In my 1999Silverado it was the fuel pump and beware of the after market fuel pumps the may be cheaper but I had to replaced the first cheap one with a original Chevy pump after 3 months. The original guaranteed for the life of the vehicle but it is not cheap.
Probably the fuel pump.
check if it is getting fire
IT TURNS OVER BUT WONT FIRE
you ain't got no gas in it.
First you must know whether or not it is getting fire, fuel and compression.
If it turns over, try ignition module. If it turns over real free, then timing belt. If it doesn't turn over, then check starter/battery cables/solenoid/relay.
I have a 1996 Z71 with a vortec 350. It has a new battery and starter but turns over very hard. I can get it to start with a jump but not without. What am I overlooking?
Check and clean your spark plugs that might be the problem.
sell the piece of junk!
It is there if the vehicle over turns, perventing fire and explosion
Need a little more info. Is it trying (but failing) to turn over? What's it doing? has new battery and relay. just filled up the gas tank, it turns over and turns over, but wont fire. ends up wearing the battery down. even with a battery charger it wont fire.
crank sensor is bad
