ascany169 -> 96 4.3 low fuel pressure (6/27/2008 1:50:10 PM)
|
I''m new here hoping to find out why/if I have low fuel pressure. I bought this blazer not running from a fire under the distributor (former owner had his fuel line o''rings on the rong side after new top end) I got it running but ran into some shorting issues so I replaced the wiring Harness and all other damaged sensors/distributor. now I have it all back together, everything is perfect but no start. the schraeder valve was leaking so I thought that was giving me bad fuel pressure. I tightened it down and still no start. I''m wondering if I have a coroded connection in my fuel fump circuit, causing low amps to the pump, or if the regulator isnt kicking the fuel pump back on for starting.
where should I start? where does the fuel pump power run? how can i test the relays on my fire wall? book says there should be 4, i have 3... and a few spares (have doner 97) did i miss something??? will repost when i get my hands on pressure guage (kinda stuck at the moment)
