soo to make a long story short my truck wont start and i had to get it towed home. no warning signs nothing?! i just went to start it and it tried turning over but wouldnt start?!?

any input would be greatly appreciated!

oh and the plugs and wires were just replaced less then 5k miles ago.

 

is it getting spark? fuel? if neither, id suspect the asd (auto shut down) relay its in the underhood fuse box. swap it with the a/c clutch relay, or fuel pump relay.
let me know what you find.

 

tried swapping the relays and still wont start... the starter turns but the motor doesnt fire up

 

is the starter turning ?
try mashing the gas pedal some. that help any ? (bypasses iac)
when you first turn the ignition on, can you hear the fuel pump whine ?
with a rag to shield your eyes and clean up the mess, and while not smoking, press the valve stem in the fuel rail test port. does gas squirt out ? (like 49 psi worth)
12 volts at the coil ?
spark at the plugs ?

 

try a spark test, take a plug wire off the spark plug(preferably number 1 drivers side very front closest to rad.), put a screw driver in the boot, where the spark plug would go, and hold it about 1/8" away from a ground (i use the master cyl. for the brakes. or even the steel brake line), and have someone try to start it, if dont see a spark, check the coil. im not sure how to test it, its been like 3 years since ive tested one, but if you take it to your auto parts store they should be able to test it there.

however if you have a spark, check for fuel.

 

ya the starter is turning.

and i just went out and listened and i dont hear the fuel pump turn on?! should it be pretty noticeable cuz i dont hear it when i turn the key.

 

no...it will not always be noticeable. i cant here mine when i try to...and it fires every time i turn the key.

you really need to test for spark. not unusual for a coil to go bad.

if you are scared to use the screwdriver then get an ignition tester...about $15

 

a spark test is a must, and its the first thing i always do. its the simplest test you can do really.

 

ok its too dark out to do that now so after work ill try it and let you guys know.

thanks for the help!

 

its never to dark to do a spark test...darker is better...you know if you have a spark
