SOURCE: 1998 chevy K1500 timing runs ok for 10 miles then loses all pwr

1-timing on truck is ajusted by ecm,when u moved it u cause cam sensor code because it detected timing was off! 2-o2 sensors has the role of detecting air to fuel ratio coming out of exhaust,sends signal to ecm wich collects data from other sensors from that sets timing for best performance,if ecm detects something wrong in system data it will give engine code,that code will point at problem area,in your case o2 sensors probably detected lean fuel ratio that points to fuel system,blocked fuel filter or fuel pump faillure,elect,circuit damage,hope it helped!

Check the injector for 12v on one wire. if good check the other wire for a ground witth the key on. The ground wire pulses from the ECM If you dont have 12v from one wire to the other but you have 12v from one wire to battery ground then be sure the ground wire is good to the computer. If you don't have 12 v at any time check for open hot wire or bad fuse. ADD 12v to the hot wire at the injector. DO NOT add to the wrong wire or you will fry the computer

SOURCE: 90 chevy k1500 350 tbi fuel problem starts but wont stay running

try bypassing the oil pressure switch on the back of the block behind the distributor, if there oil pressure switch goes bad it will do this. had one that drove me nuts trying to fix it then figured out I had to buy a book and low and behold thee it was 3 wire oil pressure switch you can't see between the engine and fire wall just behind the distributor and costs 8 bucks to buy new.

Someone will need to check it over when it fails to start. You need to know if it is not getting fuel to the injectors or spark to the plugs.

89 chevy celebrity stalls when turning


Do the following service it should help the stall out.

Engine stalling and rough run issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

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.
