Will not continue running


You'll have to figure out if it is a fuel or ignition problem to proceed.
Is the check engine light on ? Have you checked for trouble codes ?
It could be a relay, the ignition module, coil, fuel pump blockage, or a list of other things. Is the oil pressure light on ?
If this is a vortec engine, it requires 60psi or more of fuel pressure to run. Have you checked the fuel pressure and is it enough ?

Injector not working why put new injector new computer new fuel pump does it have injector relay 1987 celebrity


Check fuel pressure. Have you replaced the fuel filter on schedule? Verify that the fuel pump is getting power. Power goes through an in-line fuse, then the fuel pump relay or the oil pressure sensor. (The relay bypasses the oil pressure sensor while the engine starts, but fuel pump power goes through the sensor during normal run operation. If you lose oil pressure, the fuel pump is shut off to protect the engine.) On four-cylinder models, the fuse is in the fuse block (E PUMP 10)
The fuel injectors are connected to the ECM fuse on one side and straight to the engine computer on the other side. Check the connectors and wiring, especially at the injector.

1988 Chevy Truck . . . I think it's a 1500 with a 350 in it, but I'm not sure. I was rolling down the highway last night at 60 mph when the engine quit running. No sputtering, no sluggishness, no...


Have you checked if the pump is actually pumping gas by removeing the fuel line from carb stick it in glass jar and have someone else crank engine . if gas pours out change fuel filter if not replace fuel pump. if you are fuel injected disreguard last. get fuel pressure tester from auto parts store .they will hav specs on how many pounds of pressuere you should have if pump checks out good try replaceing fuel filter.

What you need to do is check you fuel pressure. Go to a local auto parts store and buy a fuel injection pressure tester. The pressure fitting is on the top of the motor its a 3/8 ish sized metal line and has a screw on fitting like a tire valve does. This line comes up from the back of the motor to the right of the distributor and goes down into the intake. Make sure to have a rag handy to catch the fuel seepage. After you connect the pressure tester turn the key on and off three times and read the gage you should have atleast 58 pounds of pressure. If you have 56 pounds it won't run because the fuel injectors are a poppit valve style and need atleast 58 pounds of pressure to operate.

96s10 starting problems replaced throdle position sensor,fuelpump relay,no start shot of starting fluid fires right up and runs


Check the fuel pressure at the shredder valve. You should have 60psi to 65psi with the fuel pump primed and engine not running. Once the engine has been started, there should be a 5psi drop. Make sure the fuel filter has been replaced and that the fuel pump is making at least 60psi. Anything less or more then 65psi will not activate the fuel injectors, the other thing to is that the spider injection system on the vortec are know to go bad and you may have to replace the system. Good luck and keep me posted, be glad to help you get your S-10 running 100% again.

Starts then quits


Was there fuel pressure before you changed everything? It could also be the pressure regulator sticking or bad. When you crank it over and let off the key you should hear the fuel pump run for a couple seconds and then shut off. If it is doing that then I would be looking to see if you have likes hooked up wrong at the back of the engine or try replacing the pressure regulator.
