Hi, I’m new to this, I hope I’m in the right place. My 95 Mazda B-3000’s fuel pump has been giving me a crazy hard time. I did the lazy thing first and replaced the filter on the frame with an electric pump. It worked for a while then stopped. I took off the bed, replaced the pump and put the filter back (new obviously) that worked for a while then stopped. Not wanting to take the bed off again, I replaced the mass airflow sensor, fuel pressure regulator and relay. It stopped working again. After I took off the bed again I tested the power at the pump plug, it said 6.5V. Some things I looked up said some vehicles step down the voltage when they aren’t revving high. Since after replacing the in tank pump again and it ran, I thought I was good. It’s back to not starting, starting a little then stopping if I prime the pump a lot (pump turns on for two second like it’s supposed to and the check engine light blinks off indicating it’s seeing the RPMs. It will run for a few seconds on starter fluid. It’s getting low pressure at the fuel rail, Is it the low voltage? I’m getting 12V at the impact switch and I even bypassed it and got nothing. Please help before I light it on fire and by a bicycle
