hello ls1tech....i have a 93 camaro with a full ls1 swap from a 2000 camaro , harness and all, while driving down the road my car just died lost power, so i check the valve thingy on the fuel rail and it has no pressure at all, the fuel pump wont turn on at all, so i check fuse\relay...i swap the relay for the ac relay and nothing, put the original pump relay in the ac slot and i hear the ac clutch flick on. so relay is good so i run down a fuel pump on a sunday and swap it in a gas station parking lot, still nothing....i jig rig the "broken" pump i just took out and it works fine..so now im stuck..the car shows no codes on the code reader and the relay gets 3.5 volts when the key is on, if i give that post on the realy a full 12 volts the pump kicks on car fires and runs fine..i haven't driven it like that but it does idle fine and rev fine...im stuck...could it be a crank pos sensor or cam pos sensor even though the car has no cel or codes? could it be the ecu itself?
