It all started as I was driving. The car had 1/2 a tank of gas and I started loosing fuel pressure fast. The car didn't want to start and when it did, the pressure wasn't holding. I do have an adj. reg.
Anyhow, I changed my fuel pump(307), put back a set of good injectors(stock), chip, ecm, and adj. reg. I put on a Bosh 0-280-160-237.
I changed regulators because I applied vacuum to the old unit and it didn't hold. The new unit helped.
I changed fuel pumps because the fuel wasn't going up with boost. The new unit helped.
I changed injectors and no difference.
All the plugs (Cr42's @.35) are dry.
I continued to pinch hoses like the manual says and same result.
Now, I put the car to the "on" position and the fuel pressure shoots up to 45psi and immediately drops. All hoses are new and voltage is 14 at the pump.
I'm out of ideas...Please help.
