Wont start and need help

I have a 68 GTO that I am usually bugging people about however my primary vehicle is dead and I need help ASAP
Vehicl is 97 F150 4.2 auto trans. When I turn the key, all I hear is a "chunk" its trying to turn but wont. I removed the starter and had it bench tested and it was fine. I put a brand new heavy duty battery in her, still the "chunk". I was able to rotate the pulley bolt with a wrench about a 1/4 turn in each direction (thats all the room I had and was unsure if it was clo9ckwise or counterclockwise from the drivers seat, being which way it tuns.)
Its my only daily driver since the GTO has no tranny and I need to get to work on Friday and to a parts store today. PLEASE HELP.

Thanks,
Simon

Bad battery cable is the next probable culprit. They can look very good on the outside and still have corrosion on the inside @ the connectors. Check both postive and ground cables.

Good idea Willies. I cant remember for sure but a while ago on my t-brid (when i was still driving it) i think the starter regulator thing went bad, it did the same thing.

Could it be that the starter spun when bench testing because it was under no load but when I put it back in it just did not have enough ooomph to turn the engine over?

Starter will test fine with no load sometimes. Use a voltmeter across the battery and see if there is any voltage drop when you try to crank the engine. If there is quite as bit and starter does not work chances are it is bad. Does the starter have the solenoid on it. If so if it has the spade terminal connector on it for the small wire it may have a bad connection. Ford was notorious for that connection. Weather and elements killed the connection. They went through 3-4 upgrades before they got the solenoid correct. If no or very little drop, check for clean terminals or bad cables connections.

i know first hand the ford 4.2 has a terrible reputation for head gaskets going and when they go the antifreeze leaks into the cylinder over night and fills it up and when you go to start it in the morning thats all you'll get.
sorry to say it sounds like you have a bad head gasket

Badknuckles is right. It could have hydraulic'd on you. We had an alcohol open wheel modified do that one time. After that we put a fuel shutoff switch within my reach and I always shut the fuel off so there was no chance of it leaking into the cylinders. But I got the same sound from the starter. If you cannot turn it over by hand drain the oil and see what is in it. Could be antifreeze if the head gasket went.
