Golf IV R32 :: Fuel Pressure Drops In Seconds
This problem just cost me a new starter and flywheel, cuz after cranking my engine so many times the starter mess up the flywheel teths, anyways, i install a fuel gauge and i find out that my pressure drops in seconds, like i turn the key on (pos ii) and but the time i get out the car to the engine bay to look at the gauge, the pressure is almost ZERO
When I open the door the fuel pump primes and built pressure, when i turn the key i heard the pump primes too, but why does the pressure drops so fast?
I have an aeromotive fpr, and a bosch in line pump, turbo set up and 550 cc injectors( brand new )...
Ford - Explorer :: 2003 - Fuel Pump Pressure Drops?
I have an 03 Explorer that had a starting issue. Long story short, it had no fuel pressure. So after testing the relay, I switched out the pump with an Airtex unit . All seemed fine...for a while.
Became hard to start again, checked Schrader valve with the key on, and not running, no pressure. Strange though, it would run.
So got the fuel pressure gauge on it. Turn the key and pressure will go to about 5-10psi and then drop to zero. Turn key off and on again, up to 5-10psi, then drop to zero. Turn the key to start and pressure goes up to 10psi, then starts, then goes to 30 while running and you can drive it around. Shut off motor and pressure goes down to zero.how the sending unit is supposed to hold fuel pressure and not release it? Is there some kind of check valve in the sending unit assembly that can be cleaned or does it need a whole sending unit with another pump? I already spent the $100 for the pump, and it is working if you can drive it!
Ford - Explorer :: 1998 - Temp Gauge Shooting To High In Just Seconds Then Drops Back To Normal
For reasons I can't figure, the Temp gauge on the wife's Explorer is shooting from normal to high in just seconds. Then, it drops back to normal. When I looked at it this afternoon, I noted 2 things.
1) There was no sign of a coolant leak or overheating.
2) There wasn't ANY coolant in the tank!!!!!!!
The truck has evidently been running fine while this is going on.
Ford F-150 (2004-2008) :: Low Oil Pressure / Gauges Drops / Then Stalling
2004 Lariat. Ford F150, 5.4 Triton. Whenever I slow down, stop, or turn my truck will read low oil pressure, then all my gauges drops and it stalls out. I've taken it to my mechanic twice now. And twice he's replaced two sensors. Today I took it to Wal-Mart for an oil change and they said its probably why my check engine light is on code, T19. I've had that light on for 4 years now and this stalling out problem starts 3 months ago. So far its had regular oil changes, new air filter, two new sensors and im scraping money to throw at it. Hitting snow banks, other vehicles, and tree's... need to find the real problem before I go broke or worst kill someone in an accident.

I have a 2003 4.6l f150 164000 miles. While back oil pressure dropped to 0. Then chattering. Then up then down. I changed the oil and filter, then flushed the motor, then changed the oil and filter again. 1500 miles, no problems, no chatter. Then all of a sudden it happens again. Oil level good and clean. Oil pump?Pick up tube?

I have an 01 F150 Lariat Supercrew 4x4 with the 5.4 Triton. The truck has 222,000 miles on it. Recently, I have noticed that when I am stopped at a stop light/stop sign while in gear, the oil pressure gauge drops to zero and the light comes on. As soon as I let off the brake and give it gas, it pops back up to normal. While driving, the needle never moves and stays consistent until I stop again, and back down to zero it goes.
If I put the truck in Park, the pressure goes back to normal. Same with neutral. It seems it is hit or miss and does not do this all the time, but I just wanted to see what your thoughts are. After doing some research I am leaning towards an oil pressure sensor/sending unit.... The truck runs perfectly fine, I just want to make sure it is not something more serious.
Ford - Explorer :: 2002 - Oil Pressure Occasionally Go From Normal To No Pressure Immediately
I have a 2002 ford explorer with 70000 miles on it. The problem is that the oil pressure occasionally go from normal to no pressure immediately. Then within a minute it pops right back to normal. It has happened when I first crank up and sometimes just going down the interstate at a normal speed. My fear is that the oil pressure is really gone and there is a pump problem but with it either working or not I fear it could be a sensor problem.

I've got a '98 F150.throwing codd 402, excessive flow EGR, also the oil pressure drops to absolute zero only when gear shifts but comes right back up. No knocking or other distress sounds in engine. I know I'm in need of an oil change. I already searched a bit and decided to swap out the DPFE sensor which I did purchase from the dealership. No code as of yet but what could that pressure drop be? Could a simple il change and filter fix that?

177,000 miles, fuel pump was replaced just before I purchased it a few weeks ago. Truck has been running like new until today when it started doing this completely out of the blue. If you watch the video, the sound is not off, the tach is moving independently of the sound of the actual revs. Occasionally when doing this, the fuel gauge drops to zero. Thinking this is an electrical issue somewhere.

