As with any no start problem, you would need to check for power to the coil and the other ignition components.
It could be a relay or it may not have anything to do with changing the battery.

Check for a bad distributor cap and or rotor..........a bad cap and or rotor can caues firing (cross fire)across the terminals and introduce spark to the wrong cylinders at the wrong time.......
hope this helps.....good luck!

SOURCE: 95 gmc safari replaced fuel filter van ran great now wont start

Since you replaced the distributor, are you sure it's properly timed? Hook up timing light and try to crank. It should show you where your timing mark is. It will also verify that you are getting spark.
You need to start a systematic check. Is it electrical, mechanical, fuel related? Need to do more checking and maybe we can get that puppy going.

Good Luck

SOURCE: My 1999 GMC Sierra wont start. It has the 5.3l V8

Sounds like a security problem that is preventing starting. It will run for a few seconds and then die.

SOURCE: 2001 GMC Safari. Changed spark plugs, rotor cap

Try changing the fuel filter and checking the fuel pressure at the shredder valve. The readings should be 60 to 65psi with the fuel line pressurized with the engine not running, once the engine is running. It should drop by 5psi. Start with the simple things first. Keep me posted, be glad to help.

use some starting fluid, spray a little bit in the carburetor then try to start it, it should start,if not check for spark at the spark plug and there is a little valve on the fuel rail it has a black cap on it looks just like a cap on the tires take the cap off and push the pin in and see if gas comes out if you have spark and gas it should start

I have a 95 honda civic ex,wont start.ran fine yesterday,wont start this morning.battery is fully charged,new cap and rotor.would do u think might b my problem


if it wont turn over 1st check the ground s on the car and the battery 1st. your battery can be fully charged and the car will not start even over night this can happen. then look at the starter. Note: if you have over 109K on the car and the timing belt has never been replaced you will need to have this checked as well.

Sounds like a faulty fuel pressure regulator, or possibly the MAF sensor.

Car will start sometimes other times i will have to continue to crank the engine it cranks everytime


As it cranks, is there white or black exhaust smoke ?? If yes, the fuel injectors have solid build up on the tips. Normally, a quart bottle of injector cleaner treats 20 gallons. Pour 5 to 7 quarts of fuel injector cleaner. With cold engine (been parked for at least an hour or overnight), while cranking engine, have 2nd person spray starting fluid into air filter. DO NOT PRESS ON GAS PEDAL !!! Let the starting fluid do its job of starting the car. Starting fluid is highly combustible, so its important you don't give any gas while its cranking and 2nd person is spraying into air filter. When engine starts, stop spraying starting fluid and give a little gas. If engine begins to die, immediately spray a little starting fluid again. When engine begins to run, let it run a few minutes to let fuel injector cleaner to do its job (loosen solid carbon build up on tips of fuel injectors).

I have a 1997 Tahoe 5.7L 4 door model that ran fine all day. Next morning it wouldnt start. It will try to turn over but wont crank. The fuel pump does engage, filter is clean. Fuel flow goes to injectors...


Well,first off you need to make sure you are getting spark to the spark plugs first.Get some insulated pliers and pull off a spark plug wire,hold it next to the frame or exhaust and have someone spin the engine over.You should see spark jumping between the plug and the ground.If you do not,then you have an ignition problem.If you can spray fuel in the intake and it wont even try to start,then it sounds like you have an igniton problem.Verify that before going too far with the fuel system.If you have spark,then it may be your ECM could be fried and is not letting the fuel injectors open but it should still try and start if you are spraying fuel directly into the air intake.IF it has spark.

99 yukon 180,000 mi. doesn't start. cranks forever, but won't start. Should I be able to hear the fuel pump when I turn on the key?


yes you should be able to hear the fuel pump run for about 5 seconds once the key is turned to the on pos. check to make sure you have spark. if you do try having someone spray air intake or carb cleaner into intake manifold while you crank. If the truck starts right up for a second (or stays running as you keep spraying) Id say you have a bad fuel pump and id change the sending unit also. (First check the fuel pump fuse and fuel pump relay) GMC and Chevy are nororiously known for having bad fuel pump/sending unit problems. I have prob changed over 60 myself.

Engine cranks but wont start. may start but immediately dies out


hi i dont mean to sound harsh but never assume anything with cars, if the engine cranks but wont start check for a spark at the plugs if no spark then you know that the problem is ignition or electrical in nature. if you have a good spark then you need to find out if you have fuel to the engine a good trick which i use is to spray some carb or injection cleaner into the manifold via a vacuum pipe dont spray it down the intake you might set yourself on fire ! if the engine kicks and attempts to run you know its a fuel fault . come back when youve established this.

2002 Dodge Durango won't start?


fuel pump is working?and how about spark ign coil? I recommend investing in spark tester! also sit in side windows up nice and quite turn key all the way do not crank it! do you hear grrrrrr that would be your fuel pump no grunt no pump if so!! I would consider looking into no spark if I were you good places to start!

Not starting


Air/fuel/spark. check the 3, and then do a dummy test. I know , im not insulting you, but my dakota wont start if my gascap isnt screwed down all the way, it throws a sensor and it wont start. So just do all the dummy stuff you know has to be done to start it, put it in park, close all the doors, stuff like that, never know, could be something simple. if not, as above, Air/fuel/spark. need all 3 to start an engine.
