distributor ignition module

Where is this on my 93 Ranger? It's the V-6 with traditional distributor and rotor, and no EGR.

4.0l right? if 4.0l it has no distributor and never did however the ign. control module is located drivers side radiator support.

OK, I'll play Mickey the Dunce. Not a huge stretch . What is that thing called that all the plug wires run to ? On the 94 4.0 this is.

It would be a 3.0l V6(2.9l ended in '92), they had distributors from 1991 to 1994 and remote mounted ICM(ignition control module)

It should be located on the rad support in front of the battery, it sits on a Heat Sink, a piece of metal with lots of fins.

It is called a Ford Coil Pack.
On the early 4.0l V6 engines the ICM(EDIS-6) is, as stated, located on the rad support, on my '94 it is on the front side of the rad support, hard to see
In later years the ICM was added/included in the computer(PCM)

Thanks Rond...Blackdemon gets the close but no ceegar award and Andy gets the Mickey de Dunce prize...DER! Assuming the 4.0 is the only engine Ford put in these trucks is apparently a disease.

the fact that in your first post you said no egr lead me to the conclusion of a 4.0l then also has distributor makes me think 3.0l. thats where the confusion i had came from LOL

Well, maybe not a disease but certainly the only real and valid point of view, the 4.0l OHV IS the only engine in a RANGER, while Ford did build them I consider all other non-4.0l "rangers" nissan or toyota knock-offs, I think the 2.3ls and 3.0l came with rice cookers in the glove box, but never looked myself



Just kidding, my first Ranger had a 2.9l, ran great
3.0l has be a good engine as well, there are alot of posts about problems with them but only because there are so freaking many Rangers with 3.0ls, they used the 3.0l from 1991 to 2008

Found the critter and it looks like a MFer to get out. Move or remove the battery, drop the wiring loom from the top of the rad support, then squeeze yer big paw in there. Gotta get mine out and up top so I can rebolt it to the truck and test it. Either my coil or this critter is giving me an intermittent hard miss at low rpms, especially when the AC is putting a load on the engine. Looks stock so I'm betting on another spendy trip to the parts store, but only the multimeter will tell for sure.

dont rule pout dirty injecters! I had a bad mniss R&Rd all ignition components to no avail. Turned out had a bad injector that would let it idle ok but miss when needed on accel.

 

[RonD]

Yes, a dirty injector or pintle(injector tip) could limit fuel flow causing a lean condition on that cylinder which wouldn't be noticeable until engine was under load, lean mix just doesn't have the same power as normal mix so you "feel" that lower power stroke as a miss.
Seafoam in the gas tank once a year helps keep fuel system clean.

Also check distributor shaft, wiggle the rotor, and if possible have someone crank the engine while you watch the rotor, see if it is spinning true, no wobble.
I have come across worn distributor bushing that caused a wobble at certain RPMs which caused mis-fires, these are very hard to track down, lol

 

[tmcalavy]

It's been seafoamed to death, so I'm ruling out injectors. I've got an HEI spark tester and LED circuit tester on order so I can run the rabbit on the coil, PIP, and ignition control module. Thought it was the MAF, ran great with it unplugged so replaced it, few days later the random sporadic hard miss came back, then went, then came back, etc., etc., etc. Hopefully it'll be cool enough to work in the garage on Thursday...FTS day, or this Saturday.

 

[hank857]

I ran seafoam and the injectors were still dirty. Dont know miles on yours but do not disregard the injectors becausae of the prior use of seafoam. Like I said I R&Rd all ignition components, and did the seafoam only to find it was a bad dirty injector.

I've only had a bad miss in my Ranger once...never thought a woman could do those things to an extended...er...cab...now I know

 

[tmcalavy]

Well hopefully some tests will run it down to, or eliminate the coil and/or ignition module. Everything in the dist. looks and feels cool...nice and tight, no wobble or extra play. In the last year or so, I have done MAF and IAC plus temp sensors. Now on the upside, when it ain't missing it runs like a striped-arse ape...it's just the come and go of the miss that grinds my cookies. Cap, rotor and wires are also new and plugs look good. As the list grows longer maybe I'll add fuel pressure check, injector check, fuel filter change. Ah...old Fords like old girlfriends are 'spensive sometimes.
