i have the 2.8l mpfi and i am having issues with it blowing the fuel relay... it will start the first time on the relay but after i turn it off it won't fire again. Any suggestions?

 

try replaceing the relay should be about 20 bux or so.

 

Check the wiring at the bottom of the connector. If it's like mine was, the wires are shorting together and causing headaches. Go to a place that sells alarm or security systems for cars and see if you can't pick up a relay and connector. That's what I currently have mine running on (well, when the harness is installed, anyways) along with the fan relay (dual relay block, using both relays in the block).

It's either that or the fuel pump is drawing too much current through the relay. Have the current draw checked if you can't do it yourself.
