Tohatsu 40 TLDI Won't start I let it sit for one year now it wont start

[Phol]

now replaced fuel and checked
1.air pressure = 80 psi
2.fuel pressure = 50 psi
3. spark plugs = ok
It is also is spitting out gas from screened in air intake after I try & start it
Thank you for your help!!

If by 80psi air you mean compression, that sounds a bit on the low side. Some ideas:
- Put a shot of oil into each spark plug hole then try again. If the cylinders are dry, the oil will increase compression and might do the trick. Hopefully nothing rusted from sitting.

- If you've got fuel coming out the intake, then there's reasonable odds it's flooded. Open the throttle next time you try to start it, just be ready to pull back the moment it fires.

- If that fails, give it a shot of starting fluid. If it runs for a short time on what you spray in then stalls, then you have a fueling problem. If it won't run at all with starting fluid, then you've likely got a mechanical or spark problem. Your picture appears to show a good spark, so in that case I would start looking at mechanical.

By 80psi, I think he may mean the "low" pressure air injection the fuel system uses.

I just bought an '03 40hp Nissan TLDI and am attempting to start it. I has sat for 16 months. I'm still working through my tests. No luck yet.

If you didn't stabilize the fuel, you probably have a mess. How much of a gap does the spark jump.

Wow that doesn't look good at all! Hopefully it works better now.
