Question about 1993 GMC Safari

1 Answer

No start. It all started when accelerating down the road it would cut out. Finally after a few days it will not start at all. I have check fuel pump there is 45 lb pres at port on motor. The coil and ignition mod is good. pickup in distributor is good. I put new distributor cap and rotor button on,new plugs and wires, new cold sensor. I can splash gas into top and it will start till that's out then quit.If I take a plug wire off and check spark its strong but is yellow/orange. not blue. Does anybody have a any ideas. Thanks, Wes

You have fuel pressure but the TBI could be clogged. You have spark and the engine runs when given gas. I would look into the TBI. Don't believe it's in the timing either.

Good Luck

I would check the fuel pump or the fuel pump relay I am guessing if you let it sit for awhile it starts then one day stops again and over and over if that is the case definitely 1 or both of those things

Have the shop check fuel pressure at the fuel rail. Maybe the pump impeller has failed. If fuel pressure is good, your timing chain/belt may have slipped.
