Obviously that the ignition you bought is broken or not fit with your car.

SOURCE: thanks for the help

thats weird mmmm make sure than you have power going to the black and pink wire or pink with black stripe wire when you turn the ignition on, i don't know what else to recomend you since im not close to the car but the only coming problems on these cars is the module or the crank sensor, did the module installed on it was new? or used? if not sure or even if is new call to auto zone
and ask them if they test ignition modules for free i belive they do and if tehy do take the module out and take it to them, for testing, also by the time you remove the igniton coils turn the ignition on, and make sure you are geting power to one of the coil conectors, and the only way to get to the conectors is by removing the coils, and if there is not power then your ignition switch or a lecttrical problem is present, also make sure to do a cotinuity test to the wires coming from crank sensor to ignition module, check them for open or short to ground

I have found the most common part failure issue with the ignition system is the crank sensor, also called by some the TDC sensor.

SOURCE: intermittent crank no start. intermittent shut

Check the number on the ECM . If it has the number 1228253 on it that is your problem. They had a cutting off problem while driving. Get one with the number 16198264 on it. The 1228253 is junk and gm replaced them with 16198264.

next time it won't run after it heats up, spray or pour water in crank sensor and see if it will start. I have seen new crank sensors go bad.

I have a 2006 chevy uplander when shut off no start batt dead and ignition fuse in bjb replace fuse and still no start or crank no power to cluster cluster dead on commute back

Need better info.
when shut off no start batt dead and ignition fuse in bjb replace fuse and still no start or crank no power to cluster cluster dead on commute back ????????? What about ignition fuse ? It was blown an you replaced it or you just replaced it ???? When you shut it off no restart ,the battery was dead ? Test battery , battery cable connections , charging system - is it charging ?
First off your probably unaware of how this vehicle works , This vehicle is powered up by the BCM turning on relays an sending commands over the serial data bus (network) ,do you know what that is ? The ignition switch is a low voltage input to the BCM .
Circuit Description (Key Start)
For ignition switch power modes refer to Body Control System Description and Operation . When the ignition switch is placed in the Start position a discrete signal is supplied to the body control module (BCM) notifying it that the ignition is in the Start position. The BCM then sends a message to the powertrain control module (PCM)/engine control module (ECM) notifying it that CRANK has been requested. At the same time the BCM is supplying 12 volts for the IGN 1 relay closing it and supplying battery positive voltage for the crank relay coil. The PCM/ECM verifies that the transmission is in Park or Neutral. If it is, the PCM/ECM grounds the control circuit of the crank relay. When this occurs battery positive voltage is supplied through the switch side of the crank relay to the S terminal of the starter solenoid.

Check the Ignition 1 relay -
Relay Controlled Power Mode
The body control module (BCM) uses the discrete ignition switch inputs ignition 1, ignition 3 and crank to distinguish the correct power mode. Once the BCM has determined the power mode selected by the vehicle operator it will energize the Ignition relay, Run relay and retained accessory power (RAP) relay, depending on which power mode is selected.
Ignition 1 Relay
The relay uses a Hot At All Times B+ power source derived from the underhood electrical center. The ignition 1 relay supplies a power signal to the following circuits when the Run or Crank power mode is selected:
• AC clutch relay
• ABS STG angle sensor
• Antilock brake system (ABS) yaw sensor
• Auxiliary power drop connector
• Crank relay
• Cruse control switch
• Electronic brake control module (EBCM)
• Engine control module (ECM)
• HVAC module
• Ignition control module (ICM)
• Instrument panel cluster (IPC)
• Sensing and diagnostic module (SDM)
• Transmission solenoid circuit

TRUCK CRANKS COLD AND SHUTS OFF AFTER15MINUTES

Ignition module ? Crank sensor ? You like making the part's store rich ? Have you heard about testing electrical circuits before replacing parts ? Maybe you should take it to a qualified repair shop !

Why does my 2003 pontiac sunfire lose all power while driving

That can be the symptom of a bad Ignition Control Module, or also a bad crank position sensor. The ICM can be taken off and tested for free at any parts store. The crank sensor circuit can be tested on the car with a multi-meter. Also small motors (like a fuel pump motor) that are starting to fail can sometimes work until they get hot and then stop working until they cool down again.

Next time the car shuts down and won't restart, check for spark on a spark plug wire with the engine cranking over. If you have no spark, suspect the ignition control module or the crank position sensor. If you still have spark, but won't start, check if the fuel pump is putting gas up to the engine.

My 1999 saturn sl2 will not start. It cranks, fuel pump is working but I no spark from the ignition coils or spark plugs. A few months ago the wipers started acting funny (going off when they wanted to)...

It could be, and almost definitely is very possible its the brain ( ECU or Electronic control module) Will all the things you said it is doing that is probably the problem. Caution : Computer problems are EXPENSIVE
