The Fix Jim's Van thread
« on: Dec 07, 2015, 04:16:11 PM »
Can anyone physically help me in the East Bay, Northern CA area?

Need help to perform a leak down test, compression test, and block test

I don't have any of the tools, but should be able to rent them, and/or buy them to do this.

I may have an issue with having a crack in one of my heads, I get multiple cylinder misfires and a cylinder 4 misfire. I also have another issue with my o2 sensor heater circuits and over voltage (both are unplugged right now though, long story, but need to be replaced, I just don't want to replace them, have them go bad because of this other issue, and then have to replace them again)

I do have a very weird schedule, but we can hopefully work something out if you are available

in Pleasant Hill, but can drive a little ways if need be.


1996 Dodge B2500, 3.9L. Automatic

Looks like I am doing this stuff myself.....
Well, at least the block test and compression test. Rented the tools at autozone, and watched some youtube videos....

as I wont have a helper, is 5 seconds enough crank time? Also, I saw I should floor the gas while cranking? Is this correct?

Hopefully it doesn't rain tomorrow

disconnect the coil, pedal should be to the floor, 5 sec should be adequate

Which is how I would like to do it, but I may not be able to see the gauge from the driver's seat. Then again, I might, as the engine sits half in the cabin, and has a doghouse over it, which, will of course, be removed.

no, I only did a dry compression test.... they all held there same pressure for at least 2-3 minutes, the only one that showed any loss (and this was after like 7 minutes, was cyl 1 @ 122 - lost 3 psi)

It looks like your compression numbers are fine, i.e. not the cause of your misfire.  You need to focus on Cylinder 4, since that is the one identified by the code.  A quick check online shows you probably have a distributor.  If so, spark plug wires & spark plugs are the first thing to look at.  If you have a coil-on-plug system, the recommended diagnostic step is swapping the coil from the bad cylinder to one next to it.  You then clear the codes, & see if a code returns for the cylinder you switched that coil to.

Hope that helps.  I will be in San Ramon on Friday for training, but get in late Thursday and will probably leave ASAP to beat traffic.

I do have a distributor, with a single coil

plugs, wires, cap, and rotor were changed, and the problem still came back

there is also a TSB for the Dodge 3.9L that had an issue with cylinders misfiring due to cross firing, I have performed that, to no avail (Weird though, as the TSB covers the Trucks, but doesn't cover the Van...)

all the plugs look good (as they were all out yesterday)

Yup, pretty much knocked all of that. Fuel pump and cat were recently replaced, well, same time as all the other stuff. The new fuel pump actually fixed some other problems that it was having

article was checking spark plugs for cracks in ceramic on plugs, also fuel injector may be causing, if you can, clear codes, switch no 4 injector with another one, if code comes up on other cylinder, you know injector is problem

It isn't only 4, it is multiple as well

Will see about switching the fuel injector, possibly later today.

All the plugs looked the same. No damage of any kind. Problem was there before I changed them, and after as well

Most vehicles will set the P0300 anytime at least one cylinder is misfiring.  The system uses crankshaft speed to determine which cylinder it is specifically, but others may appear to be misfiring due to overall rough running.

It actually runs like a champ. Gets about 14 mpg. It is heavy, like 6000 lbs with a V6 and just a 3 speed automatic with no overdrive

ok, changing the injectors looks like a pita...... but.......

here is something else....

So I ran the codes just now, I get P0135, and P0141 -- O2 sensor heater circuit codes: bank 1, sensor 1 and bank 1, sensor 2

as far as my I/M -- only CAT and O2S are tagged --- Haven't driven much since yesterday, but some, and HRT did become ready since that time





should I get the new O2 sensors or wait? I was told that misfires will wreak havoc on the O2 sensors, and I don't want to have to buy another pair in a week or 2.....

as of right now

and the only things that are tagging are the O2S for the heater codes (duh, I have no O2 sensors) and the CAT (If I understand correctly, uses the O2 Sensor heater circuit to figure out if the CAT is working)

I am going to go out there right now and see if I can get that injector swapped, just to see




what is kinda funny, was I was chattign with the worker @ Autozone, and he was like, oh, well have you tested all your fuel injectors......

ok so  swapped them out, took 11 minutes... haha, wasn't that bad once the air cleaner was off, and I found a 1/2" socket

just swapped it with the one behind it.... they did look pretty clean... if that matters, no build up r anything.....

now I smell like gas, lol

I have had the codes stay gone for awhile before...... so we shall see if this lasts.....

I am also going to have to buy some bullet connectors, as the factory connector is gone now, on at least one of them

is there a way to check the heater circuit?

had those codes before, I swapped to the new ones, then with the new ones, they came back

without any codes, youll never know, if the code does happen to come up, and it different well...., I would get some 02 sensors, and see if you can clear codes

the oem wires on the bank 1 sensor 2 are white, green, blue, and black


my sensor has a black, grey, and 2 whites.....

need to figure how to properly splice these back together
