Engine rpm increasing 2-500 rpm with no change in acceleration. Tried running without air filter, ran the same, thought I would try the MAP sensor, just disconnected it and tried to start van, wouldn't do anything, re-connected sensor and got a short clicking noise (maybe 2 seconds) but not from starter, then just seemed electrically dead. Lights and dashboard still light up.
Sounds like you found the problem . get a new MAP sensor or take the one you have to the dealer to be tested . Good Luck

i had a problem with all my lights coming on in my 2006 explore took it to dealer to find out that the battery was dying replaced it and they went away

2001 Pontiac Montana, Been in and out of shop a year now. Started when I had a starter replace. It will crank multiple times for a day or two. Not getting any bad codes from computer. Have had every sensor replaced. Let it set for a few days it will crank for a day...the next moring it will not crank for days. Wiring has been run and checked, fuel pump comes on, started is engageing fine. One mechanic said it was not getting fire, he replaced a unit on the back of the engine that usualy goes bad...still wont crank...the next day it cranks. i am about to redy to give up.....but it has low miles. need some help.

Hi, check your hot power wire from the battery to the starter for a short to the exhaust manifold. It may also be shorted to the engine if the terminal has twisted around. You may want to just remove the wire and inspect it for melted or missing insulation. If that wire is OK, the problem may be that the solenoid is shorted internally. Please let me know if you have questions and thanks for using FixYa.

Did you got the ignition switch checked.If ignition switch itself is getting short, then it will not let the car to start.Also get the voltage at starter relay checked.If the starter relay is short, then it will not let the car to start.-------------
Test the voltage at starter.If there is proper voltage to starter this will confirm, whether the relay is issue or not.-----------
To
test the starter try this procedure.
--------- Measure the voltage at the starter solenoid. Place the
red probe on the positive battery terminal on the starter solenoid and place
the negative probe on chassis ground. Have someone turn the key switch to
"START" while you measure the voltage.The voltage should be
approximately 12.6 volts. If the voltage is correct, there is a problem with
the starter. Remove the negative battery post and check the connections on the
starter.But if voltage is very low and less that 12 volts, this
indicates its faulty solenoid.If you follow the wire from starter solenoid, it
will reach the starter relay.That starter relay is a 12 volt part.If there is
no voltage to starter or solenoid then its faulty starter relay.----------
The ignition switch is also a 12 volt part.Check the voltage at ignition switch wiring harness, there should be 12 volt.If not the switch is the issue.-------Also try wiggling the key in ignition key lock cylinder , many a times the lock cylinder gets shorted or out of line or bit loose internally.--------- Getting this possibilities checked will point towards the faulty component causing the problem.-------- This will help.Thanks.Helpmech.

it sounds like the starter motor could be worn out, or could be as simple as the main pos wire is bad or corroded
