The proper fuel for this s-10 is 58 psi to start the vehicle and it will run on 45 psi but not to good .:)

02 chevy 4.3 1500 fuel pressure is 45psi new pump and coil and crank senor pump is 2 weeks old will not start


I have one question first how did you measure the fuel pressure at 45 psi it should be 66 psi .
I would take a good look at the in line fuel filter before I replaced anymore parts .
It should be on the frame rail some ware under the drivers door look for the lines from the pump

Parked 1988 Chevy Celebrity in garage last night. Today it wont start. If I pump the accelerator a bunch it acts like it wants to start and as soon I quit pumping it just turns over. Fuel pump kicks on...


Hello: 1st, pumping the accelerator on a fuel injected GM car does NOT do any good. In fact if you put the accelerator to the floor you put the system in the lean mode ie, reduce fuel. You will need a fuel pressure gage and there should be a schrader valve on the fuel lines/fuel rail where you can connect the fuel pressure gage. The fuel pressure should be about 10 psi if you have throttle body injection. Is your car a 4 cylinder? If its a 4 cylinder you may not have a schrader valve to connect the pressure gage. You will need a high dollar kit to tap into the fuel line. Have someone attempt to start the car and you remove the air cleaner an see if the injector is spraying fuel.

2006 chevy 2500 express cargo van .What is a good oil pressure for this van. it has 150,000 miles runs great


60psi cold / 30-45psi warm is ideal. I've seen (with that mileage) 45 cold/ 20 warm and that's acceptable - anything less start thinking about a new oil pump.

I have a 1999 ford expedition i have been have trouble starting it for a month now changed the fuel filter reset the fuel pump switch checked the fuses all good. It turns and half the time it starts now...


GO TO AUTO PARTS STORE BUY A FUEL PRESSURE GAUGE THAT CAN CHECK FUEL PRESSURE UP TO 100 PSI. LOCATE YOUR FUEL PRESSURE TEST PORT.LOOK FOR SCHRADER VALVE ON FUEL LINE NEXT TO EGR VALVE.PLACE A RAG NEAR THE SCHRADER VALVE AS YOU INSTALL FUEL PRESSURE GAUGE TO CATCH GAS SPILL AS YOU SCREW IN FUEL PRESSURE GAUGE HOSE FUEL PRESSURE 30 - 45 PSI WITH ENGINE RUNNING. THE ENGINE MUST BE OFF HOOK UP THE FUEL PRESSURE GAUGE.IF YOU HAVE TROUBLE THE FUEL PRESSURE GAUGE WILL HAVE INSTRUCTION HOW TO HOOK UP FUEL PRESURE GAUGE.BE CAREFUL CHECKING FUEL PRESSURE IS DANGEROUS JOB.DONT ALLOW NO MASSIVE FUEL SPRAYING WHEN HOOKING UP FUEL PRESSURE GAUGE YOU WILL GET CAR FIRE.

My 2002 Land Rover won't start. I replaced the battery and it didn't make a difference. The alternator is fine. The computer is lighting up like crazy.....what's going on??? Now it doesn't start at all...


For starters, a cheap in expensive thing I would try is put a external 8mm internal diameter star washer (from a local sorce) on the main battery cable at the starter. The star washer sits against the starterm then the cable, lock washer and nut. I saw a lot of this working for a land rover dealer. If that doesn't fix it, check your fuel pressure at the schrader valve above the coil pack ( against the fire wall at the rear of the engine) should be around 55-60 psi. if that is good, check for spark. If you don't have spark, you could have bad coils, spark plugs, plug wires, cam sensor or crank sensor. If you don't have fuel pressure, replace the fuel pump and fuel pump relay (I always do them in pairs). Hope this helps.

Best of luck

I have a 1999 chevy blazer that died and will not start


Looks like you've covered the basics, make sure the firing order is correct with your spark plug wire replacement. Hope this diagram helps.

My 2002 full size chevy engine turns over but will not start. this happens randomly because the last two times it happened, it eventually started up with no repair. i switched the ignition control module,...


Remove a spark plug, plug it into the spark plug wire, attach a jumper wire from the hook of spark plug to ground and have an assistant turn over the engine while you check for spark, If spark is present check for the presence of fuel pressure at the fuel rail, there is an access valve, if you can't aquire a pressure tester wear safety glasses unscrew schrader protective cap exposing the access valve on the fuel rail with key on press in on the pin in valve like you would to drain air from a tire, be careful because the line is pressurized and gas should squirt out possibly at your face I prefer using a screw on gauge. If fuel pressure (30-40 psi) is present, then look for bad connections to sensors and fuel injectors pull of the electrical plugs on sensors and injectors and reattach sometimes this does wonders sometimes nothing, but as you know intermittent electrical problems can be the most difficult to solve on these newer engines.

2002 blazer 4 wheel drive hard to start


If the pressure is slow to rise, you should consider changing the fuel filter if it has not been done in the past 30,000 miles.
Next, disconnect a spark plug and check for spark while engine is cranking. Use a spark tester or old spark plug grounded to the engine block.
Let me know.
