Hi there vette lovers..I´m having some trouble with my 90 Zr1. My fuel pressure drops just after my engine fires up, and the engine stalls. Seems maybe like a fuel pump problem, but this symptom only occurs after engine is hot. Both pumps have a staddy pressure of 50-55 psi first 10 to 20 miles, but then if I turn the engine off and restart the engine stalls after a few seconds with pressure dropping.
Would really appreciate some help, ain´t that many zr1 mechanics around here in Sweden..Is the car suppose to run on primary pump? Where is the pump relay located? Read here in the 84-96 forum that the oil pressure sensor could make the pump relay open circuit, does that apply to the zr1. Guess I´m in to some troubleshooting...
Thanks PA..
