93 2.3l to carb and points

[yonu]

ok I am sure this has come up before but I would like to know what I would need to convert 93 2.3l from EFI and coil packs to carb and points yes odd but I am sick of fighting with the EFI and electronics is it as simple as pulling and intake and installing a carb and distributor or is there more to it than that? Also what would be a good donor for parts?

Thanks,

yonu

It's not that simple, unfortunately. You may be able to use some of the wiring from your dash and tail lights, but it requires quite a bit of work to redo everything and would probably frustrate the heck out of you.

As for donors...I'd say grab an entire 83-88 2.0 carb truck if you can find one and use the wiring from that...but as for carbs and intakes...you would probably be better off either buying them outright or try to find the intake from an 86 FI truck (the lower part) and then you just need an adapter for your carb...fortunately, these are still available...

There is quite a bit of information on this site for what works with what, but you will need to search a bit...

And you will need to make sure you only have a low pressure fuel pump and/or a fuel pressure regulator may be needed as carbs only require 4-7 psi to work...not sure what the in-tank pump puts out if you have one but if you don't then you can use an electric fuel pump.

Now, as far as the problems you are having with your FI system...it may be easier and less expensive to simply fix what you have...even if it means replacing things like the fuel pump and associated sensors...

You didn't say what was wrong, but there are many people on here that can give you very good advice on how to go about fixing it...but I'd start with trying to pull some codes and post them as well as any symptoms...what you have already done...and whether anything has been changed on the original system...

thanks for the info I have done carb/points to EFI on 302s but never the other way on around didn't realize there was wiring to change I was assuming i would just be removign wiring .

as to my problem in the last 9 months I have had to replace the ICM mnodule 3 times the MAF sensor twice and Cam position sensor once I am just tired of replacing parts to no avail as right now I think I have a coilpack going out

I don't see why not.
Check that you have a distributor hole and there is a gear inside on the oil pump shaft.
If you don't have that then I wouldn't bother, you would need a new engine, well an old "new" engine.

If you do then you can get distributors with points and the intake from an older 2.3l.
2 barrel weber is a popular carb
You will need to change the fuel tank set up for lower pressure.

Won't need the computer, don't think it runs much besides the EFI system on the '93.
Oil pressure, engine temp, battery light/gauge and fuel gauge are all on there own systems.
Still have a speedo cable on the '93 not VSS.
tach would need to be rewired, maybe, might work fine from a coil.

If you have an automatic I am not sure if computer is needed in that year, if manual then for sure not needed.

I myself find EFI and DIS better than points or HEI, and a carb.
I grew up with points and carbs and am very comfortable working on them, but like the new systems better.

A $20 volt/ohm meter is about the only thing I need to find out whats wrong with the new systems.
The CEL(check engine light) is nice as well, and it doesn't mean a sensor is bad, it means a sensor has sent data to the computer that the computer thinks you should look at.
Engine is Lean or engine is rich, or EGR is not right, very cool stuff that OBD.
Beats the heck of of sniffing an exhaust pipe to see if it's rich or lean, lol.

Check sensors first with a meter, never replace on spec, a sensor is usually "telling" you there is a problem, not that the sensor is the problem.

It would be like replacing the exhaust pipe because you were getting blackish smoke from it, carb is running rich, replacing exhaust pipe would be a waste of money
I know that's simplified, but example is correct, find the problem not the symptom.

Got to Agree with RonD the best tool is a mulitmeter, and about a couple of hours on learning how to use it, carb, points = less power and mileage, sounds like you been buying used parts or cheap stuff if your having this many problems, or bad grounds on your truck the more you have the better, take time to go over all your connectors and simple stuff

It depends on if you have an automatic, or a manual transmission (if you have an automatic I wouldn't do it unless you were converting to a manual trans). If yours is a manual trans it can be done but you would need to change the head to a 4 plug head (there are no carb intakes, or carb adaptors for the 8 plug heads that I know of). Your 93 should still have the hole for a distributor, a Duraspark distributor, and module is much better than the crappy points dist, and not that hard to hookup. Then you would need to find an carburated intake manifold. A 1979-85 mustang 2.3 I belive are the best head, and intake to swap out.

If your truck still runs with the efi keep it, and fix it if it needs it, they are not that hard to work on once you learn the computer stuff. Also the state where you live may not let your truck pass inspection without all the efi in-place, and working so you need to take that into consideration.
