Fact is that my 91 Z has been sitting in garage for a few years without running. One of those "just never got around to it" things. Paying for it now.
Anyways, new battery, engine turns and runs briefly with starter fluid. great.
I knew gas was bad so I removed sending unit/pump (very corroded), sucked out all old stuff, replaced pump/unit with new. Also replaced filter and blew out fuel line with air. Added new gas.
Still no start. I have fuel pressure at rail. You think rail and/or injectors are clogged? That's my guess. Can they be cleaned or do I replace injectors?
Also, i see many types/ratings of injectors. Any help with this? My plan for now is to keep it stock.
Thanks!

 

Do you have spark? I'd check there first.


Could also be moisture accumulated in the distributor cap, especially when you say it's sat for a long time could be a problem. Take the cap off, lightly spray some WD-40 in the cap, shake out the excess, then put the cap back on, and see if it at least tries to start.

 

I'm guessing it has spark because it wants to run using starter fluid. Perhaps a weak spark from what you said. I could check that but still thinking injectors. Didn't know if they get clogged from sitting.

 

If the car was sitting for a few years there is a good chance that the injectors are clogged. It will cost just as much have them cleaned as it would to get a replacement set. If you're interested give us a call and we'll be happy to help you. Make sure that your entire fuel system is cleaned out...tank as well

 

I really don't have a problem replacing them, other than the difficulty in doing it. I want to make sure I get the right ones, as I see there are many types.

 

you need the 19lb bosch

 

I ordered a set through the ebay site. Also going to change out EGR and Fuel regulator since I'm that far into it. Plenum gasket too.
