Ok, i removed the engine, slapped an 81 280ZX 5 speed on there and put it back in...
Ive had problems ever since.

My charging stuff went out in the process of putting it back in, somehow...

i have a new starter, a new alternator, a new voltage regulator, new clutch and slave cylinders, new spark plugs and wires, new clutch....

I was planning on taking the car to an electrical shop to get it all fixed up so i wouldnt have to worry about it anymore.. it was running then and shifting fine.

I took it out and around my block the nigth before i was going to take it to the electric guys. It didnt run great, but it has been sitting and i didnt expect it to be perfect. But i had full range on the clutch and it shifted fine.

next morning i hop in and start her up. and she wont shift. not when it is running.
when the engine is off it shifts fine, and if you try to start it in gear it jerks and all that....
Ok, i just went outside and tried to put it in gear, push the clutch pedal in, and it still pulled, just a very little bit.

My big problem is, that it wont run now, it will just barely start up, then shut down, and if i even tap the gas it dies, i am going to go outside in a minute and change the main fuel filter.
Any ideas?

So, while the car is in neutral and you try to start it, what happens? (oh, get a battery charger and make sure the battery has a full charge) By all means DO NOT TRY TO JUMP START THE CAR OR LET THE ALTERNATOR CHARGE A DEAD BATTERY!! Are you sure you properly bled the clutch lines? Got the clutch pedal adjusted correctly? Got any fluid leaking from the clutch master or slave cylinder? Got a factory service manual? (if the battery is very low, the efi stuff won't work) Try to adjust the tps, ect....?

Clutch hydraulics....

Sounds like one likely suspect. It should still idle in neutral tho. Check the stroke of the slave cylinder. Probably need to rebleed 'er. I went thru **** bleading mine cause it kept sucking air in through the slave cyl seal. New slave cyl unit fixed 'er right up.

must be nother prob about running. Search on Johnb510 for lots of great tips on troubleshooting fi sys.

Good luck!

Hydraulics...

Sounds like hydraulics, but did you keep the same clutch throwout collar that was in the fivespeed, and keep the same pressurelate? L28 to L28 shouldn't pose that problem, but you never know. Why did you pull the engine at all? this is not required to do a tranny swap. This begs the question, did you swap the entire engine/tranny from the ZX into your Z? If you did, what electrics did you use, and what alternator did you use?
Need a bit more specific information to really help other than grasping at straws---will check back later sto see what's up...

actually

Well, there is no spring on the clutch pedal and it feels great and definetly has pressure. i am going to check to see if it moves back after a couple of seconds of engaging it to see if it it the problem...

Also, the reason i pulled the engine was because i WAS planning on doing a full swap, but, the engine that was "rebuilt" sucked. ( i could tell that there were some definite problems)

The running problem is due to the electric system. (dont know exactly what is wrong though....)

I think there is somehting wrong with the pressure plate, i did put the clutch plate in backwards for a while, and pulled it to fix it, the pressure plate just didnt seem... right..

anyways, i am going to go and hang out with some friends tonight

I'll get around to it...

The spring, is not the problem, i'll go install the spring... but it wont help.

I checked the hydraulic system, and it works flawlessly.

I am stumped, as are quite a few others that i have asked about it...
any ideas as to why it would be failing to run though? i charged the battery up, and it still wont start up.

i am sort of suspecting it is the EFI system.... but i dont actually know...

thanks for your suggestions guys...

Nothing more specific...

So I checked back, nothing more specific, so here goes:
Everything on the late model EFI system will pluginto and function with an early EFI ECU. I did it in my 76 for a year until I got my early non-EGR manifold ready. I ran an 82EFI intake and manifold with all the sensors hooked to the 76 ECU. Make sure you ahve all the connectors hooked to the correct place, and that they aren't all corroded. Make sure you have a good ground. You CAN use the late model internally-regulated alternator on the early car, and it will charge and run fine, but your red light will be on in the voltmeter, and you will fry the external regulator.
As for the clutch not releasing, or grinding going into gear, your pressure plate is not releasing. Again, are the components ALL from the same transmission? I.E. did you take the clutch, pressure plate, TO bearing an collar ALL from the same transmission setup? 9 times out of 10, when a problem is arising like this, and the pedal functions, the wrong collar is installed with the wrong pressure plate.
Keep at it.

found the shifting problem...

well, i removed the tranny again today. and found that my flywheel bolts were actually very loose for some reason. (Hard to find good help these days).

that is why it wasnt shifting...
it could possible be why it isnt running well... but i am doubtful and thingk that that is a separate problem.
