Reviving a 2009 st1300 San Bernidino police bike. Starting issue

[larkmachineco]

Get ready for the run down.
I bought this bike from an individual that purchased via auction. I didn't here it run, but I did turn it over and got it for 1000$

2009 st1300 101k miles. Laid down on the right hand side. Mirror and fairing cracked. No frame damage and a flat battery.

Owner said he had heard it run, but it idled real bad and couldn't fix it.

I got it home, put in a new battery and have had it one a charger ever since. I noticed some issues with the wiring when the gun lock and some lights were removed.

I checked all fuses. All good. Turned bike on, flicked the kill switch and fuel pump and FI light turned on ( no flashing). Cranked it and it started for a moment, stuttered, never revved up and eventually died. Felt like fuel starvation.
I checked each plug for spark. Had it and most came out wet. I put 4 gallons of 91 on it. Never got it to run again.

Changed map sensor and intake temp sensor with ebay take offs. Measured the temp sensor 2.8kOhm. Map sensor has power on power pins. Still no start.

Removed fuel outlet, sprayed fuel. Removed fuel injectors, they sprayed fuel. Still no start.

Sprayed starter fluid. Cranked up, revved up and flamed back a bit. (No damage).

TLDR. Runs on starter fluid, won't start or run with out it. Has pressure and injectors squirt when Removed. Seems like a too lean issue. Any thoughts.

Not battery. Last pic is included for fun. No damage was done

Thanking everyone in advance for whatever expertise I can get. I'm a newbie when it comes to st1300s, but I am a competent mechanic. Leaning on the experience of the community to help out!

Welcome to the forum.

Yeah, these old cop bikes, do have their issues. I have an '06 that I bought and was able to get it running, but it had so many other issues, I decided to do a engine swap to an '05 I picked up with a bad motor.

You can see my project: HERE!

I would suggest, getting a hold of Larry ( @Igofar ) he has a lot of experience working on these bikes, including the old cop ST1300Ps.

Thanks for the reply. Looking at your project give me anxiety!! Great job. I'm usually pretty good at troubleshooting, but the fact it runs on starter fluid and not on the injectors is baffling.
Makes me think it's a sensor causing a lean condition. Injectors are definitely squirting when out of the intakes
Is there a diagnostic software for these bikes?

ST Flambé? Usually that's the last resort. Right before the call to insurance.

I noticed some issues with the wiring when the gun lock and some lights were removed.

You should apply to the Diplomatic Service. Referring to yanking on wires and looms and hacking with side-cutting pliers as "some issues" is generous to say the least. Yeah "de-copping" a police motor isn't done with the next owner in mind.

Good luck with your restore. I hope we see a pic of it fully restored not fully involved.

Have you picked up a shop manual yet, there's a lot of troubleshooting information in there
