When you check for spark, are you getting a good blue spark?

I have not pulled a spark plug out, but we did use a screwdirver in the wire but things are so corroded that we didnt get a spark I think due to a bad ground. Also ive been researching how to test the ignition coil and I think we kinda did it today as well we wernt getting any readings but we may have been doing it wrong. Also do you know the correct resistance for the coil and wires? Im kinda leaning twards the coil cus I was told if there going bad then they may work when its cold but when they warm up they quit. Thats kinda sounding like it but I dont know yet. I wanna be sure how to properly test it out. Thanks for responding so quick, sam

Hello,

Ok, what color is the spark? It should be a Bright Bluish/white. If Orange it is weak and will cause a no start problem.

Also since cap and rotor were worn how about the plugs. If cap and rotor were worn then I would have also replaced the plugs.

Also check the wires if cracked or look like original I would replace them also.

Would also check Fuel Pressure and Regulator. Check link below for video on testing....

My truck ran fine a day before, this morning I came out and it wouldn't start. It has gas, it has spark and the starter sounds fine. I put gas down the carb and still nothing. Any ideas?

Hi:
How did you check for spark? If you provided the fuel, it should at least try to start. Let me know exactly what you have done so I can help you determine the problem.

Hey Joe,
I pulled one of the plug cables and put a spare plug in and had it against metal. Tried to turn it over and it sparked.

Hi:
If there is spark, we need to check for fuel pressure. Can you hear the fuel pum run for a second when you first turn on the key? Is there any way you could check the fuel pressure? Some parts stores will lend tools.

Also, have you tried using starting fluid to see if it will start?

Hi:
Is it hot where you are? If so (I'm jealous. I hate winter anymore) lol. If it's hot, it could be a vapor lock. If the car is running now, have the computer scanned for trouble codes. Most parts stores will do it for free, and it may identify the problem.

Let me know what you find.

1999 Dodge Dakota 6 cyl Two Wheel Drive Automatic

Here's my problem. I went out to my truck and start it. It fired right up with no problems. I got a phone call and had to run inside for a moment, so I shut the truck off and took care of business and when I returned 15 min. Later I could not start my truck. When I turn the key in the ignition, I can hear the relays click, but nothing happens. The starter does not engage what so ever and the weird part is that the ABS and brake lights come on and stay on for about 15 sec. Then go out. I have checked the wiring going to the starter and everything is fine there. The fuses in the fuse box are all intact and I have tested the fuses and relays in the power distribution center to make sure that they all work and they do. I have read online that this may be a bad rear speed sensor, but I don't believe that that is the case here since the symptoms are not the same. (My ABS and brake lights do not stay on and my speedometer is working fine.) Does anyone have any ideas on what it might be? Any help would be greatly appreciated.

You may have a bad starter. Have a helper turn the key to the start position while you check for voltage to the smaller wire on the starter. It should get 12+ volts. If it does, replace the starter. If not, check the relay block to make sure the is power to the starter relay. If there is, switch the relay with one that has the same part number to see if the relay is the problem. If there is no power to the relay, chances are the switch itself is the problem.

Let me know what you find.

I have traced the wiring checking the voltage along the way and there is 12v DC to the starter when the key is turned. My neighbor told me that if I take it to auto zone I can have it tested, so I have removed it and will let you know the results. Thanks for your fast response.

I look forward to hearing from you. If you were getting 12+ volts to it when the key was turned to start, the starter is bad.

Let me know. Also, and don't laugh, if you haven't removed the starter yet, smack it with a hammar. Usually, that will jar it and make it work. (It's worth a try) LOL.

1999 Dodge Dakota Pick Up Truck with an 8 cyl, 5.2 ltr.(318 cid) fuel injected automatic but has some sort of throttle body atop the engine. Having trouble starting when cold. I have a block heater installed, which after 2 hours, or so, of being plugged in, the truck starts fine. Would the "Throttle Position Sensor" cause this hard start? Why does the engine have to be slightly warm in order to start correctly? Is there some sort of choke system within this throttle body that isn't operating properly? Is it in fact a throttle body? The truck runs perfectly fine other than this little dilemma, so I know it's not fuel pressure issue. Need a clear response from someone who knows. Thank you.

No choke. All that's in the throttle body is the throttle valve and a controlled air passage around it to adjust idle speed. You shouldn't need a block heater. The first thing to look at is if you get a nice idle flare-up to 1500 rpm for a few seconds after starting. If you do not, chances are the battery was recently disconnected or run dead and the Engine Computer has to relearn "minimum throttle". Until that happens, the computer won't know when it has to be in control of idle speed. The engine should start if you hold the gas pedal down 1/4". If that works, to meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals. You could also have fuel pressure bleeding off while the engine is off. To identify that, cycle the ignition switch to "run", wait a few seconds, turn it off for a few seconds, turn it on again, then maybe even a third time, then try to start it. If that works, the most likely cause is a leaking injector but the fuel pressure regulator and the check valve in the pump can cause that too. A rare possibility is worn bushings holding the distributor shaft. If the shaft wobbles enough there can be a signal dropout from the camshaft position sensor. When that signal is missing, the Engine Computer won't turn on the automatic shutdown (ASD) relay which powers the injectors, ignition coil, and alternator field. You'll be missing spark when it doesn't start and the injectors won't be firing either. Besides checking for spark you can also measure the voltage on the dark green / orange wire to the ignition coil or any injector. You should see full battery voltage for just one second after turning on the ignition switch, then it must come back during engine cranking.

Truck ran fine two days ago, went out to start it. But it will not start. Starter is engaging and sounds like it is cranking fine. Did finally get to start when I hold gas pedal to the floor, but as soon as I let off it dies immediately.I do not know if it is related to problem but over the last month the truck has died on me several times when I came to a stoplight. Also the radio has been reseting itself every time I shut off the truck, and headlights are flashing slightly within the last week.I know this sound like a complete mess but I am hoping somebody can help. PLEASE!

Do you have a check engine light? Try checking the fuel pressure and comeback with the readings this is where we start. Also check the idle air control valve, throtte position/mass aiflow/manifold absolute pressure sensors

Truck ran fine two days ago, went out to start it. But it will not start. Or you can try below to determine if its fuel or spark and then comeback

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil, distributor pick-up coil, ignition control module, cam and crank sensors-

When turning over in the morning sounds like battery is dead and will not start unless you depress the gas pedal. The battery has checked out ok, the diagnosis said that all sensors are working. Sometimes it will not start at all. If engine is warmed up it will start normally. Help!

Hi:
It sounds like the starter may be going bad if it isn't turning the engine over. Have a starter amp draw test done at a nationally recognized parts store. Most do it for free.
