My Z just wont start.

I drove my Z to the Dr. and parked it. When i got back 1/2 hour later it turned over and ran rough then died. Now it cranks but nothing else. I checked spark it is all good. The fuel line has good pessure when I squeze them. Any idease. I am thinking I might have jumped a tooth. The motor does have 382k on it. Any other ideas would be great. It is a 78 280Z. Oh yea all the guages were perfect before I shut it down. Oil was at 45 lbs. Alt at 16 volts. and it was idaling perfectly. I was hoping maybe Vapor lock. I have never experienced vapor lock before. I drove her last weekend about 120 miles on a nice mountain road. She ran fine. When I fired her up today she started on the first attempt like always.
Any help is appreciated.
Thanks
Shane

pretty big problem, hard to pinpoint via the internet... but you could try listening to make sure your injectors are functioning.. take a big flathead screwdriver, place the head of it somewhere on the base of the injector, and stick your ear right onto the butt of the handle. it should click.. repeatedly as you turn the engine over. each one. (duh) i dont know where you could go form here, but its an idea, and i figgered it might help...

a more precise check of fuel pressure would be good too..

does the engine even TRY to start ever?

its not too hard to remove the valve cover, so take it off and inspect the timing chain. can't hurt. if all this stuff checks out, id imagine that its probly a timing problem that you would need a timing light to check, or dissassemble the front of the engine and check the chain the hard way.

wouldnt it be nice to go to autozone and see one of those ECU diagnosticators that somehow worked on an old-skool "dot-soon?"

I figured it out I had a wire come lose on the fuel pupm and the injector relay at the same time. Which I find strange cause I was driving it and parked it just before it died.
