1995 Ford Ranger 2.3 after driving for a little bit fails to start. Remove 30 AMP fuse for computer will start. Ourchased ignition control module unable to locate. Looked on manifold near battery and can't locate.

Your ranger doesn't have a ICM - ignition control module . PCM - engine computer controls spark .

Keith, 1995 ford ranger, looks like interior light fuse is # 27, 10 amp. in interior fuse box panel and module #3 in under hood fuse/relay. Pg. 308 to 315 in the attached manual show fuse locations for all. Check the attached links,instruction and guides, Good luck

The large MAXI fuses in the engine compartment fuse block are the MAIN fuses. They supply voltage to several other fuses or circuits.

MAXI Fuse #13 in your 1996 Ford Ranger is supposed to be a 30 Amp fuse (not a 50 Amp) according to the power distribution diagrams as well as the fuse block detail diagram. This fuse supplies voltage to the Powertrain Control Module (PCM) power relay and to the oxygen sensor heater circuits.

Please note that it is NORMAL for this fuse to cause a draw on the battery during vehicle operation and also after engine shut down. The OBD-2 oxygen sensor heater circuit monitors run after engine shut down and key off. This can take up to 45 minutes to complete. After the O2 heater monitor has run, the PCM will go into sleep mode.

When the PCM goes into sleep mode, the battery draw from this fuse will be reduced greatly. If you are performing "ignition-off-draw" tests trying to figure out why the battery keeps going dead, it is best to use an ammeter that has a 1 or 2 amp scale. You should set-up for the test using a shunt bar. Wait for 45 minutes to an hour for all of the computer systems in the vehicle to go into sleep mode, then open the shunt. Your computer memory, radio pre-sets, clock, etc. will continue to draw without ever shutting completely off. Any draw under 300 Milliamps is considered "acceptable". It is my experience that most vehicles have an ignition-off-draw of somewhere near 150 Milliamps.

The underhood fuse box diagram can be found on page 314 in the 1996 Ford Ranger Owner's Manual.

WHEN A FUSE BLOWS YOU HAVE A SHORT OR SOMETHING SHORTING OUT IN THAT CIRCUIT.MANY THNGS CONTROLLED BY 30 AMP FUSE PCM POWER RELAY, POWER WINDOWS.LOOK ON FUSE DIAGRAM COVER FOR 30 AMP FUSE THAT BLOWING SEE WHAT CIRCUIT THAT FUSE CONTROL OR LOOK IN DASH OWNERS MANUAL SEE WHAT THE 30 AMP FUSE CONTROL SEE WHAT CAUSING IT TO BLOW.

look behind the alternator by the ignition pack. it should be a plug on top

It sounds like your ignition module is failing after reaching a temperature threshold, this occurs when the component's sealed silicone housing dries out and tends to ground out or leak voltage. The component is located on the back side of the distributor housing if memory serves me on the V-6 engines they are a pain in the neck to reach and I am pretty sure the bolts that hold the ignition module to the side of the distributor are torx head machine bolts. If this doesn't fix the problem check the fuel pressure at the fuel rail it should read 30 - 40 psi or pressure if not replace the fuel pump.

It does not have an ignition control module. The PCM (powertrain control module) fires the coil pack based on signal it recieves from the crankshaft position sensor and the camshaft position sensor.

TEST B: BATTERY VOLTAGE OUT OF RANGE - DTC B1676
1. Check if vehicle has been jump started within past 2 weeks. If vehicle has been jump started, ABS is
okay. If vehicle has not been jump started, go to next step.
2. Using DVOM, measure voltage between positive and negative battery terminals. If voltage is 9-19 volts,
go to next step. If voltage is not 9-19 volts, diagnose charging system. See appropriate GENERATORS
article in STARTING & CHARGING SYSTEMS.
3. Turn ignition off. Disconnect 25-pin ABS control module. Install EEC-IV 60-pin Breakout Box (014-
00322). Turn ignition on. Measure voltage between breakout box terminal No. 20 and ground. If voltage
is more than 10 volts, go to next step. If voltage is less than 10 volts, repair Light Blue/Pink wire between
ABS control module and instrument panel fuse panel.
4. Turn ignition off. Measure voltage between breakout box terminal No. 25 and ground. If voltage is
greater than 10 volts, go to next step. If voltage is less than 10 volts, repair Red wire between ABS
control module and power distribution box/engine compartment fuse box.
5. Measure voltage between breakout box terminal No. 9 and ground. If voltage is greater than 10 volts, go
to next step. If voltage is less than 10 volts, repair Yellow/Light Green wire between ABS control module
and power distribution box/engine compartment fuse box.
6. Measure resistance between breakout box terminal No. 8 and ground. Also, measure resistance between
breakout box terminal No. 24 and ground. If both resistance measurements are less than 5 ohms, replace
ABS control module and repeat self-test. If either resistance measurement is greater than 5 ohms, repair
suspect Black wire between ABS control module and ground distribution.
NOTE: DTC B1676 will set if vehicle has been jump started.
