Starting Problem 1993 300ZX (non turbo) by corvette8

My daughter has a 93 300ZX, and we are experiencing a
problem every now and then with it starting. At times
when she goes to start it, it stalls and
dies....almost
like it is sucking for air or gas. Then it starts
normally on the second try.
 
On the road it drives perfectly, even to speeds of 85
mph. This problem does not happen on every new start,
but perhaps every 4th time. Then there are times that
it will do this 2 or 3 times in a row.
 
I have changed the fuel filter thinking the fuel flow
was restricted. I have changed the spark plugs,
thinking that I may have a fowled plug or bad plug.
The fuel pump and fuel pressure regulator check out OK
as well.
 
Not knowing a lot about the temprement of these cars,
I am lost on this starting problem. Can you give me
any insight as to what I should look at? Any info
would be great! I am even thinking it could be a
computer board/chip problem as well.

The car really needs tires bad, and when I took it to my local shop today they explained to me that there is a wheel lock on the tires. I called the owner and he no longer has it. The tires on this car are bald and I can't drive it until I find a way to get this lock off. Does anyone out there have any ideas. This sucks. I want to drive my new baby. The wheels on it are call progressive and I have a picture of the lock I took today.
 
Someone please help a lady in need.

If it's those locks that have a desigh that you have to have the matching design to get them off they are a joke . I get them off for people all the time. Get a socket about the size of the lock. I have more luck with a deep socket but I have done it with the regular socket. The deep socket will flex more to geab the lock. Put it on the lock wack it a couple of times with a hammer so itr grabs the lock and off it comes. My system has never failed me.
                      GOOD LUCK

86 300zx Aic conditioner by steve86zx

I have just bought a 86 zx. The AC does not come on at all. I have worked on many manual damper AC units but this one is different. The blower does not come on, however It does run if a jumper is put in to the battery. Same with the compressor. It runs if jumped and the lines get cold. I am assuming I have the vacuum problem mentioned in other posts because all I get is hot air from the defroster. Any help with getting the blower to start??? The fuses are all good. Any other suggestions?

Does anyone know if Infiniti '94 Q45 hubs are interchangable with Z32 hubs?

there may be a switch on your brake pedal assembly that your brake pedal hits when it is not engaged and the pedal may not be hitting this switch when it is dissengaged.

I had a simlar problem. Started off like yours and got worse over a year or so. Turned out to be a bad connection on the mass air flow sensor.

i have recently bought my zx with very few problems. as of late it has started to back fire alot when i give it gas. i can feel that it wants to go and when it slowly get to about 3 grand rpm it takes off with the odd cough but at low revs and when the car has warmed up its a real mess. you can be doing 80kmph and floor it and it goes nowhere and starts to back fire. its alright in idel, main problem is taking off and at low rpm. i have checked the injectors, dizzy and spark plugs but i really have no idea. any help would be great.
