Replacing Fuel Inj Pressure Regulator

Showing 6 out of 6 Posts
Question From Fixit53 on Replacing Fuel Inj Pressure Regulator

I have a 1998 Isuzu Hombre pickup. 2.2L 4 cyl eng with automatic tranny. It has 114000 miles, 14k of these on a new transmission. Was misfiring and running very rough and we replaced a clogged catalytic convertor. Ran fine for a week, now same roughness - diagnosis by repair shop says 80# pressure from fuel pump and needs regulator.

Is 80# in the acceptable range? Is there a fuel injector regulator for each cylinder or one for the system? How do I install the regulator?

Fixit53

Response From Sidom Top Rated Answer

That pressure is too high and could be the cause of your 1st cat going out. Spec are 41 to 47 psi regulated pressure.

The regulator bolts on to the end of the fuel rail and is fairly easy to replace. One thing to double check is the return lines to make sure it isn't blocked or kinked, that to will give you very high fuel pressure....

Response From Fixit53

Is the fuel rail separate from the upper and lower intake manifold? Should the regulator replacement take care of the pressure so that a fuel pump doesn't need replaced at this time?

Response From Sidom

The rail is separate from the manifold but the upper one may have to be removed to access it.

As far as the fuel pump goes, having to put out that type of pressure has been twice as hard on it, similar to running around with a restricted fuel filter so only time will tell if this has taken a toll on it..........

Response From Fixit53

Thanks!! I'll give it a shot. I've replaced a bunch of the little stuff like alternator, belts, battery that I don't want to part it out yet! Thanks,again!

Response From Fixit53

Thanks for all of your advice! With three boys and all their cars and my full time job, I just got it fixed. The regulator went in without removing the upper manifold. It was at the firewall side of the rail and I was able to reach it without too much trouble. Thanks, again!!

90 isuzu trooper i-tec stalling

Question From waldow777 on 90 isuzu trooper i-tec stalling

Ok. I just bought this old trooper and in ran good on the test drive. 50 miles later it started to spit and sputter while loosing power. Check engine light came on then went off. So I turn the key off and back on. It runs perfect for a while, then the same thing again?
The battery, plug wires, cap and rotor and plugs are all new. What resets when the ignition is turned off then back on?

Any help would be greatly appreciated....

Response From Hammer Time

Have the codes read first.

Response From waldow777

Im getting a code 4 and 12. What do they mean? I got the codes by connecting the two wires under coin tray together.

1994 isuzu rodeo/wont start

Question From jodi21 on 1994 isuzu rodeo/wont start

Hi so.... my friends rodeo wont start... she had fuel injectors,sensors,fuel pump changed...and yes there is gas in in :) The fuel pump doesnt come on or make that humming sound its suppose to make to let you know its working. we took it back and had it tested and at the suto store the mumming sound comes on! any suggestions?

Response From Hammer Time Top Rated Answer

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.



Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.


2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.


3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Lost on this... power loss and misfiring

Showing 4 out of 7 Posts | Show 3 Hidden Posts
Question From Nodd on Lost on this... power loss and misfiring

2002 Isuzu Axiom XS 3.5L v6 - Distributor-less ignition system, Coil-On-Plug system (each spark plug has its own coil pack)

Symptoms are loss of power and misfiring (P0300 random misfire), rough idling, when I put it in gear the RPMs drop to like 600 and sounds like it will stall. Check Engine blinks which means it is having misfires.

If I unplug any of the passenger side bank spark plug connectors it basically stalls out, but when I unplug any and all of the driver side bank spark plugs it doesn't stall and you can't really tell the difference.

What happen:

The water pump went out and the engine overheated. Me and my friend put a new water pump on, but it's behind the timing belt, so I brought it to a garage and had them do the timing. They said they hand cranked it several times and the timing marks were lined up every time. About an hour after this happen, I started it just to move it about 50 feet to another road and left it there. It was running fine.


What I have done since it's been out of the garage:

  • New spark plugs
  • New fuel filter
  • New EGR valve (took it back because it didn't fix problem)

  • Tested:
  • Compression (Each cyl was between 168 - 176 PSI)
  • Spark, coils (didn't check resistance)
  • Fuel pressure (42 PSI, specifications call for 42 PSI - 55 PSI, so we changed the fuel filter just in case)
  • Fuel Injectors (~76 OHMs)
  • Fuel Injector Connectors (with a NOID), all good
  • Air filter is good



  • Could it be a head gasket even if the compression was good?
    I don't think it's the cat converter because it ran fine before it overheat.

    Response From kev2

    42 psi sounds low end*. try this check fuel pressure then with KOEO observe fuel pressure drop- lets us know drops xpsi in 5min.
    plugs - did you use correct plug? do not switch brands.
    are there ANY other codes- be sure code reader will read all codes.
    are the plugs on drivers side firing? easier said than done but a can do.
    might want to look at plugs- wet dry black tan-


    the flashing indicates cat damage is likely if not corrected soon
    *if your spec is correct plan on replacing pump as cold weather will be demanding.

    Response From Nodd

    I believe they are the Autolite Platinum, part number AP3924.

    There are no other codes. I have the Actron CP9125 OBD II code reader.

    Plugs are brand new, I used a spark plug tester on all plug boots and they spark.

    I'll check the drop in PSI tomorrow. Right now I'm thinking the garage didn't time it right, but the marks were right on all 3 pulleys.. I put it back together and checked them.

    Response From kev2

    your code reader - I think it is limited not capable of all codes esp manufacturers specific, those that could help with cam crank sync.


    your description suggests driver side is not firing.

    Response From Tom Greenleaf Top Rated Answer

    Autolite in this engine? Unless something new those are wrong plugs no matter what claims they had,


    T

    Response From Hammer Time

    I agree. That should have NGK

    Response From Nodd

    Ok, I will switch them out for NGK.

    I went ahead and brought it to a different garage because the only things I got it down to are timing and cat converter and no way the cat went out like that..

    The shop verified that the timing was set wrong. They said the pulleys are spring loaded and there is a certain way you have to do the timing on it.

    So when it's finished on Monday I will go back to the first garage with the receipt and demand a refund because the timing they set was way off.
