95 Chevy Blazer turns over but wont start

This sounds like a classic ignition switch problem. Make sure it is replaced and not the ignition lock cylinder!

The ignition module below the ignition key will fix the truck. A loose or worn connection in the tumbler box would sometimes cut off the power to items in the truck, the brain, the fuel pump... ect.

Ignition module is a little black box and wires below the ignition key, it is approx $100 to replace and truck runs ... no stalling or no start conditions anymore.

To replace the ignition switch

• Torx bits (get a set, you need 3 sizes) Inverted Torx ( a set is available at Schucks/Kragen/Checker

• Screwdriver

• A few zip ties

• Wire cutters

Remove the skirting under the dash area and steering wheel.

Disconnecting the yellow wire under the dash on drivers side for the airbag.

Leave the airbag alone if possible, it may not be necessary to remove the steering wheel.

Now remove the lower column cover with 2 Torx screws.

You will now have access to 2 inverted Torx screws that hold the top column cover in place.

Look on the top of the ignition cylinder housing and find the small hole.

Insert a small Allen wrench into the hole and turn the key to "run" position and the ignition cylinder will come out, now the top cover will come off, giving access to the ignition switch.

You will need the smallest inverted Torx bit for the 2 screws that hold the ignition switch in.

You will have to cut a couple of zip ties to free the wiring.

Now get a Torx bit and a 7mm socket and remove the lower dash panels to get access to the wiring harness.

You will need the 7mm to unscrew a bolt that holds the connector together under the dash. Just follow the wiring to see what I mean.

Once the connector near firewall above foot area is loose, you will see two plastic strips that run along side the connector. These are easy to remove and slide off, and are keyed so you cannot reinstall them wrong. Hope this helps.

i have a 1998 chevy blazer i been haveing problems with it for about a week now i replaced the fuel pump the spyder injectors spark plugs, spark plug caps and once i put the spyder injector in it it started right up now its doing the exact same thing and getting no spark what so ever i went and bought a new coil no spark hot wire a wire to the coil and still no spark try either to the carboarator nothing i have no clue what it is

The connector inside the plenum on the Vortec 4.3L Fuel Injected Engine. It runs the fuel injectors. They did not Crimp the stress relief part of the connector. Thr wires become worn and must be soldered or new connector. Symptons are Hesitation.Stalling, not starting. if you solder make sure you clean to remove all oils and fuel from new connection and tin the wires and connectors to insure good connections. This drove my nephew nuts for a week until we tracked it down.
