So the guy I live with is convinced that all that is wrong with my xj is a fuel pressure issue. He says I can test my fuel pressure using my voltmeter and I don't need to go out a buy a fuel pressure gauge.

if you can I don't know how since the fuel pressure regulator has no electrical wires to it so I don't know how you would do that but then again you have a RENIX so it may be possible..

You can check your fuel LEVEL with an OHMMETER. I've never heard of checking fuel pressure with a volt meter, unless it is to just verify if the fuel pump is getting power.

You have to have a pressure gauge to check any of the fuel system

anything is possible when it comes to RENIX

Thank you!! Now will you tell that to the guy I live with???

You are correct to check fuel pressure gotta have a gauge..Like the post above you said you can test the sending unit with a volt meter but not pressure..Well unless there is some voodoo magic I don't know about and I have been known to be completely wrong so who knows..

Where are you located at?
Maybe someone can stop by and look at it, or at the least tell that "guy" to stick to ricers.

Renix are strange critters.

If he knows of another way to do it without any electrical conections I really would like to see it .On my 89 the only way to check it is with a pressure gauge.

This is the truth, no way to check with a volt meter.

Huh???? Is this the same guy who told you to find a code scanner for your Renix???

You need to tell him to stop trying to tell you things about your Jeep. Let him know you are going to ask us, cause we will give the right answer.

There is no way to measure your fuel pressure with a voltmeter, or an ohmmeter.. unless they are tied to a fuel pressure tester.

The Renix fuel pressure regulator only has a vacuum connection to it.

While you are testing the fuel pressure also do a flow rate test. This will give you an accurate picture of whether your fuel pump is getting the job done.

Autozone used to have fuel pressure gauges on their loan a tool program. Go in plop down a deposit and use it. Return it when you are done and get your money back

Im thinkin you should not hang around this guy too much. I look at our world today and stupid looks like it can spread. lol. Here is what I would try first. Sounds weird but it will relive alot. With the jeep running. Pull one spark wire at a time and put it back in and go to the next. If nothing changes you have eliminated alot of problems. If they way it runs does not change when pulling a wire. You either have a rod not moving or a piston or bad plug wire or plug. Would also eliminate if you have a bad dist or coil. This will change alot. and will really narrow your problem down.

Seriously! Just tell him to shut up, look pretty, and fix you a samwitch! :rofl:

 

[UNLIMITLESS]

Tell him to take the schrader valve out of the fuel rail and have him put the end of the fuel rail in his mouth as you try and start it. If he starts spittin and cursin you have pressure it just may not be enough!

This is not recommended

Really the only way to test is with a gauge.

mm...

wow...haha i dont even have anything to say.....

 

[Bluto]

i know i have a friend who has a 89 with the renix
and when it wouldn't start, he'd use a knife to push the schrader valve in and relieve the pressure, and it would usually start
but now he's gonna swap his tired motor and trans out for one from a 94
