No Start after a year off

Ugh, so the 2001 came off the road for a while as it got retired from DD. The gas in the tank turned and I didn't start it for a year because of that.

I dropped the tank and noticed a mouse nest around the fuel pump. They started to eat the insulation, I rewrapped everything there. Poured out 10 gallons of brown gas, refilled with premium, stabilizer and MMO. Pulled the plugs, MMO in the cylinders before cranking. Now, nothing. Cranks fine, fuel level is giving wonky readings. The pressure purge in the fuel rail drains good gas, so it appears to be pushing fuel in. Plugs looked ok when I pulled them. Only hint is an intermittent P0340. Fuses look ok.

Where do I start? Thanks!

Almost noting in the way of specialized tools out here in the middle of nowhere where I parked the thing. If I can't figure it out this week, I'll start getting involved next week.

I'll pull the rail tomorrow and verify spark.

Re: No Start after a year off

Autozone will rent/loan a fuel pressure tester for $150. Harbor Fright sells them for $20. Don't know if either of those are options for you.

Advance sells a Lisle inline spark tester for $15ish that's pretty good.

I've got an ACE hardware, a bait shop and a ratchet set. That's about the extent of it.

Re: No Start after a year off

So, with the distributor rail off and a plug stuck into it, I see no spark while cranking.

Gonna go find the CPS and see what I can see.

Re: No Start after a year off

You likely won't see spark testing like that since it has to fire 2 plugs at once. You have a test light I'd check for coil flash at the connector when cranking .

Use a vacuum hose in your ear to listen to the injectors while cranking. Crank and Cam sensors (and ASD relay and the ECU) control timing for spark and injectors both, if you have one or the other then they are good.

Since it's been sitting so long, try unplugging the CPS connector in the engine bay, clean it up, and try it again. Maybe you'll get lucky.

I can't find the darn thing. This is an 01 with the pre cats and there is an O2 sensor connector where the CPS is supposed to be. Internet has been less than helpful in locating so far. Found one diagram that suggests it is passenger side on the engine? Dunno.

It has a permanent CPS code now.

Re: No Start after a year off

So CPS plug sits below the vehicle next to one of the O2 sensor plugs rear and down from the sensor itself. Plug looked clean. Unplugged and plugged back in a few times. Code returned with each crank. Think I'm going to come back next week with a new sensor and the rest of the necessary tools.
