If you have good spark and good fuel pressure and arent unable to check fuel injector for output, you might want to spray some starting fluid into intake and see if vehicle starts. If it doesnt start at all there may be engine mechanical issues( jumped timing chain). Also, if catakitic is plugged it will not let vehicle start.. Start with your basic: spark( make sure your spark plug wires are routed correctly), fuel pressure, engine mechanical and catalitic.

My 1999 kia sportage cranks but will not start

check all fuses are good then if you have some intake cleaner or brake cleaner where the hose from the airfilter goes to the motor shoot some in the intake through the hose and does it start up this means fuel problem 80% points to fuel pump located in the rear under the back seatsthere is a little piece of carpet in a square just lift it up and remove the 4 screws this gives you access to fuel pump if it doesnt start no fire spark you have to test for spark from the coils under the intake remove cover and test if spark and fuel ok timing belt jumpped good luck

My car has fire all inside lights turn on but wont start seems like it wants to but wont

check for spark at the plugs although you say you have spark. then spray intake cleaner into intake while trying to start. if the car starts then you probably have a fuel pump problem.

Chevy 1500 no spark or dash lights

Check the positive battery cables. There are 2 on the pos side. Make sure both have a good connection. If the one going to the ignition side is bad, the vehicle will crank and not start. If there is voltage close to the battery, check for a bad fusible link in the wire

1986 4runner starts good just misses bad and wont accelerate

I would first start with the coil, distributor cap, rotor, spark plugs, and the spark plug wires. If that doesn't fix the problem, I would then change the fuel pump (located in the gas tank) and the fuel pump relay switch (located in the kick panel on the driver's side). If that still does not fix the problem, I would change out the Air Flow Sensor (located on top of the air filter box), and the Fuel Sensor (located where the air filter tube attaches to the intake manifold).

02 caviler.. cranks but will not start.. have replaced crank sensor,fuel relay sensor.ignition module as well as spark plug module... and replaced battery

Squirt starting fluid in intake and try to start if it starts and then dies you have a fuel delivery problem. Make sure you check the fuses for a blown fuse namely fuel pump or fuelpump relay. If it doesnt start after squirting starting fluid in the intake check for spark at the plug wires and coil.

2004 ttr-125 bike won't start period. installed new vavles because the exhaust valve was bent, cleaned the carb and timed the cam and piston to TDC. i have the exhaust pipe off so i can hear the valve...

after trying to start the bike, remove spark plug, is it wet or dry? dry means carb problem, wet ignition problem.gtting firm till half stroke is normal, as compression is increasing. also make sure you didnt set the cam on wrong stroke, like exhaust instead of compression.
