yesterday i wasn't sure if my fuel pump was getting power - or if my injestors were getting fuel - so i removed my injectors and my spark plugs - put my injectors into yogurt cups and turn the engine but no fuel.
i pulled my stock front mounted fuel pump and it did not make any noises when i turned the key. so i hooked up a volt meter to the fuel pump power wire - i was getting power - so i assumed my pump was bad. this morning i go out to the car and turn the key and the pump runs - so i turn over the engine some to see how fuel is going thru my injectors into the cups - they all spurt fuel - so i put the injectors back in and the plgs back in - and then - bam - the fuel pump is not getting power again?? i swapped out several reays - no success? http://www.youtube.com/watch?v=PrLcva9o8LA http://www.youtube.com/watch?v=8pipbKl_ZQU http://www.youtube.com/watch?v=bOAhJ9OZpm4 http://www.youtube.com/watch?v=9gMp0eoXvYc Attached thumbnail(s)
