Check fuses underhood first as one may have blown, then scan for codes. also circuit breaker 1a and 32 in the smart junction box. then check crank and cam sensors against new ones resistance wise

The old rangers had what was known as an inertia switch that would shut off power to the fuel pump, and also shut down spark in the event of an accident. Sometimes these switches would fail. If you can't hear the fuel pump cycle, I would look to see if the new rangers have something similar. Also, If both of these things fail, you could have a bad PCM relay. You should hear/feel it click when you turn the switch to the on position. Hope this helps.

Got stranded the other day. There's plenty of battery so the engine cranks but it just won't catch. Acts like there is no spark or fuel getting to the cylenders. It's happened twice now - both times during wet weather but there are no obvious signs of moisture anywhere in the engine compartment. The first time it started an hour later and then ran fine. This time it still won't start. Any thoughts on what it could be?

Have a helper crank it while you visually check for spark at the spark plugs. If you have spark everywhere, use a gage and check fuel pressure. You got to start testing, somewhere.

Put new coil, new plugs and wires, new heads, and injectors, but cylinder three has no fire. What could be my problem now?

Good afternoon.

I would start by doing a compression test to see if there is an internal issue with the engine.

Also, if you have a noid light, check the injector harness for the cylinder and see if there is a flashing light on the noid to be sure the ECM is grounding the injector to fire.

Okay, you need to go back and re check.

Go to basics. Is there spark at the plug?

Is the injector firing or being commanded to fire?

If you have a vacuum gauge, check the vacuum at idle and see if it is steady at 20 inches.

My Ranger shutoff a week ago on a thursday night all the guages showed normal operating conditions. I was driving and lost enginge power, tried shift gears and no go. Coasted to a stop and turn off all accessories, a/c and phone charger, engine cranked back up then. Three days later it cut off again same feel and situation this time it did not turn back on. Thought it was the fuel system so replaced pump, guage was out anyways, and fuel filter. I am getting plenty of fuel to my injectors and can smell it coming out of the tail pipe when trying to turn the engine over. So next step I decided to check spark, pulled the Number one plug and held it and wire next to exhaust manifold to see if I could get a spark to jump and did not get a spark. Plug looked good still and the wires are less then two years old. I think it might be the DIS ignition coil pack. Is there anyway to test it, and if it is not it what other parts of the igniton system could be affecting this?

I tried the using the test light on the wires mentioned and did not get the flashing light. I test my test light on other connections and it was working.

Your truck has a DIS (Distributorless Ignition System) so therefore it doesnt have an Ignition Control Module. Just to be sure before you buy anything, check ALL fuses, Underhood and Driver side dash. If all good or replaced and no diference. Call up a local salvage yard and get a PCM or Computer and you will be fixed.

I recently replaced the starter in my 94 ranger, 2.3 ltr 5 sp. The starter was bad and had to be replaced, and when we tried to start it, the truck just cranked and cranked without starting. I was hoping that my son didn't fry the computer by hooking up the positive cable last. Also I have an autoxray 2500 that would not read the computer at all, and the check engine light does not work when the key is turned on initially. Please help

Two ground wires coming from the battery for the fuel pump and the ecc was barely connected. After I connected them the truck finally came alive. I'm sure it was from my son and I tugging on the starter cables
