I installed a new distributor and entire ignition for a 2000 Dodge Durango. It will not start.
New distributor, new cap, new rotor, new wires, new plugs, new modulator. I have spark at the plug. I have tripled check my firing order. but will not start.

It needs more than spark to run! You need compression and fuel too.Try spraying some throttle body cleaner down the intake while someone cronks it.If it runs on the spray,check the fuel sytem(maybe a bad fuel pump,pump relay,blown injector fuse,etc)
got to be ignition module ,check for feed to it and if you have a feed then check the earths and if ok just change it ,these thing can just stop when you turn engine off ,never seen one go whilst being driven .

Possible bad ignition wire from coil to distributor cap. Possible ignition rotor inside distributor cap shorting to ground. Possible no power to ignition coil
That would be the ignition coil, the part that creates spark at the spark plug. If you follow the electrical path from the coil wire to the distributor cap, and from there, the spinning rotor just under the distributor cap carries the path from the coil wire at the cap's center to the spark plug wires around the dist. cap, and through the plug wire to the spark plug. The high voltage causing the spark is created in the ignition coil by the engine computer at the precise right moment signaling an ignition module to cut 12 volts current to the ignition coil. This causes the coil to internally build up high voltage which is passed through the coil to distributor cap wire. The computer knows the precise right moment to initiate spark from engine sensors, primarily the crank position sensor and the cam position sensor.
Whenever a high tension wire is removed for any reason from a spark plug, coil or distributor cap, or a new high tension wire is installed, Silicone Dielectric Compound WA-10, D7AZ-19A331-A (ESE-M1C171-A) or equivalent must be applied to boot before it is reconnected. Using a small clean tool, coat entire interior surface of boot with Silicone Dielectric Compound WA-10, D7AZ-19A331-A (ESE-M1C171-A) or equivalent.
Insert each wire on proper terminal of distributor cap. Ensure wires are all the way down over their terminals. The No. 1 terminal is identified on cap. Install wires starting with No. 1 terminal.
Remove wire retaining brackets from old high tension wire set and install them on new set in same relative position. Install wires in brackets on valve rocker arm covers.
Connect wires to proper spark plugs.
Install coil wire.
Installation of distributor
Before installing distributor, visually inspect distributor. Inspect O-ring. It should fit tightly and be free of cuts. The drive gear should be free of nicks, cracks and excessive wear. Rotate distributor drive shaft. It should move freely, without binding.
To install distributor correctly, No. 1 piston must be at Top Dead Center (TDC) of compression stroke. Remove No. 1 cylinder spark plug and rotate engine clockwise until No. 1 piston is on the compression stroke.
With No. 1 piston on compression stroke, align timing pointer with TDC on the crankshaft damper.
Align locating boss on rotor with hole on armature. Fully seat rotor on distributor shaft.
Rotate distributor shaft so blade on rotor is pointing toward mark on distributor base, that was previously made in Step 2 of the Removal procedure.
While installing distributor, continue rotating rotor slightly so leading edge of the vane is centered in vane switch stator assembly.
Rotate distributor in block to align leading edge of vane and vane switch stator assembly. Verify rotor is pointing at No. 1 mark on distributor base.
If vane and vane switch stator cannot be aligned by rotating distributor in cylinder block, remove distributor enough to just disengage distributor gear from camshaft gear. Rotate rotor enough to engage distributor gear on another tooth of camshaft gear. Repeat Step 1 if necessary.
Install distributor hold-down clamp and bolt. Tighten bolt, but leave it loose enough to rotate distributor.
Install distributor cap, No. 1 spark plug and ignition wires. Check that ignition wires are securely connected to the cap and spark plugs. Tighten distributor cap hold-down screws to 2.0-2.6 Nm (18-23 lb-in).
Reconnect distributor to wiring harness.
Set initial timing according to procedures found in Section 13A of the Powertrain Control/Emissions Diagnosis Manual .
After timing is set, tighten distributor hold-down bolts to 23-34 Nm (17-25 lb-ft).
I WOULD REPLACE DISTRIBUTOR CAP AND ROTOR.MARK LOCATION OF ROTOR OR MAKE NOTE SO YOU CAN INSTALL NEW ROTOR IN CORRECT FIRING POSITION. IF THIS CAR HAS A LOT OF MILES I WOULD REPLACE DISTRIBUTOR CAP, ROTOR.SPARK PLUGS AND WIRES.REPLACE IGNITION COIL.CLEAN FUEL INJECTORS, FILL GAS TANK UP TO 3/4 TO FULL TANK OF GAS POUR CAN SEAFOAM IN FUEL TANK IT WILL FLUSH OUT THE FUEL INJECTORS WHILE ENGINE RUNNING OR DRIVING CAR. REPLACE FUEL FILTER. REASON I SAY DO A TUNE UP PROBLEM COULD BE MINOR FIX.COULD NEED TUNE UP.IF TUNE UP DONT HELP THEN YOUR PROBLEM IS DISTRIBUTOR OR THE CAMSHAFT SENSOR INSIDE OF DISTRIBUTOR.THAT WOULD SET OFF CHECK ENGINE LIGHT.BUT I WOULD SAY TUNE UP COULD FIX PROBLEM.
he pick-up coil/stator assembly is located under the distributor cap, and once the distributor cap is removed from the distributor, just remove the ignition rotor, and then simply un-plug the wire connector to the the pick-up coil/stator and then lift it straight up and away from the distributor, and when re-installing the pick-up coil/stator be sure to align the square tab and the rounded tab on the pick-up coil/stator to match with the distributor housing and with the distributor cap and install the ignition rotor and the distributor cap, and then re-connect the wire connector to the pick-up coil/stator.

