RED SHARK 1990

Hello members i have had this problem for about a month now-with key in ignition the car would crank but will not start until the third tried.I have had the 2 fuel pump replaced last year,intake refreshed included injectors rebuilt kit-pintle and caps,seals,all hoses.All ignition electronics are newly replaced,caps,rotors,plugs etc.Could it be the fuel reg?or something like the LH brain is starting to go bad?Thanks Luan

Does this happen only when the engine is cold, or also when it is hot? Have you replaced the temp II sensor?

Hello members temp 2 was replaced new also last year,i think when it was warm-sometimes it would start right away and other times after driving and park for 2-hours and it would take a 3 crank to start the car.I remember after the intake job the car would start right away every time.

Hall sensor?

Did you check the fuel pressure as the car sits?

The Hall sensor will not cause a hard start. I think you may be thinking of the Crank Position Sensor (Above the flywheel).

Did you replace the fuel filter?

Thanks members for trying to help.The hall was replaced sensor last year ,cranks sensor was 3 months ago,and a new fuel filter also.The fuel rail on the passenger side orig looked a little bent at the check valve so i did not installed a fuel guage.I know the fuel regulator is not new on the car and as also with the fuel damper in front .Any other suggestion will be appreciated.Thanks

The check valve is back at the pump. The cap on the pass fuel rail is just a test port.
