I installed an alarm on my truck and now it wont start. I unplugged everything that has to do with the alarm and still nothing. The battery is low but still cranks good. How can I check fuel? If anybody has any quick ideas please let me know.

Your battery may be to low to completely start your truck. To check your fuel pump, turn the ignition on but don't start the truck. Listen for a slight buzz like noise, if you hear anything your pump is activated.

Also check your fuses.

I hear some noise in the tank. Checked fuses by door. Are there anymore fuses? Where is the fuel pump relay? **** this sucks

Just went through this. Even if you can hear the fuel pump, it may not be putting out enough pressure. my 96 requires approx 45 psi to start and 30psi once running. An easy way to check is as follows... cycle you ing key on and off several times in rapid succesion without cranking. After about 5-6 cycles crank it over. Cycling the fuel pump several times fools it into building pressure. A parts man at NAPA told about this little trick and it worked. A new pump ia around $200-$300 depending where you buy it. Don't drop the tank...it's much easier to pull the bed. The whole job should only take 2-3 hours...
