    I would suspect the Air Mass Meter, or possibly the idle air valve on those... they get dirty and cause all kinds of weird stuff. You can clean out your idle air valve, the AMM is a bit more tricky -- you can google how to do it, but its a delicate part, unlike your idle air valve.

SOURCE: engine stalls out when put

If the mass airflow sensor is unplugged the on board computer can't read the air flow to the fuel system, hence the dying. Their is a cheap remedy that may work, you can purchase a MAS sensor cleaner and after you pull the sensor simply spray it liberally and it may work again. If this doesn't help you will need to replace the MAS sensor for the vehicle to run correctly.

SOURCE: replaced head gasket,timingbelt,set timing,new fuel

Error code 1-1-3 = bad fuel Injector
Error code 2-1-1 = No O2 sensor signal.
Error code 2-3-2 = O2 sensor signal error
414 - Turbo boost pressure too high
232 - long term fuel mixture too lean or rich at idle
121 - MAF signal absent or faulty.
------------- The codes which you mentioned are bold and underlined.But the other codes which are not underlined,that codes are also other possible codes,which most of the times comes up,with the codes which you mentioned.-------
Replace the O2 sensor. Fuel injectors and maf sensor. Start the car and drive it down the road for 5 minutes. then read the error cods again. ------------ 2-3-2* Fuel trim (lambda control) too lean or too rich at idle }If too rich: high fuel press., leaking injector } ( error comes 113)various driving problems Fuel trim (lambda control) too lean at idle Oxygen sensor( error comes 232).In your cases its both. ------- The maf means mass air flow sensor located on the throttle body.Look at the small rubber hoses from the air intake which go from the large 3 inch air pipe just past the MAF bolted to the side of the engine.--------This 3 parts are to be replaced.This will help.Thanks.Helpmech.

Suzuki vitara p reg, 1600 petrol sport - fuel pump won't kick in need to locate any relays

a NO START CAR right? cranks fast.
what does KICK mean. (looking, what?)
p reg is only UK term, we are usa we dont have UK laws here.

google finds, Sept 1996 to August 1997 = P reg......
as you can see our cars are not yours, at all EFI wise....
the FP relay is on our 1996 was moved from below ECU
to right side of the HVAC heater box behind, glove box.
but our cars are LHD and yours is RHD>
and our cars are OBD2 in 1996 ,participating the move of all parts.
my guess, and can say for sure if you post your VIN tag.
is your FP relay is below ECU.
the socket on all Pre 1996 in usa and canada are GREEN.
and all countries the relay has huge PINK wires there.

on my 97 and 97 the pump does run for 3 seconds, key on
and does cranking, and sure running.
your car also came (options) with a IMMO that cuts the same relay. so the IMMO lights most be watched.
need the book on that. have it.......
sorry i said book , folks here hate books. im told.....

on my 2 car(and my 04) the pump can not be hear easy
keyon, i have to take the fuel cap off , and listen there,
as GF keys on....(buddy)
or I cant hear it. (a good pump is very quiet on this car)
and bad pumps sure do make noise.

what matters is this.
1: fuses good. IG-coil, FI and Dome (memory fuse)
2: battery changed to 12.6vdc rested.
3: key on all warning lamps glow for test. must.
4: CEL lamp must glow, and IMMO not unhappy.
5: key on 3 times and see of the pump gets 12vdc to it ?
yes,? good,
no, its IMMO issue or fuel pump relay bad.
yes, the fuel pressure is next.
if below that , the pump is bad or PFR bad.
if stuck at 60 the FPR is stuck closed on fuel rail. flood city......

we can fix any G16 of any kind .

how is that.?
ask for more, have endless answers and forums covering the whole car. vast data on suzuki.s...

Why does 1998 jeep Cherokee not run unless gas tank is at least half full?

2.5L or 4.0L? engine.
ever do a full service on this car , with a fuel filter.
or wrong gas cap, does car run ok cap off? or loose?
ignore cap off DTC errors. EVAP errors when done, ok?
start with basics.
then check fuel pressure, with a 1/4 tank, is it spec pressure with that brand new filter? yes/no.

the filter is part of the top of pump at top of the FP reg. in tank.
that be how its done. no need to guess. at all.
in this case, the pressure test is after, the cap checks.
the wrong cap will have a missing, cap vacuum breaker this cause
the pump to fail (it cant suck in a hard vacuum at all, get a new cap)

FSM spec, a the fuel rail for pump pressure,
Start the vehicle and note the pressure reading at idle which should be 31 psi (214 kPa).

if the car stalls with 31 PSI pressures , its NOT THE PUMP.
easy huh? just one tool and bam ,hard cold diagnostic facts.
the tool can be had for $20

Runs rough at idle when i drive it runs fine until i come to red light then it wants to stall. if it is idling it will stall to just bought it havent did any maintenance yet

Those El Caminos are nice. If you haven't done any maintenance, I would make sure that the oil is full, check and replace any bad carb. vacuum lines, check for any fuel, intake, vacuum, etc. leaks. Maybe check and replace spark plugs, wires, dist. cap + rotor, also check timing, etc. Good luck.

97 dodge ram no spark

then i would replace whats called the hall effect sensor its that black plastic plate you see when you take dist cap off. just pull rotor and lift up the sensor.dist cap is what holds it on.also under the sensor will be a stamped sheet metal piece that looks like the top of a castle wall. make sure its not loose on the shaft.if it is then new dist will be needed

I have a 91 Cadillac with a 5.7 tbi. Fuel pump occasionally comes on for 2 sec prime, but car will stall after 5 seconds. Other times there is no voltage at pump, either to prime, or when cranking. Seems...

there is a unit called a fuel pressure regulator that controls the FP operation
when the pressure is low it starts the pump and when the pressure reaches a preset value it switches the pump off
AH-- I hear you say the pump works when it has direct 12 volts
true but the engine runs on quick start but not from fuel supplied
that is probably because the pressure switch is not working and there is no pressure for the injectors
IF you were to bring it to my shop , that is where I would start looking for the problem and I would recommend changing that pressure switch

Motor stalls when driving then starts and stalls right away.

Replace the distributor's magnetic pickup located inside the distributor surrounding the distributor shaft, the only other thing thankfully on this ignition system if memory serves me on the f 150 straight six 300 cu inch is the dura spark ignition control box, of course do the obvious tune up parts replacement dist.cap rotor,plug , sparkplugs before spending the $40.00 - $50.00 bucks on the dist.. pick up, you may have a weak a fuel pump check for adequate fuel pressure at carb 7 - 10 lbs.
