Hi Everyone,

Could you help me with my car?
2011 Audi A3 TDI

I bought the car from repo auction and the previous owner had put gasoline in the tank. So my friend which is not a diesel expert (but he works as a mechanic at Lexus dealership) replaced the HPFP, 2 glow plugs, 1 fuel injection and the fuel filter. The car only crank and does not start. When I put diesel spray on the intake then the car start. The car also has a p0087 code, glow plug lid on the cluster and can't pass 3000 rpm. If you have time please help.
Thank you.

Fuel pressure too low.
Fuel supply pipe blockage.
Fuel pressure sensor harness open circuit or shorted.
Fuel pressure sensor harness electrical circuit poor connection.
Blocked fuel filter.
Visual Inspection of Hardware (Camshaft, Cam Follower, etc).
Mechanical Deficiency of Hardware (worn or missing parts) .

Possible Solutions:
Check/Replace all faulty Wiring/Connector(s).
Check Measuring Value Blocks (MVB) for Fuel Pressure.
Fuel trim activity 0.90 - 1.15.
Output value rail pressure controller > 2 MPa.
Difference between target and actual pressure > -16.38 bar.
Check for bent/squeezed Fuel Lines.
Check Low Fuel Pressure System for Leaks.
Check Fuel Filter & Filter in Fuel Pump.
Check the Fuel Quantity supplied by the Fuel Pump (G6).
Visual Inspection of Hardware (Camshaft, Cam Follower, etc).

Special Notes:
When found in 2.0l TFSI:
Check Fuel Pressure.
Check Technical Service Bulletin (TSB) 2027458/01-11-19 (North American Region (NAR)), for an improved Fuel Pressure Sensor (G410).
Check Technical Service Bulletin (TSB) 2015153/15-11-03 (North American Region (NAR)), for a worn Intake Cam Shaft (superseded Technical Service Bulletin (TSB) 15-10-02, 15-11-01 and 15-11-02).

I think I bleed the air on Injector 1,3, and 4. I don't have a tool to reach Injector 2. I used VCDS #35 to run the fuel pump to push the air out of the injector. The car still does not start. I will update again when I buy the tool to open injector 2. What is the wrench size to open the Injector 2?
I talked to a mobile mechanic, he said it might be the timing is off after my friend installed the belt.
