hey guys...on my 98 4.6l V8, the car wont turn over...there is beeping when the key is ON coming right from where the "fuel pump shut off switch" is.
(my negative terminal was off for over a week, while i was changing the Intake Manifold gasket)
i also have a Shelby remote car starter installed, but the place that installed it said there is no module in it that wont let the car start.

any help is greatly appreciated

 

If it's a 5 X5 beeping pattern, it's coming from your airbag module and means the airbag warning lamp in the cluster is burned out. Has nothing to do with starting.

Define your fault: "No Crank" or "Cranks but No Start"

Manual or automatic tranny?

Factory anti-theft system? (has chip in key...). The 98's factory PATS system includes a starter interupt feature. If PATS-equipped, what is your THEFT light doing when you turn the key to RUN?

about the 5 x 5 beeping...ill check as soon as i get home.

the truck isnt cranking at all...i replaced the starter relay, also

automatic tranny

and it doesnt have anti theft...just a standard key

 

Have you tried jumping the starter relay? Just cause its new doesn't mean its good...

 

ya, i tried with the old one and the new one...i actually dont think my old one was bad either

thanks

 

is the sensor underneath(on the drivers side of the motor) the upper intake manifold the crank sensor?

 

Crank sensor won't keep it from cranking.

You have a starting ciruit fault.

Check fuse F21 under the hood.

i just checked them all...they seem good...

the starter was replaced less than 18 months ago but i still want to fiddle with it just to check...do i follow the positive terminal to find it?
