  1. I am currently dealing with the problem of not having the #2 injector firing or squirting after having both of them rebuilt by GB Manufacturing in Long Beach, CA. The injector tech told me all rebuilt or remanufactured injectors are bench tested for spray pattern and OEM volume.

     

    The tech that diagnosed this repair was trying to determine why my VG30 was going into 'fail safe' mode and limiting the RPM's to 2800-3000 PRM's before the truck started 'bucking' and jolting until the rpm's dropped below 3000 RPM. (CODE 51) from the ECU.

     

    He says he has a signal to the injector from the ECU, but the injector wont fire.

     

    Has anyone else encountered this? Could the TPS cause the problem. Also what is the correct procedure for clearing the fault codes from the ECU?

     

    I'm just throwing possibilities out there to see if anyone else has encountered this. Been working on it for 2 weeks and growing frustrated, as the problem started all of a sudden. Otherwise the truck runs and warms up normally until 3000 RPM is reached and 'Fail Safe' kicks in!

     

    Thanks for any help or suggestions.

    I'm having a similar problem, if you find anything out please share!!

  2. just replaced both injectors, still not running right so we took a look and the injectors seem to be stuck open, but theyre both new. could this be a wiring problem? and i cant rev over about 2300rpm

     

     

     

    also does the temp gauge hook up below the right manifold? saw a plug just laying there not hooked up..

  3. where the wires com e off the injector and go into the clip thing the back of it should pop off and you pull the injector wires out from that end of the deal (im a little late on getting here) but i just replaced a injector on my 88 a week or so ago, did you get a refurbished one or new one?

     

  4. Today I put new wheel cylinders in and new calipers on and the light went out. Something was just pestering it I suppose, another question, brake related

    After we got done bleeding the brakes we went for a spin around the yard, pedal brake pedal froze up and hit the floor, took off the vacuum line off the booster and it became free, I suppose this means I need a new booster?

     

    She started to idle today after we took apart the throttle body because one injector isn't working. After having replaced the other one so we tried to use the old one again and it doesn't work. So both injectors went out and are giving me troubles, could the one not working cause a bad idle rpm? (Sounds like it's turning 5,000 rpm with the pesky exhaust leak)

  5. 88 pathy 2 door v6 throttle body,

    Rebuilt the throttle body, got a new injector, put it back together. She runs and won't idle cold or warm.. Replaced all the dry rotted vaccum line,

    Right now I'm having to do the brakes.

     

    The background on the pathy:

    It was my fathers and it needed new tires and shocks so instead of spending the money on it he let it sit. Till I got bored one day and decided to make her ride again. So far we have had to get new slave cylinder, master cylinder, vaccum lines, gas tank and fuel pump, oil change and soon brakes

     

    Any tips, tricks?

     

    Also the brake light stays on for some reason.

  6. Unplug power from the injectors and see if they stop spraying, that will let you know if its electrical (ECU grounding and holding the injectors open or a wiring short). If they keep spraying you'll need to pull the throttle body and remove the injectors. You could try and have them cleaned, tap on the body a bit, or stick them in some lacquer thinner/ acetone to eat away the gunk. Even better if you have a jewelry cleaner.

    Unplugged them and they kept spraying now gonna pull them out and try to clean them up, thanks for the help

  7. Treat it like a tbi maybe you will have better luck. Make sure u have iac and your injectors are spraying properly, perhaps give it a tune up and make sure your fuel filter flow is going the right way

    My tbi injectors are stuck wide ass open and pissing all over the place...we turn the key to ON and it just straight starts spraying fuel and when i mean fuel like holy @!*% stand back. i flooded the motor please help us out and if you of reasons to why it would be doing this please respond.

  8. A few weeks ago a buddy and me started to fix up an 88 that had been sitting around 10 years. we have replaced all the vacuum lines (about 1,000 miles) and fuel lines, got a new gas tank, fuel pump, fuel filter and cleaned out the carburetor, did an oil change. new slave cylinder and master cylinder. we got it to start and drove it around the yard but now she just wont run or idle or anything. This weekend we are gonna re-build the carburetor, Anything we should check on that might be wrong? thanks
