Fix truck

Haven't given anyone much to go on here. You have to start with some good old fashioned troubleshooting. Is the engine turning over (cranking)? If Yes, the battery and starter are good. Does it have spark? Pull a plug wire and test. If not, you have an ignition system problem. Does it have fuel? Starting fluid is the easiest way to check (remove air filter and spray a bit in to see if it starts). Does it have timing or compression?

Starter fluid started it. Now it's either the fuel pump or a regulater switch. What's the best way to check without tearing it all apart. And thanks for the trouble shooting advice. I can fix the problems when I know what the problem is.

For fuel related problems, next check the fuses and the relay(s) for the fuel pump. You can have someone listen to see if the fuel pump is working. The pump should come on for 5 seconds or so as soon as you turn in the key. If you cannot hear the pump (in the fuel tank), it could be a relay or a bad fuel pump.
