Spark on all wires? Then you might be right 88rustyred, might be timing, but it's starting to sound fuel to me.

 

Yes its the 4.9. I was wondering about the timing but I doubted it could be that. The weird thing is that after it starts up finally, if it starts up, it runs completely fine.

 

Back to ign module and coil tests ?

 

do you have dual tanks by any chance......

 

Yes I do, forgot to include that

 

Puddy, I forgot about those dual tank dilemas (have bronco,now only one tank). I'm gonna let you take it from here. Good luck ya'll.

 

Thank you for all the help you gave anyways!

 

there was a tech bulletin about them, gonna bet thats it. or the switch its self. (i have a single tank and when i disconnect that plug it will just crank over and over, great lil cheap security)

 

A tech bulletin about what? What switch?

 

Courtesy of Subford for the fuel selector switch.

if its not that then its the selector on the frame.
have you tried the other tank??

 

Woke up today and tried the truck and nothing. Went to auto zone and picked up some spark plugs and spark wires, put them in and still nothing. Tried the rear tank but I didn't even hear it prime. Put it back to front tank, turned key to accessories for 10 seconds because I hear it does something lol, then after about 30 seconds of cranking it starts up. Take it to orielly to get an obd scan, comes up with the egr valve is closed, coolant sensor temp is low or something like that, and a secondary fuel pump valve or something failure. Now the truck won't start again and I have no clue what's wrong.

 

Anyone else? Please and thank you!

 

Well, ya.

Puddy gave you some good advise.
The in-dash tank selector switch.
When they go south, nothin' works.
They're inexpensive and easy to replace too.

So that may still be the cause even though it sometimes starts after a while, and runs completely fine after it starts?

 

Based on these symptoms, it sounds like the in-dash switch is "failing" and not totally "failed".....ie. intermittant connections.

"So that may still be the cause even though it sometimes starts after a while, and runs completely fine after it starts?"
Yep !!
