SOURCE: blowing number 19 fuse in the dashboard fuse panel

you have a dead short in the starting cicuit first thing is check any where you have had any other work done that might have pinched a wire.

Hello Steven.

The problem will most likely be between the ignition switch and the interior fuse panel if it goes as soon as you turn key to "on".
If it were after the interior fuse panel, the fuses within the interior panel would blow.

You will need to look at the wiring out of the switch for a short to ground. Perhaps the harness is rubbed through under the dash.
The gray/yellow, light green/pink and black/light green are the ones that power up when key turned on.

If it blows when the starter is tried look at the red/light blue out of the switch. This is what activates the starter circuit.
This circuit is also protected in the interior fuse panel so another reason I suspect the problem is under the dash near the ignition switch.
Check it out and let me know if you need more assistance.
Thank you for using FixYa.

Where is the purge control solenoid and powertrain relay located on 2004 Envoy SLT 4.2L?


Powertrain relay ? Maybe you mean IGN 1 relay ? This supplys B+ power to the coils . relay # 58 in the under hood fuse box .
Is there B+ voltage at the coil's pink wire ?

My 99 olds intrigue just won't turn over like my battery or something dead


How is the battery ? Do the headlamps shine bright ? Did you check the crank relay an the crank fuse 40amp ? one of the big one's ,maxi fuse . Under hood fuse / relay box . Check to see if voltage is coming through the transaxle range switch.

When the ignition switch is on, battery voltage is applied to one side of the crank relay in the underhood accessory wiring junction block through circuit 3, the PCM-BCM Fuse in the fuse block, and circuit 439. When the ignition switch is turned to START, voltage is fed to the powertrain control module connector C2 terminal 23 through circuit 5, the CRANK SIGNAL Fuse in the fuse block, and circuit 806 through the underhood accessory wiring junction block. Power is always provided from the CRANK MaxiFuse in the underhood accessory wiring junction block to the common side of the crank relay contacts. When the powertrain control module sees the crank signal and determines that conditions are OK for a crank, it supplies ground through circuit 625 to the crank relay. The crank relay now has both power and ground to the relay coil, causing the relay to pull in. When this happens, and the gear selector is in either PARK or NEUTRAL, the power at the relay common contact is passed through circuit 1737, the transaxle range switch and circuit 6 to the S terminal on the starter solenoid.
Passlock Theft Deterrent System
This vehicle is equipped with the Passlock theft deterrent system. This system contains a Passlock sensor. The Passlock sensor is part of the ignition lock cylinder assembly. The Body Control Module (BCM) interfaces with the Passlock sensor.
When turning the ignition switch to the START position with the proper key, the Passlock sensor generates an analog voltage signal, which is sent to the BCM. This analog voltage signal is of a specific value to the vehicle, and varies from vehicle to vehicle. When attempting to start the engine, the BCM compares a preset stored analog voltage value with the signal coming from the sensor. Because both values match, the BCM sends a fuel enable password via the Class II Serial Data Line to the Powertrain Control Module (PCM). As a result, the PCM enables the crank relay, and allows fuel delivery to the engine.
When attempting to start the engine by means other than using the proper key in the ignition switch, the Passlock sensor sends a analog voltage signal of a different value. The BCM compares the preset stored analog voltage value with the signal coming from the sensor. Because both values do not match, the BCM sends a fuel disable password via the Class II Serial Data Line to the Powertrain Control Module (PCM). As a result, the PCM disables the crank relay, and does not allow fuel delivery to the engine.
For more information regarding the Passlock theft deterrent system, refer to Theft Deterrent in Body and Accessories
This starting system is computer controlled , if you are not familiar with this I suggest you take a GM dealership or an ASE certified repair shop .

There is no reaction when turning the key to start the car


Turn key to On.
Turn on headlights manually... Do they come on?
Are there any lights on the dash?
If yes to these, battery is possibly not the sole problem.
Check for good, tight and clean connections at battery terminal posts!
If yes to above, continue on & get a helper... Turn key past on, to Start position.
Do you hear a click sound at time key is turned to Start?
If yes, then ignition switch is not problem, starter relay is getting power, and is now sending power to starter, but starter is not working.
Pic any No's... Then look there.
Good luck.

Ignition fuse keeps blowing when i turn the key


It MUST be the starter relay coil - or the power wire that feeds it. Likely a short in the relay coil (AKA starter selenoid).

NO Start the truck is not getting spark the coil is good but i'm not getting any power to the coil and I need to know if i'm testing it right i'm thinking it is the ignition


THE POWER TO THE IGNITION COIL COMES FROM THE AUTO SHUT DOWN RELAY..THE AUTO SHUT DOWN RELAY IS GROUNDED BY THE POWERTRAIN CONTROLLER WHEN IT SEES CAM AND CRANK SIGNALS..WHEN CRANKING..HOLD YOUR TEST LIGHT ON DG/OR WIRE AT COIL AND HAVE SOMEONE JUST TURN KEY ON..YOU SHOULD GET POWER FOR 2-3 SECONDS..IF IT DOES,THE CIRCUIT TO THE COIL IS OK..CHECK ALL FUSES..FUSE 9 IN JUNCTION BLOCK INSIDE TRUCK,FUSE 3 IN UNDERHOOD FUSE/RELAY CENTER..CHECK FOR ANY FAULT CODES IN PCM..YOU MOST LIKELY HAVE A FAULTY CAM OR CRANK SENSOR..CAN BE MONITORED WHILE CRANKING ENGINE WITH A SCAN TOOL HOOKED UP..LET ME KNOW WHAT YOU FIND
