Having problems with your 1999 GMC Suburban ?
1999 GMC Suburban Wont Turn Over
\015 My suburban wont fire,you turn the key and it just keeps cranking,ive replaced the fuel filter,spark plugs and the ignition coil. Ive heard it might be the fuel pump,but when i turn the key to the on position,i hear the pump kick on\015
It sounds like you have a security problem, I had the same thing it would fire and run for half of a second and then that was it if anything at all. Had the security system rebooted, now it starts and runs fine.
Could still be the fuel pump it requires a specific pressure to operate it may run just not enough pressure to operate the system
