I just tryed to start my truck and It won't start. It was running fine last night. While I am trying to start it I get my Air Bag light. I replaced the fuses and It turns off. but after a few tryes of trying to start it the light comes back on! I dont know what to do. I have checked fuses and i have a new battery and Alt. Any Ideas????

Thanks guys

 

Does it crank?
Does it make a clicking noise when you turn the key?
No noise at all?
Any recent repairs?

 

Air bag light shouldn't make your truck not start . Depending on what your truck is doing it could be ,no spark,or no fuel ,your battery maybe too low to crank your truck over or the alternator isn't charging your battery. Your starter could be bad or maybe even your ignition switch or ignition relay ,maybe fuel pump relay. In other words it could be many things try and see if it cranks if it does then it's a fuel or spark/ ignition problem

 

No it does not crank.....No, No clicking noise. Its turns over but wont crank. No, They only thing I have done on this truck was a new radio.

 

does it start with your foot on the gas?

 

A buddy of mine said my fuel lines might be clogged or fuel filter and its cause it to not get fuel. It turns over but wont crank. When I try to start it, it turns over and My rpm gauge moves alittle. My Battery gauge is sitting at 14. I have open my throttle tryed spraying some WD40 down in and it didn't work. I don't think its my starter Because it does turn over.

 

It wont start with my foot on the gas.

 

Do you have spark? getting good fuel pressure at the rail?

 

See if fuel comes out if the fuel line as your cranking just be carefull if there is fuel then make sure your getting spark. allso check your grounds

 

One of our rams did the same thing, after messing with it for a day we figured out it was the crankshaft sensor. was fine the day before, next morning would not start. Also it threw no codes

Still not sure why it lit up the airbag light, but ours did the same

First we need to know if you are getting fuel and if you have spark
