Default 1991 D21 cranks but doesn't fire...HELP!!

I own a 1991 two wheel drive Nissan hardbody. Just recently I was hauling my little fishing boat home and when I finished unloading it I got in my truck to pull up in the front of the driveway and that's when this whole fiasco began. I turned the key and the damn thing wouldn't start. I've been trying to figure it out for the last well almost three days. The engine cranks over, I have switched out the distributor, cap and rotor, coil, ignition switch, fusible links, plug wires(I am getting spark on all four cylinders. The battery... it's got a full charge... It just won't fire up. When I turn the key it seems like the starters turning faster adorable and there's not as much pressure/combustion as it cranks. The the plugs are also cakes with gas after I do attempt to start it when it doesn't fire. Any and all help would be greatly appreciated cuz I'm stuck. Thanks, cweklund

Meant starter seems to be turning faster than normal.

Compression test next.



Getting any codes? They are fun to read (via LED blinks) pre-OBD-II.

Compression test first.


Unfortunately, you've also "thrown" parts at the problem....can complicate real troubleshooting....

Ok thanks guys, will do compression test next and how do you retrieve the codes? Also I was researching online and some where bringing up ignition control module and a loose timing chain. Any thoughts? Thanks again, cweklund

It could be a stuck valve or something. I'm not sure if the KA can is so close it could have overlap if the timing chain is stretched.



There is a trick with a little oil in the cylinder to see if it makes pressure. Look up how to properly do that. Don't want too much oil as oil doesn't compress well and can cause all sorts of problems. I've never don't it.

Codes won’t help you if there’s no compression. I don’t recall seeing one with NO compression at all. Makes me wonder about the compression tester. Cover the spark plug hole with your thumb and see if you can feel compression build while somebody is cranking it.
