Yes, a Jerk Pump and a Fuel Injection Pump are the same thing. Unit Injectors and Common Rail systems do not use a Jerk Pump.
yes the fuel injector relay is the same as the fuel pump relay.
A lack of fuel. Can cause your vehicle not to idle. A dirty fuel filter can cause the same problem. The fuel injection pump can also cause your vehicle to not idle properly.
If it is loud (louder than other GM cars of the same era with fuel injection) I'd suggest you get it replace BEFORE you are stranded. Running out of fuel damages the fuel pump. They all do make some noise, but the noise is not "loud" Sometimes the baffels in the tank break and pieces of the baffels lodge in the fuel pump.
there is no relay its a mecanical pump Some late model 1979 do have fuel injection thus requiring a relay. If you have fuel injection relay is the longer looking relay set under the dash on the passenger side. it should be in the same location as the seat belt relay, wiper intermittent switch and horn relay.
1987 was major design change year for the Corolla, and the fuel pump if you have a rear wheel drive with a 1.3 or 1.6Liter engine it has a mechanical fuel pump on the engine block, but in May 1987 Corolla went to front wheel drive and some Corollas, depending on the Trim, got the new 1ZZ FE 1.8Liter (same engine used in Corollas until 2012) multi port fuel injection engine and has a electric fuel pump inside the gas tank. If you had asked "where is the fuel pump on a "1986" or "1988" the answer is easy, but the 5th generation manufactured before May 1987 has the mechanical fuel pump. That is the same year Toyota Corolla went to Front wheel drive. The best way to tell is if your car is Rear wheel drive and a carburetor it has a mechanical fuel pump, and if it is Front wheel drive and Fuel injection it has an electric fuel pump inside the gas tank.
The same year they changed over to electronic fuel injection for all Chevy V-8 engines. Either 1984 or 1985.
On the injection pump gear are timing marks for 3,4 and 6 cylinder engines as the same gear is used in all the engines. To time the pump align the mark with the correct number for the engine with the center of the crank shaft and the center of the injection pump center. Timing should be 10 degrees before TDC on cylinder 1 The injection pump gear has 48 teeth with each tooth representing 7.73 degrees.
I had the same problem in my 94 Chevy diesel z-71 pickup, I finally had it towed and they replaced the injector pump module, not the entire pump. Maybe this will help you, unless your pump is totally fried.
Yes, the smog pump is correctly called an air injection pump. It pumps air into the exhaust when forst started to help the cat warm up.
Yes.
No.
he does the exact same thing :3
