Question about 1993 Jeep Grand Cherokee

1 Answer

It won't start when it is cold but starts fine when warm. Will start eventually if you pump the heck out of it and crank it and repeat quite a few times. I have a 91 cherokee that won't start when it's cold outside. The fuel pump does not energize. Sometimes it will start after 10 or 12 tries. What could this be?

Try cycleing ur key a few times before actually cranking it alot of the time wen a fuel pump is about to go it wont prime cycling the key will prime it. As for the fuel gauge thats part of the fuel pump its called a sending unit and in the jeeps its all in one unit. it sounds like your fuel pump is about to go tho. i had the same problem with my 93 jeep grand cherokee laredo. i replaced the fuel pump and it runs fine now u can get it from your local autozone for about 140. hope this helps let me know

First i would check the crank sensor by looking for rpm's on the tachometer or scan tool if you see any rpm's then crank sensor is good.Then check for leaking injectors and if they are not leaking then you will need to check the ECM it may have failed.

Have you checked Google I found this hopefully it's not your timing or it may be flooded but doubtful have you tried spraying starting fluid into the intake while cranking it

I have trouble starting my 2007 HHR upon initial start-up. it sputters but after a few seconds of that it starts to run fine. I can stop somewhere turn it off and crank it again and it starts fine seems...


this could be a bad fuel pump that has a problem from sitting over night or when it cools down enough.the armature in the pump may be worn and when its cold it has a hard time turning the pump because of it being worn and when it gets warmed up enough the clearance is closer than when cold and works fine.

I have a 2002 chev silverado 2500HD duramax 4x4, The truck starts only when given a shot of quick start in the airbox. After it runs great you can shut it off then re start it fine. It will not start...


You need new glow plugs. Im guessing you live somewhere kind of cold maybe. It starts just fine after running because the motor is already warm. Quick start will work.....or at least it did for me until I used one mornig and went to crank and BOOM. It blew my air filter case to pieces and caught the filter on fire. Starting fluid is not meant for diesel motors. If you cant afford new glow plugs what worked for me is turn on the key all the way but dont crank wait 10 sec then repeat a few times and it should crank unless its really cold out or the plugs are really bad. Trust me thats what it is. I replaced mine and now It cranks right up even when its super cold.

Engine cranks fine, good battery but just won't


check fuel pressure, try cycling the key to the on position an couple of times not the start position to cycle the fuel pump then try to start it. could be the cold start circuit. once its warm does it start easy ?

How old is the battery?
I'm guessing you've changed the oil regulaly In winter do you use 10w30 or 5w30 oil? You should use 5w30 oil. Di you try just holding the gas pedal to the floor and NOT pumping it?
