2002 blazer has tbl starting and staying started. It has been thourly tuned up by reliable mech. also when trying to start it seems to temoparily short out battery


You sure it seems to be a battery/electrical issue? Blazers are known to have their fuel pump go out after about 8-10 years. If it starts but won't stay on....thats not a battery issue. Its either fuel, oxygen, or the alternator.

1998 chavy. blazer cruise control & wipers stop working.


Start with the simple and check the fuses, the other place to move on to would be the cruse and wiper control switch on the leaver. You can buy the replacement leaver control at Auto Zone and they will have the step by step instruction for you to get the job done.
Good luck and keep us posted. You also my want to inspect the wire harness to your cruise control and wiper motor. The harness both run together on the drivers side along the brake boost and the connections my have some corrosion on it or just come loose.

At startup, car runs rough. After short time it clears up and runs ok. I put in Seafoam to remove possible moisture in gas.


Have someone start it for you in the morning while you stand behind the car. After it starts, smell the exhaust. See if it smells sweet, kind of like maple syrup. Also are you having to add antifreeze. If yes to both, you might have a head gasket starting to seep.

From a stand still if you accelerate hard vehicle starts vibra


Well, kind of short on description, issues typical in this complaint are misfiring and U joints.

To emininate the engine, does the vibration happen on power braking, without the vehicle moving?
