SOURCE: is there any way to test the injectors on my 98 chevy S10 4.3

DID you put in new gas, fuel treatment, new sock on fuel pump, all new fuel filters, buy inline fuel pressure gauge, check for codes?, this is not a carb where you pour fuel at it , do you have a repair manual for your truck and have you checked troubleshooting guide?

If you changed your plugs, etc. and know that you are getting a good spark then it's really only 2 other things to check. The compression in that cylinder and the fuel. Check fuel pressure with gauge hooked up to Schrader valve on fuel line next to your distributor ( it has a black threaded cap on it). If pressure is good then you have either a dirty or clogged fuel injector or the injector quit working. Let me know what you find. Anytime you get a misfire in a particular cylinder, you should always check for spark, fuel and compression.

I have a 1998 chevy express van.i have spark and fuel up to the trader valve.the van is not getting gas to start.i am thinking it is the fuel regulator module or the fuel regulater. what do you think?


Put a fuel pressure cage on the Schrader valve to test for fuel pressure. The fuel pump may not be running up to snuff or the regulator may be faulty. The strainer sock on the pickup tube in the fuel tank may have collapsed which will restrict the fuel flow.

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.

98 ford escort just died while driving


Hi!!
If the starter cranks up, your problem is going to be the fuel pump. On the fuel line or fuel rail, by the injectors, there should be a small screw on cap (like the one on the tires), unscrew it to expose the Schrader Valve, just like the one on the tires. Place a piece of cloth in front of it, with a small screwdriver or similar tool, press the valve stem to relieve the fuel pressure, you should see a stream of gas coming out, If little or no gas comes out, have someone turn the ignition to the RUN position, DO NOT START THE VEHICLE, gas should pour out for the 2 seconds the pump remains energized. If gas comes out without pressure or no gas comes at all. Check Fuel Pump Fuse and Relay, if they are both OK, the fuel pump needs to be replaced. If when you press the Schrader Valve and gas comes out with full pressure, your problem will be in the electrical side.
Keep me posted! Good Luck! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

She cranks, then catches but will not stay lit. acts like there is no fuel, but there is fuel at the discharge side of the filter


you need to know how much fuel is actually getting to the injectors. if it's throttle-body injected you should be able to observe a basically uniform conical fuel spray from below the injectors in the throttle body. if multiport injected, you can't see injector spray, but you can attach a fuel pressure gauge to the schrader valve in the fuel rail to see if the fuel pump is putting out adequately. if you don't have a gauge, my favorite redneck method (this is technically a bad idea, so please use all common sense if you do this...no smoking, no open flames, keep all spark plug wires attached, etc.) is to depress the plunger on that schrader valve w/ a small screwdriver for about half a second; if you get pretty wet w/ gas then your pump's probably ok, but you might have a problem where the injectors aren't getting the proper signal from the computer
