Started ... it shut right off... restarted let sit and warm up some... drove it about 12 miles... it seemed to have no power... filled up with gas... drove back and check engine light came on... still no power and seemed to have a poping are backfire sound... parked and turned off car... please help!

Check crankshaft sensor.

Just the ECM calibrating. No issues. If it never ever changed you'd have an issue. Sometimes it just takes a while.

If you have a gas can try adding some in case you have been a victim of theft. If the tank seems full, then it is possible that water was mixed with the fuel.

Water and gas have different buoyancy rates and the float could have dropped.

long post.
ill reduce it for you.
misfires. (is RPM below 700 then misfire can be normal) for idle speed controls dead.
ISC the isc controls speed, of idle,.
mine stuck like zillion times, in 400k miles. endless.sticking
mine was a tiny gutless stepper motor drive ISC valve.
the cone valve is side gets nasty and sticks (
(PCV gases caused as seen on all engines)
i clean it.
the proof is the easy press of right foot easy raises idle back to 700rpm and engine stops misfiring.
ever get a tuneup this decade or running spark parts 500,0000 miles
for the new world record.?


now the tricky part of ISC, , fully explained in the SM serv. man.
the PCM learns its behaviors.
it learns all hot start settings and cold
so when you key on, it goes to the correct HISTORICAL spot.
if it can move there(sticks) engine car race.
or run too slow,
cold start would be worse, as hot isc is more closed
so if sticks there closed, the next cold start will be horrid
some newer manuals telly you to add 5% throttle if car is hard starting this is so common.

clean it. end story.

check fuel filter and fuel pump

had that same problem with a honda civic and it was the fuel pump in the tank. the car would shut the power supply down to the fuel pump for some reason so i just jumped it with a toggle switch. what u do is set up the jump from ur dash to ur fuel pump and keep it off. now drive it around till it dies again and flip the toggle on and i bet u it will start right up

Change your fuel filter, it may have gone it's life time and is getting to dirty to let fuel flow properly. Your fuel pump to may be getting weak, if the fuel filter is dirty the pump works harder and heats up and could be over heating the fuel pump relay too. The fuel pump relay i believe is in the glove box behind a panel that say relay, there should be (3) in there and the middle one is the fuel pump's. switch then around after you change the fuel filter and if you get a chance, check your fuel pressure at the shredder valve. Good luck and hope this help's if there is a Auto Zone around you, you can ask to use the fuel pressure gauge to see what fuel pressure you have and they'll have the step by step instructions on how to do it and takes about 5 min to do and will have the fuel filter and step by step to replace that too. Keep me posted, be glad to help.

the 12 amp is for a jump start and the 2 amp is for a trickle charge which doesn't degrade the battery. i believe you have a loose connection either a loose ground cable or the positive cable to the starter check these and tighten if neccessary

I just replaced my fuel pump and it solved a similar problem.

this engine fuel pump prassurae low. it fuel pump celan. Your problem sovel
