On this relay the will be 2 hot sides. on the othe 2 , 1 will go to the starter. the other goes to the ECM/PCM. It will only be grounded when the ignitio is in the start position. THe ECM grounds it ut. If when you try to start it and there is no ground, the suspect the ECM is shorted out. Let me know because it can be bypassed. But only if all other components are workig properly and it's not guzzling gas.

Car wont start have replaced starter motor and relay and igniyion switch still wont start


What is year--make--model?
Make sure battery has a full charge and battery connections are all good. If your saying starter motor won't crank, check voltage and ground at the starter motor. Usually two voltage circuits at the starter, one comes from the battery, hot all the time. The other circuit goes hot with key in the crank position and in your case, I suppose wired through the starter relay. The relay has two circuits, the load side and control side of relay. The control side of relay needs voltage and ground to energize the relay. The load side of relay, in a diagram shows a line with arrowhead, when relay is energized, that arrowhead line moves to other terminal and that circuit carries voltage to starter. The voltage for load side of relay is usually hot all the time. I can't rule out neutral or clutch switch. The starter motor usually grounds through the engine block. If all voltage and ground circuit for the starter are good, I'd have to make sure the engine isn't seized.
Any testing at the starter, make sure tranny is in park or neutral and functional parking brake is set.

Can you define the action the wire from ignition to starter silanoid performs is it positive or negitive or does it bridge the gap between the 2 termanals


The ignition switch is not connected to the starter solenoid . That wire on the solenoid comes from the starter relay in the under hood fuse / relay box . or battery junction box , an it is positive voltage. The starter is grounded through the engine block. Do you know what a relay is ? When you turn the ignition key to start , that is an input to the PCM - powertrain control module , then if there is no anti-theft system problems the PCM will supply a ground to the control side of the starter relay , energizing the relay . There by sending power to the starter solenoid energizing the starter .
Do you know what How To Test Relays EricTheCarGuy VEHICLE RELAYS Operation Diagnosis Now then what problem are you having , a no start ?

2000 chev wont start at key


I think the purple wire (or maybe the yellow) from the neutral safety switch goes to the coil side of the starter relay, turning it on so power is sent from there to the starter solenoid. You could check for this signal to the relay with a test light. The key must be held in start while you probe the other two terminals for the relay. If the signal is there, either a bad relay or the coil side of relay is not grounded properly. It is possible that the coil side ground is the neutral safety switch-grounding the relay's coil side only in park or neutral-in which case the nagging light on shifter (between off and run, it only works?) may be telling you the safety switch is the problem.

You may need to look at a wiring diagram, Greg. But the starter relay is the last component in the start circuit before the starter solenoid. From battery to ignition switch to "crank" fuse to neutral safety switch to starter relay to starter solenoid to starter-and back to battery through ground. That is the start circuit. Just that the wiring tying them all together makes it complicated.

No ground to starter relay


starter relay don't use a ground. Your starter gets its ground from the bellhousing.

1993 sierra gmc truck wont start... speedometor races battery working and has had the starter replaced. Gages jumping relays clicking, but no juice to the starter...help


If your starter has 2 or more small wires on it you may have switched the terminals. If you have a separate starter relay you can bypass the relay with a jumper cable and send 12 volts to the starters only main cable. It should crank, have it in Park (Auto) or Neutral (stick shift). If the starter does not crank bypassed then the only thing missing is a good ground. Use a pair of jumper cables and try grounding the starter case and connect the cable to a good ground. With the gauges dancing usually a bad ground is the reason, so the jumper cables will help with that problem too, at least for test reasons.

If you had the old starter tested, then you know it was the first problem. But if the old starter was not tested your problem could be a bad starter relay, an ignition switch,or finally a bad ground. Check the grounding of the remote starter relay, check for a plug-in connector off the end of the steering column for corrosion.

01 Jeep cherokee. good battery. new starter. new ignition switch. new transmission range sensor. checked ALL fuses and grounds. starter relay has power. relay has no output signal. has a known good starter...


Ground a test light to negative ( ground ) then remove relay and check for power, then have some one turn key forward as to start vehicle and check again there should be another hot when key is turned to start let me know if it helps thanks
