My 2005 town and country it won't started I replaced fuel pump coil pack I do have spark and injectors pulses but it won't star only if I sprayed fuel on the intake hose


Check the fuel pump fuse and relay first( just swap the relay in the panel). Is the security light staying on? Do you know how to use a volt /ohm meter?

1993 ford ranger.4.0 what will cause the fuel to bleed back when switch is off?after about 10 min. i have to give it a shot of gas in throttle body to start it.just replaced fuel pump,filter & pressure...


do you have injector pulse durng initial cranking? you may have a bad cam shaft position sensor that "comes to life" when rpms are up. or an injector has a bad spray nozzle allowing fuel to flow into its cylinder,pulling the spark plugs and checking for any that may be "wet" or smell ''rich'' will help pin-point your problem.

1998 buick park avenue ultra changed fuel pump fuses good relay good pump not working does pcm control this function if so is there a test i can perform to check


PCM stands for Pulse Code Modulation. Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form for fuel injection computers. A PCM stream is a digital representation of an analog signal, in which the magnitude of the analog signal is sampled regularly at uniform intervals, with each sample being quantized to the nearest value within a range of digital steps. So no, Pulse Code Modulation does not control the fuel pump. The Fuel Injection Computer does control the fuel pump via a relay. Bad connection between the fuel pump relay and the in-tank fuel pump, or a bad fuel pump.

I changed the fuel pump on a 1997 Monte Carlo 3.4 motor and now I have no fuel pressure. The pump motors turns on but it doesn't pump any gas. Do I have to bleed the fuel system? and how do I do...


Disconnect fuel filter near tank and turn on, if you still hear the pump pulse and nothing comes out, a good chance that little 3" hose between pump and pick-up tube came off. Also, make sure it wasn't ran dry. There is no bleeding. Check the fuel rail schrader valve if you have fuel at the fuel filter. Good luck, will check on you later.......

1990 dodge dakota 2.3 v-6 auto-----just put new fuel pump and filter, and everything back to normal but still not getting fuel to tb inj.? cranks over but still nothing.---i can pour gas directly in and...


2.3 V-6? You should be a 2.5 V-6 whether you have a TBI (throttle body injector) or sequencial, If there is no injector pulse then move your inspection to the distributor, there you will see a distributor pick up, this controls spark and fuel, and yes the rule is if there is no spark then there is no fuel but you case is special you have spark and no fuel pulse,you will need to inspect this for corrosion as it can give spark and no fuel injector pulse,that is one area of no injector pulse, Then inspect the MAP sensor (your a spped density), the most common complaint for a map sensor is it start then dies. inspect this sensor its mounted on the firewall make sure the vacuum hose is connected, and that it is plugged in.

How to replace a fuel pump on a1997 Chev Venture



  1. Properly relieve the fuel system pressure and install a pressure test gauge according to the tool manufacturers instructions.
  2. Turn the ignition switch to the ON position for 3 seconds, then turn to the OFF position for 5 seconds. Repeat this procedure two or three times to pressurize the system. Again turn the switch to the ON position.
    1. On TBI equipped vehicles, the gauge should read a static pressure of between 9 and 13 psi (62-89kPa)
    2. On SFI equipped vehicles, the gauge should read a static pressure of between 41 and 47 psi (248-325kPa)
    3. If not, check for a clogged fuel filter, a kinked fuel line, or an inoperative fuel pump.
  3. On TBI equipped vehicles, the fuel pressure will drop after the fuel pump stops running due to a controlled bleed in the fuel system. Use of the fuel pressure gauge will determine if the fuel system pressure is enough for the engine to start and run.
  4. No fuel spray from the injector indicates a faulty fuel or ignition system or no PCM control of the injector.
  5. This test will determine if the ignition control module is not generating the reference pulse or if the wiring or PCM are at fault. By touching and removing a test light to B+ on CKT 430 (purple/white wire from the ignition system), a reference pulse should be generated. If the injector test light blinks, the PCM and wiring are OK.







If the pump tests bad...
Disconnect the negative battery cable.
  1. Relieve the fuel system pressure.
  2. Block the front wheels and raise and support the rear of the vehicle safely. Make sure the rear is high enough to accommodate the removal of the fuel cell.
  3. Loosen the fuel filler neck connecting tube clamp at the tank.
  4. Wrap a shop towel around the fuel filter neck connecting tube and slowly remove the fuel filler neck connecting tube from the fuel tank.
  5. Position a siphon hose into the fuel tank through the fuel filler opening. Place the other end into an approved container with enough capacity to hold the fuel in the tank. Siphon the fuel.
  6. Raise the vehicle to gain access to the fuel tank. Make sure the vehicle is safely supported.






