Hi all,
New member here. My old '86 turbocoupe is bone stock with 330,000 miles on her (original engine and turbo!). I know the original owner. I drove her every day up until a few years ago when it appeared the head gasket was leaking (losing coolant and running hot in summer). She still ran great though. I had just got my '83 Mustang running so I switched to it awhile. Anyhow from time to time I would fire up the bird and keep her going. It has been over a year since I last started and drove her.
So here's my problem: I can't get her to start. It seems like the fuel pump isn't putting out any pressure since the schraider valve under the hood has no pressure at all and no fuel. I checked out your excellent fuel pump troubleshooting guide and shorted the EEC plug lead and it sounded like the pump was running - but rather weakly. I could only hear it if I was under the car close to the fuel tank. I also have my inertia switch shorted for now to eliminate that possibility. I did get just a little burst of engine run so I am pretty sure the ignition system is OK. So I figured I would pull the fuel filter to see if it was clogged. It seems that it is not the problem since I can blow through it easy enough. I noticed that no fuel is draining from the tank with the fuel line disconnected from the fuel filter tank side line. Is this normal? I would expect it to drain easily even with the pump turned off. I just tried to see if I got any fuel flow with the key ON and no fuel filter expecting a flood of fuel under the car. Nothing... no sound and no fuel. Obviously the pump is not pumping. So do I drop the tank to check pump connections and/or replace the pump? Is there a way to run 12V from the battery to the pump relay connector bypassing a faulty relay instead of dropping the tank?
Thanks for any advice.