To Install: NOTE: Do not use the old cap, CMP sensor, and rotor screws. Use the replacement screws that have been coated with a thread locking compound.
Insert the CMP sensor through the reluctor wheel slot
check the camshaft position sensor inside the distributor. remove the distributor cap. take a volt meter and use either a paper clip or a small pin to insert into the back of the distributor connector (yellow wire). connect the positive side of voltmeter to yellow wire. rotate engine with starter until the rotor is pointed toward the rear of vehicle. with the ignition on( engine not running) the voltmeter should say 5 volts. if there is no voltage check the voltage on supply wire . with the key on there should be approximately 8.0 volts. if voltage is presant, install the probes of the voltmeter into the signal wire (tan/yellow) and crank the engine over to observe the voltage reading. the meter should read 5.0 volts indicating that the ignition signal is pulsing properly. if the camshaft sensor fails either test (replace it).
Disconnect the wires and take pictures with cell phone for reference to ensure you don't cross them when reinstalling the new distributor cap. Remove the two torque screws in the distributor cap and remove the distributor cap to access the rotor. Remove the rotor by lifting straight up and inspect the distributor for any condensation and corrosion. Clean the breather screen at the bottom of the distributor before installing the new rotor which just slides back in place. Install the new distributor cap and tighten the new torque screws, make sure you do not over torque the screws since the distributor housing is plastic and prone to stripping. Reattach the spark plug wires and start the engine and idle for 5 min and go for a test drive. Good luck and you may want to also buy spark plug boot lubricant to ensure the spark plug wires are fully installed when placed back on the new distributor cap and recheck connections after test drive. Keep me posted, be glad to know your blazer is running 100% and please rate.
the old fashioned way to check this is to remove your distribution cap and watch the position of your rotor arm to see which position it is for cylindar 1. then take out the spark plug for cylider one and use a light to see inside you should be able to see the piston move up and down throgh the hole, now the piston only goes down twice in one cycle so by cranking the engine round by hand you can correspond where the piton just starts to go down is the point of ignition so the rotor arm should be at the same point lined up with the spark lead for cylinder one inside the cap. if it mile off then cylinder 1 is at the top of the induction stroke, so crank round again until the piston starts to go down again. then you have the distributor arm at the right position, then follow round the cap the firing order for your engine. and then wire up the cap the same way.
