92 E350 351w inconsistently doesn’t start
van inconsistently does not start
the starter will not engage when this happens and it’s pretty new so I don’t suspect the starter or Solenoid.
replaced started main realay
starter and solenoid replaced less than six months ago
checked battery, for corrosion and for current and charge, cleaned and then replace the terminal connections both positive and negative.
Have not replaced the battery wires yet but tI’ve looked into it. Putting it in neutral or giggling the possition of the shifter does not produce different results with consistency of starts. Usually seems to start after sitting for a few hours so maybe running the engine is heating some part of the wiring in the ignition system? Really confused with this issue?

Lets do some basics.
Clean your battery terminals and the main grounds.
Check power to #1
Have someone try to start the van and check power to #3
Have someone try to start the van and check power to #2
IF you have cleaned cable then #1 should have 12V
IF you do not have power to #3 with the ignition switch in the start position then you have a problem back towards the starter switch. Perhaps the ignition switch under the dash mounted on the column.
IF #1 and #3 have power with the ignition switch in the start position and you have no power to #2, then the starter relay is bad. Unless connector #3 is not making good connection.
If you have power to #1, #2, and #3, then your problem is down at the starter or connections on the starter, perhaps ground at the starter.

If 1 2 and 3 have power, the battery lines are all cleaned and have good connection, and the connection to the starter has power the starter solenoid works the starter works but doesn’t consistently get power from the relay which is brand new the by process of elimination it’s either the relay or another part of the ignition right. If it was the ignition switch wouldn’t it just not start at all?

what about the trigger wire at the starter solenoid?
According to RA your solenoid should look like this, perhaps minus the yellow trigger pigtail.
The terminal that the yellow wire is on is the trigger circuit for the starter solenoid.
Hard to diagnose something when it is working. If you haven't already, you need to check all the above terminals for power when the starter will not try to engage or turn.
Do you hear the starter solenoid click when this happens? It is not uncommon to get a bad NEW part these days. Yes you need so isolate which wire is not getting power with the key in the start position.
If I understand you in post #8 "starter works but doesn’t consistently get power from the relay" When this happens have you checked for power at the "S" terminal on the relay?
Would be good to find a starter circuit wiring diagram for your 92!

So when it isn't starting you have power coming out of the relay to the starter? If so you may have a bad winding in your starter. Is there a second solenoid on the starter? When it doesn't start do you notice any dimming in the overhead lights when you try to start it? turn on the radio and then try to start it. I had this happen on my '88 once. Would power everything great until I went to start it then everything would die down. Ended up being a chassis ground corroded. There are 2 main grounds. Engine to frame(body) and battery to engine or body. Extra ground wires are never a bad thing. A new starter doesn't equal a good starter. (Edit, what Annaleigh said lol)
