Anybodys guess without any real information. You did not mention how old the cap, rotor, plugs, wires are. Only that you changed the pickup module.
A bad cap with a crack will make it misfire, a badly worn rotor and cap will make it run poorly, bad plug wires with spark arcing off of them will make it misfire.
Worn plugs will make it run poorly.

OBD1 is not really going to give a lot of information .... I do not think it will tell you anything about a engine misfire because the parts are worn.

 

cap.rotor and wires i mentioned were done this summer as i had wires that were arcing out and cap and rotor are bluestreak brass terminals not the aluminum and the complete distributor assembly was replaced in 2019 with an A1 cardone as the old one some one broke one ear off and had a wood screw in the other

 

yeah on crank sensor that is not something i can do as i can't lay under a rig anymore and have limited fund plus finding one of these in the junk yards around me is a needle in a haystack hard to do all this on a fixed income 3 yrs ago i could do all this myself but my body does not permit that any longer

 

Yep. Know how that goes...... I have to pay someone else to work on my truck these days. I simply cannot do it myself any more. I have been medically retired since 2005.... I still work part time at a local computer shop though. The hours are REALLY irregular. Might work every day one week, then not again for three. But, my boss likes me, as I am flexible. Who else could he email at 6 in the morning, to see if they could come in to work, and actually have them SHOW UP? been there for ten years now.

 

i'm kinda wondering if it is a fuel delivery issue although i would not think it is as when i hammer down it takes a sec but she will want to go i am just at a loss as the basic codes it has really don't point to anything that would stand out as far as what it is doing. just at a loss the truck is kinda driveable and went as far as to see if maybe water in the fuel so put 2 bottles of HEET in the tank but didn't make much of a difference

 

Wouldn't be a bad idea to check the fuel pressure to see what you have, especially if the fuel pump hasn't been changed anytime in the recent past to your knowledge. There should be a port to check the pressure at the fuel injector rail.

 

yes i believe there is and sadly i do consistently run it low on fuel. i would have to see if i could get a tester with a long enough hose to reach inside to drive the truck as that is when it acts up.it idles perfectly fine. i do know on these the "filter" is actually built into the pump assembly.

 

While it might be nice to have a long hose to test while driving .... I do not think it is needed.
A fuel pump will typically put out a consistent flow of pressurized fuel .... it may not be as high as is needed, but consistent.
I think my 1993 V6 requires 45-50 PSI at idle ... if the pump is bad and it only pushes 20psi .... that would be ok for idle or drive slow speeds .... but not enough for higher speeds.

The fuel pump is electric, you turn it on and it does it's thing ... driving does not make the fuel pump work any differently then at a idle.
Also my 1993 Caravan 3.3 has a fuel pressure regulator on the fuel rail ... if not working correctly and stuck open, could cause low fuel pressure. You probably do not have that, but worth checking to see if you do have a regulator. .... thinking most put them on the fuel pump.

 

thing is when it starts "acting up" if i floor it it hesitates for a sec then bam takes off like a rocket.that is why i was thinking maybe at certain load or something is when it happens I don't know and as stated nothing in the basic codes it puts out really points in a specific direction

 

this is part description o regulator:

Dodge Ram Fuel Pressure Regulator

The fuel pressure regulator alters the pressure of the fuel supply in your Dodge Ram when you are driving. The fuel pump delivers pressure at a consistent level, but appropriate fuel pressure may be determined by the speed of your vehicle. Higher RPMs require more fuel pressure to keep the engine in your Ram running, the fuel pressure regulator alters the pressure to the appropriate level for your driving condition. If the fuel pressure regulator fails, sticks, or clogs, you may experience black smoke, fuel in the exhaust, or engine stalling. Check the fuel pump and fuel pressure regulator, and if the regulator has failed or clogged, it should be replaced.
