Need fuel system help

Have a 1987 E150 with 4.9 with EFI. Power at the fuel pump only comes on for two seconds or so when you turn the key on. Not sure what is causing it to stop

To check for spark pull coil wire from distributor, hold 1/4" from engine ground, crank it and look for spark.

Yea, just don't try this without thick rubber gloves on and a good pair of tennis shoes with rubber soles on dry pavement.

Oh yeah---as I remember it only takes ONCE doing this the wrong way to learn that lesson.

Or if you like cheap thrills and having your world rocked grab the plug end of the wire and make sure you've got a good ground.


(Please know that's just being humorous---DO NOT DO THIS on purpose----it's highly dangerous in the right or wrong circumstances.)
