No fuel pressure after shut down
Ok, I'm the guy with the hot starting problem. I've been doing some
tests and I found some interesting things.
The car is an '87 5KCSTQ with 168k miles. First of all I found a small
tear about 1/4 inch in the turbo to intercooler hose - good thing I found
it since thats a prime way to get crap into your engine.
More importantly I noticed there is no fuel pressure after I turn the car
off. I loosend the fuel pipe at the warm-up valve - no pressure. Tried
the fuel filter - no pressure. Removed the fuel filter and alot of crap
came out. I will change the filter tomorrow.
I think perhaps the fuel accumulator isn't working or the fuel pump is
giving me problems. How can I test these components. The car starts
great when its cold and starts fine if its hot and I start it within 15
minutes. Past 1/2 hour and its really really hard to start - takes about
2 minutes. Someone else mentioned it could be leaky fuel injectors buy
the lack of pressure doesn't seem normal.
Any ideas guys? I don't mind searching the archives if someone has
encountered this before.
