1991 Ford E-Series Van Wet plugs

Lack of spark. no before you get it running, change the oil and filter, then a new set of plugs and wires, then to test for spark, remove the fuel pump relay so you dont soak the new set! Start with the basics, and work your way up, Last tune up was? Wires plugs ALL filters? If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!
