Check you battery with a volt guage to make sure you still have good voltage. Check the negative and positive cables and ends to make sure you have a good ground at the engine, chassis, and battery. Check your relay center under the hood and make sure all your fuses are good.

    Another thing to check. Unplug the crank sensor and see if the dash functions come back on. I've seen bad crank sensors actually create this problem. The crank sensor is located between the engine and trans. accessible from the pass. side. It actually shorts out the system and keeps other electrical parts from working correctly. If the dash functions come back on, replace the crank sensor.

Jeep compass wont start after fender bender


Is there spark ? Fuel pressure ? Do you know how to test to see which is missing ? Pull a coil an hold near metal on the engine an crank the engine , Is there spark ? If there is spark ,spray carb. cleaner into the engine throttle plate , does it try to start then ? If it does you have a fuel delivery problem . Check electrical circuit for fuel pump !

VEHICLE CRANK, DOES NOT START Change fuel pump, crank and cam sensor, unable to get orb code


Does yours have a theft deterrent system ? SECURITY light on dash ! Before replacing parts you suppose to test for spark at a spark plug wire . check for fuel pressure . You really should take this to someone who knows what he is doing . You already spent more then it would have cost at the dealer !
The Engine Cranks but Does Not Run diagnostic table is an organized approach to identifying a condition that causes an engine not to start. The Engine Cranks but Does Not Run diagnostic table directs the service technician to the appropriate system diagnosis. In order for the engine to start and run, the correct amount of good quality fuel must be properly delivered to each cylinder. The timing of the valve train operation in relation to piston position is also critical, as is mechanical compression of the air/fuel mixture.
The Engine Cranks but Does Not Run diagnostic table assumes the following:
?€¢
The battery is completely charged. Refer to Battery Inspection/Test in Engine Electrical.


?€¢
The engine cranking speed is acceptable. Refer to Engine Cranks Slowly in Engine Electrical.


?€¢
There is adequate fuel in the fuel tank.


When you turn the key to the on position does the check engine light come on an go off after a few seconds ? Did you check EFI relay in the under hood fuse / relay box . Why are you unable to check for OBD 2 codes ? Don't you have a code reader ?

Isuzu trooper duty 1995 loss of power wont rev over 1800rpm


the cars come with many diff. engines. and EFI systems that match it.
so cant help you.
but ill answer in pure physics.
1: lost DC 12v power to the EFI system causing spark and fuel losses.
2: lost engine compression. 1 or more cylinders.
3: lost spark or never doing a full tuneup every 60k at least.
4: bad fueling, too much or too little.
what do do is a few simple tools to discover the truth.

do you want to gue$$, or test.

They replaced my car with new battery but still stalling - no power at all. What do you think is the problem?


power?

electrical power, as in dim lights
or engine power, like you can go up a hill fast wide open throttle
is it just quick loss of engine power or constant.
hot engine cold engine or both.?

stalls come on may ways.
1: lost DC electrical power lost to EFI system.
2: lost compresson, fails hot?
3: lost spark , try a 60k mile tuneup now, if skippped, they are critical.
4: bad fueling

there are simple tests for each failure path./
do you want to, do you have tools, ???? or just want guessing../?????

ok , i will guess, warning all of mine are wrong.
1: the Fuel pump regulator is bad stuck wide open and fuel pressures
is 1/2 spec at 15psi, car is gutless all the time.
one down 49 to go..

No power won't hold idle


stalls. (hot engine, cold engine, both?)_what engine of the many.?
lost engine power. sure that will stall any motor.
ever tune it up r, or do the 60k mile service points, EVER?
if car was serviced, we can then say
Stalls.
1: lost 12vdc to EFI and spark , did dash lamps all go dead at stall.
can you save the stall with a fast right foot. (big clue there !!!)
2: lost compression hot. (guage it)
3: lost spark. (tests)
4: lost fueling, or floods more simple tests, ask if not known.
5: EGR main valve stuck wide open.
6: ISC stuck closed but will not stop power, or fast right foot.

lost fueling can be just the skippped, 60k fuel fuilter swap.

No check engine light, occasional temp guage malfunction, and it wont start after i have already replaced the fuel filter spark plugs ignition pack and crank shaft sensor. why wont my 2001 saab 9-3 viggen...


still could have a fault in crank sensor wiring ,,, you need to plug in diagnostic tool when it wont start and see if you have a engine revs reading ,,, also check if fuel is getting to the engine ,,,, that car also has immobiliser so try spare key to see if problem goes away ,,,,,, wont get codes on that age group unless problem happens when driveing

My gmc safari wont start. I was driving and it lost all power. would not start back up. replaced fuel filter and spark wires.


remove a plug wire. install a plug . lay it on the intake and have someone crank it while watching for spark. no spark. turn key on see if your fuel pump comes on . you should hear it. If not you could have one of two things bad.Ignition module which is inside dist or crank sensor by the crankshaft pulley. hope this helps. you can have the module tested at oreillys or auto zone.

i do believe that's what it is if it will not let get a diagnostic or if it will not let you access the computer the computer is bad.

Wont start,not fuel problem


hi , i think i have the same problem as you, my engine light flashes and i cant get fuel through the injectors but i have fuel pressure and spark. try these two links which might be helpful, the first explains about the mitsubishi ecu used in your vitara, basicly saying they're **** and break down quite early in its life and the second explains how you can run your own diagnostics test using a paper clip and counting the number of flashes from your engine light, you then compare this to the chart on the web site to find your problem.

mitsubishi ecu site www.carelect.demon.co.uk/mitind.html
self diagnostic test www.btinternet.com/~j_holland/pages/diag.html

hope this helps you out, karl hodder

My audi80 cabriolet wont start.


Hi anilroop,
Your problem seems to be related to the power connections to the management computer system system..... Get yourself a multi meter and check the battery voltage first....have you replaced the battery?

Sometimes when a vehicle has stood for a long time, oxidization can build up between the battery towers and the terminals....this can cause intermittent faults, such as you're describing....but it's unlikely!....If you find that thats all ok, trace through the cables that connect to the computer....

......There will be an ignition connection....
......A battery connection, which should always have power, even with ignition off.....
.....There will be starter signal and ignition signal.....

.......Check the ground connections and then, and this is going to take time....trace through all the cables from each of the sensors and the controlled units....Make sure that the pump is getting power and that power is getting through to the ignition....

This is a very lengthy topic and I believe it may be a lot easier to do it in stages.....

This is the end of the first stage.....keep in touch and I'll give all the help that I can.....

Best regards Johngee10
