Hello from Louisiana y'all
I have a 2000 Crown Vic LX 4.6 L Windsor
Recently the intake manifold cracked and of course blew coolant everywhere
It actually cracked at the fitting where the coolant temp sensor was, yes I said was. It blew the sensor out of the fitting.
Of course I pulled the old manifold off and replaced it
Fairly simple and straightforward right?
Now, the engine was running before the intake replacement.
Now, with the new intake and various other items, thermostat, upper radiator hose, and spark plugs, all of which it needed anyway, it will not start.
First obvious check, fuel pressure. Bingo right at 35 PSI
Next, code check, No codes
Next, spark, no spark, power at the coil leads
Next, injector pulse, No pulse, power at the injector leads
First thought, crankshaft position sensor, Just put a new one in, not without much agony and colorful expressions.
Still no start, no pulse, no trigger voltage at the coils.
Scan for crankshaft position sensor RPM when cranking. The ECU is getting a signal from the sensor.
All fuses and relays appear to be operating as expected, either by testing with a test light or by swapping known working relays.
Still no start.
If anyone has any suggestions on where to go next, PLEASE let me know.
Thank y'all so much
Chris Ellington
