P1492 code....no start

[9 LIVES]

Here's my welcome to vp44 ownership. I've only had this 01 3500 for a couple weeks and now it won't start. Only code its showing is the P1492. I know thst has something to do with the battery but not sure why it would cause a no start. Batteries are less than a year old

driver side battery box was missing the sensor...put a new one in and that did not help. The fan clutch has been out for a while. Could that cause a no start?

2nd gen fan clutch is not electronic. Sounds like you may want to look for open/shorted wiring that has to do with that sensor.

You have fuel psi at the VP?
Will it start on ether and run on fuel?
Check your cam / crank sensor too.

I don’t think the P1492 has anything to do with your no start, at least I've never experienced it.

I think it was 10-15psi during cranking. I haven't tried ether yet. I will pick up a crank sensor tomorrow.

Does the tachometer move while cranking?

It's been a long time, but I think the early 01s use the crank sensor and the later 01s use the cam sensor for primary pickup.

Just checked and the tach does move when cranking.

Are you getting fuel if you loosen injector lines?
