My truck was in a wreck to the left front fender. When I tried to start it after it sits for a while, I have to spray starter fluid for it to start. After it starts it runs great, but when you turn it off it will not “fire up”. The motor is turning over, but it acts as if it can't get gas for starting. Any ideas that you might share?

I have not heard back from you so I will assume you don't have access to a scanner and fuel pressure gauge. I did note in your email that this problem happened after you had a fender bender! It is possible that the fuel pump relay may be damaged! If it is, the symptoms you describe are similar. I have found out if you crank and crank until the oil pressure builds up, the truck may start. What you are doing is bypassing the fuel pump relay. When you crank long enough the oil pressure climbs high enough to bypass the fuel pump relay to start the truck! This is a safety measure built into the design to shut off the engine if you loose oil pressure. The fuel pump relay is located on the drivers side inner fender along with 2 other relays (if my memory serves me correctly) If your truck try's to start after extended cranking replace the fuel pump relay. It is a mechanical relay with points that MAY have been damaged from the accident. The other areas that could be in question may be the computer as well as the fuel pump. When a vehicle is in "crank mode" The fuel has to be delivered in a very rich amount to get the engine to start. After it starts the fuel leans out quickly for proper fuel control. If the computer does not “see” your truck in the crank mode it will not “give” the rich mixture you need to start your truck. Of course it MAY be the fuel pump relay or something a lot more sinister in which professional help may be required!
