1999 Olds Bravada about 100k mileage. Drove fine yesterday. Parked inside overnight, won't start now. Sprayed gas into the intake - no luck... What now? Help please?
Opened similar question earlier - adding more detail here now...
The engine cranks, it just doesn't start. I still have a half tank of gas in the vehicle. All power appears to be working. New Fuel pump within the last month - new fuel filter at the same time.
Had some recent issues which were never confirmed, or even repaired - see previous questions for those details if needed.

Sounds like a fuel problem, as in the engine isn't getting any fuel. Could be as simple as a fuel filter or it could the fuel pump.

Engines need:
Fuel
Compression
Spark at the correct time
If any of these aren't there... it doesn't run.
Spraying fuel in the intake getting no results = its not a fuel issue. it should have at least made a few "pops"
most likely you have lost the spark. There's a lot of possible causes but its easy to test. Pull a spark plug boot. Pull the plug. put the plug into the plug boot and carefully set it on the engine block so the plug's metal body contacts the engine. Have someone crank the starter and you should see the spark once every 2 revolutions of the engine. (about 1 time every 1 to 2 seconds when running the starter)
When you confirm there's no spark... then you start looking for the possible causes.
Pull the distributor cap and look at the badly burned rotor and cap contacts inside....

Well, from what you've indicated, you are not getting any spark to the spark plugs.
Either it's a broken timing belt, faulty cam/crank sensor, or some kind of fault in the ignition system.
It's tough to say.
Pull one spark plug wire and use a plastic handled phillips screwdriver stuck into the spark plug wire boot and the metal shank held close to something metal.
Have someone try to start it and watch to see if you are getting any spark.

You need to check if the plugs are sparking, air flow and fuel flow. If you added fuel then you should check the plugs first. If you are careful you can pull a plug out of the socket to check for spark just be sure not to get electrocuted.

(P0171 and P0174) The MAF (Mass air flow) Sensor is grimy or defective. observe: using "oiled" air filters would reason the MAF to alter into grimy if the clear out is over-oiled. there is likewise an argument with some automobiles the place the MAF sensors leak the silicone potting fabric used to guard the circuitry. There may be a vacuum leak downstream of the MAF sensor. (P0125) inadequate heat up time Low engine coolant point Leaking or caught open thermostat defective coolant temperature sensor i'd additionally verify the gasoline rigidity. i think of the gasoline clear out and/or gasoline pump is likewise undesirable.

I had a 1998 S10 Blazer. Did the same thing. It was a relay behind the glove box that went out. I hope this helps you.

Are the battery and alternator new? This happened to me in my 2000 S10. They both took a sh*t at the same time. There wasn't enough power to start the truck.

Can you here if the fuel pump is pumping, if not check the fuel pump relay. or check the starter relay.
