After a few miles of driving it acts like the ignition cuts off and on faster than you can turn it off and on. It's a pretty hard jerking not just dropping a cylinder. It has a new fuel pump, coil, cap wires and rotor. I have also replaced the crank and cam sensors. This is driving me nuts. Any ideas ? This is a 1996 Ram Van 318.

 

Think these mid 90's vans need to see the Pope ! I've replaced all that an then some .Starts some days some not ,runs 5min. then dies , at time 20min. then dies ???

 

Look up the TSB to properly place the ignition wires. Geno's garage will have it.

Also, some of those power inverters can cause the same havoc when used too.

 

My 2000 Ram Van, 5.2 was acting squirrely. Replaced plugs, wires distrib cap, rotor, coil and no improvement. I was getting ready to check fuel pressure thinking it was the fuel pump. My upstream NTK oxygen sensor came in the mail so I replaced it. Took it for a ride and it goes like a new van. Keeping fingers crossed! A little over 100,000 mile on the van. FYI

 

I do have a power invertor as this is a conversion van. Can the invertor still cause this problem even though it is turned off ?

 

Your PCM/voltage regulator maybe going

 

How can you be sure it's the voltage reg. in PCM ? I've replaced every thing but the PCM /coolant sensor/ and MAP sensor..Some times starts an runs at times won't just turns over great ?

 

Is your OBD I or II?


If it is II then if you have this code stored - it is your PCM
