Bought this car from a guy who said only problem is it won't start w/o a little ether..should be easy to fix - wrong. Here's the tale...
No stored codes. All new plugs, wire, cap and rotor. TPS is set correctly. All vacuum lines are new and no leaks. New FPR diaphram and adjustable regulator set to 43 psi. New fuel filter and fuel pump relay. New ignition module and coil. Car has no fuel pressure at rails when key is off, I don't know if this is normal or not. Turn key and pressure jumps to 43 then within seconds "a click" then it drops to zero. While cranking, pressure stays at 40. Fuel pump will run if I jump the a and e connectors on the fuel relay but won't if I apply voltage to the G connector on the diagnostic terminal. After a little starting fluid, fires right up and runs great. It should after all the new parts. I've tried to find the answers through searches but to no avail. I'm trying not to sound like a dumb a-- so Vader doesn't put the smack down on me Wanted to take her to a car show tomorrow but the prospects are looking dim. Thanks for any help you can give!

 

If the pressure bleeds off immediately after shutting it off, then you've got a leak that should be fixed. The 3 internal possibilities are fuel pump (it has a check valve on the inlet), fuel pressure regulator (leaking when below set pressure), and injectors. If you don't have excessive fuel in the engine (which it doesn't sound like if ether helps), then the reg and pump are your two possible culprits.

 

Having just changed the FPR maybe that's the problem, but it didn't start before I did that either. It did maintain pressure before though, I thought maybe now I fixed it.... LOL. How could I have screwed up putting in the FPR?

 

I responded to your PM. What FPR are you using? And have you Ohm-ed the injectors? This stuff can be very fustrating, been there done that. five 7kid is correct, the fuel pressure should hold for several hours, and be slowly tailing off, and its most likely what he said.

When you turn the key to the ON position, you should here the fuel pump come on, and the fuel pressure should be about 43psi. Turn the key off, and the fuel pressure should slowly decline, taking several hours to go down to 0psi.

 

Thanks. I am using a TPIS adj FPR and a new stock diaphram. The diaphram was identical to what I took out. There is definitely a leak now. So I will have to plug this first.
