It sounds like the engine management computer is not getting any signal from the Air Flow Sensor. The signal from this sensor is ignored by the computer until the engine has started. Check the wiring plug for a poor connection where it is connected to the Air Flow Sensor, The sensor is located in an alloy assembly on the large tube that runs between the Air Filter and the inlet manifold. It could also be that the engine management computer is faulty and can only be fixed by replacement of the complete unit.

I have a 1997 suzuki sidekick JX 4×4 and it was running fine I had the computer checked and the o2 sensor and a calorie converter needed to be changed so I did that and it was running great and I turned it...


wont crank or cranks fast but will not start???????????????
2door or 4 doors? (wired diffr they are)
its an old car, and most fail this old. "entropy"
first off, 3 things must be good on this old engine.
1: compression. at above 150 psi, 180 warm not 80.
if compression is low an all 4 cylinders (G16b engine) the cam belt slipped, do to owers not changing belt at 60,000 miles !
2: bad spark, test for spark at all 4 cylinder yet? if bad spark
use a scan tool and see why, cranking for 5 seconds. P03xx errors?
at this point the engine runs on test fuel. does it?

3: bad fueling , too much or too little or none)
is engine flooding, spark tips wet,
no dry, and test fuel runs car for 3 seconds.
ok that means the pump is dead, or weak
caused by (again a real 60k tuneup skipped, the filter)
replace filter. omg got 30psi pump pressure,
lets say pump pressure is still weak, lets say 15psi, (failed)
i check pump voltage cranking, omg, got 8v. the wires
behind left rear tail light (2door) pink wires or ground there bad.
ok got 12vdc to pump. but is weak
i then check FPR, fuel pump reg on fuel rail. i find it is stuck wide open, a new FPR gets pressure to 30 running and 40 not running.
fixed.
no the FPR is ok, the pump is bad. (last, pumps is last in my book as the work is long and hard, and why do that if , its not bad. as most all seem to do on forums.)

no start has 50 causes.
see scotty do the TEST FUEL test.

http://www.fixkick.com/nostart.html


we dont know what checked filter and pump means.
1: filter is there and looks pretty?
2: pump makes noise?
we use a fuel pressure gauge for 20 bucks.

all 9 pump tests are here, and the there tests for injector leakdown
and injector balance tests. all off one tool.
not starting can even be, leaking injector, folding 1 cylinder bad.

Refresh my memory, What have you done to the car beside replacing fuel filter? Do you have a fully charged battery? Are you getting spark to all cylinders? Are you getting fuel? I can help you if you tell me what is wrong. Don't assume it's the fuel pump cause there is so much in between but we can see if your Fuel Pump is working. Open your gas tank and have someone turn the car on but without starting it. You should hear a hum for about 2 to 3 seconds.
This means your pump is working. Now you need to find out what is your fuel pressure? A good number is between 65Lbs. and 40 lbs.
Let me know how you make out I'll be on line all day today.

My Mitsubushi Space Star Car won't Start. What can I try?


spark plugs are deep in the head yet you should get all the the old fuel out first, stale fuel wont ignite and will also clogg fuel filter. you need a mix of atleast 70% new fuel even then its not good for the injecters. If its a manual gearbox a tow start is a quick fix although no go for auto's. cant be much wrong if car was fine when parked, plugs-fuel-filter and possibly fuel pump for sure. If that doesnt fix take plug out put in lead and crank engine to be sure you have spark even just put any plug you know works in lead leaving your plugs in engine just to check for spark y turning over engine looking for spark on plug good spark will be blue but any spark is good.

My car wont start,you turn the key , and sounds like it's going to start but it just wont' i already take to the mechanic he had the car for about 2 months i get the car back ; he said it was fix and now...


FIRST GET A SPARK TESTER TO SEE IF YOU ARE GETTING SPARK AT SPARK PLUGS.IF NOT CHECK IGNITION MODULE FUSE.IF FUSE GOOD HAVE CAR HOOK UP TO SCANNER LOOK FOR IGNITION MODULE FAULT CRANKSHAFT SENSOR FAULT AND PCM FAULT.IF ALL LOOK GOOD SO FAR.CHECK TO SEE IF FUEL PUMP WORKING.CHECK PUMP FUEL PRESSURE IT SHOULD BE 41 - 47 PSI. IF NOT REPLACE FUEL FILTER STILL LOW REPLACE FUEL PUMP.IF FUEL PUMP NOT WORKING AT ALL CHECK FUEL PUMP FUSE AND RELAY.IF BOTH IS GOOD FUEL PUMP AT FAULT.BUT SCAN TO CHECK FOR PCM FAULT CODES IT CONTROL SPARK AND FUEL SYSTEM.MAKE SURE SPARK PLUGS AND WIRES IS GOOD. ALSO CHECK FUEL INJECTORS FUSE ALSO.

Car starts, runs rough it will eventually die after about 10 to 15 seconds, or if i try to give it gas. smells like gas. replaced fuel pump/filter


why did you replace the filter and pump?
did something get in the fuel?

check the injectors and spark plugs

in my car someone put flour in the fuel tank and the fuel pump, pumped it into the injectors where it cloged them up

so i had to replace injectors pump filter now it is good

95 Camaro Z-28 starts hard


Need to verify fuel pressure at the injector rail with the engine cranking and with the key on and engine off. Specification is 55 - 61psi. The pressure should build with one cycle of the key. If the pressure is slow to build up there may be a restriction in the system between the pump and fuel rail .
The system should hold pressure without leaking down. If it leaks down there is a problem. If all is good there Checking for a good blue spark at several plugs to verify the ignition system is working ok. A vacuum leak could also cause a hard start issue.
A bad pick up coil or weak crank sensor can cause hard start issues also.
