SOURCE: bad fuel pump on 1982 volvo 244 diesel

It could be a blocked pickup in the tank but is more likely a dead fuel pump. Pickuo is located in top of tank and is accesed through the boot(trunk) floor.
Fuel pump is under the right hand rear corner of the car and is mounted on an insulated plate with the accumulator.

SOURCE: Hi - the Toyota Starlet

You are asking for a LOT!!!
Fuel flow or glow plugs or injectors is not what I would call "nailed down". That is an extremely broad spectrum! You only have it nailed down to 3 separate systems that have probably 100 or more parts each. We won't even get into the fact that there are sub-sytems to these systems that can cause starting problems.

Most of what you are asking for is copyrighted material and cannot be posted here anyway.
The best recommendation I can give you (if you really want to try to fix this yourself) is to subscribe to the service information for your vehicle at AllData DIY for a small fee.

Once you are in there, you can go to "Powertrain Management" and look under "Diagnosis By Symptom" and look for "Hard or No Start" There will then be step-by step diagnostic routines with diagrams to guide you through the process.

SOURCE: un connected vacum line,apprx.6''

Hi Michael: here you have two diagrams...



DTC P0440 code indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
A code P0440 could mean one or more of the following has happened:

  • The gas cap is not installed or working properly
  • The purge solenoid has failed
  • The canister is plugged and not working properly
Additional details could find in this links Fault Codes on Cars & Trucks or other diagrams in Cars & Trucks Vacuum Diagram.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Fuel line diagram for 2004 ford explorer sport trac

It runs from the tank to the frame(drivers side) up to the engine. I don't and you should splice fuel lines. I replace all of it. Plastic or metal. If the leak is coming around the sides of the tank, this could be the fuel sending unit.

Have a 1986 golf diesel it ran out of diesel and I

Are you certain that you put diesel fuel in the car? Had to ask that question. How long did the car sit before you refueled? If it sat for a while and if the temperatures and humidity were enough to produce a build up of water vapor, that might keep the injectors from sending "dry" fuel to the cylinders.

Just running out of fuel won't harm the glow plugs (hence poor starting) and won't require need for a new battery unless the current battery was failing even before draining the tank.

Does my 1974 dodge dart with a 318 motor have a fuel return line on it fuel sending unit?

Hey Jim,I see that it is showing 2 types at auto part stores.You can see the return line on the one with it,the way to find out is when you change you will see.Not good to buy in advance,may have to order.
  1. Usually a pump with a return will have a separate connection to go from the pump back to the cell. If yours has that connection ,I would put the return line back to the cell on it.
    A return line is nothing more than excess fuel being returned to the cell.

Ran out of diesel now vehicle won't start

This is not unusual on a diesel. What happens is there is air in the system. If this vehicle has an electric fuel pump loosen line where fuel enters injection pump then turn ignition key to the on position and watch for fuel to appear and then quickly tighten line before turning off key. Then try to start. If does not have electric fuel pump will need a second person. One will loosen line and watch while other cranks vehicle until you get fuel and tighten line before the other person releases ignition switch unless vehicle starts first. If that doesn't do the job do this where line hooks onto each injector. Probably will not have to do this to all injectors but could run rough until all the air gets out of everything. I have farmed with diesel tractor for 25 years and dad I drove the gm vehicles with the 5.7. You normally don't start a diesel without bleeding the air out of the lines although some will self bleed most won't. Hope this does the trick.

How much to replace a fuel pump in 97 buick lesabre

The fuel pump is inside the fuel tank. To replace it you must remove the fuel lines, fill and vent hoses, and the electrical connector at the fuel tank. Then the two straps holding the tank in place must be released and the tank will come down. A lock ring holds the sending unit and fuel pump in place and must be removed by sliding it counterclockwise, then the sending unit and pump will come out as an assembly. Often the sending unit lines are too corroded to be reused, or are too corroded to release the fuel lines. In that case I cut the steel lines at the sending unit with side cutters, which allows me to take the lines down and position them where I can pick the rust out from the connector sockets and, eventually unlock the fuel lines. The sending unit must be replaced; and I just order complete assemblies ready to drop into the tank. You'll also want to replace the o-rings on the fuel lines.

2005 Dodge Dakota V8 4.7L, 4X4, engine light on, code P0452 . Where is the fuel pressure sensor located?

  1. The Fuel Level Sending Unit, or Fuel Level Sensor, is located in your gas tank with the Fuel Pump Module. The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The sending unit consists of a float, an arm, and a variable resistor track (card).
  2. The Fuel Pressure Regulator is located within fuel pump module. The fuel pressure regulator controls fuel system pressure. The PCM cannot detect a clogged fuel pump inlet filter, clogged in-line fuel filter, or a pinched fuel supply or return line. However, these could result in a rich or lean condition causing the PCM to store an oxygen sensor or fuel system diagnostic trouble code.
Both of these sensors are connected with the Fuel Pump Module. Here is a diagram:

I'm looking for a diagram for my 1997 GMC Jimmy. The gas tank is leaking and I want to see all the parts that I might have to order.

This is hard to say with out removing the tank, you will need a tank and sometimes the sending unit and pump while tank is down the only other thing would be the fuel lines, if the lines are rusted and dont come loose then you will neeed to make new ones, heres a couple of diagrams to help you, take note there are two style tanks depending on if you have a 2 door or 4 door, one mounts in the rear and the other on the side, i also belive you have plastic fuel lines and shouldnt have a problem with them, while the tank is out the pump asm, which comes complete with sending unit and pump should be replaced, hope this is helpful, good luck.johnjohn2_1.jpgjohnjohn2_2.jpgjohnjohn2_3.jpgjohnjohn2_4.jpg

Leak on diesel fuel tank after filling it, 1994 Renault Traffic

Well because of the age I think you need a new fuel tank. It could be a rotted fuel line, sending unit, or hose . You will still need to drop the tank to find out what you need. NOTE, use up most of the fuel before dropping it. you dont want it to fall freely or damage will come to electrical components.
