Do you know how to do automotive electrical testing ? Find a electrical distribution diagram at http://www.bbbind.com/free_tsb.html Get yourself a DVOM - digital volt ohm meter and test for voltage , don't just look at fuse's .

The car does not turn over


Steve, you did not give much info. some causes for an engine not turning over when key is turned are blown fuse/relay, dead battery, faulty starter, security locked ignition out, bad connections, etc,etc.
Check the attached links,instruction and guides, Good luck

07 jeep grand cherCherokee will crank, no start, trans over temp, turn key it continues cranking on its own will not start


the starter cranks with hand off the key>?
that is ON its OWN means. this is bad, very bad, if true)
the first steps, are.
check fuses.
check oil level, on engine, and trans if there is dip stick.
is transmission or engine leaking oil? been doing that? CLues?
Then key on, CEL lamp come on in cluster? it must
if not you lost power (fuses)
next is connect the scan tool. to the dash OBD2 scan port called the DLC>
scan it while cranking, id bet dollars to donuts, it shows why it dont start, (engine good)
lost spark DTC
lost CMP signals. DTCs
lost CKP signals, DTCs. (errors.
scan it. and win.
or its all just cash wasted guessing.

A/T oil temp light comes on accompanied with battery ligh. The engine wouldn't start. Toyota 2010 4Runner limited edition


which engine?
2.7 L 2TR-FE I4 (157 hp, 2WD, 2010 only)
4.0 L 1GR-FE V6 (270 hp)
that means the engine stalled, or was real close to stall
800 rpm is lowest on most modern cars.
so ..wow you like to guess, with $100 bills>?
wow.
NOOBS 101 (posted 100s of times)
  1. get in car, turn on head lights , do they work, (yes/no)
  2. yes, turn key, does all those silly warning lights glow (y/n)
  3. does CEL glow, check engine light, if not fuses are BLOWN if above 1,2. are ok.
  4. Is the IMMOBLISER light happy, not telling you its IMMOBILZED? per oper. guide? if yes stop here)
  5. turn the key to start (all this is in oper.guide) does engine starter crank the engine over fast? (y/n)
  6. yes, then its a cranks no start issue, if no,its starter key issues.
  7. Ok it cranks, do you have spark to all cylinders of unstated engine. seen above?
  8. if yes, then try test fuel, if not fix bad spark. scan PCM, see why the scan tool can tell you why it wont start, by cranking any engine, with tool connected, 1996 to now. do so now.
  9. and more, ask for more if you can get to here.

2003 lexus es300 won't start... radio lights and windows work. Tried a jump start, still doesnt work...


Are you saying the engine cranks but won't start, or the engine won't crank ?
If the engine does not crank, you would check for voltage at the starter, the neutral safety switch, and the key switch as well as the ground connections.

Scan tool will not connect to PCM, car has no spark, engine rolls over but wont start


Does your 'service engine soon' (sometimes a check engine) light stay on if you turn the key to 'run' but don't start it? If this light comes on then the computer is getting power. The no spark could be caused by a bad cam or crank sensor. Since the computer on Dodge vehicles uses both sensors for spark, you can't really tell which one is the issue unless you can connect a scan tool. The scan tool is powered by the port you plug it into, which gets its' power from the cigarette lighter fuse.

times the starter will continue to run until key is turned off.
that is starter relay bad or the puter running it gone nuts.
or bad starter
next time when starter latches up, pull the relay
if it kills the cranking its bad relay or puter
if not, bad starter. all in 1min work..
and a very very serious first ORDER fix first problem
runs on test fuel. but you failed to keep it running for the 2 -3 second JEEP RULE.
if you had here is the results. (logic) hard.
1: i can keep it running with spray need a video?
yes, means ASD is not dropping out
2: no? ASD is killing the engine on purpose. and scan tool told you.

cranks no start
you said,
"No codes." if really true , there is no fuel pressure.!
if not true, its done wrong. so scan correctly THIS time.
is the skim light glowing in the dash cluster, if yes, it will not start
by DESIGN. SKIM is the immobilizer and DOES!

you must scan WHILE l its failing, not after, WHILE.
HOW TO SCAN correctly on JEEPS, (no starts)
key on, see scanner working? now, it must, if not ask.
crank or 5 seconds, (1 potato , 2 potata, 3,4,5.
release key, ( 4 and 5 are overkill but why not?)
do not turn key off or say 2 minutes, get PCM time to REPORT.

scan (2008 or newer scan tools work, CAN-BUS certified)
the tool then tells you why the ASD RELAY dropped killing starting (by DESIGN)
try to know SKIM is and option, so.... me blind can see car
http://jeepdied.com/ASD.html

runs on test fuel longer that 3 seconds, by hand, means.
all is working mostly, the fuel pressure gauge needs a jeep hose kit to work so/....... the pump needs power to work,



now the acid tests
i have 2. acid tests lacking a real scan too;..
spark timing light connected up.
you crank and spark dies, AFTER 2-3 seconds into crank/start
cycle means ASD dropped.
connect meter to injector 12vdc power feed its a daisy chain
12vdc dies, at 3seconds of crank, or dies
at 3 seconds of running,
if true PCM did that , and is ASD drop doing that
running any jeep for 1 second on test fuel is a waste of time
it tells too little
learn that jeeps can drop a ASD at 100mph
any time it wants. and only scanning while it drops
tells you why, unless the SKIM lamp glows,
