Well still haveing issues. A couple of good things have come out of this so far. Found a few things that need tending to. One was fuel pump. could not get power connector off and damaged plug on pump. Kinda figure this was my problem with engine cutting off. Pump was failing do to bad connector and or pins. Ordering a new pump.Seems as though I have had more than one thing causing my problems with car.
I also had the SDS cause a cut out issue, simply disconnecting the electrical connector fixed that too until I put a new sensor in.

SDS?

Ahhh. Think I might have solved it . Again gonna save judgement till it runs for a couple of days. Got fuel pump in record time from rock auto. Ordered sat. got it today and installed it. car ran well and held 18 psi of boost with no issues.Tomorrow I will replace spark plugs and fuel filter. I think I need to clean and or replace AIS as well. Car Idles down to zero sometimes.And I found out something . If you add 6lb of boost you need to add 6 ld of left to the steering wheel when to step on the gas.!!!!!! LOL
Well back to the drawing board. After changing fuel pump car ran great. Ran great today till I went to lunch and it cut out again. Did it on way home as well. also would run pig rich (9 afr) then go lean(16+afr) for a sec. and back to 14 afr.Only thing I have not done to the car is change AFPR. Any comments are wellcome. Oh yeah I have only code 12 but light comes on for a sec every now and the. Mostly a low rpm.

The only thing I did diff. From the time car wasnt running, from friday till yesterday when I installed pump. Was just that. I didnt start it at all. Why a couple of days not running would make a diff I dont know.
Things I have done to solve problem.
swapped from cal'd computer to stock along with map.
swapped 3 bar with brand new one for cal'd computer.
replaced coolnt temp sens
replace fuel pump
replaced fuel filter
replaced spark plugs. old ones looked fine.
And could the SDS cause this issue?
Well guys . Dont have a clue whats up with car. And now my radiator sprung a leak!!!!WTF!!!! Anyways. While its down Im gonna redo vac system and injector harness.Talk to Shel and see if cal wont support FFV injectors with a larger throttle boddy as well. My even finish port matching new head to two peice intake and intake to thottle body. You guys have fun. im gonna be busy for a while.
Keep us updated. This is a rough one for sure.
Well cordes . I was pulling apart front harness to see what was up and found that the black wire from smec to on of the pick up coil plugs was broken at a splice. Crimped and soldered that back together. Need to check rest of front harness and still getting codes for map and charged air sens . So Im gonna go take back harness apart and see what I find.

Someone told me to check my grond splices in harness awhile back ago. Guess I should have listened.
That should make a difference for sure. Thanks for the update.
Morning. Time to finish tearing through harness. Haven't found anything yet. Hopeing maybe its the TPS. If that goes bad I would think it could send faulty voltage to temp sens and map sens
I'm not sure what 5v feeds are shared in our harnesses, but I do know that they share a common sensor signal ground.Originally Posted by VaShelby
Well Ill check that violet and wht wire then. Think thats the signal ground.
Black with blue tracer is the sensor signal ground for most all of the stuff. You can check on minimopar though.

Wow cordes. That some good stuff . lol. Glad you sent me that link. will save it for sure. When the rain stops around here i will check that sens ground out.
Well one step closer to getting thing right. Had bad ref. ground to air temp sens. Replaced with temp wire and cleared that code. Replaced TPS and cleared that code. Car idles and runs a lot smoother. Thanks for tip on ref ground wire cordes.

Gonna go try installing cal'd smec and see what happens. Wish me luck!!!!
No problem. I'm glad that you have it running well again.
Well, I had a recommendation in mind, but it looks like it probably isn't needed. I'll keep checking back and if symptoms persist, I'll post. Glad you're making progress. The more frustrated you get, the sweeter success tastes.
Mike
Still waiting on that sweet taste of success!!!!!. I have tried everything I could think of. When i get time Im gonna go back through harness leading to distributer and see what I find.Any recomendations would be great at this time. I even installed vac block to insure good vac to systems.
