My 2000 Honda Civic CX will not start with the Map sencer Pluged in
you meant, car will not run right (unsaid)
so i unplugged the MAP sensor (forcing limp home mode)
when was last time car had fresh fuel.
when was last time car was a daily driver?> last week, last year?
by removing the map the limphome goes huge rich state.
so id say , the engine is in a very lean state and going to limphome
hides this situation.
why not post full symptoms , with all parts back on engine.
did do the 60k mile , tune up yet? if the cam belt snaps, say good by to a good engine. (boom) Timing belt, sparks and filters.?
1: cranks ok.?
2: wont start
3: is it flooding? or starving for fuel. spark plug tips dry or wet.
if spark is good all cylinders, (no engine option stated) then
i check timing, if off the belt (cam) slipped.
if the engine is flooding i do the flooding tests.
if its to lean i do the lean tests.
ASK .
for the lean test i check the ECT , then fuel pressure.
the fuel pressure is 10 tests on a V6.
I can also test the MAP in 5min with a voltmeter, to see if its right.
here is the list ,
Good voltage 12vdc to the EFI starting and running.
Good engine, spec compression,
good spark and timed correctly if, off its the cam belt slipped,
good fueling,
there are simple tests for each.
i also make sure the EGR is not stuck open on all cars with this.
and that the ISC is not dead.(stuck and dirty)
