Many dodge trucks have had problems with the gas caps. Believe it or not if it's not put on correctly in some cases, others I have known had to drill very small pin holes in the cap, and others try an up-grade gas cap and solved this problem.

SOURCE: 1996 Dodge Ram 1500 kept stalling while driving now won't start

First off you can test the fuel pump 2 ways
1.have a assistant turn on the ign to on while you listen for the pump to run at the gas cap (gas cap off).
2.find the valve on the fuel rail looks like a a/c or valve stem,take the cap off and press the needle and if fuel comes out then it's not the fuel pump.

But from a lot of EXPERIANCE on dodge engines the stalling and restarting issue is ignition related i.e crank or cam sensor which will throw a diagnostic code of engine misfire xxx cylinders.

So If its one of those sensors then you will not have any spark,and staring fluids will not fire the engine.
As for the headlights flickering they get there power through a relay straight from the battery,so I would look at the relays under the hood and find the one for the headlights and swap it out with the horn relay as most of the relays will have the same numbers.

The crank sensor is about 70.00 and the cam sensor is about 50.
depending on where you get them (dealer or aftermarket)
the cam sensor is the round plastic thing under the dist cap,and the crank sensor is on the pass side under the head into the top of the transmission bell housing and it's a 2hr job to change because of it's location is really hard to get to.
Hint -take the breather off and place a rag over the intake and a board from the radiator core support to the intake to lay on,it has 2 10mm bolts and the wiring harness unplugs from underneath.

Check the spark plug wiring . There are several places where the wires cross each other. These wire cross points MUST be at right angles to each other. Or you will have a misfiring problem.

My digital gas gage reads full all the time I have to go by my miles and sometimes that don't work and I run out of gas..how do I fix my problem


This is a common problem and to correct this problem will require the replacement of the fuel sending unit. The fuel sending unit is inside the fuel tank and has the fuel pump mounted in it. This requires the removal of the gas tank and then the fuel sending unit can be removed from the tank.

REMOVAL AND INSTALLATION Fig. 1: Fuel pump unit 8470h037.gif
  1. Disconnect the negative battery cable.
  2. Relieve fuel system pressure.
  3. Remove fuel filler cap to release fuel tank vapors. Leave cap off until repairs are completed. Gasoline fuel vapors are extremely flammable. Ensure that fuel is stored in a container that can be properly sealed. Never store fuel in an open container. Store container in a safe place away from heat.
  4. Remove fuel tank by performing the following:
    1. Step 1: Drain fuel from the tank into an approved container for storage.
    2. Step 2: Raise and safely support the vehicle.
    3. Step 3: Remove rear stabilizer bar at links, pivot bar downward.
    4. Step 4: Remove hoses and pipes from tank unit.
    5. Step 5: Remove hoses at tank from filler and vent pipe.
    6. Step 6: Disconnect tank unit harness from rear body harness.
    7. Step 7: Support fuel tank and disconnect 2 fuel tank retaining straps.
    8. Step 8: Remove tank from vehicle.
  5. Remove sending unit, gasket and pump assembly by turning cam lock ring counterclockwise. Lift assembly from fuel tank and remove fuel pump from fuel tank sending unit.
  6. Pull fuel pump up into attaching hose while pulling outward away from bottom support. Take care to prevent damage to rubber insulator and strainer during removal. After pump assembly is clear of bottom support, pull pump assembly out of rubber connector for removal. To install:
  7. Push fuel pump assembly into attaching hose.
  8. Install fuel tank sending unit and pump assembly into tank assembly. Use new O-ring seal during reassembly.
  9. Install cam lock over assembly and lock by turning clockwise.
  10. Support tank and position in vehicle. Install tank straps and secure with retaining bolts. Tighten to 25 ft. lbs. (33 Nm).
  11. Connect tank unit harness to body harness.
  12. Connect hoses to filler and vent pipes. Tighten clamps.
  13. Connect hoses and pipes to tank unit.
  14. Connect rear stabilizer bar to links. Tighten bolts to 42 ft. lbs. (58 Nm).
  15. Lower vehicle.
  16. Refill tank and install filler cap.

I cant get the cap off of my gas tank to take the fuel pump out, how do I get the fuel pump out?


Relieve the fuel pressure at the pump switch located in the passenger compartment under the carpet of the transmission hump on the passenger side. Remove the fuel tank. Turn the lock ring counterclockwise until it's loose and remove the lock ring. Pull the fuel pump/sending unit from the tank being careful not to bend the arm for the sending unit float. Discard the old lock ring seal. Installation is reverse of removal with the following additions: (a)Apply a coat of heavy grease to the new lock ring seal to hold it in place during assembly. Install the seal in the lock ring groove. (b)Install the fuel sender/pump unit into the fuel tank so that the tabs of the unit are positioned into the slots in the fuel tank. Make sure to keep the seal in place during installation until the lock ring has been tightened properly. (c)Hold the fuel sender/pump unit in place, install and tighten the locking ring clockwise until the stop is against the retainer ring tab. - Mazda Pickups Repair Manual

I need to replace the fuel pump in my 1985 Chevy S10 pickup, need all help. What is the procedures?


EXACT PROCEDURE ! Please Rate Me Fairly for this!! Thank you And Good Luck !!


ELECTRIC PUMP

REMOVAL
  1. Before servicing the fuel pump the fuel system pressure must be relieved. See: Fuel Pressure Release
  2. Disconnect the negative battery cable.
  3. Raise the car on a hoist.
  4. Remove the fuel tank. See Fuel Tank / Service and Repair.
  5. Remove the fuel tank sending unit and pump assembly by turning the cam lock ring counterclockwise. Lift assembly from the fuel tank.
  6. Pull the fuel pump up into the attaching hose while pulling outward away from the bottom support. Take care to prevent damage to the rubber insulator and strainer during removal. After the pump assembly is clear of the bottom support, pull the pump assembly out of the rubber connector for removal. NOTE: Inspect the fuel pump attaching hose for any signs of deterioration. Also check the rubber sound insulator at the bottom of the pump. Replace damaged or deteriorated parts.
INSTALLATION
  1. Push the fuel pump assembly into the attaching hose.
  2. Position the fuel tank sending unit and pump assembly into the fuel tank. Use a new "O" ring seal. NOTE: Care should be taken not to fold over or twist the strainer when installing the sending unit as this will restrict the flow of fuel. Also, verify that the strainer does not block the full travel of the float arm.
  3. Install cam lock over the assembly and lock by turning clockwise.
  4. Reinstall fuel tank.
MECHANICAL PUMP

REMOVAL and INSTALLATION

NOTE: To ease pump installation, rotate the camshaft so the camshaft eccentric is out of the way of the fuel pump rocker arm.

  1. Disconnect fuel lines from fuel pump.
  2. Remove fuel pump mounting bolts and the fuel pump.
  3. Remove all gasket material from the pump and block gasket surfaces. Apply sealer to both sides of new gasket.
  4. Position gasket on pump flange and hold pump in position against its mounting surface. Make sure rocker arm is riding on camshaft eccentric.
  5. Press pump tight against its mounting. Install retaining screws and tighten them alternately.
  6. Connect fuel lines. Then operate engine and check for leaks.
