Question about 1988 Ford F 250

Open Question

Need wiring diagram for 88 ford f 250 tach and voltmeter.

Need wiring diagram for 88 f 250 showing tachometer circuit from inst panel, all the way to distributor and coil. i took the 351w out, out in carburated 460. electronic dist and brainbox are out of 83 f 250. part #on brain is D6AE 12A199. # on dist is C8VF 1213-8orB. the coil i just bought at napa for 83 f 250 indicates no external resistor needed. other coils say on them to use with resistor, this one does not. so i assume this electonic ign syswill not need an added in resistor. so i may need a diagram for the 83 f 250 460 elec ign sys dist and control box.

SOURCE: i need a wiring diagram for an 83 crown victoria starter coil

if you turn the key and the engine spins but doesnt fire try checking the timing for it to make spark at the time you need it to ,if it's out it wont catch and run or check for spark at the spark plug make sure it has spark use a dummy sparkplug in the boot and hold it on a ground and crank engine look for a blueish spark and if you have bare hands holding it you'll get a good jolt (insulated pliers)

Before you replace the ECU check to see that the fuel pump relay is working. It will be on the drivers side under the hood located just above the fenderwell. It should be mounted on a plastic piece with two other relays beside it. This relay is only about $ 16.00.

SOURCE: negative wire on coil to hook up tach on 1995

If you have a good look at the coil, it should still have a positive and negative sign on it somewhere. Try not let the extra wires confuse you too much. These are for the ignition module in the distributor. let me know if you need further clarification after you've had a look.

Where can i find the rpm sensor on a 2001 ford ranger

There is no tach - rpm sensor . This information comes from the PCM - engine computer .
The tachometer is a 6,000 rpm tachometer. It has four terminals labeled "B" (12 to 14.5V), "S" (EDIS tach signal in), and two "G" (cylinder selection grounds). The top ground (G) terminal is open on a 4-cylinder engine vehicle, and is grounded on a 6-cylinder engine vehicle.

  • The tachometer is inoperative
  • Powertrain control module (PCM).
  • Circuitry.
  • Tachometer.
  • Instrument cluster printed circuit.
  • Go To Pinpoint Test F .
  • Incorrect tachometer indication
  • Circuitry.
  • Instrument cluster printed circuit.
  • Tachometer.
  • Go To Pinpoint Test G .

Measure the resistance between the instrument cluster C220c pin 8, circuit 398 (BK/YE), harness side and ground.
  • Is the resistance less than 5 ohms?
Yes GO to G2 .

No REPAIR the circuit. TEST the system for normal operation.
Measure the resistance between the tachometer and the instrument cluster printed circuit terminals; refer to the following chart:
    Instrument Cluster Printed Circuit Terminal Tachometer Terminal C220a pin 13 C220a pin 15 S C220b pin 2 G C220c pin 8 G (6 CYL.)

  • Are the resistances less than 5 ohms?
Yes GO to G3 .

No INSTALL a new instrument cluster printed circuit. REFER to Instrument Cluster Printed Circuit in this section. TEST the system for normal operation. G3 CHECK FOR CLEAN TACH OUT (CTO) CIRCUIT OPEN OR SHORT Check for CTO circuit open or short. Refer to Powertrain Control/Emissions Diagnosis (PC/ED) manual.
  • Is the CTO circuit OK?
Yes INSTALL a new tachometer. REFER to Gauges in this section. TEST the system for normal operation.

No GO to G4 .
G4 CHECK FOR CORRECT PCM OPERATION Disconnect all PCM connectors. Check for:
  • corrosion
  • pushed-out pins
Connect all PCM connectors and make sure they seat correctly. Operate the system and verify the concern is still present.
  • Is the concern still present?
Yes INSTALL a new PCM. REFER to Section 303-14 . CLEAR the DTCs. REPEAT the PCM self-test.

No The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
Your best bet mite be to take it to a qualified repair shop.
