What is wiring diagram of 1990 Chevy suburban starter I have three wires two go on the big post coming out of the soleniod one attached to the small post on the soleniod cart wont turn over


check that you have 12 volts at the big post with the two wires.If you have voltage there then very carefully touch the big post to the little post with a steel rod or screwdriver. If your battery is good then this process will bypass the keyswitch. be careful because as soon as you touch the two post the engine will turn over. The little wire send a signal to the solenoid to engage the starter motor. check the voltage of the little wire dissconnected. when someone turns the key to the start position the little wire should get 12 volts.

Engine will not start.fuel pump does not run. intermittent problem. has been getting progressively worse. have changed fuel filter. checked electrical connectors.need accurate wiring diagram. chiltons...


start by checking the fuel pump fuse and relay. will the fuel pump run for a few seconds when you turn the key to the run position? If so you may need to replace the crank position sensor. When this goes bad the engine will turn over and start, but only run for a second or two then die like its out of gas.

If you do not hear the fuel pump coming on and the fuse and relay check out good then you will have to see if there is power going to the fuel pump. if power is present at the fuel pump plug then the fuel pump is bad

Ihave a 92 mustang that wont crank, new soleniod but need to know where wires go.


The wire from the battery goes on one of the large posts, the wire to the starter goes on the other large post, as well as any accessory wires. Usually there is only one or two that go on that side. The small wire goes on the very small stud. If there are two very small studs, use one, and if it doesn't crank, use the other. One is used for another purpose.

No power to fuel pump or to pump fuse at fuse block


You can get wiring diagrams from autozone.com -- they have parts of repair manuals online. I have the smae problem but the person I got my 88 fox gl from wired up a switch going to the fuel pump that you have to leave on while driving. I"m probably giong to fix this soon. It looks like the wire powering the fuel pump relay comes from the ignition switch. So if the pump side of the relay is good, but aren't getting power, you may want to see if your ignition switch isn't providing power on one wire, going to the fuel pump relay.
