As title says it will not star after I swapped radiators, and was trying to figure out why it was overheating. Maybe water got on something? Checked inside of diz cap, seemed dry, getting spark, getting fuel in rail and out the injectors, checked timing, cam/crank timing, its still dead on, switched my ECUs just to double check with a spare I had around (both are pg7), and still nothing?? I did check the thermostat last night, but I did put the ground wire back on it. Any other suggestions??? Oh, and I am throwing a code 5, manifold absolute pressure, which I assume is because of emissions vacuum solenoids and stuff, which I did not bother to wire up. Anyone know which solenoids I need, and what I can cap off? Would like to delete most of those, if possible, and possibly get rid of the code somehow? Thanks for any help!

 

Nobody???? Bump

 

were you throwing the code before the radiator swap??
