I have a problem when starting my truck it starts fine but shuts right off I already change the tps back in the summer fine till this morning . thanks for the help.

 

did you check the IAC? should be on the back of the throttle body held on by a couple of torx screws, sounds to me like its dirty/bad for $30(well last time i had to get one but its been a while) you might as well just replace it

 

Did your truck sit for a while before restarting? Do you need to goose the throttle to keep it from dying? If so, what he^ said, bad IAC. BTW, it's around $70 now. Or... how old is your battery? Does the idle stumble before catching? Strange things have been known to happen to our Ds because of a subpar battery. Just sayin'.

 

Do you have the gray key head? It sounds like the theft system is shutting you down.

 

^ That's good! ^

 

Gray key! Why didn't I think of that?

 

gray key? mine is black, and so are all of the ones i have seen on 1st gen trucks . . .

 

Some Ds can be fitted with demobilizers from the factory. Hence the gray key, it has a RFID in it to transmit a code for the engine to turn over. Without it, no start.

 

Still sounds like the theft system fuel shut off, don't you think??

 

hmmm i learned something new today,

i still think you should try the fuel pump relay
