Mess -o- troubles....
Hey guy's
If you remember, I recently replaced head gasket (2nd time) and I'm wondering,
that since I also replaced the gauges with an aftermarket set Incl sensors, leaving the original plugs disconnected, and it now won't fire up. Battery spins starter fine.
Did I screw up something needed by the computer? Water temp and Oil pressure gauges replaced, (because of erratic operation) wired to sensors and 12V power. OEM plugs left hanging.
The only indication is from the water temp which registers 180 deg, the instant I turn the key first thing in the AM. Can't tell anything yet about oil pres., as engine won't start. I'm hoping the Water temp issue is simply a matter of resistance and I'll have to add a resistor to the circuit to lower the gauge reading...
I don't have any means of transportation without this truck. I'm in the boonies! with cataracts, and having eye surgery scheduled this week.
That's the mess -o- trouble
Thanks All!!

Actually, yeah, it would..... With an open circuit, the PCM sees -40 degrees C, and positively DUMPS fuel trying to get a burnable mixture. That will flood the engine in short order, and cause the no start.

You WANT the PCM to see an accurate temp reading, otherwise, the engine will only run 'properly' in a very limited temp range..... You gauge in the dash also gets its clue from the PCM, (2000 model year? Right??) if it read erratic, probably be a good idea to plug in with a scanner, and see what the PCM is actually seeing.
