I'm having trouble with my truck its not wanting to start but only some of the time. It seems to me that it will start fine when i have not used it in several hours then if I drive it for a while and stop and start it wont come on and if it does then it will die quickly after. Had the MPI replaced a few years ago when it did something similar and about 3 months ago it was doing this and my mech found a connector that was loose and fixed it and have not had a problem till now.


Any Ideas

 

Does it turn over on the starter and just not fire? That's what it sounds like.

Have you tested fuel pressure? That would be the first place I would start with the reputation for failures in the fuel system (spider or fuel pump).

 

Just curious....did you ever figure out your starting problem? Mine is doing the same thing....start it cold and it is fine, but make several start, shut off's and it doesnt like to start unless you floor the gas pedal....I am lost on this problem. My dad has replaced just about everything that he could think of and still no resolution!! Let me know if you find out anything I'd be glad to give anything a try at this point!!
Thanks
