98 gmc jimmy would not start cold unless i spray starting fluid

My 98 gmc jimmy would not start cold unless i spray starting fluid in the air box and then it is fine. You can also just bump the starter instead of turning it noramlly and it will start. It has been to two shops and both have told me they have no clue and to take the truck no charge. I know they checked the fuel pressure, the computer has no codes, the injectors, sypders and just about everything else anyone can think of any advice will be helpful.

Car wont start without spraying starting fluid in it


I would check the compression. As air compresses it heats up. A trick I've used on cold diesels is to bump the starter trying not to let the motor actually turn over, so you keep compressing the same air. Do that a few times then try starting.

1992 gmc jimmy wont start unless i spray with starting fluid after it starts it will start every time untill the next day then i have to spray again ?


Fuel pump issue.--

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

98 gmc jimmy only start when primed at the throttle body then runs fine until shut off then needs to be primed again to start


This happened to me I had to spray Starting fluid everytime eventually. Starting fluid wouldn't work after awhile. Its the fuel pump. Even though it comes on and works its not producing enough fuel pressure to start the engine. It's probably giving about 12-13lbs of pressure but it needs atleast 14lbs. of pressure. And a word of advice to buy a ACDelco original fuel pump if you don't want to have to replace it again in 1-2 years, it's more expensive but will last.

200 GMC Jimmy was hesitating while driving and then completely stopped running. would not restart.


if it is still cranking but not firing the first thing to check is fuel delivery. get a can of starting fluid from parts store and open the air cleaner box. spray fluid into half leading to the motor while someone tries to start the engine. if it fires you may have a bad fuel pump. good luck

sounds like a bad pump you can have it checked by a shop with a scope , they will check it from the pattern to volume and press. even though you hear it doesnt mean its working as it should.
