Celica :: 90 Fuel Pump - Can Hear Buzz But No Pressure
I've followed steps 2-6 from this image
I don't feel any pressure in the hose from the fuel filter. I can hear a buzz (guessing its from the fuel pump) but no pressure.
I've checked both fuses, the efi main relay, and swapped out the circuit opening relay with a known good one and all checked out good. Only thing left is the fuel pump or the writing and electrical connectors.
Car has pretty much took a dump one morning and has almost no power. I can't find anything else wrong with this car besides this. Is the fuel pump the problem even though I can hear the pump?
Geo :: 1995 Won't Start - Cannot Hear Fuel Pump Whirring
Geo won't start. It has a new battery and air filter. Just replaced the fuel pump and fuel filter. I don't hear the fuel pump "whirring" when I put the key in the ignition (to on position). All the dashboard lights come on when the car is in on position.
I suspect the relay or the fuse, but having trouble finding the correct one of each. What does the relay look like? i.e. part number? What is the spec for the fuse? 20amp 30 amp? This has been a great car.
Ford - Explorer :: 1995 - Can't Hear The Fuel Pump?
I'm working on one of our fleet vehicles here, a 1995 Explorer. about 2 months back, it stalled out. Got it back to the shop and turned the key on .... I couldn't hear the fuel pump. I replaced the fuel pump and the fuel pump relay. Vehicle started right up and seemed to run O.K. About 2 weeks ago, it stalled out again, same symptoms, acts like it runs out of gas and can't hear fuel pump.So, I have been playing with it and find that it starts up great in the cool mornings. In the afternoon when the temps are hotter, it won't start (can't hear fuel pump). The following morning when temps are cool, it will start right up and can hear the fuel pump. I almost wrote this one off as a defective fuel pump, but I'm not sure on this one.
View 7 RepliesVenture :: 1999 Chevy Will Not Start - Can Hear The Fuel Pump When Turn The Key
Got done with replacing head gaskets and intake gaskets, Van started fine and I backed it out of the garage. Left it running and put down ramps and drove up on them so I could get under and connect the exhaust. Got that done and then got back in it and all it will do is crank and it will not start now. It also has a new cam shaft sensor( wire broke on old one). I can hear the fuel pump when I turn the key. It is like now there is no fire to start it. What could be wrong? What do I check? What causes it to fire? If something was connected wrong, would it have still started and then wont do anything but crank? Got dark on me and started raining so I say tomorrow is another day. I feel it is something simple.

2005 1.8t gti wont start. The other day I was driving on the highway when a thin plastic type wrapping got caught in my serpentine belt. The car immediately died and I hit the gas and nothing and with no power steering i pulled over to the side.
Timing belt was done with water pump and tensioners
Spark plugs and coils are brand new
What fuel line to disconnect to test if the fuel pump works? Like I said in the title I cant hear the fuel pump priming. The engine was running 100% before this 2 techs saw it and the vw dealer i workrd at looked it over.

My wife and i have an 07 accent 2 door and we have a very hard time starting the car after putting fuel in it. Tank level doesn't seem to affect this issue. The car has 160,000 km on it. I've replaced the coil packs already twice. After getting the car to start after putting fuel in it it struggles at idle for the first 15-30 sec and then bang problem is gone until the next time i put fuel in it.

