I am new here but could use some insight into a problem im having with my 94 Explorer.This is my second Explorer the first being a 92 both were good rigs but lately the 94 wants to die at idle.it will crank but no start unless you turn key off and let it sit for a few minutes then it will go agian.it doesnt do it except at idle.usually when its warmed up.some times after youve driven a while and shut it off it will crank but no start until it cools for a few mnutes.any help would be appreciated. Thanks

Welcome to this forum! I've renamed your thread, and moved it into the stock 91-94 section. Clean the mass air flow sensor, and check the engine coolant temperature sensor.

cleaned the MAF added about a quart of coolant and it seems to be fine now.the idle speed is to low but i can live with that for a while.I was told this could be the ( IAC )idle air control motor/valve.

There is a post sticky I believe on how to clean the AIC on here if not use the search. The search can be your best friend here believe me. Also do a fuel pressure test just to make sure it’s all okay and check for any fuel in the vac line from the fuel pressure regulator (FRP) to the vac tee on the intake

i had that happen on my 94 when it happens next turn the key to the on position and listin for the fuel pump fo engage if it doesnt then you have the same problem i did. under the hood there is a relay box the one marked fulel pump relay is the one too replace there ten bucks from napa so if that is your problem then it is a cheap fix hope it helps
