Im not getting any spark on my 2002 ford explorer 4.0


check the crank positioning sensor, other than that there should be a unit that sends signal to the coils make sure everything is plugged in.

2002 Ford Explorer ran out of gas put gas in and won't restart. replaced fuel pump and fuel filter still won't start. Cranks but won't start


Most Fords have a fuel reset button. When you ran out of gas you tripped the circuit. Most of the time the button will be on the passenger side by the kick panel. The exact location should be in your owners manual or your local library or auto parts store will have a copy of one for your specific vehicle.

Why is my 2002 Ford Explorer V8 cranks but won't start?


No spark or no gas. Are you sure the gas gauge acurrate? When you turn the ignition key from Off to Run, but not all the way to start, listen carefully for the sound of the fuel pump. If you don't hear anything, check the fuse. If the fuse is good the pump may be bad.

Remove a spark plug wire and hold the metal end close to [but not touching!] a metal ground [use a pair of insulated pliers to keep from possibly getting shocked. Have a helper crank the engine. If you see a spark, the ignition is probably ok, although that's not 100% certain, as the timing or dwell angle could still be off.

Good luck!

Why my 2002 Ford Explorer cranks but won't start?


two engine systems has things to do with this problem, fuel and ignition.

and/or
have a shop with scan tool to diagnose exactly the other problem(s).

2002 ford explorer runs really ruff, when idoling and accelerating,


If it hasn't had the spark plugs and wiring changed within 60,000 miles,I'd change them out.
Clean the MAF sensor with brake spray cleaner also.Don't wipe the sensor wires,though.They're delicate.
If this is not the problem fixer,then check for `ye olde vacuume leake',which always is a good guess when idling poorly. don-ohio

2002 ford explorer 4.0lwill turn over but back fires when trying to start


How many miles on engine? Skipped timing chain is possible, or bad coil pack and spark plug wiring.Nobody could've switched wiring positions to spark plugs on you,could they?
I suppose a crank sensor up front could do this?don-ohio

Have a ford explorer 2005 xlt having problem getting it to start, have change the fuel pump and fuel filter, also change the crank shaft sensor and the cam shaft sensor, still not starting can any...


Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they just stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.


Have you hooked a scanner to the computer and checked the oxygen sensor(s)? If they are bad they could lean out the engine. The MAF Sensor can cause starting issues. Check the filter side of the MAF Sensor for any debris. I have found feathers, leaves, rags, etc. in them.

Remember an engine needs three things to work properly...Air / Fuel / Ignition(Spark)