  1. Disconnect the tail pipe hanger attaching bolt.
  2. Remove the muffler hanger attaching bolts and remove the muffler hanger.
  3. Loosen the converter hanger attaching nuts.
  4. Remove the two heat shield attaching screws and note the position for reassembly.
  5. Support the exhaust and move the heat shield to gain the access to the right side of the fuel tank retaining strap attaching bolts.
  6. Remove the in-line fuel filter body clips.
If the nylon fuel feed or return lines becomes kinked, and cannot be straightened, they must be replaced. Do not attempt to repair sections of the nylon fuel lines.
  1. Disconnect the quick-connect fitting at the fuel filter, and return line fitting.
  2. Disconnect the fuel tank electrical connector.
  3. Disconnect the vapor hose at the fuel tank.
  4. Disconnect the vent hose at the fuel tank.




With the aid of an assistant, support the fuel tank, remove the left and right tank retaining strap attaching bolts, and remove the tank.
  1. As necessary, remove the fuel sending unit (which includes the fuel pump), as outlined, in this section.
  2. Then you can change the pump:
  3. Remove the fuel sender assembly.
  4. Disassemble the fuel pump strainer and the fuel pump: Note the position of the strainer in relation to the pump.
  5. See Figure 3


    Fig. 3: Remove the fuel tank locking ring with a non-sparking (brass) punch.


    1. Support the fuel pump in one hand, and grab the strainer in the other hand.
      1. Rotate strainer in one direction and pull off pump. Discard strainer.





      1. Remove deflector.
    1. Disconnect the fuel pump electrical connector.
    2. Loosen the two connecting clamps, if equipped.
    3. Place the fuel sender assembly upside down on the work bench.
      1. Pull the fuel pump downward to remove it from the mounting bracket, then tilt the pump outward and remove it from the connecting hose or the fuel pulse dampener.
    4. It is recommended to replace the hose and clamps, if equipped.
    To install:
    1. Push the fuel pump assembly into the attaching hose. Attach the pump electrical wires and fasten the hose clamps to the attaching hose and around the pump body, where equipped.
    2. Place the fuel tank sender and pump assembly into the fuel tank. Use a new O-ring seal during assembly.
    3. Then put the tank back in:
      1. If the fuel tank is replaced, transfer the fuel feed and return lines from the mounting clips, the vapor hose from the mounting clips and the vent hose from the vent hose fitting.
      2. Check the fuel filler neck for cracks and holes and replace as necessary.
      3. Install the fuel sending unit.
      4. With the aid of an assistant, position and support the fuel tank and install the left and right tank retaining strap attaching bolts and tighten to 18 ft. lbs.
      5. Connect the vent and vapor hoses.
      6. Connect the fuel sending unit electrical connector.
      7. Connect the quick-connect fittings as outlined.

How to change the fuel pump on a 1996 Pontiac Transport


For 1996 Pontiac Truck Trans Sport 3.4L SFI 6cyl check this procedure for Fuel Pump... there are two different electric fuel pumps used:
- A medium pressure twin turbine pump for vehicles equipped with Throttle Body Injection (TBI). - A high pressure roller vane pump for vehicles equipped with Sequential Fuel Injection (SFI).
(see Figure 1)


d7f6f20.jpg


Fig. 1: View of the fuel pump assembly and related components
The fuel pump is mounted to the fuel sender assembly inside the fuel tank. The fuel is pumped to the engine at a specified flow and pressure by the fuel pump. Excess fuel is returned to the fuel tank by the return pipe. The fuel pump delivers a constant flow of fuel to the engine even during low fuel conditions and aggressive vehicle maneuvers.

CAUTION When working on or near the fuel tank, be sure to observe the information molded on the bottom of the tank.
Removal & Installation
  1. Disconnect the negative battery cable.
  2. Properly relieve the fuel system pressure.
(see Figure 2)

What would cause no fuel pressure and no injector pulse in a 1995 Dodge interpid with a 3.3 L


if your checking the injetctor pulse with a noid light ? then the reason for no pulse is the ECM! also would affect the fuel pump driver circuit if your just guessing theres no pulse/ ? then check the fuel pump at the connectors to insure theres voltage and the pump runs'

No start


if it runs on starting fluid its a fuel problem.. check fuel pressure even if its a couple of pounds off, the vehicle will not run. but using starting fluid may give you the extra poundage you need to make it run . also check vacuum hose at pressure regulator on fuel rail
