Will quit shift into neutral will start but when you come to a stop then engine won't stay running you let the van sit for 2.5 hrs it starts no problem until the next time can this be the coil I chan

Sounds like a possible shift linkage problem. Follow linkage back from your transmission, look for bent levers, broken or bound up pivoting connections. The neutral start switch prevents starting of engine when transmission is not in neutral or park.

need more info does it run warm

might be a burned spot on the starter contacts where the brushes power the motor.
tap the starter to see if problem goes away.
sometimes you can clean the contacts but that is a temporary fix.

Yes this would be a transmission neutral safety switch problem. the switch sit over the post that the shift cable attaches to on the ****** case. Picture below.

if its been a while change the fuel filter and then have the fuel pressure and volume checked.these symptoms are very common for a fuel pump problem.

It is possible that it is coincidence. Check if after revving it would stall after when your truck is in neutral or in park. This is to isolate the problem if it is the engine when in load or the transmission.

Is this a manual transmission? If there are shifting issues it may be the clutch. Other than that have the fuel pressure tested. The fuel regulator may be faulty or there are leaks or bad lines on the vacuum hoses.

Sounds like an ethanol problem.Try some carb cleaner,if that wont help,rebuild on the carb would be the next step.

you need to replace the neutral starting switch on the transmission,it is a screw in type and has a connector with three wires on it,or start your van in neutral.

I am having the same problem... My solution was to check for pending trouble codes, which is a sensor about to go out... Mine was a crankshaft sensor b trouble code PO385 and PO356.. You might want to check it out...I have 80,000 mile today also 03 deville V8 4.6
