Roundabout136

Car is a 1994 n/a.

To make a long story short, I replaced 3 injectors. I pinched one lower o-ring so I pulled the plenum again, and replaced the screwed up o-ring. Gas got into the oil, so I changed the oil and filter but haven't driven it at all yet, just started it up a few times.

So this morning before class I went out and started the Z, let it run for a few minutes and shut her down just to make sure it was holding fuel pressure.

After the o-ring install on the injector my FPR has been noisy while pressurizing the system. Noisy like moaning loudly for a few seconds. Have you ever heard of this before? After turning the key to on (pressurizing the system) I run quickly over to the engine bay and if I put my finger on the FPR it is definitely coming from it, I can feel it vibrating almost while making the noise.

Now, I did install a new FPR a while back from z1 while doing some maintenance, could it be damaged somehow? I don't know how it could be damaged, there's MAYBE 250 miles on the new FPR.

Question number 2. I checked for codes a few minutes ago and got 55. Doesn't make too much sense to me cause the EGR temp sensor is unplugged and I haven't put the resistor in it yet. (I was getting code 32 for about two weeks)

But while checking for codes, it did something I've never seen before. Instead of it blinking completely it like half way blinks, with a background light still lit. You can see the light blinking well, but it's not coming on and completely off for a full blink. Every other time i've checked codes it blinks fully, on and off for each blink. Hope you guys understand what i'm talking about here.

Thanks

Noisy FPR can be caused by sitting without fuel. I don't know if it dries out or if it's caused by air, but my car made the noise for several minutes while I primed the fuel system for the first start. Went away after a while and hasn't come back since.

Ok that makes sense. I think the car just needs to be driven.

Zlover, any idea about the code issue? I've never seen/read anything about it before. I searched and searched and couldn't find anything.

yeah f-in drive your car you ****. i don't get what you're waiting for. oh yeah, for the tires to be sitting on the rims lol.

but yeah, i'm pretty stumped as to why everything is all good once we unplugged the egr temp sensor.

I'm changing the oil one more time tomorrow and it will be driven haha.

I'm stumped also. Not only that but why the hell is my CEL not fully blinking while checking codes. It doesn't make sense.
