Well, my big dillema is that I'm moving out next week, and I can't get my truck to start. I knew this was going to happen. I just changed my spark plugs and then it would start for 2-3 seconds, then die. I changed them one at a time, the firing order is correct. I just replaced the old plugs into the engine, and still the same thing... but now it's backfiring when I try to give it some throttle when it's dying.

I took the air filter lid and some hoses off to get to the 3 driver's side plugs, but put everything back. The plug wires seem to be in good condition, but it still sounds like it's missing and then dies.

PLEASE! help me. I need this truck to run before the weekend is up or I'm #$(*ed.

hey...

this sounds familiar... lol....

Sounds like you still have a hose disconnected, causing a vacuum leak. Check the large mass of hoses on the passenger side.

I had a problem like this on my pickup. When I replaced my plugs, I didn' replace the wires. The wires were old and when I started moving them around to change the plugs, I must have snapped or broken one of the plug wires inside the rubber coating. So although I couldn't see a break in any of the wires, the plugs weren't getting any juice.

As soon as I put new wires on, it was perfect. Just because the wires aren't showing visible cracks doesn't mean they're fine...how old are yours?
