SOURCE: chrysler 3.3 vin r v6 mini van, starts then dies

Charlie. You have replaced the ECM on your van?.
Kedwin,, Your problem is, the computer on that 3.3 L.
Need to be programed with the VIN nember of your car.
The Antitheft System will disable the injectors due a incorrect VIN, Bucause the body computer is not recieve the correct pasword between 5 seconds after start up.
YOU have 2 options. 1 get a ALOHA Smith. some of they have the computer required to program ECMs.

The other option is: Get a new ECM from the dealer, They will program if ask for that.

NOTE:::::: Other way is . Put the body control module with the computer from the same car.

OK... I hope this work for yours.
If NOT letme know I can look for more information.
Thank you.

SOURCE: 98 astro van starts and dies immediately. Spark

The first thing i would do is replace the distributor cap and rotor. They are a real common problem on these engines.

SOURCE: Buick Regal dying

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

SOURCE: engine died & wont start no spark ignition coil tested good

try your ignition module in the distributor much more likely. just install rebuilt distributor if that is the problem , if you just replace module the main distributor assem will **** out shortly after.
Make sure you check for broken timing belt also it is one of those two!

My 1998 Ford Explorer 4.0 ohv manual trans starts then immediately dies.relays-good fuel pressure-good fuses-good new fuel pump idle air control valve new egr help!

THAT HAS A HUGE LIST OF CAUSES BUT BREAKS DOWN TO
THE BIG 3. (we find it with tools) otto cycle Gasoline/petrol
  • bad engine (compression good?)
  • bad spark ( try new cap,rotor , wires and plugs?or 6x coil pack./
  • bad fueling or bad fuel. , fuel pressure at spec?
top cause is no tune ups done in 24 years,
all spark parts are bad. (no engine told)
all fuses good/?
test #1 is can you keep it running with a fast right foot actions.
i dies and repeats, or dies and needs to sit for hours to repeat this start fail act./
there were 3 engines then/
4.0 OHV v6
4.0 SOHC v6
5.0 v8 (uses twin quad lug coil packs) and hv wire sets. spark
no engine told so no why to get specific at all just ASE basics basics above.
try a tune up, at least, HV wire sets and new spark plugs gapped right.

and scan scan the PCM see if P03xx errors are stored there.
key on.

Got a 2005 Nissan Altima it run for a bit can come up to a stop sign it will just die take 20 min before it will start again

well you need to identify what is missing. An engine needs ignition spark, fuel and injector pulse to start. (assuming mechanically the engine is ok. Like good compression and cam timing ok) A fuel pressure test is needed to see if it has good fuel pressure. Test for spark and injector pulse. If the fuel pressure is ok but it doesn't have spark or pulse it is usually and crank position sensor but on Nissans it could also be a faulty cam position sensor. Without the proper test equipment you will need to have a qualified mechanic diagnose it for you. I wouldn't start throwing parts at it.

2004 olds alero. new fuel filter and plugs. still wont start.

Did you check for spark at any ot the spark plug wires/ coils? If there is, check for fuel pressure at the fuel rail. Take the port cap off and connect a fuel pressure gauge. If one is not available, with a pocket screw driver deppress valve at port and observe if fuel pours out. If no fuel comes out at all, check your fuel pump circuit. Check for good ground and power at fuel pump connector. If power/ground are ok, replace fuel pump. If spark and good fuel pressure is present, there is the possibility of engine mechanical issues(jumped) timing chain). Also, a plugged catalitic wont let engine start but its very unlikely thats your problem. Start with your basics: spark, fuel, engine mechanical and catalitic.

Cranks but wont start. Fuel is good, spark is good, new starter, new ignition coil on no.5

Is the fuel good or is the fuel pressure good?
How did you check for spark - are you certain it's firing the plug?
Why was the starter replaced?
What is the condition of the spark plugs?
Did you have a check engine light?

Swinging but not starting

cranks but will not start.
test for spark at all cylinders.
test for spark still timed, #1 near TDC, #1 firing. at near 0 degrees.
if the spark is good and timing is good, try test fuel.
if spark is timed wrong, the cam belt or chain slipped.
i have no fiat data. but above is generic.
if spark is good (are spark plugs new and not color black (tips)>
ever do a tuneup this decade?
if an engine floods, crank with WOT, wide open throttle.
(pedal to dah metal)
this clears the flood by cutting all injections of fuel.
if engine is not flooded, try test fuel.

see scotty do his magic.

2013 Sienna starts and dies. No fault codes. If I give it more then 50% throttle and play with it It will stay running. Anything less and it dies. Starts up normal but dies almost immediately. No Antitheft...

no fault code where? on the Pro OBD2 scan tool screen>?
should be in warranty, why not let them fix it?
tow it there.?

bravo that, first post ever with fast right foot test, you are on the ball.
ok, that means this.
1: it's not losing 12vdc power to run the EFI. all lamps are not dim.
2: the fast foot test, implies to me, spark is ok, (unless one cylinder shut down, a bad COP?. but the scanner will see that for sure and did not. Gross misfire, is never unreported by the scan tool. (PCM)
gross enough to stall the engine.
so fueling issues.
id check for flooding or starving for fuel. and bad fuel.

Ok so my guess, is its losing fuel pressure or you got bad fuel.

My 93 blazer wont run? i can put my hand on the upper intake and it starts then it dies instantly.the fuel pump checked out ok. the engine is a 4.3 liter

There is a injector spider under the intake,this,or the fuel pressure regulator could be the problem,so you might just check this out.

Engine cranks. sparks but does not start. fuel pressure ok

Have you replaced the crank sensor? The crank sensor on top of the trans. bell housing does control the injector pulse through the ECM.
The sensor is a common problem with the Jeeps. Sometimes the sensor stops working when the engine is hot and will start again when it cools off and sometimes it dies from oil leaking on top of it or it just dies.
