My jimmy wont start unless it use starting fluid,i shoot starting fl.in the throttle body and it starts right up and i can drive all day,but if i let it sit (like at work or just till it cools) it wont start without starting fl. As long as its warm it starts.Fuel pump is at 60 lbs new fuel filter,no leaks,new plenem gaskets,cap rotor,wires,plugs,air filter,coolant temp senser,air senser, Truck was in minor fender bender on drivers side that smashed the fender bumper and grill but i replaced that but it never started on its own since i got it, Any ideas thanks

What is the fuel pressure? these trucks need a certain amount of pressure to start, if low just 3psi it will not start, if you are sure the pump is good then you may bad spider injector. check fuel pressure first and also try spraying starting fluid into throttle body and see if truck starts. the pump needs 60 -66 psi to start the truck.
I'm following another issue like this on a 1996 Jimmy. This engine requires 60psi or more fuel pressure to run. You need to have someone check the fuel pressure at the rail- throttle body with a gauge.
all right, I reccommend you to clean the throttle body with Carburetor-throttle body cleaner the one in autozone it is really good and not expensive follow instructions on bottle and replace air filter if you haven't good luck!
if it starts with starting fluid. its not getting any fuel to engine. first check the fuse and relay for fuel pump. then make sure fuel pump comes on when you try to start it. its only on for a few seconds when starting. then when driving its on all the time. good-day ! fuel filter also if need be.
is very well could be, if i were you i would check the relay, and fuse for the throttle body injector, if thats good, i would change the fuel filter, if no luck there, i would say you are needing a new throttle body injector. See if you can get somebody to turn it over, and see if the injector is shooting fluid down the throttle body, if not you know its fuel related....This week I had a family member that parked his vehicle, went out the next morning to get in it, wouldnt start, 3 days he went without a vehicle, so i went down and looked at it, he was trying to start it with a key he had made.. i noticed the theft light flashing, i had him get his original key given to him by the manufacturer, put it in the switch, and it started right up.. dont know if that is the case with yours, but hey its a thought.
hope this helps
Clean the Idle air control valve (IAC), it's located by the throttle body so the best thing to do is give the throttle body a good cleaning with throttle body cleaner. Do not use carb cleaner, it's to corrosive for the gaskets used on the throttlebody's. Just follow the instruction on the spray can and after your done putting everything back together. Turn the ignition key's to the run position for 10 seconds and then off for 10 seconds to reset the IAC. Start the engine and let idle for 1 min and go for a test drive. If that does not work, turn the ignition to the run position and pull the ecm(BATT) fuse out for 30 seconds and then place it back in start te engine. The engine may stall but let it, don't touch anything. Just start it again and let idle for 1 min then go for a test drive. The ECM is just relearning the sensors like the first time the jimmy was driven off the assembly line. Good luck and hope this helps. Keep me posted be glad to get your jimmy running 100%.
