My recently purchased(3 months) base 89 has always started hard when hot(lots of cranking!).I was going to put in a new check valve on the fuel pump soon,but in the mean time its started to run very poorly.The running fuel pressure is 28-30 psi,so we just installed a new fuel pump,filter and the check valve,with NO change.Actually its running well about 10 percent of the time,and very weak the rest..The fuel pressure drops to almost nothing as soon as the car is shut off,so back to the long cranking again.
This car was running as good as any non turbo I've ever driven until this happened 3 weeks ago.My mechanic has no idea which way to go,and I really think its fuel related,as it shows its worst when pulling away from a stop.
ANY ideas from anybody out there is appreciated!!!Thanks!!!!
