there is a fuse for the fuel pump plus a relay on the fire wall.

Ignition Switch - REMOVAL & INSTALLATION
(see Figure 1)

1. Disconnect the negative battery cable.
2. Remove the lower column trim panel, then remove the steering column-to-instrument panel fasteners and carefully lower the column for access to the switch.
3. Place the ignition switch in the OFF-LOCK position.
   

If the lock cylinder was removed on vehicles through 1991, the actuating rod should be pulled up until it stops, then moved down one detent; the switch is now in the Lock position.

Fig. 1: Adjusting the ignition switch

1. Remove the ignition switch-to-steering column retainers, then remove the assembly.
   

To install:

1. Before installing the ignition switch, place it in the OFF-LOCK position, then make sure that the lock cylinder and actuating rod are in the Locked position (1st detent from the top or 1st detent to the right of far left detent travel).

Most replacement switches are pinned in the OFF-LOCK position for installation purposes. If so, the pin MUST be removed after installation or damage may occur.

1. Install the activating rod into the ignition switch and assemble the switch onto the steering column. Once the switch is properly positioned, tighten the ignition switch-to-steering column retainers to 35 inch lbs. (4.0 Nm).
   

When installing the ignition switch, use only the specified screws since over length screws could impair the collapsibility of the column.

1. Raise the column into position and secure, then install any necessary trim plates.
2. Make sure the ignition is OFF , then connect the negative battery cable.

Ignition Lock Cylinder - REMOVAL & INSTALLATION
(see Figure 1)

1. Disconnect the negative battery cable.
2. Matchmark and remove the steering wheel.
3. Remove the turn signal switch from the column and allow it to hang from the wires (leaving them connected). For details, please refer to the procedure located earlier in this section.
4. For vehicles through 1991, place the lock cylinder in the Run position.
5. For 1992-93 vehicles, remove the buzzer switch assembly.
   

Fig. 1: Ignition cylinder replacement

1. Carefully remove the lock cylinder screw and the lock cylinder. If possible, use a magnetic tipped screwdriver on the screw in order to help prevent the possibility of dropping it.

CAUTION If the screw is dropped upon removal, it could fall into the steering column, requiring complete disassembly in order to retrieve the screw and prevent damage.
To install:

1. Align and install the lock cylinder set. On vehicles through 1991 it will be necessary to rotate the switch clockwise to align the cylinder key with the keyway in the housing.
2. Push the lock cylinder all the way in, then carefully install the retaining screw. Tighten the screw to 22 inch lbs. (2.5 Nm) on tilt columns or to 40 inch lbs. (4.5 Nm) on standard non-tilt columns.
3. If necessary, install the buzzer switch assembly.
4. Reposition and secure the turn signal switch assembly
5. Align and install the steering wheel.
6. Make sure the ignition is OFF , then connect the negative battery cable.

Keep us updated about your advance.

it could be your ignition module if there is no spark( module located inside distributor cap , under rotor)

Best bet is go to your local major chain auto parts store (Pep Boys, Advance, Auto Zone, O'Reilly's, etc. and purchase a vehicle specific repair manual. It will contain all of the info you have inquired about and shouldn't cost much over $20

If you don't want to buy one, go to your local library and check out a vehicle specific manual.

Hello Maedtm.

Fuse #3 in the instrument panel fuse block is marked T/L CTSY.

Recommend you loosen the fuel line at the carburetor to see if there is pressure there. If yes, take the float bowl cover off to see if the bowl is filling. If the bowl is not filling, there is a clog between the line and the float needle--use a wire to clear out the clog. If the bowl is filling, remove the carburetor and rebuild it or replace with a rebuilt one. Rebuilding a carburetor is not hard, but in the case of a clogged carb, you need to clear all the passages well. Please let me know if you have questions and thanks for using FixYa.

the code port is just under dash driver side. sounds like air flow sensor .

WELDING IS OK! OR TRY LOCAL SALVAGE YARDS, TRY LMC TRUCK PARTS ON GOGGLE. THANKS MOTOR62500

Good Lord! The FILTER should never be fuel soaked. I would have it given a full tune up, have the carb tuned, and then, for heaven's sake, check the distributor timing. That, and less importantly (I doubt it's the valves if it runs) the valve/cam timing. But mostly check that distributor!

did you change the rubber lines also? they will cause one side to lock up. the insides of the hoses break and do that.

it drop a vavle or broke piston rod you have a blown motor . replace it or you migth can save some of this one to rebuild.

there are 3 lines on the transfer. one is a vent that t's to the vent of the transmission. one goes to the vacuum bottle. and the other goes to the actuating bladder on the right fender by battery. the switch is actuated when you select a 4wd position and then the vacuum actuates the front axle. very simple setup.

Either a black womens **** or the bomb i made the other day

Check fuel pressure prior to starting truck when cold. If there is no pressure in the system what is happening is that your check valve in the fuel pump has gone bad and allowing fuel pressure to relieve itself back into the tank. This causes a large air bubble in the fuel line that can take quite sometime to purge before it starts when fuel reaches the throttle body, which explains your long crank hard start.

If you have no means to check pressure you can also remove the air cleaner and look into the top of the throttle body while an assistant attempts to start the truck when cold. You should see fuel instantly if you do not your pump is failing to hold system pressure.

If your system is failing to hold pressure between starts the remedy is to replace the fuel pump.

in order to get the oil pan off of a 4 w/d model the front axle assy must be removed first then oil pan removal is straight forward after that. cv axles can be left in just need to take out the 6 bolts on each one drain oil out remove the cable engagement on the bottom wire plug and 4 mounting bolts. rotate assy to remove it. the other way is to remove the engine. take your pick.

the ecm signals the injectors, its controlled by the ignition module, no spark no fuel, check the pruple wire, its the signal
