It could be a bad fuel pump located usually under the rear of the vehicle on either passenger or driver side. Or you need to replace the fuel filter may be plugged up.

Good Luck!

98 sonoma 4x4 ,4.3 vortec. won't start.new battery,coil,pickupcoil,cap,rotor,wires,plugs,fuel pump,checked all fuses, and grounds.even checked pcm.


My 98 sonoma would not start if humid and about 70F. There was also no fire when acting up. Finally found a bad connection on the hall pickup sensor from the distributor. I put ox-guard on the connector pins and plugged it back in - no problems. Took about 2 years and $500 in wasted repairs to find this. Good Luck!

2000 GMC Sonoma will not start after standing serveral hours


Check the fuel pressure at the shredder valve, you should have 62 to 65 PSI when the fuel system is primed. (engine not running) With the engine started and running the pressure should drop by 5 PSI, anything less then 62 PSI in your fuel system when trying to start the engine will cause a no start. Note; that try to start a the engine by pouring gas through the throttle body may cause an internal fire in the intake ports and will cause the fuel injectors to melt creating a more expensive problem. As for the fuel pump in the gas tank, it''s held on by and snap ring which you can remove with a simple screw driver. Good luck and keep me posted, and don't for get to replace the wire harness from the frame to the gas tank. It's a $12.00 investment that's worth more then it's cost.

1997GMC Sonoma 4x4 engine cranks but wont start


sounds like a fuel pump problem. take off gas cap and have someone sit in the truck and turn iginition key to on. (do not turn key as if you were starting but to "on only") you should hear the fuel pump engage. if you dont hear the fuel pump then check the fuel pump relay. it is located behind the glove compartment. hope this helps...
