Hi' all, my 1991 Dodge Ram van is not running to well and is cutting out now and then and rather than go down the replace this replace that with all the electronic stuff i wondered if there is an ordinary distributor and carb available for this engine so that i can bypass all the fuel injection and electronics to make it all simple?
And if so where can i get them from?
Thank's in advance, DAVE.

Dave,

Before jumping into something that may not solve the problem, look over these TSBs.

Did you check for any trouble codes in the PCM?
How's your fuel pressure?
When is the last time you had a tune-up?
How does it start when cold and hot?
Do you feel any skipping?
When it cuts out, do you lose electrical power to anything?

 

[radical dave]

Thanks for the reply's guys but can i get a normal points dizzy and carb for this engine? I'm old school and i just wanna junk all the cr*p off this van and make it reliable, no i doubt it's been serviced for some time as not many people on this side of the pond know anything about proper american stuff and no-one has the diagnostics to sort out the older vehicles.
I never liked all these scensor's and computor's they just make it so people have to throw money at their vehicle's instead of fixin em' sorry for the rant.
Dave.

 

[stev]

Dave,

Just getting a carb to work on the engine isn't going to do you any good. The vehicle has a computer regardless. You swap the TB out for a carb and other issues/problems will crop up really ugly for you. Even to the point of spending much money.

On all of the Chrysler vehicles made for some time now, you can easily check the compute engine codes without the need to find any dealer or service garage.

Just turn the key in the ignition from on/off three times without starting the engine. On the last key turn, leave the key to the on position. The "check engine" light will flash a sequence of times. Write down the number of flash sequences. Usually, these flashes are in groups of two. An end of code flashing is 55. That is, five quick flashes a pause and another five quick flashes.

Once you have those numbers, we can quickly tell you what the problem is and how to fix it. That's one of the best things Chrysler has for it's vehicles vs. the other domestic American vehicles.

We want to really help you at this problem, but your year has a computer regardless of wanting to swap in a carb.

Stev

 

[alloro]

I'm not sure if it applies to your van, but at least in later years the gauges/warning lights, fuel pump, cruise control, check engine light, etc., are controlled BY the PCM. If you eliminate the PCM, you'll also lose that stuff.

 

[radical dave]

Flippin'ek ! well the haynes book of lie's say's iv'e got 33 air con fault and there's none fitted, EGR diagnostics fault (california models only) van's from Kansas, 42 auto shutdownrelay driver fault, 37 part throttle unlock solenoid driver circuit fault.
So what's all that lot about? As i said i'm old school and all this does my ead in.
Thank's Stev & Alloro.
Dave.

 

[DANVAN]

Im not to good with this new modern stuff either, but I think if u disconnect the battery for a few minutes, the false codes should disapear and then just the actual real codes should come back. I say this because didnt u just replace a bad auto shut down relay? So that code shouldnt be in the system any longer, and who knows about those other codes, maybe they are past problems also? Just my 2%

 

[alloro]

The code 42 could explain your cut-out problem. This code is telling you that the PCM has detected an open for the ASD relay's coil circuit. As danvan pointed out, it could be an old code, but at the same time there could still be a problem with the ASD circuit. The only way to know is to clear the codes and start fresh.

The code 37 has to do with the torque converter lockup circuit going to the tranny. The circuit is open or shorted and you need to attack it with a meter (not literally) to figure out the exact problem.

You can ignore the code 33 if you don't have A/C.

What was the code number relating to the EGR fault?

 

[radical dave]

Thank's again for your suggestions guy's, I thing the fault code number for the EGR fault was 25 not real sure, it's very awkward to read these morse code's for a pleb like me lol. I don't even know what EGR stand's for?
Think i'll try disconecting the battery next, thank's Dan but will have to wait untill the weekend to do it cuz of work.
I still think i could do with a new ignition switch but my parts dealer can't find it listed over here also when reading the code's it's very hard to distinguish between the length of pauses on the flashing light.

 

[alloro]

EGR - Exhaust Gas Recirculation
This system allows a certain degree of exhaust gases to flow back into the intake manifold. The purpose in doing this is to reduce exhaust emissions and reduce pinging in the engine. if the EGR system or valve fails, it can effect how smooth the engine is running and cause stalling at idle.

For the ignition switch, I looked up your 91 and found the ignition switch at Autozone.com (maybe they ship overseas). Anyway, they said on the page that the ignition switch replaces these OEM numbers: 4443924, 4504211, 4797401, 5269497. So maybe your parts guy can look up these OEM numbers and find something.

 

[radical dave]

Thank's alloro i will look into that.
