replaced my fuel pump a few days ago, tryed to start it but it didnt start, changed the location of the relays from the fender to the firewall for better ground, fuel pump now kicks on, but not getting fuel to the tbi.....what is wrong here??

 

There is a jumper on the firewall directly behind the throttle body and air cleaner, it is a single wire clip. Jump this wire to the 12V positive there. If no fuel during starting out of the jets then change fuel filter, or maybe youll have to pull the tank down to check your work. You could alwaysdisconnect fuel filter or somewhere along the line to see if fuel is coming out of the hose, then good hopefully. You need 9 to 13 psi coming from the fuel pump to start the engine, but testing it on these is a bit3h.

 

im a novice mechanic at best...im going to need direction...forgive me

 

Start by having someone crank the engine with the top of the aircleaner open and check to see if there is fuel coming out of the 2 jets pointing down into the intake.yes or no.

 

Hopefully you purchased a delphi or ac delco pump,and not a airtex...

 

alright so...disconected the sending line and its getting up to the TBI but not spraying out the jets...whats wrong...

 

bad jets ? whats the fuel pressure ?

 

not sure of the pressure...but ive tried 2 different TBIs....and still nothing, a stock tbi and a holley

 

id get a fuel pressure gauge and start from there

did you replace the filter with the fuel pump replacement ?

did you check the lines for leaks or kinks ?

 

where can i find a gauge and where do i attach it...
and did not replace the filter...i took apart the holley and there was fuel inside it, but its just not coming out the injectors....im thinking it might be the computer?
