Hi guys & gals
Here is the problem van with 318 engine turns over but not run
it has no spark, no voltage at coil & no fuel from injectors
as you keep trying to start it cycling the ignition switch every once in a while it will start and runs perfect any where from 30seconds to 5 minutes
then dies & again has no spark no voltage at coil or fuel from injectors

Ive checked voltage at ignition switch & it is fine
I'm leaning to it being the engine controller ?
Thanks

 

Moved to the correct section.

 

Bad ground could do it.
- Battery to block
- Under the ignition coil


Also, check the PCM power cable from battery. There is a pull-apart connector that could be loose of corroded.

 

You will only get power to the coil and injectors for ~3 seconds if the sensors fail to tell the PCM that the engine's turning over.

See if you get spark when the starter starts turning.


Also, be sure there is good fuel pressure and that it holds for several minutes.

 

Check that the asd relay is coming on(and supplying power). As said above it will not stay on so you need to check it as soon as you turn the key or when cranking.
