Feels like you shut key off my mechanic says its losing spark cant figure out why
Sounds like the same problem I have been having with my 2002 Sedona for
the past 6 or 8 months. It would run OK for several days, weeks, or months,
then just quit. If I let it set for 10 to 20 minutes, it would restart and run fine
for at least the rest of that day. About 2 weeks ago, I was fortunate that it happened when someone was with me, so I was able to determine that it
was not getting any spark. Since then the problem has gotten worse and
more frequent - it was happening almost every day and would take over
1/2 an hour before it would start again. This morning was the last straw.
I drove for about 4 miles and it quit. Took 1 hour and 10 minutes before it
would restart. Drove another 2 miles and did it again. This time it took
1 hour 35 minutes before restart. After 1 more mile, it quit again. Took 2
hours, this time. Made it another mile and BAM! - did it again.
My bro towed me home. I determined that it is most likely NOT the crankshaft position sensor, because 99% of the time they either work,
or they don't. Very rarely does it cause in intermittant problem. The most
likely suspect is the engine computer. That was always a likely culpret
when I worked on GM cars. Today I installed a $50 junk yard engine control computer. I am crossing my fingers!
I will know on Thursday, as I have a 50 mile trip to make.
I will post again on Thursday, to let you all know.
Well, the engine control computer didn't fix it. I made it about 5 miles
and it quit. I am waiting for the junkyard to call me to let me know if they
have a mass air flow sensor. I will know Saturday morning.
OK. Final solution. I figured it can't be the mass air flow sensor, because
if I unplug it, the car starts and runs. I sat down and took my time trying to
figure out what could cause this problem.
I know a camshaft position sensor will make a car not start, but not quit running once started. The crankshaft position sensor will make it quit running.
Since both of these sensors are behind the timing belt cover, I decided
to replace them both, along with the timing belt if needed. I found all three
on the internet for $147+ including shipping. It took about 2 hours (didn't
need the timing belt - looks like new - sent it back).
Drove it about 15 miles the next morning without a hitch. Then drove it
another 18 miles that evening and had no problems. A couple of days later
I drove 35 miles - still OK. After 3 more 30 to 40 mile trips it seems to be OK.
It's been 2 weeks since the repair and all is well, so I have to assume that
the problem is resolved.
Now I need to replace the cat converter and all of the O2 sensors, and maybe
the check engine light will go out!
i also figured mine out replaced the cam sensor. no problems since
