Time for report, a little bit earlier

Car still has hot start problem, tested on both solutions today morning.

I think problem is more complicated coz, on cold its the same problem.

I noticed that when I arrive to my friend, car was cold and same hard start like on hot.

In ECU no errors.

Injectors:
1. 0,44
2. 0,02
3. 0,83
4. 0,22

Camshaft timing (torsion value): 2,2 KW (max is -3 to +3)

When car starts engine works perfect, car has power and no smoke on hard acc. Battery is 2 months old.

Any ideas? My friend bought that car with that problem 2 years ago but now it very hard to start it without "easy start" spray.

Problem in tandem fuel pump. Try to change fuel filter. If problem stays, check tandem, backpressure

Full service done in October with oils, filters and a new battery.

Then check backpressure and tandem

My friend ordered second hand tandem.
I report after fitting.

After fitting second hand tandem car starts better than new!
