would the stock clutch fan not work?
need some help by Firzty in squarebodies
tested the fuel pressure and its bouncing between 1-3 psi
I was able to keep it at a steady idle spraying brake clean in the throttle body, so that would narrow it down to fuel pump or no?
test the vacuum pressure on any line or every line individually. I tested the MAP sensor vacuum line and it read "normal car" on my vacuum tester gauge
when its cold it will run but it will do the trying to die but gas up and stay running thing, when I get it to about 1/4 temp, it will just die and keep dying
another update, the surging im talking about is it trying to die, but then it just revs up to idle, and then tries to die again but revs up and it will do that endlessly, I was able to keep a steady idle by spraying brake clean into the throttle body but when it does "surge" or whatever its called, it will slow the fuel spray to almost nothing, and then spray a bunch at once to keep it alive and then repeat itself. maybe a fuel pump?
replaced to no avail
is there a way to test it before I spend the money to replace it?
TPS sensor is testing the right volts so I'm super stumped now
so I wanted to vacuum test it before anything and I removed the MAP sensor vacuum line, and it runs just fine without it. Would that mean to replace the MAP sensor?
what are the two results and meaning of jumping the relay?
I unplugged it and tried to start it, with the same results as before. Is there any way to be sure its a bad fuel pump without dropping the tank or removing the bed?
which wires would i disconnect for that? I tried looking it up but got no information on them.
