Fuel pressure problems

[baza]

Need help yesterday I took my injectors out of the car to clean them
I put them back in and now I only get fuel pressure when I turn the
Ignition on i get 35 psi of fuel pressure but when the pumps stop the fuel pressure drops to. Zero
It's a Evo 3 motor before this the car ran fine
Thanks

Maybe need New seals on injectors or at least a bit of grease.

Is it running?
Because if it not, maybe it's the air in the rail that is compressing. Need to crank it a bit more to purge the air

No it's not starting up because there's no fuel pressure
I cranked it for about 15 mins this morning and no good

so before you did you injectors it worked yeah? spray some carby cleaner or startyabasterd around the injector seals towards the head while idling , if you notice a difference you may need to just replace your seals also

My problem is it won't start

this in no way is an insult to your intelligence but have had this problem before with some people . Does the car have fuel in it ?, next does your fuel pump prime at all can you take your rear seat out and get someone to just see if your pump is actually working , next thing would be to see if you some how crushed your fuel sender lines under the car , then check you dont have any vaccum leaks etc, and the injectors pulsing?

let us know how you go

please clarify..."the pump stops"

why is the pump stopping?

next.....is the fuel supply line to the fuel rail kinked?

was there any protective tape over the heads over the injectors?

get someone to crank the car while you hold the return line over into bottle...that will tell you if the pump is running during crank condition.

Car has fuel in it both of my fuel pumps are working as I'm running two pumps one in the tank one in the engine bay
What i have found out is my sard fuel pressure reg has shit it self

To test, simply get some pliers and crimp the return hose line. then start the engine. if it starts, you know it is the regulator. if not, it probably is something else.
