Question about 1999 Chevrolet Silverado 1500

1 Answer

My 99 suburban wont start without starting fluid

It wont start when the motor is cold. And if its cold outside its almost impossible to get it started even with starting fluid. The only time it will start is once the motor is compleatly warmed up then shut off. If started while motor is still warm or hot it will fire up. I know its just a sensor. Its got a new batterie, plugs, wires, and cap and rotor button.

I had same problem. Engine will start if you crank it for awhile. This is because the fuel pump has a . check valve that is supposed to keep fuel from running back into tank and hold fuel at pressure so it will start immediately. If valve leaks it takes awhile for fuel to be pumped back up to injectors. Replacing fuel pump fixed my problem.

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.

what is the fuel pressure with key on and engine off? since you mentioned spider injector assembly it has to be a vortec engine that requires 55psi to open the poppet valve in the injectors just to start.

98 astro awd doesnt like to start in real cold weather (-18C) otherwise runs fine


I have a 98 and we just had a cold snap where it was super cold and I didn't start it for about a week. I had just got a new battery because mine tested out bad. Everything was good but now it doesn't want to get fuel. Cleaned all battery and relay connections and it's turning over great and fires with starting fluid but won't start. Guy at Napa said the fuel pump on these are known to not work well in the cold and suggested to warm the tank. I'm parked outside and can't move it to get it inside somewhere. Anyone know of good solution to this fuel pump not working in cold temps issue?

Citroen c8 wont start when its cold


probably your crank position sensor is bad. it determines the position of crank and adjust ignition timing. when timing is off it wont start.it cant catch. this is unrelated to outside temperature.

Has spark but wont start even when i use starting fluid


I'm not sure of the vehicle type or model due to your question, but the fact you mentioned spark I can only assume its a gas powered engine. I would highly recommend you not use any type of STARTING FLUID to aid in starting. Starting fluid should only be used for diesels, and I mean large industrial size motors when cold only. Any type of starting fluid used on a gas engines or domestic sized trucks can severely damage the engine especially when it won't help at all with the issue it won't start. Need more info of vehicle to help.
