Fuel Injector & Fuel Pump integrity check

[quote:681580ad8a="dirk_garnett_06"]1995 Nissan Bluebird CA20(EFI) 140,000kms. Is there in any method how to check integrity of fuel injectors using dmm/portable tester? May I please know the symptoms of near-faulty fuel pump specifically for my car? I'll appreciate your thoughts.[/quote:681580ad8a]



You can check the injector's resistances-also the amount of electrical pressure going to the injector. There's other things to check but you have to remove it-to check patterns/pressure drop-

Check fuel pump pressures with and without pressure regulator and how long it hold that pressure/volume etc.
