SOURCE: SERVICE ENGINE SOON

Sounds to me like you have a fuel issue. Try replacing the fuel filter and run a good injector cleaner through the motor with a couple of tanks of high octane gas. The service engine light can easily be tripped by weak detonation in the combustion chamber, causing very poor performance as well. Good place to begin before you start dumping $$ trying to figure out whats wrong.

Check fuel pump


Is your battery adequate ... at 7 below? Normally, the fuel pump will engage when the ignition switch is first turned to the ON position - without starting the engine.
Does the starter motor turn over the engine?
Has your fuel gauge been malfunctioning?

Any water in the gasoline would freeze at -7, preventing the fuel pump from being able to function if the water / ice is in the fuel pump

I turn the key and dont do eniting ,after 3-4 times she star


If you mean that you turn the key to start but the starter motor doesn't engage the flywheel until the key is turned to start several times, try this. Look under the front of the car and locate the starter motor, which will be at the front of the oil pan. Tap the end of the starter motor with the handle of a large screwdriver a couple of times. If the starter then engages, the starter motor is bad. What happened to the last 99 Caravan (w/175,000 miles) was that a large amount of oily gunk had made its way into the part of the starter that housed the motor brush ***'y, preventing the motor brushes from moving freely and keeping one or more of them from making contact with the armature. The fix was to spray cleaner into the unit. That freed up the brushes and allowed the starter to work. That was a year ago. If you mean that the motor turns over, but doesn't start until you have tried 3 or for times, then I suspect a fuel problem. I have seen a problem where the fuel drains out of the fuel line when the car is off so that repeatedly turning the key to start runs the fuel pump which must refill the fuel line before it can reach the engine. Check the fuel pump, the fuel pump relay, etc. Or, locate the fuel pump relay, under the hood, on the driver side fender. Carefully remove the relay and remove the black plastic cover by lifting the two tabs. Carefully reinsert the relay, sans cover, and have an assistant turn on the key. If the contact "pulls in" then have your assistant remove the gas cap and listen as you manually close the contact with your finger. ( It's okay, the 12 volts won't shock you!) If they can hear a whirring sound, then the pump is working. Have someone start the car while you keep the relay engaged. Hope this helps. Dano

Shouldn't there be fuel pressure with the key turned to the run position? I only get fuel pressure when the starter is engaged and turning the engine over.


no you will not have fuel pressure untill the engine is running

fuel pressure is not required to start the engine...only to keep it running

when you turn the key on the computer send a signal to turn the fuel pump on for a second and prime the engine...once it starts the fuel pump relay kicks the fuel pump on then you have pressure.

I have a 1990 Jeep Cherokee 5 speed. To start it you have to turn the engine over and it engages but doesnt quite catch. You have to turn the key all the way off then over about 10 times before the engine...


I THINK I ALREADY SENT YOU AN ANSWER, BUT IF NOT HERE GOES AGAIN. YOUR STARTER BENDIX SOUNDS BAD. IT IS LOCATED IN THE STARTER. YOU CAN REPLACE IT, OR JUST GET ANOTHER STARTER AND PLACE THAT IN YOUR VEHICLE. PERFORM THE REPAIR SOON SO YOU DON'T DAMAGE THE RING GEAR ON YOUR FLYWHEEL. THAT WILL BE A VERY EXPENSIVE PROCESS FOR YOU IF YOU HAVE IT DONE AT A GARAGE.

Nate, I'm not sure what you mean when you say,"I can get it to whine but not turn over. The starter is trying to get it to turn, but I don't think it is getting any gas".

Separate and aprt from not getting any gas is the fact( if I understande you correctly) that the motor is not being cranked by the starter motor. You say "it whines". You are referring to the starter motor, right? the starter motor should not "whine". If this is what's happening by guess is the Bendix spring in the starter motor is broken. The bendix spring is a heavy spring that is mounter on s worm gear in the starter motor. When you go to start the motor by turning the key the starter motor turn and the spring travels down this worm gear and engages tthe geared flywheel and cranks the engine. As soon as the engine starts the flywheel is now turning the bendix spring faster that the starter motor and the spring kicks back to its original position. If the spring is broken it never engages the flywheel and the engine wont crank.
The fact that you say the starter "whines" is what I would expect you to hear if the starter is at fault.

As far as no fuel flow there are 2 ifs: if you have an electric fuel pump, then there is a problem in the fuel flow. If you do not have a electric pump then the fuel pump runs off of the engines motion and since the engine is not cranking, the pump is not pumping and the fuel is not flowing.

Anything else you can add before we conclude that the starter has to come off?
