Question -
Over the last few weeks my 92 GMC S1500 will stall when slowing to a stop.It takes hours before it will re-crank.I think I have had multiple problems.I changed the distributor cap and rotor, and fuel filter. Still stalls. Week later(with no problems)stalls again. This time I think it was just coincidental that the starter went out.Changed it and ran fine till the next morning.Stalled again.Four hours later cranks up and goes. Pulled ignition module and tested good.Pick-Up coil tests good.New spark plugs and wires.Put everything back together, checked the timing and add some berryman's to the fuel suspecting some bad gas.Truck ran fine.Next morning stalled as I pulled out of driveway.Noticed that the injectors are not spraying the fuel.I can hear the pump come on but can't test to see if relay or oil pressure switch is bad if I can't get it to crank. HELP!!!
Answer -
When you say it won't START, Are you saying that when you trun the key the engine is NOT turning over?.

Or does the engine turn OVER but it won't start and run ?.'

If you pour a little gas in the intake will it attempt to start ?.

Answer
Being EXTREMLY careful put a small amount of fuel in the intake and see if the vehicle tries to run. If it does, Your most likely suspect is the fuel pump of which needs to be checked for PRESSURE and VOLUME.

Pull the spark plugs and see IF they are gas fouled.
