I can’t seem to get fuel pressure when I turn key to ignition on ?
When I crank the car to start , then it will pressurize and start the car , idle and run like normal . I’m guessing it’s running off the Oil pressure switch .
It’s a new build. I’m in my break-period so just driving around with low boost . My previous engine I would have fuel pressure with key on . Not anymore .
I went with E85 on this build so I got a new DW400 pump with a different hanger. 120# injectors . I changed to a new diaphragm on my Kenny bell fuel pressure regulator.it also has -8 &-6 fuel lines .
So far I have checked the fuse on the fuse box...It’s okay .
I’ve replaced the fuel pump relay with a new one . The one on the fender ...no change.
I’ve check pressure with another gauge .... No change
I thought it was my hot wire so I switched the tank wires back to stock and bypassed my hot wire ...No difference.
I just tried adding power to the fuel pump via the connection behind the alternator and I got fuel pressure! GREAT !? but when I did that , I here some sort of pressurized noise around the fuel injectors area. Are they spraying ? It sounds like they are . As soon as I stop touching the alternator terminal to give it power , my fuel pressure drops back to Zero . What can be going on ? I pulled a plug . Looked kinda wet . I put it back and tried starting the car , it was having difficulty this cold start . It eventually started . Ran her for a minute or two , rechecked the same spark plug , looked dryer than when I first pulled it .
so can my injectors be leaking ?
The injectors ( Precision) I bought used but service at Fullthrottlespeed and shipped directly to me from Fullthrottle. Do they give the customer a test print out ? Just got a recipe. Anyhow
Some more info ... when I purchased the DW fuel pump from a member here , it was new in wrapper . But it came with a new but use fuel hanger . I never asked if it was for a digital car ? Mine is analog. Wasn’t sure if that can cause a problem. I will post a picture of the side by side hangers .
Any help would be appreciated.
