fuel system test without convenience of test port
fuel system test without convenience of test port
Hi all, nice to see that there is a forum for just about anything specific out there!
I have a '95 2.2 Litre
Currently I'm trying figure out how exactly to check each individual component of the fuel system. Every now and then it will die after starting up. But after starting again, or after a couple times, it will stay running. Could be leaking injectors, dying pressure regulator or pump...wish I had the test port on the rail.
My question to anyone who may help is, how do you do the various pressure tests when you don't have the Schrader valve to conveniently connect to. I've looked around on the net and yet to find a straight answer. Figured I better ask directly on a message forum. I did see someone talking about a device which goes in place of the fuel filter, and then about a t-fitting-just no concrete, exact how-to's.
Thanks to all who can help

Sounds like a bad fuel pump, they only cost like $50 for a brand new one and are fairly easy to put in.

Don't throw parts at your car, you'll just waste money that way.
If you think it's a fuel pressure regulator pull the vacuum hose off of the regulator and try starting the car, if it acts the same then I would replace it. it's one of the cheaper things to replace anyway.
your Idle air control valve may be bad now that I think bout it. once you get the car running, unhook a small vacuum line, and slightly cover the hole, keep the size of the hole constant. the Idle air control valve should compensate for a small vacuum leak, if not that may be your problem. but sice those are rather expensive take your car to a dealer and have it checked, they have a special tool for them.
I don't have a whole lot of experience with the OHV 4 bangers, So I'm sorry if I'm not much help.

Thanks guys for the response, I will definitely be checking those which you spoke about. Would be nice if it's just the regulator. The IAC valve, I remember taking off and cleaning up a bit when I did the rebuild this time in '06...Thankfully I can just grab one for cheap at a pull-a-part not too far.
I'd still definitely be happy to do my first fuel system test (have yet to do so), and narrow the problem to the exact device. Again, thanks a bunch for that info you provided.
Anyone else out there ever had to do a fuel system pressure test? When you don't have the test port to attach the gauge to?
Thanks
