Long story short, my car has sat in storage in a non-heated barn for about 2 months while we got hammered with snow. It started and ran just fine when I put it in storage, but upon returning the battery was dead and it won't start even with jumper cables. The engine is getting fuel(wet spark plugs) and spark, and as far as I can tell there has not been any mouse chewing damage to any wires. I pulled a few things from the ECU thinking something might have been reset due to the battery being dead for so long. Maybe these will be of some help. Some of the specs of my car: MS1E Hi-res, GM IAT sensor, NGK BK7RE plugs, nissan T25 SR20 .86 A/R turbo, wiseco low-comp pistons, M-tuned rods, stock cams. I noticed the MAP sensor is reading a little low, about 61 KPA instead of the 90ish it should be. I couldn't find any visible vacuum leaks.

 

you have a MSPNP?

 

I do not, its an older one. I'm fairly confident that it runs MS1e hi res

 

is it fitted with the 4-bar sensor?

 

I think so, but I switched the setting to the 300 kpa to no avail. I am at around 3200 ft. elevation if it matters

 

its either 250 or 400.

 

What brainey said. Mine was set to 250 when i got it. Switching it raised it to a whopping 86 KPa, Let us know how things work once your get **** figured. Also, My wife has a 03 trailblazer back home..... no evidence of mice, and then mysteriously the heater didn't work... Thinking it was a blower motor, I removed it finding a nest of insulation and rat ****. Highly sanitary. You never know where those little bastards can squeeze.

 

water in tank, try adding a pack of fuel stabilizer and shake the car to mix
