Fuel pump pressure is around 60 psi so that's good and there is spark. How about you injectors/fuel pressure regulator. Know as (spider) injector. I had to replace my unit 3 times already. Other then that it hast to be a bad sensor, like crank,cam,oil,coolent sensor.,knock. Just one of those is faulty equals no start. Have you checked the ignition timing?

So you got it running now. What was the problem? Something simple? I am happy to hear that. Finally

Update : After next spark plugs change,engine start,but for a few minutes
If I have a rich mixture, engine stops and wont start, plugs are black / carbon and wet from gas.. What its mean.. bad pressure or IAC ? Idle is very bad

Fine, I have a new pressure regulator and next fuel pump.. but When I turn the ignition key, the in-tank electric pump starts up, but the pump relay starts to click-clack very fast. Within few seconds I switch the ignition off and back on and pump relay starts up again instantly – what should not happen, of course. Relay is brand-new, as well as the pump, fuses work well. OBD does not work any more either. This has happened once already, but it stopped of its own accord. Hence, the pump does not pressurize to the original pressure value of 61Psi and I do not know where to look for the malfunction.
Thank to all for help..
