3.1L/Automatic. Car had been running okay, cooling fans only worked when (new)coolant temp sensor was disconnected, and also the car delayed re-engaging gears after slowing down or downshifting. Trans works fine if downshifting manually. Anyways, I was getting off the highway and the car stalled; Started fine, and stalled again when slowing down close to a stop, then started again. Did the same thing again, but would not start. The next day it started rough, and I drove it home a few blocks. Now the car won't start. Checked fuel/spark and both seem good to me. Spark side gapped. Had code for TCC solenoid, but I cleared it and have not drove it to the point it would reset. Has p1406 pintle potions circuit. Pintle works good and voltage changes when pushing it with a screwdriver. The pintle voltage should be.9 volts when closed and 4.5 when open, mine shows 2.5v closed and 4.5 open. Resistance for EGR valve solenoid is good. Carbon build up in plenum that Ive cleaned the best I can(still a little dirty). Wont start with EGR valve off engine. I checked compression on two cylinders and it was at 30lbs, but not sure if I check it correctly. Car had been driving hot for a short period of time. Recently replaced water pump and a/c compressor.
Any suggestion will help.
