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
"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
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
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,
