Mustang knocking!??


My mustang gets NO driving time at all, i start it an let it run every now an then at tops for 20min. today i rolled it outta my garage, started it up and it was running for about 10min then i heard a loud knock. i ran over to check it out an the check engine was blinking, an it was knocking bad. i go to start it up again an its barely running & VERY quiet. then i tryied again an it wouldnt start (sounds flooded). also when i turn the key it usualy makes a high pitched sound, the sound when i turn the key is very deep an weak. can anyone shed some light on this??? i'm stumped

for starters check the oil level......if i remember correctly you have a 4.6 stang? if its low on oil the lifters won't pump up correctly.

Gixxer- oil pressure is regular

Snakebite- I did the oil not to long ago an bought a fram tough gaurd an its for the car no doubt, the car will not start but wants to so idk if its going to knock still an cant test it until it starts up lol.

Droptopfox- Yes, it turned into a low pitch whining whenever i turn the key. whats the best way to check the fuel pressure?

letting a car sit is the worst thing you can do.

i would run a scanner on it since it's obd2 you should be able to figure it out pretty easy.

probably start driving it and it will go away too

last i heard it was knocking & the check engine light was blinking so i turned it off...it never started again. everytime i goto start it the thng it wont, but it wants to.

Droptop- i kno your all about ford, but my breaks popped just last week, now its pulling this bullshit, but on the other hand by the time i get my liscence back at this rate everything should be replaced by then lol.

88mustangt- i would do the 5.0 but im buying the new 5.0 very soon, so i'm gna keep this a 4.6. like i said at the rate this thing is breaking i'll be brand new.

You can still run the codes even if the engine won't start. Got a scanner handy?

If could have been knocking because it was stalling out? Is that when you heard it and the engine wouldn't fire anymore?

If you think the engine is flooded, floor the gas pedal to the ground and crank it. Pressing to wot tells the eec to turn off the injectors to allow starting the engine. If it does start, be ready to shut it off. If it is flooded. It could be a bad idle air controller, throttle position sensor or ect.

Code scanner could help narrow things down.

Funny you say that, i thought the same exact thing so i took my tank out to drain it an there was nothing in it. my gas gauge was stuck on 1/2 tank. i did some wiring an problem solved. im kinda pissed at myself for i runnig my car out of gas, but there was no way of kncowing...... at least there's no real problem.

Mustang5l5- you are 100% correct, i wish i came on the forum before i started taking out my tank lol
