Sounds like your injectors are not functioning.. simply feel an injector while cranking the engine, you should be able to feel it click if it is opening.. Buy a steiscope at Harbor Freight if you do not have one.. this is a very valuable tool for only a couple of dollars..listen with it to the injectors. you will be able to hear them if they are functioning.. Then injectors have ground wires,, these are usually bundled and connected to engine at some point on the intake for grounding the injector circuts.. very rare but sometimes these wires are corroded or discnnected, If the injectors are not working check all the power going to the computer... past this.. computer problem.
What should the fuel pressure be for 1995 Isuzu Rodeo 3.2 L? Installed a new fuel pump, changed filter and only getting 32 psi. Already changed the timing belt spark plugs and wires. It idles rough and will run great when spraying crb cleaner into intake filter.
Fuel pressure regulator is the only thing left that can cause no start due to fuel problem
Check injector pulsation at injector harness with test light, with key on, disconnect harness at injector check for voltage, then reverse test light at battery and on the other pin check for ground pulsation while cranking engine, should have pulsation, if none bad computer, injector pulsation control by computer.
