Check and see if there is moisture inside the distributor, if so it may have a crack. Good Luck Tim

Do the fuel pumps have a high failure rate for gmc sonoma 4.3 1996? it was running great last nite and this a.m. nothing, no noise at pump when turn key, but 8-9 volts on the small square three wire plug...


You should have 12v at that wire.Definitely would check for corroded or loose wiring especially on the ground that runs to the frame on this you are for sure losing enough voltage to cause the pump not to work. If possible try running a jumper wire from the battery to the pump power wire which I think is purple or red and see if your pump will activate.

change the plugs and wires but also replace the distributor cap and rotor if you look at the points on the cap they will most likely be corroded and if you look at the wire that goes from the coil to to the cap it will probably will have white marks on it from arking

99 Sonoma. engine light


HAD A SIMILAR PROBLEM A COUPLE OF YEARS BACK.

THE SHUDDER INITIALLY MADE ME THINK DRIVELINE..U -JOINTS..

TURNS OUT IT WAS ELECTRICAL.

MY SPARK PLUG WIRES.

COULD BE THAT OR YOUR PCM/ECM.IS ALLOWING MOISTURE IN, BAD SEAL.

IF YOU TRY THE WIRES, GET GOOD ONES AND SLEEVE THEM.

A CODE READER IS THE WAY TO GO WITH THE PCM/ECM.

SOME MANUFACTURES DON'T LOCATE/ PROTECT THE PCM/ECM ANYWHERE NEAR ENUFF FROM EXPOSURE TO WATER, ROAD SALT/MOISTURE.



IF YOU GO THAT ROUTE

GET GOOD ONES AND MAKES SURE YOU SLEEVE THEM.
