Problem with restarting after sitting for half hour.


ever get a tuneup this decade?
is it flooding,
the operators guide says, crank wide open throttle to clear floods
does that work? y/n
if NO check for lost SPARK when it DONT start.
bingo?
if spark is good and not flooding does starter test fuel start engine.
for 3second, not at all , or runs. now.//??

1991 geo storm gsi,Was going down the road fine and all of a sudden It cut off and cannot restart it what could be the possible problem or cuses.


same answer for all cars made 1920 to now.
never restarted ,ever ? gee , a little hint...?
1: lost engine compression hot, (gee forgot to do the 60k serviice/)
2: lost spark , yes, check spark at all 4 cyl. if bad check coil spark.
3: lost fuel or too much fuel called flooding.

one removes a spark plug, it drips of fuel , say all 4.
flooding.
crank motor at WOT, wide open throttle to clear flooding.
if the spark is good and the spark tips are dry, then try test fuel
if car starts and dies. then you lost injection.

easy huh> with the above you know exactly why it fails.
compression bad
spark
fueling.

1991 i think is TBI single injection engine, i can look it up but
no i wont. we need to do the tests first to get there.

1986 throttle body injector floods cylinders when key on. nissan 720 pickup


Maybe the injector is shorted out. At any rate it sounds like it is stuck open. You can do an ohm test of the injector, check it's resistance, but I don't know the value you need to look for on this. Just to give you a range to look for, a Chrysler injector's resistance should be 12-15 ohms. Yours should show low resistance as well. If it's open (no value at all) or if the resistance is very high (high ohms reading), it is bad.

In reference to the last statement in your post, no signal will keep it from flooding. An injector is a solenoid and normally closed. The only way to open them is to complete the circuit across their terminals. As long as the key is on, the injector will have a steady 12 volt current available to the injector on the power side. To pulse them or cause them to open, the ecu will ground the circuit for a split second, energizing the solenoid, and causing it to raise the pintle on the injector for fuel to spray out. The ecu will just keep on its merry way, pulsing the injector over and over, never realising the engine is flooded. If it's flooding with the injector connector disconnected, the injector must be stuck open.
Hope this helps you solve it. Good luck.

My 1996 ford Bronco xlt will just cut off on me while driving.sometimes crank right back . sometimes take a few minute to crank back. and my fuel gauge is not working


Hello and welcome to FixYa!

As a first course of action, I strongly suggest that you replace the fuel filter. It can be clogged by dirt and rust which may cause the blockage on fuel flow. Try to check the fuse of the fuel gauge too. If it's blown the gauge won't work.

If the problem still persists then the problem will be on the fuel float itself inside the tank. You will need to have it replaced to have accurate reading. Replace the spark plugs too for if it's corroded or full of carbon the engine may stall because of fuel flooding.

Hope this helps and thank you for using FixYa! Have a good one!

Truck is fuel injected but you have to spin it


mcdevito75 here, It"s possible but not to the extent the old carbureted engines would flood, Best bet is ti look for a sale some shops run on checking the fuel system, Sears, Pepboys etc.

Won't start, have fuel & spark, black smoke when it was running


Well it is likely flooded. What engine? Fuel injected or carb?

What is causing my 1986 jeep grand wagoneer engine to stall while driving? I cannot restart it but there is power. It will turn over but not start and there is gas in it. The jeep just went "poof" and died...


ok, its and old jeep, cranks but will not start.

carb fueled right? crank it wide open throttle to clean the flood
and block open the choke, if CARB has auto choke, if manual choke make sure its open. (push in knob... called choke)
fuses first. test them.
first check for spark in all cylinders.
if you have spark on all , then its flooded.
if no spark on one try a new spark plug and wire.
if all spark is dead , do the tuneup. now. all spark parts.
if spark is dead, check it at the coil, ? good there? or not.
that is a start.
if the carb is bad, we cant cover rebuilding it here.

stalls while driving has over 50 causes.
but bad spark or flooding tops list. (assumes engine is ok)

1986 flooding bad raw fuel


First try the fuel regulator make sure it isn't leaking and dumping fuel through the vacuum line. it is on the fuel rail near the rear of the engine. Also make sure the ground cable from the battery to the engine block is nice and tight this will cause a flooding condition
