Question for those that are more handy at auto mechanics than I am -
1994 Dodge Dakota 2WD
3.9L Engine / 5-speed
Ran fine - stopped in driveway overnight. Will not start. Starter engages. Engine does not turn over. I have fuel flowing. No spark. So far, I have replaced in the following order:
Plugs
Plug wires
Distributor cap / Rotor
Crankshaft position sensor
Ignition Coil
Pickup Coil
I think I have covered everything that should affect spark. Still no spark.
I am open to suggestion before I have it towed someplace for a more experienced person to have a go at it.
Do you have power to the coil with the key on? Do you have power to the ECM? You have covered all the normal stuff.
Check all the connectors for a loose connection.
I agree on sometimes overlooking the obvious. I did gap the plugs. As previously mentioned, there are no points. I did shoot starter fluid into the throttle body just to make sure it was not a fuel issue.
I am not a mechanic, but if your car was running fine the night before, I doubt your problem requires a tune up. Tune up problems are usually gradually evident.
Since your engine won’t turn over, I’m curious as to how you’ve established that you get no spark.
I’ll assume that you don’t know for sure and if that is the case and you are satisfied with the fuel and the fuel flow, you might check the timing chain/belt.
Good catch The Flying Dutchman, I read the stater engages, and skipped to fuel flowing.
What do you mean that the starter engages, but the engine does not turn over?
Do you mean the engine does not catch, it just cranks? Or do you mean it does not turn over and you don’t the rowr-rowr-rowr sound when the key is turned to the start position?
Hope you don’t mind making a brief clarification - you mean that the engine turns over but does not catch, because you have fuel, air, but no spark? You’ve done the old “screwdriver in the plug boot, arcing to the engine block while cranking” to verify that there’ no spark?
Or do you mean that the engine does not turn over at all, even though the starter solenoid engages the starter? If a car has the second symptom, I would guess a low/weak battery or a corroded connection. Particularly since it was running fine just the night before.
Otherwise, I’ve got nothing that’s not already been tried or suggested.
You mentioned that you changed the spark plug wires. Did you install them in the correct order on the distributor?
Also, check the distributor cap. If you removed it and then put it back rotatated by 180 degrees the car won’t start and flames will come out of the intake.
Is that even possible? It’s been a while since I worked on any cars with a mechanical distributor, but the ones I recall all had the caps keyed to a tab on the distributor body so they could only be installed one way.
On most 4 cylinder engines the cap is perfectly symmetrical so it can be installed both ways. And if you install it the wrong way you get flames coming out of the carburetor. I know because I’ve done that mistake in the past.
I’ve never tried to rotate the cap on a fuel injected engine, but in theory you should still get flames out of the intake.
I personally did the “screwdriver in the plug boot” thing. No arc to the block.
Plug wires were replaced one at a time, each replacing one as it came off the plug & the distributor.
The distributor is exactly in the same orientation as the previous one - and there was a notch to prevent it from being otherwise.
This is a 3.9L - 6 cylinder.
The battery does not seem to be the issue (although I am not claiming to be the expert). It does crank, the engine just does not fire. Wouldn’t that be indicative?
It was strong when I was first attempting to get the truck to turn over. Of course, it has been getting less strong as I have been trying to find the cause for it not firing though. I am not thinking that is it.
LOL I have one of
