99 F150 WON"T START NEED HELP!!!

[jboatman333]

So i went out side to start my truck today and when i go to turn the key I get a very loud noise, kinda sounds like a jack hammer or imact wrench going off under my hood. Also I notice when I turn the key to the sencond position on the ignition all my gauges go all the way foward and hold a second then drop back down, I pretty sure the truck never did this before AND the Service engine light is stays on.
I am really hoping this problem is starter related but I am just not sure. If anyone has any suggestions I could sure use some help!!!

Eagerly awaiting a response,

Sounds like your starter solenoid is hooking up.

Will it run?
There were problems with the intake manifold gasket on V6 equipped f150's and e150's between '97 and '99. Coolant could seep into the cylinder, ok if its not a lot and the motor is running, but downright deadly if it happens at startup. My '97 did it, but fortunately it kind of locked up while it was starting. I messed up the starter (it worked but sounded terrible), but was eventually able to get it started only to find that I had bent the rod on #1 cylinder just enough to have it sound like a jack hammer when it was running. I have heard of people actually snapping the rod as well and in those cases the jack hammer noise is from the piece of the rod still attached to the crank banging in the inside if the block.
If you have been loosing coolant for no apparent reason, thats one of the first signs.

Either way, you are probably looking at a rebuild.

If your battery becomes disconnected for any period of time, the guages will all go all the way forward the next time you turn the key. I'd bed you've got an electrical problem.

you have a bad battery. replace it and all will be ok.

You Could Have A Bad Battery Or You Could Have A Parisitic Draw. The Gauge Thing Is Normal The Instrument Cluster Is Doing A Self Check

It's my understanding the lower intake gaskets commonly failed on 97 - 98 4.2's and cause the leak. The 99 up 4.2's are safe and dont hydrolock.

My 97 had that problem. It did break the rod. We had to rebuild the motor. My gauges usually hold for about a split second then go back down. Also if you got an intake manifold gasket leak, like I had, you probably have antifreeze and water in one of the cylinders and well as we all know that wont compress.
