there should be a port by the firewall on the fuel line

for a gauge you can borrow one from the auto parts if they have the borrow program or you can buy 1

if you test it the pressure should be at 15 to 16 psi at least

 

If the TBI unit isn't getting a signal from the computer, then the injectors will not open. Make sure the wiring is good. If it is, time for some testing ...

 

okay im getting fed up with this thing...im at a loss here, i dont know what else to do...

ive replaced the fuel pump ((Bosch)), tried 2 different throttle bodies, and even changed out the computer, what else can i do????

 

figured out the problem....@*#!$ ground wires....so it is runnin now, but its horribly out of time and still needs brakes bled, and some tires,,,,hoping i can get 'er finished before the snow hits

 

If it is "horribly out of time" make sure you got the plug wires in the right way. The #1 starts on the oppisite side of the block on the 2.8L compared to normal chevys. And 1 starts on the distributor cap at 7 oclock and goes around 2,3,4,5,6 clockwise.

 

its now running some what decently....can back out....but when i try to go forward, she chokes out and dies on me no matter how gingerly i am with the pedles....

 

check the fuel pressure, 9 to 13
