Afailed relay will disable the dash lights and warning chimes that normally come on when the key is inserted into the ignition, and will probably be unable to start or turn over the vehicle. 2. Engine will not start. Another common symptom of a problem with the ECM power relay is an engine that will not start or turn over. MEMBER 1995 CHEVROLET SILVERADO. 1995 silverado starter turns but fuel pump doesn't run. No power to fuel pump relay with key on but can jump the relay to get fuel pump to run. No fuel coming from injectors and noticed only 2 volts at fuses ecm1 and eng1 when key on. All other fuses in fuse block show over 12 volts. SPONSORED LINKS.

It is behind the seats. Asa result of the lack of electrical current, there will be no combustion. 2. How To Tell If A Relay Is Bad - Dim Lights. You will be unable to drive in the dark if the relay for your headlights fails. It is possible that the headlights will not work at all or will be too dim to see in the dark. 3. The944 DME relay controls both the engine computer and the fuel pump. The purpose of the relay is to shut off the fuel pump during an accident to prevent the car catching fire. When engine RPMs drop below 200 the relay shuts off the fuel pump. The issue with the 944 DME is that it eventually begins to fail or become faulty over time. Nofuel coming out of the fuel line further confirms a bad fuel pump. 2. Find the wire (circuit) that feeds power (12 Volts) to the fuel pump and with a multimeter in Volts DC mode, verify that 12 Volts are reaching the fuel pump when you crank the engine. CASE 2: The engine did not start, not even momentarily. Thistells you that the relay is bad and needs to be replaced. This is only true, if you have done all of the 4 previous tests: The fuel pump relay's low current circuit (wire 2) is getting power . The fuel pump relay's high current circuit (wire 4) is getting power . That the fuel pump does come on and is producing the correct fuel pressure Thesecond half of the relay is the "switch" that controls power to a particular accessory like a fuel pump or ignition system. In short, when the primary side of the relay (electromagnet) is activated, it closes the contacts (switch) to supply power to operate the accessory. the accessory is bad and needs to be replaced. Some relay's can The2011 Jeep Grand Cherokee has 22 problems reported for fuel pump relay failure. Average repair cost is $730 at 63,750 miles. They said that is has a bad crank sensor and want to replace it Thefuel pump relay is back near the battery. Take a test light and clamp it to ground on battery and then touch each connect on relay with it still plugged up and one of them will acuate the fuel pump. That will let you know if fuel pump is good. Possibly the relay is bad.
