Car wont start

[z_boi]

Ok, this has happened b4. I drove home. park the car and then it jus doesnt start up when i go out to start it. there fuel and it cranks, but no spark. Last time this happened. i didnt fix it. i was jus tryin to test connections and see if i was getter power to things. then i found water in my fuseble links. I dried it up and replaced one of the wires. then tested again and it had power to the coil. then i started it and it started up.

so its happening again. the fuseble link is dry. wires are good. but i dont have power to the coil. wat could it be?

anybody?

Sounds to me as though you are a prime canidate for learning about basic engine tune-ups and such!!! You have to understand that the question you pose is sooooooooo general that it's just impossible to provide you a simple answer. But for starters.........think about why it didn't start before. It was electrical wasn't it? Well, it's likely a similar problem if you have no spark. You just have to have a basic knowledge of the car's systems and go through the process of elimination. Just like the rest of us who have learned the hard way. A little research and some reading on the subject is a good way to start. I'm sure this is not the answer you were looking for but if you take the time to learn a bit about engines and the systems that allow then to operate, you will thank yourself later on for doing so. Give it a try anyway!!! Otherwise, if it's a matter of urgencey, take it to a mechanic familiar with Z cars. Good luck!

yea. its the same problem as last time. but i dunnoe wat it is. i never fixed it. It just started workin again. I noe that its in the primary part of the ignition system. (something b4 the coil) not sure wat it is. Im thinkin its a relay or somthing. im jus not sure. which one and where they are. Im not sure how i would check them and where too begin lookin.

I noe basic tune up. i work on my car my self a lot. i jus dont noe the efi and electical too well.

What is the car ? Injected or not? what if anything have you done ? It helps to know what ignition that you are using , and so forth. We are willing to help but neend help from you. No spark , is the ignition switch good? Is there power to the coil ?

77 280z. wit stock efi and ignition system. Im gettin no power to the coil. i tested it with a tester light.

You might try checking the ignition relay-right kick panel below the dash:

tanks for the picture. i was tryin to figure out where to check for the relays with my books but theres jus wiring diagrams.

ok, heres the weird part. I was messin with the little black box next to the coil. the one that runs to the dissy. i had a test light hooked up and the tester was clamped to the green wire. then as i was pulling it off, i accidentally touched the pen to ground. then the car some how cranked on its own. (had key in on position) then i tried it again to see wat would happen. i jus heard a tick like a relay. so i decide to try and start it to see wat happens, and bam! she starts rite up.

wats the deal with that?

ok, so its not starting again. but i tink i kinda figured it out. im try replacing my dissy. i have one on my parts car and it worked fine when the car was running. lets see wat happens after that.
