03 Isuzu rodeo,3.2 Doha v6, fresh rebuild, runs great until closed loop
Fuel pressure gauge, shows 2-5 lbs of fuel pressure consistently. Just put in new airtex fuel pump, shoots fuel across yard, except when i was in the way.:sick: . Still no pressure, clamp off return fuel line, goes to 50. Replaced regulator, ac- deco, still 2-5 lbs on gauge, drove around block, got to temp, boom dead.
So, i do understand what the sensors do, elec eng degree, although, didn’t use it. Still pretty adept at electronics.
Any ideas where i can start, the neighbor likes to call city code on me, because she literally thinks a blade of grass out of place is criminal:blink: , so the sooner i get this running, the smoother life will run for at least two people. Me and the sweetheart, that owns it. There’s no hope for the neighbor.

Thinking low pressure is reason for ecu shutting down car,
My gauge works, because pinching off line shows approximately 50 on it, so I’m guessing the pressure is low. Checked new for for leaking diaphragm, looks perfectly dry.

When it dies and does not start, what is your fuel psi then? Do you still have spark?
If you spray a fuel source into the intake can you get it to start?

Just went out and restarted with new noid light hooked up to #4 injector, started perfect, noid light consistent flash.
Battery fully charged.
Just restarted, 5 min after noid test. I didn’t let noid test, go long enough to warm up engine. Engine started perfect, just as with noid test start 5 min ago. Ran to temp gauge movement, kept foot on gas for high idle, engine immediately started to stutter, lights on dash, was able to keep running with pedal flutter for 5 seconds. Shut down. Won’t restart as before with clattering sound. Considering the ultimate disgrace, tow to honda dealership. Help

Hooked up jumper cable to battery neg. and fuel rail. First start of day so i knew it would crank and run. Ran 200% longer. Temp gauge went to 40 % , and stopped. O2 sensors started reading on analyzer. Thought it was fixed. Rpms at 35 to 4K were smooth until, about 5 min in. Stutter, lights for reduced power, cruise control, and CEL, which would go off below approx 2500. Engine shutdown.
So i put wrench on front crank bolt, to test pintos theory. Turned fine. Glad that one didn’t pan out, no offense pinto! Stayed up half the night sweating that theory out!

Is it possible the ect sensor is bad. It did take the brunt of the overheat when head gasket went.
