I have a 2000 Durango - 5.2L V8 - As of this morning it will crank, but will not fire. I hear the fuel pump running and smell gasoline. I have produced a spark to ground from one of the spark plug wires. No codes come up on the Odometer.
Any suggestions on why it will not fire? Many Thanks, Mark

 

Well, you could try to spraying some fuel while trying to crank it into the TB to see if that may be the issue.

Fuel pump is in the tank and the whole thing is one unit. But we have already talked about checking the fuel pressure on the fuel rail port.

 

Thanks to all feedback. Replaced totally fouled plugs and old wires. For good measure - added fuel injector cleaner to gas in tank. Fires right up and runs like a top!!
Good luck and thanks again... Mark

 

Glad you got it going. if you replaced the plugs and wires it is probably time to replace the cap and rotor.. When you goto get them make sure you get the brass or copper terminals and NOT the cheap ones.

 

I'm glad you found your fix. Theres lots of information on here on tune up's and so forth.