View 3 RepliesAccent MC (2006-11) :: 2007 Hyundai Starting To Oscillate Left And Right
So, I have a 2007 Hyundai Accent MC (1.4, 71kw) and for the past 2 years I have a very strange problem with the car. At first, when I was reaching a 70 km/h (43 mph) the car was starting to oscillate left and right. It isn't a vibration. It's more like a shaking. Also, when I change 1st to 2nd gear, in acceleration, i feel the same symptom, more like a vibration this time.
The oscillation happens between 70-90 kmh (43 - 60 mph). I really can not figure this out. While accelerating it happens the worst.I changed two sets of wheels and 3 sets of tyres. Also, I don't feel the brakes having a problem. While slowing down, I feel no other vibration in my brake pedal, just the one caused by the oscillation.
Sonata NF (2006-10) :: Code P0456 - Cracked Fuel Pump Housing
I have a 2006 Sonata with 88,000 miles on it. Currently, and for the past 11 months, the CEL has been on and the code always returned is a p0456, very small evap leak.
I searched for leaks but couldn't find any. I also replaced the purge control valve, but the same p0456 continues to reappear. Of course I also made sure the gas cap was on tight.
I received a coupon from the dealer for a free diagnostic so I took the car in.
The dealer reported the code as p0455, large evap leak, and said the cause was a cracked fuel pump housing. Cost to repair $850. Seems to me the dealer just picked the most costly part to replace, although I can confirm they looked at it because they forgot to screw the access cover back on.
So what I would like to know is how the dealer would have made such a diagnosis? I cleaned and inspected the outside of the pump and saw no crack, but I also understand that the crack may be too small see.
I want to be able to confirm that the dealer's diagnosis is correct, but how can I do that? I have a hand operated vacuum pump and access to shop air to aid in the diagnosis.
I read elsewhere on this site about pressurizing the system and putting soapy water on the area to show bubbles where the leak is, but where would I connect the air hose? And more importantly, what is a safe pressure to use?
Of course tracking down the cause of p0456. I know the charcoal canister could be problem as well, but I'd like to find some way of isolating down the failing component.
Sonata NF (2006-10) :: 2007 - Fuel Pump Won't Prime
I'm fixing a 2007 Sonata that was in a front end collision, I've replaced everything that was ruined in the wreck (as far as I know), and also replaced the SRS control module, impact sensors, and also the airbag. The car starts with starting fluid and there isn't any damage to the engine so I'm not concerned with something being wrong with that, but the fuel pump won't prime and before the wreck it drove fine. So what could impede the fuel pump from priming? I've checked the wires and they're not sending power to the fuel pump so I feel like the pump should still be fine, it's just it's not getting power. What could cause this?
View 4 RepliesPassat (B5) :: 2001 - Getting Error Code P0343 While Using Scan Tool?
2001.5 1.8t, I have this p0343 code when I used the scan tool at murrays or oreileys whatever the h they are now (it means something like cam angle sensor high input). The t-belt was due for service a while ago , am I looking at a sensor problem or a wiring problem or a timing/engine problem? How should I check and where? I hear the timing belt can be a pain on the 1.8s, I have done a mk4 trans and a bit of other stuff but I do have a lot going on right at the moment and I'm not sure if I have time. I have a feeling if I take it in for service they will probably find blow through from the turbo and pull the engine because of "sludge".
View 2 RepliesGolf IV / Jetta IV :: 2001 - Getting Check Engine Code P0343 And P0321?
I just got a 2001 VW Jetta. I got it with the Check Engine light on. Went to my local AutoZone to get a OBDII reading, got codes P0343 & P0321. P0343 Camshaft Position Sensor A Circuit High Input B1. P0321 Ignition/Distributer Engine Speed Input Circuit Range/Performance. So for P0343 I got the Camshaft Position Sensor for $70 and for P0321 got Crankshaft or Speed Position Sensor for $110 ( FYI, Crankshaft Position Sensor & Speed Sensor are the same ). Paid $160 to get both sensors replaced. I know both sensors are easy to replace but it was easier to pay..

A few days ago code 0496 popped up for evap system problems. The fuel tank is very pressurized and there is a constant bubbling heard in the fuel in the tank with the gas cap removed. Sounds like blowing air through a drink with a straw. I have never had a problem like this with any car in over 45 years.
View 1 RepliesAccent MC (2006-11) :: 2007 GLS - Random / Multiple Misfire And Code P0300
I have a 2007 Hyundai Accent GLS. I just got it from a used car dealership (local) and it runs perfectly. It had a misfire code when i first got it, for all cylinders plus the p0300. It went away when i started the engine again, and didnt come back til a month later (Now). now it wont go away.
I went to advance auto and had them use their OBD2 reader for a trouble code and i got p0300, p0301, p0303, p0304. No other codes present.
I am not feeling anything bad, and from what I am told, a misfire feels like a hard shift. This is of course after getting the plugs and wires changes as well as an oil change. Standard preventative maintenance.
The mechanic used OEM parts got from local parts shop. i think the OEM plugs are the copper ones. I would have preferred iridium as they arent that much more expensive but I don't want to pay for another plug change.
The only symptoms I can think of, is that according to google, I should get around 380 miles to a full tank (11.9 capacity, 32 mpg city). I am only getting 280 from full tank to gas light.
I have also gone through a lot of oil. I checked the dipstick and it was below the low line, so i bought a quart of high mileage oil (same exact brand and type of oil that i gave to the mechanic to use) and it went to just above the full line. This was at around 1500 miles after oil change.
After visiting multiple sites about misfires, i found a few things that caught my attention. One is a site called auto service professional, which talks about the OCV for the MC accent. A lot of sites also recommend gaping the plugs at .035.

Pontiac - Grandam :: 2001 - Random Starting / Fuel Pump Will Not Kick In
I have a 01 GrandAM 3.4. I have a reoccurring problem with this car. The car will randomly not start, and die while driving. Some days I can drive the car with no problems, and some days it will only have starting problems. These problems are very random. When the car doesn't start it will crank and turn over however the fuel pump will not kick in. You can turn the key on and off several times, and it will fire up. This DOES NOT seem to be a problem with the passlock theft system. The security light has never came on, and you do not have to wait any amount of time for the car to start, you only have to flip the key back and forth several times. The car after running will occasionally die, after the car dies it will usually start back up on the first try. I am very puzzled by this problem not sure if it is the ignition switch, fuel pump, or something in between.
