent.
Doesn't matter if we hit a bump or pot hole. It sounds like a cat being run over. It will either last for a few seconds or just really quick. I crawled underneath and could not find anything loose. The first time I heard it I thought it was a shock. But the second time it was way too long to be a shock. And they are only a year old.
Secondly, it has a cat, and two mufflers..... Is this normal?

I've got a strange squeal sound coming from under the hood only when truck is cold? It sounds like a bearing and after it gets heated up the sound stops. I talked with a guy thats a cummins guy and he said he had a similar issue and he had to replace the bearing in the turbo? Also when truck is warm it will still do it, like for instance, if I run in a store and truck idles for 5-10 mins it will do it only if I romp on it for a short while like 2-3 mins then again goes away. And if I'm idling or in neutral, hot/cold, it does not do it, it seems to be only under a load. Pull a 26 foot boat no problems.
What could be making the strange pumping sound coming from under my hood after I shut off the truck?? It sounds like a small compressor or pump running.
