I have a '90 EFI 5.0 in the EB for 10 years now,, not had many problems.

Now it will crank and run for about 3 seconds and dies, gauge says I have 40 psi at the rail.

Any ideas.??

PM greenbullitt, he might be able to help.

Great Alan Keyes quote. Not enough Alan Keyes supporters out there.

Swap in a new distributor, to eliminate the TFI & pick up hall sensor.

Its really bad gas, or a problem in the tank.

runs fine when I put the pickup line for the EFI pump in the can of gas for the lawn mower.