1993 accord LX- Thought I had the problem solved by taking the 6 small port plugs out of the emissions system and cleaning up all the buildup plus opening the ports back up that were plugged.
When I put a vacuum gauge on the black rubber hose going from the control box to the EGR valve there is an initial buildup of vacuum upon acceleration but within seconds it drops off to zero. I switched control boxes and used one my brother had from his 91 accord he parted out and still had the same result.
Ford Super Duty (1999-2016) :: F250 V10 Oil Pressure Drops At Idle?
I have a 2001 Ford F250 V10 with about 70,000 miles on it and now the gauge indicates low pressure when my warmed up truck idles around 1000 RPM.
I went off road the other day into some mud and since then I have had my oil pressure gauge reporting low at idle and normal when moving.
I was a quart and 1/2 low on oil which I filled and the next day I changed the oil. I then had taken it Ford shop who replaced the oil sensor and said all fixed. It wasn't and I took it back in ... now the mechanic indicated it is probably the crankshaft bearing based on his experience and I should replace the engine.
This seems drastic? Wouldnt' the next step to go check/replace the oil pump?
Ford Excursion :: 2000 - Oil Light On / Pressure Drops - Motor Won't Even Turn / Just Clicks
2000 Ex 5.4 v8
Had 2 coils go bad last week. Got them replaced. Today I am on the turnpike doing 70 and my oil light comes on and oil pressure drops all the way. No engine noises and temp is OK so I coast to the next exit. Get off and go to the gas station in the corner. Turn the truck off...
Wait a few minutes, when I go turn it back on it wont start. The motor wont even turn. It just clicks.
I notice smoke coming from the wire that goes from the starter relay to the starter so my brother comes and gets me and we go to the nearest auto part store and buy a new relay.
Replace it and try to start it, same thing. Just clicks and smoke. My brother gets under the truck and taps the starter as I try to start it, no go. I am fearing the engine locked up. But no engine noises, clicks or clacks or anything. Battery is fine as well. Any thoughts on what else I can try?
Ford Super Duty (1999-2016) :: 2005 F250 V8 - Oil Pressure Drops When Braking
I have an 05 F250 Super Duty 6.0 V8 Turbo Diesel. This is my first diesel so don't know my way around it too much yet. I just don't know what could cause this problem. It sounds like a faulty sensor to me. But no engine light has come on. My oil pressure drops down to in the red zone when I brake while driving, then once I return to driving again it returns to the normal pressure. It's almost as if it has something to do with the tilt of the vehicle.
View 8 RepliesFord Super Duty (1999-2016) :: 2013 V10 - At Idle Oil Pressure Gauge Drops And Red Oil Light Comes On
I have a 2013 F550, v10. At idle, the oil pressure gauge drops and the red oil light comes on. If I hit the gas, the gauge pops back up. I swapped out the oil pressure switch. That didn't fix the problem.
I thought maybe the gauge was faulty, so I bought a 2 inch mechanical oil pressure gauge and hooked that up, leaving the factory gauge disconnected.
I watched the oil pressure start around 50 psi cold, and it slowly fell to 10-15 psi as it warmed up. The truck has 65k miles on it. There is no knocking, no ticking, no loss of performance.
I cannot imagine that at 65k miles, that it would be a worn engine. Right??
Ford Super Duty (1999-2016) :: 2006 F250 V8 - Knocking Noise In Engine And Oil Pressure Drops
While driving today, 2006 Ford F-250 5.4 L V8 138,000 miles , I experienced a problem. Started with the truck acting as if it was running rough, possibly missing. This was approx. 10 Minutes after starting. Checked the dash, no warning indicators and all gauges were normal. Approx. 4 more miles, the oil pressure alarm signals and I see the oil gauge has dropped to zero. I pull over, turn off and check the oil. Oil is clean and at a normal level. I restart the truck and the oil pressure goes back to normal.
Rev the truck up while sitting there and after a few seconds i hear a knocking noise in the engine and oil pressure drops again. Call the tow truck, driver used to be a mechanic . He asks me to start it again and the same thing happens. If you start it and let it idle oil pressure seems to go up to normal with no engine noise. Finally get to the mechanic and he calls me later saying the oil pump and screen may need to be replaced or the engine may need to be replaced.
Nissan - 300zx :: Engine Surge At Highway Speeds For Several Seconds Then Drops Back Down To Normal
my 1990 Nissan 300zx with 136,000 miles often surges at highway speeds for several seconds then drops back down to normal. the surge is usually 1000 rpm. does not happen if not in overdrive, and will not happen unless having been driving for 15 minutes or so. also seems to occur more on hot days (80 degree +) than on cool days. mechanic has looked at this several times but not yet able to determine why.
View 2 RepliesLexus GS 2006-11 :: Pressure Sensor Won't Warn Unless It Drops Below Low Level
I have aftermarket wheels and the tire pressure sensors have been transferred over. Since I went from the stock 17" wheels to 20" wheels, I had to increase the tire pressure from 32 to about 38.
1) I'm assuming that since the pressure is now higher with the 20" wheels, the tire pressure sensor won't warn me unless it drops below a really low level (maybe somewhere around 28 psi). Is there any way I can set a higher threshold so that they come on at around 36 psi?
2) The tire shop that installed the wheels transferred over the sensor, but I'm not sure if they actually work since the warning light has ever came on. Do I need to take the car to the dealership for them to start working again?
Based on the my research, some people are saying that only the dealer can reset the TPS so they can start working again. Others are saying that I can reset it myself, but does this reset actually raise the threshold?
