Try the carb cleaner fluid by mixing it with the fuel or spray it at the intake. After cranking the engine a few times, wait for a while and if the engine refuses to start, get some young men to try & start it by rolling the vehicle & turn on the ignition(i.e. if it has has manual gear shifting) till the carb cleaner has got a chance of forced into the injector to clean the nozzles. If this fails then it(injectors) cleaned by maul removal & cleaning/replacing the injector nozzle tips by a qualified mechanic....sodeep

Carburetor on my 85 Deville only one injector works what could be the problem

There may not be anything wrong. On a two-injector throttle body, the second injector acts similarly to a four barrel carburetor. On a four barrel, only two barrels supply fuel until you kick the accelerator pedal down hard for quick power for passing as such. At idle or normal cruise the second injector in non-operable. Only when you kick the pedal down (passing gear in old school terms), does the second injector activate.

I have a 1987 Nissan hard body 3.0 the objector sprayer stopped working. I replaced the fusable links and it worked for about four hours and shut down. All fuses and relays are good. I'm thinking the e.c.u...

Usually if the fuse is blowing the injector is faulty. The injector could be shorting to ground, or the problem could be in the wiring. The computer only grounds the injector to make it work.

89 pickup 22re. no fire on no. 1 cylinder

It could be a fault in the wiring for #1 injector, or a defective spark plug in #1.

All four injectors have a hot wire to them with key on, the same black with red stripe wire is spliced to all four. Check if #1 has this hot wire with key on. The injector ground wire for #1 and #3 is a white wire with red stripe. These two ground wires splice together before the ground wire enters the computer. So the computer pulses #1 and #3 injectors simultaneously. (Injectors 2 and 4 have a similar set up, with a white wire being their ground.) If you have a hot wire to #1 injector, but no pulse on it, but #3 injector is pulsing (putting fuel into the cylinder), then the ground wire for #1 may be broke before it connects with the #3 injector ground. The wires and the splice are probably buried inside the engine wiring harness, so one could check for continuity on the ground side for 1 and 3. With key off, use an ohmmeter and check resistance between the grounds for #1 injector connector and #3-check on the harness side of the injector connectors-it should show low resistance-low ohms value. If very high resistance is shown, trace the ground wire from #1 injector.

My cavalier was working fine until a few days ago, was running errons and after the third stop I got back in my car and it would not start. The starter was old and had died, got that replaced and the car...

Yes, This happens more and more. You can verify this wile your changing the injector by turning on the key after you pull the fuel rail (keeping the injectors on the rail).
Good job finding this. There are a lot of people that would over look this important factor.
Good Luck and God Bless.

91 civic won't start

hi unlikley to computer on the fuel rail there is a pressure relief control valve some are operated by vacuum so check the hoses some are electrical this controls fuel to all injectors it may be open all the time and fuel going straight to the return to the tank if this is the case there is no pressure for the injectors to work the individual injectors you can buy a tool that fits on the injector and connecting loom thats not dear so it lights flash as the pluses open the injectors or get a multi meter the wires that fit on the injector one is ground usually [black or brown] and the other is a 5v live when cranked yates210456
