My 1983 280z non turbo requires me to pump the gas pedal while cranking the ignition to get it to start... I know its fuel injected... when it is running it doesnt stall or sputter the response time is also go. oil presser is good also.. this is my first Z please helps Thanks in Advance.

 

I usually just pump very slightly to get mine running then slowly push the pedal more and more until it idles the way i want it too

 

Mine's kind of the same too. Usually I don't need to but sometimes I have to tap the pedal ever so slightly when starting it. As long as it runs normal, I'd say it's probably fine. I mean they're pretty old cars after all there's bound to be a few tricks here and there

 

Welcome to ZDriver!

Could you give a lil more background on the prob?
When did it start?
Suddenly or slowly got worse?
What have you checked?
Have you done a basic tune up?

 

Um... Let me think....(ugh it hurts!)

Fuel Filter, change it. Air filter...same thing. Change it. Doesn't have to be a K&N, just change it.

CHTS plug... (The little thingy between cylinder 5 and 6 below the spark plugs... toward the firewall. Clean the connections.

Of course, a general tune up goes a long way. Try that, see what happens.

 

the problem has been constant since i got the car i have a hunch its the thermo time valve...? the temp guage on the digital dash also doesnt work

 

Probably should check out the temperature sensor before anything else if your temp gauge doesnt work,

 

^ Yeah I would check that too. I learned the hard way, when I lost a heater hose on the freeway with my T-top. I warped and cracked my cylinder head, because of the gauge not working.

All aside, my Z runs great, just is hard to start also. These cars are notorious for having cold start issues. I really haven't had a Z, which didn't give me problems. When trying to start it. It is just a process of elimination. Welcome to the world of 280zx's. lol Good luck man.

 

I just realized no one has said this yet but.. Cold Start Valve?
