300zx Turns over but no start

Wassup y'all?

I have have a 90 300zx na. The car turns over but does not start.

I have replaced the PTU, the CAS, checked the ECU all good, fuel pump kicks in, fuses are good, relays are good, coils are sparking. Still can't find the problem.

I have posted a video on youtube recently, http://youtu.be/PgQ0XOAwv7M , lol i even tried clutch starting it.

SOMEONE HELPPP lol

Sounds like it's flooded losing compression. How did the plugs look? Do you have any codes? it sounds like it wants to start. Most nissans if theyre flooded you can hold your foot to the floor while starting. Don't let off til it actually starts. It's called clear flood mode. It will turn the fuel injectors off while it starts. This may help since when you gas it it seems to try to fire.

No codes but spark plugs look done. Should I replace them and try deflooding it? Also the spark plugs do smell like straight gasoline. I don't think that's normal.

If theyve got any fuel on them I'd say replace them with the correct NGKs and try flood mode. If you're still getting fuel on them your injectors could be sticking. Common issue if the car sits for awhile.

Did you take the CAS out and turn it by hand and watch make sure plugs are sparking when they should?

I had this same exact problem a few months back.... try cleaning the connectors for your coolant temp sensor. If thay works, replace it! Quick and cheap
