Help with troubleshooting
I’m the owner of a non running supercharged AP1 looking for some guidance on next steps. The car is supercharged with a comptech kit and AEM V1 management. The previous owner had apparently driven it until April when the car would not restart and he let it sit and I absolutely trust the previous owner. I performed a compression test with 195 across the board. The car does start with starting fluid every time so I’m focusing on fuel delivery.
Things I have done/checked thanks to help from this forum:
1. Replaced fuel pressure regulator
2. Fuel pump primes and runs while cranking
3. Replaced oem injectors and stock ECU and MAP sensor
4. Added fresh fuel
5. replaced spark plugs
At present I have the stock injectors and MAP sensor in with stock ECU. The blower belt is not mounted. I can still get the car to run with starting fluid. I have the fuel pressure adapter on the way so hopefully I can get numbers by the weekend.
Anything else you guys would recommend checking? Appreciate the help thus far from the forums and I hope to contribute a solution soon.

I also forgot to mention that with the previous 1000cc injectors and AEM ECU there was a strong smell of fuel. After putting the stock components on I’m not really smelling fuel. Not sure if that means much. The stock injectors are in unknown condition since they were in a box of parts included with the car.

195 is extremely low. Probably not your starting problem, rather something to worry about next (note, if you used a Harbor Freight compression tester, thats yur problum rite thur! Reads notoriously low, especially at higher pressures).
Instead of throwing parts at it, try troubleshooting it. The starting fluid was an awesome example of this. You know it's fuel delivery. So measure fuel pressure. Remove an injector, but leave it plugged in,see if you can get it to spray into a clear plastic bottle. Visually inspect spray pattern.
Guessing either extremely low fuel pressure or injectors aren't firing.

Looking through the forums I can’t seem to find a consensus on items needed to measure fuel pressure. I got the adapter from Honda but am having trouble finding a gauge to fit into the other end. Any suggestions?

Go to Autozone, rent fuel pressure gauge.
