I ski is fuel injected and my engine is 787 compression is 150 on both

I just looked at it battery was dead test the battery was no good put a new battery in and compression is reading 150 on both but when I started it fired died after a second have to give barely no gas to keep it running but still does not stay running can’t keep it running you know what the issue is checked injectors are good and I’m getting spark also getting fuel
Check your fuel pressure. 56-58 pounds is what I generally see on my gauge. There are many other things to check. I'm trying to get one running now. I spent about 10 hours troubleshooting this one so far and I have parts I can swap which is a big help. It's a tough one. Hope yours is easier.
How do you check fuel pressure
I suggest downloading the manual for the year/model of your ski. You'll need a fuel pressure tester. Some people buy a kit. You might be able to find one that will work. If you have a multi-meter you can begin troubleshooting components. You need a few tools to work on these skis.
Ok yes I have the manual
You're gonna have to figure out what the problem is. Start with fuel pressure. Hopefully that is your problem If not, then go to plug Number 4 on the ECM. find the component testing in the manual and print those pages out. Get comfortable and check the pins with a mulit meter and check the sensors, Throttle Postion, Air Pressure, Air Temperature, Crankshaft position, fuel injectors, etc...
