Re: 92 S10 W Blazer 4WD Fuel trouble
No electrical pressure gauges I know of.
You need to get a pressure reading when it acts up.
Best to tape a fuel pressure gauge to outside windshield or or outside mirrow.
Always keep it outside cab in case of leakage.
And also watch power and ground to fuel pump.
And when it quits or acts check for lose of spark.
Any codes or check engine lights?
