ok so how do i check the pressure regulator

 

With a pressure guage.

 

thx man i just wanna narrow down the problems so i dont overlook anything.

 

also what do yall think of an aftermarket pressure regulator like this if the regulator is bad.

I'm not familiar w/aftermarket parts so you'll have to rely on another member for a meaningful response.

 

ok so i tested fuel pressure after filter at secondary rail and primary rail all good. so im starting to think the injectors are clogged. theyre getting 12v on each.

 

if im not mistaken the primary and secondaries should both be the same ? if so try and switch them out. and if your in a less densely populated area try a bump start or even a tow start. i had to do that the other night i ran out of gas and my injectors got clogged in the process. after the tow i had no problems with it. Also try and stick some fuel injector cleaner and a high ocatane gas. that will help clean it out too.

 

You think they would be the same volume?

 

An S4 NA from the factory came with four 460cc injectors.

 

What does the s4 mean

 

86, 87 & 88 RX-7's.

 

ahh ok still getting used to the terms

 

so m gonna try this and see if it works.

 

Just a quick adder to my previous post... I meant DVM as in Digital Volt Meter and not DMV. ;-)

Also, and I know this is probably a long shot, but if you know someone with a oscilloscope, check the either the connections on the resistor block or at the ECU while cranking and you should see the injectors firing. If not, that's why it won't run. If you are seeing injector pulses, then the fuel is not getting through the injector. They are either stuck or plugged. (assuming you have fuel pressure of course).

random thought i found this at megan's motorsport site. what do yall think? http://www.mariahmotorsports.com/ima...t_m5airdam.jpg

the front bumper and valence

 

even if you get the car running by switching the injectors, youll still new to replace the bad ones, because the secondary injectors turn on around 3500-4000rpm , youll be able to idle and drive but not anything after that rpm, your best bet is to get your injectors cleaned/tested see how they come out. you can probably find some injectors cheap on the forums on here, on my old rx7 i had a bunch of extra parts when i sold it for 300$

 

ok so its been raining cats and dogs everyday that ive been off. is there anyway to check primary injectors without taking apart the intake?

 

Most will tell you no and it would be an accurate assessment.

 

Any tips or tricks on safely removing fuel lines that are stuck from age?

 

Replace them with new hoses that are properly designed for the job. If you go down this path then you could just cut a slit longways down the length of the hose where it is attached and it will vacate the premises like butter.

 

CPR!
Cut,pull,replace!

 

Any good sources to find replacement fuel line, i want blue ideally. Although i wouldn't mind braided stainless but in the end regular gets the job done. Just a cool looking engine that some dress up would do it nicely. best prices and such.

 

Also, how do I take off the intake? Pics would be wonderful.

 

Im not sure if anyone on here has dont the delete for the fpd, oil injectors, and omp, but it was just done on my fc and it hasnt started up yet either. Primed the system, nothing, de flooded it by taking the fuse egi out, back in, nothing. Fuel injectors were all good as they were sent in to clean, rebuild, and test. So checking spark plugs now, so far one had a tiny gunk piece on the top, gonna check the rest and see if it'll start with starting fluid, if not am I not getting fuel somehow?

 

Did you ever fix the issue with your FC, I'm having the same issues with mine right now and its already had the fuel pump replaces and the lines were checked it seems like the gas reaches the engine and just stops. Was it your fuel injectors?
