No gas getting to engine

ok well the title says it all... the fuel pump turns on; we got pressure at the fuel rail but nothings getting to the engine. you can even hear the build of pressure. the fuel pump turns and theres so much pressure it sounds like its being over worked. the injectors aren't opening up and the have 12 volt power. Is there hose that needs to be checked? wires?

Re: No gas getting to engine

There is a rubber hose between the tank lines and the steel lines on the car that could be kinked or swelled shut, filter could be totally plugged (unlikely), metal line could be kinked, or rubber lines from steel lines to the engine could be kinked or swelled shut, or worse the connection from the actual fuel pump to the sending unit could be swelled shut or even blown. Hope this helps.

Re: No gas getting to engine

Your not getting spark or fuel from the injectors . Sounds like you may have a bad ignition module .

Re: No gas getting to engine

yeah i took out the ignition module and got it tested at a shop and it was good.

I found a disconnected ground and put it with coil ground. {Is that a good ground?}

Does anybody know where all the grounds are?

i need to check them all.

I think I'm not getting gas because after a few times of cranking, i pulled out a spark plug and smelled the tip for gas and i didn't smell anything.

I only have until Wednesday to work on my car to work. so any help is appreciated!

yes sir, there is spark but its sooooo low i hardly felt it ( i used my finger to check for fire )

I'm pretty sure not all of the grounds are on, id really like to know if someone could help with the ground issue. i check how many volts i was getting in the fuse box and i should be get 12 but i have 4.
