2000 f250 powerstroke..... Truck blew the 30 amp fuse that controls PCM coil relay,Fuel Heater,Waste gate Solenoid,Injector Driver Module,Relay Coil,after driving 20 mins.


Did you replace the fuse ? If yes, does it blow after driving ? Sounds like you may have a main power wiring problem, could be shorting to ground. Do you have any codes or an engine light on ?

1994 Ford Ranger Starts runs for 3-4 minutes then dies, changed ignition mod, fuel pump, fuel filter, fuel pump relay,checked vac hoses, totally lost!!!!!


As with any no-start or stall problem you will need to figure out if it is a fuel or ignition issue.
The high idle usually means you have a vac leak or a problem with the throttle body or idle air control valve. The control valve is how the computer controls the idle speed.
You'll need to watch the fuel system and spark to see which is being affected when the engine dies.
You might want to hook a test light up to the coil to see if it is loosing voltage for example.

I have a 1990 ford f-150 4x4 that is not getting fuel to the engine. I have changed both fuel tanks and pumps, checked the fuel filter and relays. Please help.


A mechanic would check the injectors for voltage and for a ground signal from the computer.
The injectors get power from the EEC relay near the battery.
The ECM computer gets a signal for the coil and the injectors from the module mounted on the side of the distributor.

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Troubleshooting the no-start condition - from the 1990 Mitsu Mighty Max Repair Manual:

Priority Action Part Type -- Cause
1 Inspect Battery -- Battery Discharged or Faulty.
2 Inspect Battery Cable -- Corroded, Broken, Shorted or Poorly Connected Battery Cable.
3 Inspect Distributor Cap -- Distributor Cap Cracked or Burned.
3 Inspect Fuel Filter -- Clogged or Dirty Fuel Filter.
5 Inspect Ignition Coil -- Faulty Ignition Coil.
6 Inspect Wireset -- Worn, Damaged or Faulty Spark Plug Wire(s).
7 Inspect Spark Plug -- Incorrectly Gapped or Fouled Spark Plug(s).
8 Inspect Starter -- Starter Motor Faulty.
9 Inspect Fuel Pump -- Low Fuel Pressure.
10 Inspect Solenoid Switch -- Faulty Starter Solenoid Switch.
11 Inspect Fuel Pump Relay -- Faulty Fuel Pump Relay.
12 Inspect Fuel Injector Pressure Regulator -- Faulty Fuel Injector Pressure Regulator.
13 Inspect Ignition Switch -- Improperly Connected or Faulty Ignition Switch.
14 Inspect Starter Drive -- Faulty Starter Drive.
15 Inspect Fuel Injector -- Dirty or Worn Fuel Injectors.
16 Inspect Fuel Pump Strainer -- Clogged or Dirty Fuel Pump Strainerat.
17 Inspect Engine Control Computer -- Incorrect Operating Information Being Delivered and Sent From The EEC.
18 Inspect Fuel Tank -- Fuel Tank Empty.
19 Inspect Carburetor -- Carburetor Flooded or Faulty Choke.
20 Inspect Distributor -- Worn, Loose, or Incorrectly Installed Distributor.

Now that you've replaced nearly everything, the only thing left that I can think of is the oil pressure sending unit. If this is bad, the fuel pump shuts down, possibly causing the problem. However, before buying a new part, find the wire for the sender and ground it by attaching it to something on the engine. You won't indicate any oil pressure, but if this IS the problem, you'll know quickly. THEN go buy a new sending unit.

1984 bronco 2-runs 15 min shuts down wont start again for 20 runs


If the fuel filter is dirty it will settle when you turn the truck off. When it runs for a few minutes the debris in the filter will get sucked into the screen and stop the fuel from getting through. If it was a starter or coil, it would not start at all.
