OT - Working on the minivan
Mrs. CRWLR called me at work today to say that our van was riding around on
the back of a flatbed. I checked spark, there is none. She said that power
loss was gradual, not sudden. That said, it gradually lost power but she
still couldn't get in into the parking lot and had to bail out in the
street. She described the motor as lagging in power, and missing as it was
going down.
I am inclined to not go after the CPS (multiport injected V6 in a Mazda
MPV), mostly because I don't know where the damn thing is, but the coil and
igniter are right on the fender and easy to take off.
The igniter (it says igniter right on the side) has a 5-pin connector, the
pins are marked in order C G B IGt IGf. Is there a way to test this device
with a multi meter to determine if it is serviceable or not? The wires that
go to the igniter also appear to go to the coil and a gizmo that looks for
all the world like a huge transistor.
The assembly that contains the coil includes the igniter, and another device
that appears similar to a transistor. The transistor has one leg grounded to
the frame of the assembly, and two other legs that go to a connector. All
three of thest parts appear to be interconnected; I say this because of the
shared wire colors, the wires actually all go into a loom, then come out
again on another connector. It is difficult to tell if the wires really are
the same, but a few test with my multimeter will get this sorted out.
My main concerns are, can I test the igniter thingie, and can I test the
coil?
I could simply exercise the checkbook, but I prefer to understand stuff more
complicated than the Bic pen I use to fill in the blanks.

Re: OT - Working on the minivan
Hmmm, did you check the gas ?? :-) Did she just happen to have filled it
up ???
See if you have fuel pressure at the fuel rail first, then look for spark
by pulling one plug and setting it against the engine. I would do that
first before digging into the electronics.
I would really check the gas though, ever since I got my 98XJ I have an
innate distrust of fuel gauges.. I've considerd mounting mine face
forward on the front corner post and let it do 'jeep waves' for me.

Re: OT - Working on the minivan
What year is the van? If it's newer than 96 (or maybe it's 98) you can get a
code at any parts store. Have them hook up the machine and print the code
for you.

Re: OT - Working on the minivan
There is pressure, and very little return, during engine start. There is no
spark.

I have a Snap-On (costs a little more than $150.00)
If you live near Yuba City, come on by & do it for free here......

Re: OT - Working on the minivan
Our 87YJ died like that a couple of weeks ago, I shot gunned it with a
new cap, rotor, wires and coil. Finally strapped it to a shop 3 miles
away [now I know why straps are no good for towing, they make nasty
noises when they go under the towed wheels] and paid $80 for a diag,
turned out to be the ECU under the w/s washer bottle, plunked down $90 at
National Auto and stuck it in. At least it does not need new plugs,
wires, cap, rotor and coil anytime soon.
To your problem, any friends that have a diag puter for it, thats
probably the best way. You say there is pressure, is there gas coming out
when you push the schrader or just air pressure ?? I could have sworn I
saw cheap diag puters in the local National Auto parts store for like $50
or so, by manufacturer. You could spend a fortune shotgun trouble
shooting it.

new cap, rotor, wires and coil. Finally strapped it to a shop 3 miles
away [now I know why straps are no good for towing, they make nasty
noises when they go under the towed wheels] and paid $80 for a diag,
turned out to be the ECU under the w/s washer bottle, plunked down $90 at
National Auto and stuck it in. At least it does not need new plugs,
wires, cap, rotor and coil anytime soon.
To your problem, any friends that have a diag puter for it, thats
probably the best way. You say there is pressure, is there gas coming out
when you push the schrader or just air pressure ?? I could have sworn I
saw cheap diag puters in the local National Auto parts store for like $50
or so, by manufacturer. You could spend a fortune shotgun trouble
shooting it.

It is OBD - I, and the diagnostic tools at the local auto parts store don't
connect. The tool at the store cost $150, so I bought one, but it wouldn't
connect to anything.
