Question about 1987 Chevrolet S-10 Pickup
To be totally truthfull with you i would first have the fuel filter changed to ensure that the fuel pump can do its job properly than if you want to know if the injectors are working the vehical needs to be running then go to each injector and pull the wire from the injector if the engine starts to shake or make a totaqlly different sound than you know this injector is working HOWEVER if there is no change in the way the engine runs than you have a bad injector or the wiring going to that injector is faulty ok>
I dont think that you pump is bad they rarly will not run at all if they are bad they either work or do not work but you can always take the outlet side hose off and get a large container and to catch the fuel in than have sombody turn the key to the on position and see if you are getting good flow but if it looks weak and barly coming out than yes replace the pump ok?
Hope this is very helpful for you.
Best regards mike
