Help!! 68 mustang

Rosanna · 05-04-2003, 11:49 PM

heres the deal, I have a 68 with a stock 289 under the hood. For the last couple of days it was acting like it's not getting enough fuel so i replaced the fuel pump on it. Today it ran a little bit better but still kept stalling out and not wanting to restart. I drove it another 6 blocks and it shot the # 7 Spark plug out of the hole, but not all of it. I t only shot the ceramic end out. The piece with the threads was still in the block. Does any one know what can cause this and if so how do I fix it?

Jeez thats scary! What compression are you running? Any chance of detonation blowing the plug?

Rosanna · 05-08-2003, 12:20 AM

i haven't checked the compression yet. But i did get told that if the plugs were old, which they were, then that could have been the cause.What do you mean by detonation blowing the plug? I never heard of it. This after noon I replaced the plugs and wires, and noticed fuel leaking out the sides of my carb. it isn't leaking in front or in the back, but it is leaking around the spacer between the bottom of the carb and the intake manifold.

sounds more like it was just broken...
what did the old plugs look like? black from to much fuel? or white from to lean?

also, check the fuel filter...

Rosanna · 05-08-2003, 09:52 AM

The fuel filter is new. and the plugs all 7 that were left intact are black and fouled out. with in exception of maybe 2 of them that have a clean spot on the electrod. the one that broke though there isn't anything in side the plug to tell, but the end that goes in the block wasn't that badly corroded. I agree that the plug was most likely faulty. and the compression was high enough to finish breaking it. But as of right now i can't get the dumb thing started. I believe the gaskets under the carb and on the intake manifold is blown.

Dark Knight · 05-08-2003, 10:15 AM

black is to rich... sounds like the carb might be flooding..
what carb is on it? stock? try tapping on the carb with a screw driver handle in case there is dirt in the needle valve.. might need a rebuild though..

check for spark too.. if you have one of the plugs out, stick the wire on it and rest the spark plug on a fender, then crank it over and see if there is any spark at the gap.. OR stick a crew driver in the boot, and hold it near a body part and turn it over..

did you clean the plugs when you put them back in?

Rosanna · 05-08-2003, 02:11 PM

It has a stock carb. I rebuilt it last year because it was leaking fuel around the spacer. I went ahead and bought new plugs and put those in yesterday. I didn't see any sense in just replacing 1 plug. Besides it needed new plugs anyway. I actually drive the car everyday when it is running. I also had to replace the plug wires as well, about half of them broke when I removed them to check plugs.
I bought the car last year, and so far I have rebuilt the carb, replaced the points twice, The first set of points I bought were faulty, replaced cab and rotor, changed the timing gear and chain, replace the oil pan gasket, the alternator, voltage regulator, the coil, the start selnoid, the power steering hose, Now it needs a new power steering compressor. I actually took it to a ford dealership and had them turn the distributer around ( it was 180 out) this thing is almost too much work. This does not include body work that needs to be done.

Dark Knight · 05-08-2003, 02:45 PM

yeah, older cars can be alot of work.. especially if they havent been taken care of.. you should see MY 68 though...

did the new plugs and wires help? and did it start?

Rosanna · 05-09-2003, 05:24 PM

It started ran for a few seconds, and died again. as soon as the motor heats up a little bit it trips out. it will try to start and run right up until I let off the starter or until the starter gives up. It is going out. It has been tring to die since just before last winter. I love my car but right now i really really hate the danged thing.

Sounds liek classic signs the coil is going bad, In the start position you coil gets 12 volts and in run it only get 6 volts. it sounds like when it get 12 volts it will put out enough spark to try and do somthing. Dp you have an extra coil laying around off of anything else around there?

Rosanna · 05-12-2003, 12:42 AM

no extra coils laying around. But my dad says that the carb leaking fuel may be because of something blocking the float and needle. i don't know. i almost wish i could sell the danged thang. but no one really wants to buy it becase of the body damage. If I do the work my self and get the parts from mustang's unlimited, it will still cost me almost $ 6000.00 for the parts.

KrivoK · 05-12-2003, 07:25 AM

$6,000!!! Would you be replacing every single piece of body on the car? Just seems kind of steep from what I am looking at.

Dark Knight · 05-12-2003, 08:02 AM

the dirt in the carb is why I said tap on it with a screw driver handle..

sometimes that will knock a piece of dirt loose..

as for body parts... you can always look for local mustang shows..
you can find hoods and stuff for pretty cheap.. I have a hood in pretty good shape that I'm going to get rid of but shipping would be alot...

Rosanna · 05-15-2003, 10:51 PM

it is steep, but that 's inside and out and no the car isn't worth the trouble most of the time.

KrivoK · 05-16-2003, 07:13 AM

It's a mustang, it's always worth the trouble. At least in my eyes. I think there's a coule other people that might agree with that. Just take a deep breath, count to ten and start into it. The end result will be well worth it.

Just my two cents!

Rosanna · 05-18-2003, 01:24 AM

most of the time i agree however i get really frustrated with that thing.
