hard to start and cannot rev
i owned volvo 940 turbo which was manufactured on 1997. Recently, i change fuel pump, fuel filter, fuel regulator, air mass, plug, cable plug, oxygen sensor, and crank sensor.
so the problem is that my volvo hard to start sometimes i have to put fuel at the fuel regulator to start up. what is the problem?
second problem, once i can start the start the car cannot rev. i will upload the video soon and give the link to you so you will understand what i mean.

did this car have these symptoms before you changed all that stuff? btw, what is 'plug, cable plug' ?
940's weren't sold in the US after 1995, so presumably you're somewhere else. if you're somewhere else, you may have a different engine than the US model 940's most of us are familiar with, B230F or B230FT, with Bosch LH 2.4 (or Regina) injection and ignition.
a failed MAF (mass airflow meter) can cause 'hard to rev' symptoms. but it also should throw a diagnostic code with the check engine light, at least in US models.
