- '93 Limited
I have a crank/no start on my "new" 93 Limited that is driving me crazy. I've looked at LOTS of posts and want to start simple first. When I turn on the key, the fuel pump runs and has 34 psi at the fuel rail. When I turn the key to start, the engine starts for about three seconds then dies (but keeps pressure on the gauge). If I crank again, no start at all. BUT, if I turn the key off, then on again, the fuel pump pressurizes, and if I turn the key to start, the engine starts again for about three seconds then dies (and won't restart). Pressing the accelerator down is no change.
Question: if after the X tries to start, if I bleed out the fuel pressure, then crank, should I get more pressure? Or is that only when the car starts?
And maybe the history of this problem might give one of you an AHA moment that has a simple solution. I bought this X because I needed to switch to an automatic due to bad knees. It has 107K on it. I drove it for a while and everything was great. I started getting a hesitation when starting and I thought it might be a clogged fuel filter, since I know it had been garaged and I have been putting seafoam in the tank. Then it quit and would not start. I had it towed it to a recommended mechanic who works on older cars. He tested and there was only a trickle of fuel coming out of the fuel filter. He changed the filter, still just a trickle, so he changed the fuel pump. It started and ran great for about three minutes, then died, and has never started since.
No CEL codes.
If one of you has a brainstorm about this, I will be eternally grateful.
Hopefully this is one of those Occam's Razor things where the simplest answer is usually the correct one. This beautiful green Limited is sitting in front of my house and I think my wife's blood pressure goes up every time she sees it.
