228,926 miles on our car. Always ran great! I'm a former GM line mechanic turned Carpenter so I have a good grip on automotive repair. Unfortunately there is always that one situation that baffles even the best of us.
Here's what I have so far.
Wife driving car and it just up and quit. I get there and check for spark. Yup got spark. Looked a little weak to me (orange not blue), but it will jump from the coil to the frame (aprox. 1"). Pulled #1 and plug is wet. Smelled and it is fuel fouled. All plugs same condition. Cranked motor to blow out cylinders and LOTS of fuel kept coming out of all plug holes (WTH!! This car is FI, not carbed!).
Towed it home (After searching this forum I am now praying that the trans is ok) and started diagnosing. Determined that in tank pump is toast. Replaced and still will not start. Plugs are still fouling with fuel.
I have read everything 740 related on this forum and some snippets of info on others (that don't even compare I might add). So far everything I check indicates good.
I don't have any pressure testing equipment to check the fuel pressures with. Is there a "shade tree" method to do this?
Any other advice would be greatly appreciated.
Best, Smitty

Lifes' lessons I have learned:
Never get on anything that doesn't have brakes.
Believe none of what you hear, and half of what you see.
You can count your REAL friends on one hand.
If you can't do it right, don't do it.
Never threaten. Just em hit as hard as you can and run!

Your local auto parts store may have a loaner fuel pressure gauge available. I know a certain Irish-sounding company usually carries them.
The two things I can think of that would leak fuel into the cylinder are the fuel pressure regulator (into the intake) and the injectors themselves.

Thanks for the reply! Are you saying that the pressure regulator will dump fuel into the intake rather than force it through the injectors?
