whats the best way 2 test a fuel pump ? 2 see if it's any good or 2 see if it's the problem ? ..
the moter is turning . but it's not geting any gas ,, i checked the main relay . & no change .. it clicks when i turn the key . & the ecu isn't flashing any codes ? but it has a check engine light .. i tryed a diff ecu , no change .. so im leading 2 the fuel pump

 

bump

 

all fuses are ok? you can unbolt the fuel line going into the fuel filter on your firewall, take out the ECU fuse, and have a friend crank it over while catching the gas in a suitable container to make sure gas is getting to the fuel rail.
is this an intermittent problem? did the car just die on you while driving?

 

well i pretty much tryed what u said but i unhucked from were it goes 2 the fuel rail .. & didn't take out the ecu fuse . what does taking the fuse out do ? .. no i was doing a moter swap on the car & now it wont start

 

taking out the ecu fuse eliminates your ignition system, so no sparky while youve got open fuel lines under your hood.. obviously, for safety reasons.
If your pump was working fine before the swap, I really doubt thats the problem.

What engine and car are we dealing with here?

 

Check for fuel pump humm...if it doesn't then pull the backseat or cargo box and check for power at the fuel pump wiring. If you're getting between 10-12v then the pump is probably bad.

 

i put a hf moter in a si ,, it's what i had laying around .. & i now that i think about it .. i dunno if it the pump was working be4 hand . i just know it was trying 2 turn over .. but never did . the car had set up for like 4 years but it's not turning on or humming

i was gunna pull one 2night put it started raining

 

Fuel pump is not humming? Main relay is clicking? CEL light is flickering but no start? Themostat housing ground. If that is disconnected, no fuel pump and no start. If it is not that, pull out your main relay and test it.

 

aahhhhh

i replaced the fuel pump . & it still doesn't want 2 start . it's geting gas . but still not starting
fuel pump is coming on . relay is clicking .grounds are hucked up , cel light comes on for like a sec ? but still no code on ecu .. is there a way 2 test the ground wire ? mybe it has a short ??
