pcm?

Noticed my GPS don't cycle while motor warms. Thinking this is why it runs so rough until normal temperature is reached. Could this be the pcm or a sensor? The plugs and relay are working. Help!

If you are for sure on the GPR & the GP's , it could be a biased EOT sensor ... Or you may be running too heavy oil ....

Also , look for oil leaking from the ICP sensor ( right by the lifting ring on the drivers side head )...

maybe the EBPV?
I didn't think the GP's cycled once it has run it's 1-2 minute course on first ignition.
It may be the oil cooler too but I doubt it....but I don't know,lol

I'm in southwest Arkansas. Can anyone tell me what the little square circuit board with four pins located between fuel filter and the oil reservoir for the HPOP does?
