Hi,
The box behind the tank is part of the vapor system and had nothing to do with the ability to get gas to the engine.
When looking at the fuel pump relays, are they directly next to each other, or do you have a vacant socket in between them?
Customer: replied 1 year ago.
Next to each other in car on left side corner dash

Thanks.
First let's get the relays in the right sockets. There should be a space between them, the two relays do not go directly next to each other.

Once the relays are in the correct position, place your finger tips on both relays them turn the key from off to on... Do you feel one relay click? If yes, turn the key all the way to start... Do you feel the other relay click?
Customer: replied 1 year ago.
There is only two relays but five slots. First one starts from coner then skip one . They both clicked

Great and great.
Please pull the back seat out and hold your ear to the fuel pump access while a helper cranks the engine. Can you hear the pump run while cranking?
Customer: replied 1 year ago.
No,but it's new - also if you take hose off and turn key it pumps gas out into floor pan.
Expert:  Doug replied 1 year ago.
Okay, so fuel is reaching the engine then?
Have you unhooked the fuel pressure hose (the one attached to the fuel rail with two 10mm books) and do not have fuel reaching there?
Customer: replied 1 year ago.
That's the problem hose connect to the pressure regulator does not get fuel to the rail. So no no fuel to motor.
Expert:  Doug replied 1 year ago.
The hose connected to the regulator isn't supposed to have fuel pressure, that is the return hose. The hose that bolts directly to the fuel rail is the one that gets pressurized.
Customer: replied 1 year ago.
Where s that located
Expert:  Doug replied 1 year ago.
On the end of the fuel rail, drivers side.
Customer: replied 1 year ago.
Fuel reach motor. The guy fixing car say there is no spark. How do you check and could it be fuel rail. Car was sitting for awhile
Expert:  Doug replied 1 year ago.
Okay, so it sounds like we were trying to fix something that wasn't broken :)
Lets start completely fresh here....
Pull the oil cap off and crank the engine (with a helper) while looking in the oil fill hole... do you see engine rotation inside the head?
If yes, take some starting fluid and shoot it into the intake at the throttle body, then try to start the engine, does it try to start at all (even if just a couple fires)?
Customer: replied 1 year ago.
with starter guild it did run for a couple of seconds but then stopped. Hasn t start since
Expert:  Doug replied 1 year ago.
Sorry for the delay, I had an unexpected event come up and I am going to be inaccessible for a few hours.
Did anything noteworthy happen prior to this condition forming? For example a computer being replaced, recent wiring repairs/modifications, or a different ignition key being used versus normal?
