Starting and Idle Problems Ugh!

[Jackpine]

Have you tried starting the truck with your second key? (Assuming you have one). This might rule out a defect in the key itself.

Really does sound like some other problem though, possibly related to the remote starter. Is this a device you recently installed? Is it something that could be temporarily "uninstalled"?

I don't know what make your remote starter is. Is it one of those that requires a 2nd key? That's what I have and one time I had been on rough roads and the key got relocated away from the ignition recognizer. But maybe Jack has a point about the rs unit being "faulty". Try disconecting it and then see what happens. Here is one for you sometimes my truck will mysteriously start on its own. So everytime its parked in the garage I have to disable it with the remote and that cured that problem.

Well heres this

1. The remote starter is a viper- i put it in myself

2. The remote starter has a security bypass module that you program to bypass the security. (no key inside it) It would not work intermitent - it either works or it doesn't

3. Also this unit is not connected to the security of the car- so when using the vehicle key you are not going through the remote start at all. Because there are no wires that are cut that make it go through the remote system. So in essence it is pretty much disabled while starting the vehicle with the actual key.

4. F150online people have the same issue- you start the car in the morning run to the store- hop out and come back and it wont start until you try it 3 different times. Some say PCM flash- some say fuel pump- some say bad check value- some say injector..

5. As soon as its cranking- the truck feels like its trying to find the right cylinder and it feels like it lost power to try to keep running. Then the third time it sounds totally different and actually fires up.

6. Could be a flooded engine or something like that.

7. Or maybe i didnt wait on the "RUN" to prime the fuel pump enough before cranking it.

Either way its intermitent so taking it to the dealer is going to be hell...

PLus now my third brake light is leaking so im gonna have to take it in for that.

Plus my idle go erratic intermitent and also while driving sometimes i get a huge hesitation and wants to die and then 5 sec later it comes back to life- what gives???

The idle and starting and hesitation all happened before the remote starter...

Could it be my gryphon??????? I bought the edge used and then converted to gryphon???? do these go bad?????

[Jackpine]

Anything CAN go bad, but once the Gryphon has programmed the PCM, it's just a monitor. There's nothing it can do to the truck at all, just sitting there on the dash, except to make it look purty.

Have you gone to diagnostics to see if there are any codes?

Since you have a 2006, is the truck still under warranty?

Ok....

Haven't tried running codes

I think my factory warrenty is up june 09 but just in case i have extended till 100k miles.

The more n more i think about it- Im leading to PCM....

Cuz for one its random and two its like the PCM is getting confused what to tell the sensors or injectors to do and starts messing up and then clears itself right away. The only thing that controls the electronics is the PCM...

Willing to bet on "fuel pump"

Hard to start. Takes 2 or 3 times. Not imediately locking in priming pressure.(Check valve)also I think located in pump.

Just maybe the pcm?

Dies or rough idle at intersections? Not maintaining correct idle pressure. Could be a regulator also.

As far as injectors? Who knows.
