Question about 1990 Hyundai Excel
The engine stumbles, wont take gas, and then shuts down. I put a new fuel pump on and a new fuel filter. Pump shuts down when the engine stalls, then pumps intermittently with the engine stalled. The car will restart if i let it sit for a long period. It then will run for a few minutes then stall out again, or start running normally. Any ideas?
If I understand your concern, the car stalls and dies, will not restart immediately but will after sometime. This could be anything and the best diagnostic action would be to have the car's computer scanned for fault/error codes.
In any case, initial suspect would be an overheating and/or intermittent electrical component. This would include:
To help you narrow down the probable fault, next time the engine stalls or will not start, pls try below procedures.
Most gasoline engines would need only two (2) elements to run; fuel and ignition (spark) at the right moment. Based on your post, "start running normally", it would then be assumed that the "at the right moment" is good. Next to check then would be for the presence of spark; this could be performed by removing one of the spark plugs, reconnecting the said plug to its wire, let it rest on any exposed metal and crank the engine. There should be a pulsating spark at the end, if yes then problem is most likely elsewhere, if none, then next to check (depending on the engine type) would be the:
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.

It sound like you have an injector problem. the injectors may not be giving the engine enopuph gas to run. so the engine will stall. the fuel pump with shut down as a saftey measure.
have you injectors cleaned and checked for consitancy.
