Hey there! my girlfriend has a blazer 1998 (same car just chevy). since it doesn\'t turn over that can only be a few things. (1) starter (2) wires (3) terminals and battery (4) ignition switch. if it made the wow wow wow sound like it is try to start i would tell your its the fuel pump because i just fixed one of those "pain in the..." but i would suggest if a terminal broke off just get a new battery, its probably shot. then bring it to the autozone for a free starter bench test, tow it if need be if you have AAA. but i would start with battery, you cant fix a broken battery once it breaks it looses efficiency; just get a cheap "o\' at wallchart and if it doesn\'t work bring it back :P BUT FIRST CHECK YOUR FUSES!!!!! i cant tell you how many people throw hundreds at their cars to find out at the end it was a 1$ fuse or Switch. hope this helps i gave you a few things to check start with the cheapest....... one more thing if you have 100$ to spare bring it to a shop just for diagnostics. then once the problam is found fix it your self you\'ll save probably 200$ that way so you spend a little to save a lot best of luck!

SOURCE: truck will turn over but not start

Hi scorioleo, yes, check that the battery terminals are clean. U can clean them up with a wire brush/sandpaper, coat w/ grease to prevent future corrosion buildup. If the terminals have corrosion on them, it could result in the battery havng trouble turning the engine over. Is the engine turning over too slowly (even w/ new battery) in your opinion? Next to check is spark. Pull off a plug wire, if u have a spare spark plug around, attach it to the wire, place away from moving parts, have someone turn key, check for spark at plug tip. Do this out of the sun, and the spark should be easy to see. If u have good spark, next to check is if fuel is reaching spark plugs.After attempting to start several times (only turn key to start position for about 10 seconds, wait about 10 seconds, try again. This is because it's tough on the starter to just keep turning the engine over w/out start up), after several attempts, pull a spark plug and check tip, it should be wet w/ fuel. If it's dry after trying several times to start, u may need a fuel pump (but 1st I'd replace the fuel filter, if it's plugged up, u can have a no fuel at plugs problem). Check this out, give me the results of checking the above, and let me know what u find, we'll continue from there.

Did they do a fuel pressure pressure test to determine that its fuel pump? And if so what was the p.s.i.?It should be around 55 to 60 p.s.i. a few pounds under 55 p.s.i. Pump needs replaced, Your shop should have chk. this when it was there the first time. Did they by chance chg. the fuel filter, that can hinder it from starting too.

SOURCE: My 2000 gmc jimmy will not start. It will turn

Have you hooked up a fuel pressure gauge to the test port on the rear of the intake, drivers side. You can get a fuel pressure tester for about 40 dollars at a part store. It is a real good tool to have in your toolbox. If your Jimmy can't build 55 psi, it won't start.

SOURCE: my 89 gmc 1500 will not turn over

Did you check your ground wire?If ground is good check to make sure your solenoid wire which is purple usually if it is broke if not get a test light and have someone turn motor over to crank position and check if power there if so more than likely ground problem.If solenoid has no power move to fuses under drivers dash..

Changed spark plugs now runs rough and has thick white exhaust

Changing the plugs probably had nothing to do with it.
White smoke is usually a sign the engine is burning coolant or trans fluid. You might want to check those fluid levels.
If the coolant is low, you may have a leaking head gasket or intake gasket.

97 gmc jimmy cranks but won't start, have replaced everything possible but still won't start, most of the time the brake lights won't work, or the gauges goes crazy. I have changed relays,...

There are two basic reasons for not starting - no spark or no fuel, both of which are controlled by the ECM. You need to check error codes and these items - for the spark, test it at the cylinder 1 sparkplug; for the fuel check the pressure (if too high or low, problem!).

1992 gmc jimmy wont start unless i spray with starting fluid after it starts it will start every time untill the next day then i have to spray again ?

Fuel pump issue.--

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.
