Question about 2002 Chevrolet TrailBlazer

1 Answer

My 2002 Trailblazer randomly won't start

Sometimes it starts fine, then other times it won't. It just cranks and sputters. No check engine lights come on, and it never misses or cuts out. Usually I can let is sit an hour after I tried starting it, and it will crank up just fine.

Fuel pump relay could be sticking, try touching it when the vehicle won't start, if it's overly hot try hanging it...

2004 trailblazer doesn't start on first try. It cranks and eventually starts but usually 3-6 tries. Once started it runs fine. I have no check engine light. We have replaced the spark plugs, b


For engine to run it has to have:
Fuel, air and spark.
So if it doesn't start, something's missing.
Is your fuel pressure OK? Is your spark present? Is ECM firing injectors?
Check all those basics and I'm sure you'll find what's wrong.

Car won't start. Sounds like the engine flooded. Not the starter. Also loses power going uphill and when accelerating.


Check Engine Light flashing when accelerating ,severe engine misfire . Something in the ignition system is breaking down under a load . If the starter engages an spins the engine when you turn the key to start an it doesn't start an run , it has no spark or fuel pressure . If you don't know this or how to diagnose .suggest you take your vehicle to a qualified repair shop . Pull two plug wires off the top of the same coil an crank the engine , if you do not see a spark jump from one coil tower to the other you have an ignition system problem . ignition module or crankshaft position sensor

2006 dodge stratus won't crank and cruise control won't light


Must not have been much of a mechanic. If the engine runs and sounds fine sometimes and other times it doesn't then it does not sound like a mechanical problem with the engine. Sounds more like a issue with either the ignition system or fuel system.

My blazer trys to start but wont turn over and its not every time some times it will some times it wont. i had the fuel filter changed in it cause someone told me to try that but there is no differece.


by not turning over i`m guessing that you mean the engine won`t crank over,if you mean won`t start when the engine turns over then that is a different path of diagnosis.if you mean that it starts to turn crank over but stops almost immediately then this could be a weak battery,or bad starter with a bad spot in the starter,that`s why it will start sometimes and sometimes not as the starter hits and misses stopping on the bad spot.if you mean it cranks over fine but will not start then this could be a fuel pump going bad,a dirty throttle body,a bad crank of cam sensor,these usually set a code in the computer and sometimes turns on the check engine light sometimes not.you should have the computer checked for codes to see if there is any,or just a wiring problem for the ignition system
