yeah i actually got code i believe it was p0300 which indeed it is multiple misfires but when i hooked up a good scanner I indeed had a huge misfire on number 7 anyways so i dont want to think i have a bad fuel pump and injectors and I have to drive the car like that since I dont have another car damm

Yup. That dammed P0300 code. It narrows it down to like thirty different things.

sry. Made me laugh.

Like said, I'd drop the tank or do the "trap door" trick in the trunk to check the pump

Pull the plugs before you do anything else. When you do, post a picture and we will look at them with you!

im sure plugs are not the problem im leaning towards injectors, like I said car was running near perfect before the running out of gas incident, and before the racetronix pump, ill take out the pump and take a video of it

It's possible that injector is plugged. When you in your car down that low your sucking sediment off the bottom of the tank. It CAN pas through the filter, pull your rails off and look at the top of your injectors

can they be fixed by a cleaning

Can anyone tell me how I can manually prime the pump to make sure it works? is that the only way to make sure?

Way way too much jumping around...
Troubleshoot first, using some logic...
Most obvious thing is your fuel pressure is half of what it should be, and leaks down quickly.

You have to fix that problem before considering anything else

i would of checked the spark plug and wire first....

When you turn the key to "on" without starting the engine, you'll hear the pump run for about 4 seconds. The PCM will shut it down when it doesn't see any cranking or running.

This is all the priming you should need to get a pressure reading.

Please confirm, when you do this prime with a pressure gauge on the line, the pressure is half what it should be (60PSI)?

I still say you pinched or crushed a line.

I do here the pump working so im thinking it is a crushed line but how can I know??? like how can I check?

Paul Bell

You may not wanna hear this but you'll need to drop the tank again.

have the trap door method so no issue their just wondering how to check? how can I check for a bad pressure regulator?

updated first post

Updating your first post and then posting a reply saying you did that is confusing. Just post a reply. People following along look at the new replys as they get posted.

==========================================

Are you still having issues? Have you checked the lines around and above the fuel tank?

bwkmaro

your number 7 injector if i remember correctly is one of the furthest from where the fuel comes in to the rail so it is last to get fed. so 30 psi is "enough" to feed the rest of the cylinders but once it gets to that point there just isnt enough fuel left. but before you go pulling the pump again i would by all means change your filter again

I'm quite sure whatever pressure is in one end of the fuel rails matches the other end. Pressure presses upon the entire inside of a pipe or tube equally.

The exception is water pipes going up in a tall building. The pressure at the bottom is greater than the pressure at the top.
