    I have the exact same problem with the same vehicle. Replaced fuel pump, gas tank, fuel filter, air cleaner, plugs& wires, dist. cap and rotor, 02 sensors, cleaned with fuel injector cleaners, still won't start cold without spray unless been running a while. Leave it sit for an hour, needs spray again. Otherwise runs fine all day.

If it starts with starting fluid, this means the firing and electrical is fine,however, its not getting fuel. I suggest trying the fuel filter first,but, its probably going to be the fuel pump.

Will turn over but it wont start


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.

96 chevy blazer won't start.


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.

I have a 97 Chevy Blazer that will crank but not start. I can get the vehicle started with the help of starting fluid or gasoline put in the throttle body but throttle response while driving is poor. ...


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.

I have a 2002 blazer that wont start. I sprayed starting fluid into throttle body and it tried to start. Would this be related to passlock system?


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

2001 gmc jimmy 4.3l.idles low and will stall when put into gear unless engine is reved up a little.


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 throttle body'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%.
