SOURCE: spinning will not crank

It's fairly common for the pickups in distributors to go bad.

SOURCE: changed water pump on 1994 dodge dakota sport

I have a 94 dodge dakota sport 5spd. I had that same problem recently. Thought it was the pickup coil, so I changed it and my truck would still not start. And the rotor and there was still nothing. Then I changed the Crank Sensor and THAT was why it wouldn't turn over.

SOURCE: my 1997 gmc sierra has a hesitation problem change

Did you check the timing?

Mine would idle rough and hesitate. I replaced all kinds of parts before finding out it was a bad ECM (computer) I found a used one for 50 bucks or so that fixed it.

I have a 2000 gmc Sierra 3/4 ton 4x4 k series I have no spark to my spark plugs I have changed the crank sensor an the ignition module not sure what else I can try I'm thinking maybe the ignition coil


Check to see if you are getting spark from the coil to the distributor. I suppose the engine is a 5.7 liter?If not getting spark to the cap, then check for power and ground pulse at the coil.If there is spark at the cap, replace the ignition rotor. If there is no power or ground pulse at the coil,check to see if the ignition rotor is spinning when the starter is engaged. If the distributor is not spinning while cranking the engine there are several more things you'll need to check,i.e.,distributor gear and pin as well as oil pump if the pin or gear are damaged.

Ignition mystery! 1994 GMC Suburban 2500 5.7 mtr. No spark to spark plugs. Have spark from coil to distributor. Have changed coil wire, cap, rotor, ignition module, and coil. have 12.5 volts going to...


I guess you could have the ignition analyzed on an oscilloscope. Maybe a tech could see something then.
I always heard the only gap was the spark plug gap-the rotor has no gap-are you sure you got the correct rotor? And does it touch the top distributor cap coil wire tower?

Let us know. It is a mystery worthy of a solution.

Want to remove and replace the distributor in my 1997 gmc


1 Remove the plastic cover from the engine block with a wrench, then let the spark plug wires lead you to the distributor. It's at the back of the engine block.


2 Remove the negative cable from the battery at the side of the engine compartment; carefully pull the spark plug wires off the distributor cap so you don't damage them. Use a screwdriver to take off the coil leads from the distributor and the electrical connector at the bottom of the distributor.


3 Loosen the clamps and take off the distributor cap. Mark the parts to align the rotor position to the distributor housing and the housing to the engine block. This will help replace parts correctly during distributor installation.


4 Unbolt the distributor hold-down bolt with a wrench and remove the distributor from the engine.


5 Install the new Sierra distributor, aligning the marks for proper seating in the engine block. When ordering the distributor, give the parts dealer your model, year and engine size. You can order part number A1841639 from Parts Train for a 4.3L engine.


6 Re-install the distributor hold-down bolt. Replace the distributor cap and put the clamps back on. Attach the electrical connector at the base of the distributor, put on the spark plug wires and coil leads, and hook up the negative battery cable.

1996 gmc sierra not firing when weather is damp replaced distributor and cap rotorbutton


try changing the spark plugs and spark plug wires that may help...but first to be sure try following the ignition system from top to bottom...first try holding a spark plug wire half an inch away from your engine block and let somebody else try cranking the engine if you can't see a spark then try that with the wire connecting the coil with the distributor if there is still no spark than the coil needs to be changed
