Question about 2001 Ford Explorer

1 Answer

.Engine stalls, won't idle, bucks at 3700rpm

Hard to start, acts like a flooded motor. Will run if my foot is on the gas but stalls when i take my foot off. Reved the motor to 3700 rpm and the motor felt like it was bucking. The higher the rpm, the more the buck.

Sounds like mass airflow sensor to me or your timing jumped. Probably high miles too, eh? Could possibly be voltage regulator but I highly doubt it.

Fuel pump relay wiring diagram

hot engine or cold or both??????????
and #1 all time question on topic, can you prevent the stall with a fast acting right foot.. A KEY CHECK and FACT !
Is it totally intermittent, and runs perfect other times,,,, gee, just a hint here.....???????? if yes, #2 below is probably ok.

can be lots of things, that cause stalls (over 50), not just the fuel pump.
we check fuel pressure if at spec. then i forget that. (easy huh?)
let me make a list . (works on all gas cars)
  1. lost 12vdc power to EFI system (dash lamps go dead?) loose fuse? dead battery, battery lugs filty, etc.
  2. bad engine compression , can happen hot,
  3. lost spark , ever give it a 60k mile tuneup? test spark using SOP ways and means, google it.
  4. bad fueling (note how its last as you can NOT burn fuel with above bad. period. We learn to read spark plug tips for clues.
  5. bad fueling too much is flooding or starving.
  6. EGR valve stuck open will stall any engine , or near stall.
  7. there are up to 50 causes but the above MACRO , covers most.
ever think to use a scan tool and scan it for errors at the stall.
a scan tool can be had for $9 buck.s
or rent one, or barrow one, many auto stores lend them.
in the hope you will start buying parts like crazy, lacking and FSM
and the reading these tests. in said manual.

My car starts fine when engine is warm. I turn it off then try starting it again. then starts up and shuts back off. does it like 3 times in a row. then I wait a few minutes then it starts up when I push...

stalls, are complex
if the engine is good (compression at spec)
it this list.
1: lost electric power to EFI system or spark.
2: bad fuel.
3: bad spark.
4: bad fueling. (too much or too little.
5: EGR stuck open
6: ISC dead. or IAC dead. (idle air valves failing cold)

there are tests for each.
cold start failure only ! all else good, engine tuneup done?
1: ECT fibbing like oh'bummer. (signals water temps of alaska in Panama? "floods, and your right foot helps./..........
2: IAC (cold start fast idle air valve bad) same for right foot....
3: check engine light on running? is it?

ECT can cause gross over fueling.
the IAC dead will cause gross under AIR which in fact causes flooding (less air plus same fuel = flood)
bad fuel.

Everything runs fine except when i idle. when i take my foot off the gas and press the brake to stop at a red ight or park the engine stalls. i think its a battery thing i had corrosion on the postive...

Either your power brake assist booster has a bad check valve in it causing a huge vacuum leak when you step on the brake (Vacuum leaks lean out the fuel/air mixture causing stalling) or you have an 'engine protect' sensor that kills the ignition/fuel pump when the oil level's too low and it's either got crud in it from running the oil too low or has otherwise malfunctioned.

1990 Ford Probe 2.2 automatic stalls in forward, reverse OK

Sounds like a bad IAC (idle air control valve/sensor) that controls your idle when going from throttle to idle. If bad your idle will act crazy and can cause stalls easily. Pretty sure that's it.
