Default Hard start when up to TEMP?

Thought I would run this buy you guys, my 88 starts right now when first start up but turn it off then wait a min. and it cranks for 5 or 6 sec. before it starts. Runs fine after it starts though.
Why?
My thought is one or mutiple fuel injectors my be leaking a little after start up. but just a guess have not pulled any plugs to see if any of them are fauled out.
Any help Thanks

Your guess is probably correct, hard warm starts are usually injector-related.

Hook up a pressure gauge at the rail, crank the car cold, note where the pressure stabilizes. Then turn it off and watch the pressure, it should hold for quite awhile. If it doesnt replace all 8.

Ford injectors are made by Bosch.

You want the Ford SVO 24lb injectors and an adjustable regulator, preferably the Holley unit (summit PN's are on my website's 86 page, click my name)

Do NOT buy accel.
