Ford :: 1994 - Fuel Injectors Making Loud Noise
I recently bought a 94 Ford Ranger XL 2.3L. This is a Mazda engine built for Ford. There was a slight ticking noise from the engine. Two months later it has became worse and louder. I bought a mechanic stethoscope and found the noise was coming from two or more of the fuel injectors. New plugs and wires, fuel filter, air filter was done when I bought it. Cleaner has been added to the gas a few times now. I am about to replace the belts and hoses, Bosch platinum plugs and fuel injector O-Rings. I just don't know if it will be enough.

I have a 1988 f-250 with a 460 motor. I have fuel and I have fire. And the truck starts with I prime it. I tried looking for the crank sensor but can't find it. I looked behind the balancer and I didn't feel any wires or anything. I checked on the sides of the motor nothing. It has a new coil pack and ignition mod. Fuel pump and starter. What else can it be?

I have an 86 F150 that is idling rough. It used to cut out on me until I replaced the fuel pressure regulator. I have read in other posts that the problem for my rough idle could be leaking injectors. When I replaced the regulator I found a bad injector. My question is that if I check my fuel pressure, with the new regulator, would the only way I would lose pressure be that my injectors are leaking?

1988 F250 351 5.8
I've worked for months on this truck and I now have it in the shop. The truck shows a 41 code and has a lean miss at idle that get worse during acceleration and cruise. The injectors were refurbished 6 months ago and the ECM was replaced 3 months ago. All sensors are new and within specs. Fuel pressure is good and there are no vacuum leaks.
The mechanic has verified that the condition is not electrical related. The O2 sensor will react if carb cleaner is sprayed into the throttle but other wise shows constantly lean. He's now checking all pins at the computer for any off condition. He is suspicious of the refurbished injectors. I'm wondering if the computer somehow went out again. Which way to go or what/how next to test?

I have a 1994 Ford 460 motorhome with a intank fuel pump that quits when it gets hot. so I was thing of butting a heavy duty in line pump on and just pull it through the old pump can this be done safely. Or is it best to drop the tank and just put a new fuel pump in.

I'm looking at replacing the fuel lines in my 94 F150 and the big question is what to do with hooking up to the fuel lines coming out of the fuel pump hat and the fuel rails? Ford uses a specialized pressure fitting on it's custom fuel lines. I think there may be some third party fittings that would replace these, but I'm not sure. I could use a standard hose and cable clamps, but I just don't trust that kind of connection for a fuel line.

I have a 1989 GMC suburban V8 350 5.7l that will not start. I have replace the following fuel pump and sending unit, fuel pump relay, ECM computer brand new, new fuel filter. When I go to start it the fuel injectors dont spray fuel into the combustion chambers verified fuel injectors still work by bypassing them and they spray fuel. Fuse's are not blown. I have been told the oil pressure switch might be bad but I'm at my end of sanity on this.
Additional Details : Tried spraying fuel into the throttle body and still no fire, ignition module and ignition coil where replaced 15,000miles ago.
Prius (2004-09) :: Vehicle Low On Fuel Causing ECU To Shut Down Fuel Injectors
I took my 2008 Prius to Jiffy Lube to have oil changed. When driving away, I made it about one block and all warning lights came on: Master Warning, Hybrid System Warning, Brake System Warning, Malfunction, etc. I pulled the car over and stopped. I started the car again, lights still there - drove 2 blocks back to Jiffy Lube and lost momentum about one block away, with pedal to floor, I could drive about 5 miles an hour into the bay. They looked at it for about 30 minutes and claimed I had bird seed that dropped under the air filter.... I said "goodbye" called AAA and had it towed to my dealer. They said it was because air had entered the system due to my being low on fuel. I have never heard of being low on fuel and it causing the car to shut down nor did I ever get a warning of low gas, still on one bar. Each time I restarted the car at Jiffy Lube, it started fine, drove forward or backward, then lost momentum again. Still no warning of being out of gas. The ticket from the dealer states:
"Vehicle low on fuel causing ECU to shut down fuel injectors when engine started to misfire. Found codes P0A0F, P3190 in system. Added 5 gallons of fuel and reset ECU."
Ford Fuel System :: Location Of Check Valve That Maintains Fuel Pressure On The System?
I have a '99 E-350 6.8L. Where is the check valve that maintains fuel pressure on the system?
I have been experiencing a starting issue when the engine is hot. Cold starts are usually fine. I've replaced the in-tank fuel pump (pump only, not the assembly) to no avail. I was out of town and didn't have access to a fuel pressure gauge when the problem started so I couldn't say what I had prior to replacing the pump. But now, with a new pump, when I check pressure, I get about 40 psi when I first cycle the key on, but it drops right back to zero as soon as the pump shuts off. If I cycle the key on a few times, sometimes I can get it to hold pressure at about 32 psi, and it starts fine. When I shut if off, it goes back to zero psi, sometimes gradually, like a bleed down, and sometimes immediately.
My conclusion from this was that the check valve was bad. I was told it was part of the in tank fuel pump assembly. Since I didn't replace the entire assembly, this made sense. So I just dropped the tank back down, but I don't see anything as part of the pump assembly that serves as a check valve. There is a rubber nipple on the end of the return line, but I don't see how that can hold any significant pressure.
So, before I go out and spend another couple hundred bucks on the complete fuel pump assembly, which apparently can't be purchased without the actual pump, I thought I'd ask. Where is the check valve that holds the pressure in the fuel system?
BTW, I also have replaced the fuel rail pressure regulator, but it made no difference (I went there first since that was much easier than dropping the fuel tank a second time).
