Best you can find.... don't wanna cheap out on critical parts. If you are getting spark from the coil, but, not to the plug, I would replace cap/rotor as well, if your plug wires are old, them too.....

 

Well... yesterday I drove out to the dealer super far from my house to get the OEM coil. I like to do ignition stuff in the dark so I waited and before I put the new coil on I checked all the old stuff again. The previous owner said he put new starter, coil, and wires. They all look like recent changes due to having really no dust on them. I pulled all the plugs and they are older copper plugs but they actually look great. Nice light tan/gray and no moisture at all. Ill replace those all today with NGK platinum just because. So before I put the new coil in I checked the spark on center wire into distributor, nice blue white spark (not yellow anymore). The plugs had the same thing! (WHAT THE HELL?!?) Put everything back together again and fired it up and it idled fine for 15 mins with old coil. Shut it down and went to bed.

How could any of this be possible? I still have the OEM MOPAR ignition coil that I paid $86 for. I might put it in so I don't have to wonder when the coil the previous owner put in will go out. Only thing I know about the parts he put in is that the plugs are copper and the new starter is a reman. The ig coil he put in could be a dud brand... My new motto as of two days ago is to bite the bullet and put in the best parts I can find in order to fix it right the first time and not worry about it failing on me.

Maybe the PCM hadn't learned the new CPS because I haven't driven it long enough yet? Should I start to suspect something wrong with the PCM? The distributor cap and rotor looks old and unchanged. I picked up a BWD cap and rotor last minute last night but haven't put it in. Any thoughts on BWD for cap and rotor? I saw alot of reviews about the BWD coil being junk so I passed on that. Im going to go out and run it around today and see what happens.

 

Wonder if you just had a poor connection somewhere, and your fiddling about solved it?

Not sure how well your truck will like the platinum plugs..... some folks have no problems with them, others, get mysterious misfires that go away when good copper plugs are put back in.

 

Just went to start it. It wont start. Its been sitting in the sun all morning and its about 80 degrees right now. Last night it started and idled fine for 15 mins. It was about 60 degrees. Any insight/advice on my previous post? What do you guys think? EDIT: during this incident I pulled a plug and its firing blue.

 

Does the fuel pump prime when you first turn the key on? Can you check fuel pressure? Or injector pulse?

 

Just went out to the van after doing nothing to it all day. Put key in and fired right up. So obviously something is failing in the heat, and not much heat at that. It's only 66 degrees right now. Anyone have any ideas? Even though it was only 80 degrees today when it wouldn't start, the doghouse was off and there was extra heat inside the van.

​​​​​​​HeyYou: thank you for the help. I originally thought it might be a fuel problem. The previous owner dropped and cleaned the tank, fixed the sending unit to fix the gas gauge, and put a new inline fuel filter on. I got a fuel pressure test kit to test pressure at rail when it stalled originally and it held 39psi constantly while driving and after turn off for a bit, about 5-10 mins. I returned the test kit to AZ and haven't checked it in 2 weeks but the pump primes every time. Primed just fine today with no start and just fine just now. I haven't checked injector pulse but will the next time I get in the van.

 

Ok, so I just noticed something super strange while checking all of my wires to my PCM. The PCM that is on my van at this moment is a CARDONE remanufactured PCM #79-7174. I checked out this part online and CARDONE says its for a 1994 5.9L Ram 1500 Truck. CARDONE's PCM replacement part for MY van (1994 B350 5.9L) is 79-8267. So obviously someone has put in the wrong (but close) model computer into my van. Could this be causing all my problems?? What do you guys think?

 

You never actually replaced the ignition coil, correct? If not then that's your problem. Bad coils can work good, bad, at 50%, intermittently, only when cold, only when hot, there is no rhyme or reason to it. Typically when coil is going bad it has either a broken wire internally or a few shorting out. the expansion and contraction of temperature changes or vibrations is all it takes to make it work or not.

 

Thank you Alloro! Yes I haven't changed the coil yet. Im going to go out and put the MOPAR coil in as soon as this Tornado warning passes! Ill keep you guys updated!

 

Put in MOPAR ignition coil. Idled about 3 mins then stalled. Won't start now. Could me having the wrong PCM model be messing with things? All of the MOPAR and aftermarket parts that I have been putting in are for a B350 and not for a 1500 truck like the computer. Changing out the dist cap and rotor now... Gonna go BWD with these because I dont have transportation to the dealer and already have the BWDs on hand.
