Hi guys,
I've been troubleshooting my 1996 toyota tacoma 2.4l 2wd,
My car running fine at idle but when I accelerate truck have no power and also pop pop sound coming but if i accelerate slow it will catch up, pressure reading not at fuel trim but at supply line, 18 psi at idle, drop a little when I accelerate to 16 psi then stable at 19 psi, MPG is terrible, I have replace fuel filter and check the fuel pump, voltage drop only .2, resistance between fuel pump is 3.6 ohms, i also checked the fuel pressure regulator open at 55 psi and I have notice there no fuel come to return line. I have no ideas what cause the low pressure condition. Please help, any idea is much appreciate. Thank you.
