Fuel pump issue with results
OK so i come out this morning to test fuel supply on truck,
i drove it last night, so there should be a reading immediately without turning the key on correct? cause the gauge read zero which tells me the regulator isnt holding pressure?
So when i turn the key i hear the pump do nothing really, and the gauge barely moved. cycled key couple more times then pressure was rising but when i turn key off the pressure immediately drops ,
will post a video if someone needs
while truck is on it flucuates between 48-50 really bad, when i gas it while running it drops to 46 , and when i kill the truck pressure goes back to zero instantly,
gas looked a little discolored ( tanish ) coming from my drain line.
when i turn key back on after test, takes 3-4 cycles to reach full pressure.
is this a pump/ regulator/ clogged fuel rail problem?
my truck has Long start issues, bad fuel economy and miss's bad espcially when low on fuel and when it first starts up, ( i have done new Coil/cam censor/ cap/rotor/wires//batter / plugs
(gutted catalayic converter ) new oxygen sensors, new IAC
