When I first start my truck it's fine but after about 30 seconds it's starts missing real bad and won't go but vibrates like son of a bitch. And it has no power. I just did a tune up, including distributor cap and rotor button. What is wrong with my truck? Please help. Haha

 

Unplug the front O2 sensor, and see if the problem goes away.

Welcome to DF!

 

It didn't work. Any other option?

 

Check engine light on? Getting any codes? How many miles on the truck? Any other work been done to it lately?

 

Firing order wrong? Or rotor or distributor cap on wrong

 

None of that. Firing order is right distributor cap is on correctly. It's got 130,000 miles and nothing has been done but the tune up. Could it be my fuel pump?

 

Entirely possible, put a fuel pressure gauge on it, and see what it thinks. (you can rent one from any of the big chain parts stores.)

Could also try physically removing the O2 sensor before the cat from the exhaust, and see if that helps at all. (clogged cat?)

 

The fuel pressure gauge said 0 lbs of pressure but it still runs, very ****ty but it's gettin fuel none the less

 

Is the gauge working? On a 2000 truck, it's wants 49 PSI at idle....... With zero pressure, it shouldn't run at all. Make sure the gauge has the little feller in the fitting that opens the schraeder valve. Also make sure you are screwing it down far enough.
