No fuel pressure - ZR-1 Net Registry Forums

ZR-1 · 01-14-2015

Hello everyone. New member on these boards. I have been having trouble with my zr-1. The car randomly died on the highway. It would crank over but not start. I checked for spark and used a noid light on injectors, both passed. Next I checked both fuel pump fuses, they were good. I then proceeded to check fuel pressure. My readings were 0. I listened for the pumps to turn on while switching the key to on. All I could hear was a real quick click from the tank leading me to believe the pumps were shot. I replaced them last night and still getting the same symptoms. Will be searching for the test terminal today.

My questions:
1. What else should I check or do if the pumps do not kick on with terminal test?
2. There is a four wire harness at the pump. What is each wire?
3. What if the pumps DO kick on? Relay issue I'm assuming?
